8d36aad30a Implement constants for all annotation types 
Now we have a full list of all possible annotation types and the
numbering corresponds to the order in the specification. Not only is
this more consistent and complete, it also prevents having to add these
constants when a new annotation type is implemented.

Additionally fix an issue where a regular Widget annotation would not
have `data.annotationType` set. It was only set for a
TextWidgetAnnotation, but instead move it to the base Widget annotation
class to add it for all Widget annotations (since TextWidgetAnnotation
inherits from WidgetAnnotation it will have it too).

ee0d522187 Use adjustWidths for TrueType fonts if we handle them as OpenType (issue 5027, issue 5084, issue 6556, bug 1204903) 
In `Font_checkAndRepair` we can decide that a font isn't TrueType, and instead parse it as CFF. In that case it's quite possible that the `fontMatrix` will be changed, and without calling `adjustWidths` we're failing to update the glyph widths correctly.

4810b7b8fc Fix the charCodeOf method in IdentityToUnicodeMap in order to prevent text selection from breaking 
After PR 6590, `font.spaceWidth` is now called in more cases than before (in `PartialEvaluator_getTextContent`), which exposed an underlying issue with `IdentityToUnicodeMap_charCodeOf` throwing an error.
This breaks text-selection in some PDF files found in the wild, hence this patch replaces the `error` with an actual function instead (modelled after `IdentityCMap_charCodeOf`).

8b79becad6 Improve code structure of the annotation code 
This patch improves the code structure of the annotation code.

- Create the annotation border style object in the `setBorderStyle` method instead of in the constructor. The behavior is the same as the `setBorderStyle` method is always called, thus a border style object is still always available.
- Put all data object manipulation lines in one block in the constructor. This improves readability and maintainability as it is more visible which properties are exposed.
- Simplify `appendToOperatorList` by removing the promise capability and removing an unused parameter.
- Remove some unnecessary newlines/spaces.

995e1a45b8 Ensure that Lexer_getName does not fail if a Name contains in invalid usage of the NUMBER SIGN (#) (issue 6692) 
*This is a regression from PR 3424.*

The PDF file in the referenced issue is using `Type3` fonts. In one of those, the `/CharProcs` dictionary contains an entry with the name `/#`. Before the changes to `Lexer_getName` in PR 3424, we were allowing certain invalid `Name` patterns containing the NUMBER SIGN (#).

It's unfortunate that this has been broken for close to two and a half years before the bug surfaced, but it should at least indicate that this is not a widespread issue.

Fixes 6692.

27c8e1e22f Improve the comment and deprecation warning for PDFJS.openExternalLinksInNewWindow 
This patch:
 - Updates the JSDoc comment in `api.js`, to more clearly point out that `PDFJS.openExternalLinksInNewWindow` is deprecated, and explains what to use instead.

 - Changes the `warn`, in `isExternalLinkTargetSet()`, to use the new `deprecated` function instead. Also updates the message with more detailed information about what to use instead.

 - Changes the pre-processor tag to ensure the deprecation warning is seen in all build types where it could possibly matter (in case people are using `PDFJS.openExternalLinksInNewWindow` in e.g. custom-built extensions).

These changes were prompted by seeing http://stackoverflow.com/questions/33813373/pdf-js-how-to-open-hyperlinks-in-a-new-tab-window, since it seems to me that the current comments/warnings might not be worded well enough.

b05652ca97 [api-minor] Let getAnnotations fetch all annotations by default, unless an intent is specified 
Currently `getAnnotations` will *only* fetch annotations that are either `viewable` or `printable`. This is "hidden" inside the `core.js` file, meaning that API consumers might be confused as to why they are not recieving *all* the annotations present for a page.

I thus think that the API should, by default, return *all* available annotations unless specifically told otherwise. In e.g. the default viewer, we obviously only want to display annotations that are `viewable`, hence this patch adds an `intent` parameter to `getAnnotations` that makes it possible to decide if only `viewable` or `printable` annotations should be fetched.

0991c06395 Refactor annotation flags code 
This patch makes it possible to set and get all possible flags that the PDF specification defines. Even though we do not support all possible annotation types and not all possible annotation flags yet, this general framework makes it easy to access all flags for each annotation such that annotation type implementations can use this information.

We add constants for all possible annotation flags such that we do not need to hardcode the flags in the code anymore. The `isViewable()` and `isPrintable()` methods are now easier to read. Additionally, unit tests have been added to ensure correct behavior.

This is another part of #5218.

c604cc22d1 Improve error message for non-existent local files 
I received multiple reports about the following cryptic error in the
Chrome extension when the user tried to open a local file:

> PDF.js v1.1.527 (build: 2096a2a)
> Message: Cannot read property 'Symbol(Symbol.iterator)' of null

This error most likely originated from core/stream.js:

    function Stream(arrayBuffer, start, length, dict) {
      this.bytes = (arrayBuffer instanceof Uint8Array ?
                    arrayBuffer : new Uint8Array(arrayBuffer));
                                                 ^^^^^^^^^^^
`arrayBuffer` is `null`, and that in turn is caused by the fact that
for non-existing files, there is no data. I've applied two fixes:

1. Never call onDone with a void buffer, but call the error handler
   instead.
2. Show a sensible error message for local files with status = 0.

1c66d4a106 Add a totalLength getter to OperatorList, since the length is zero after flushing 
In the `RenderPageRequest` handler in `worker.js`, we attempt to print an `info` message containing the rendering time and the length of the operator list. The latter is currently broken (and has been for quite some time), since the `length` of an `OperatorList` is reset when flushing occurs.
This patch attempts to rectify this, by adding a getter which keeps track of the total length.

50ff2d4c2a Ignore operators that are known to be unsupported 
`operatorList.addOp` adds the arguments to the list which is then
passed as-is by postMessage to the main thread. But since we don't
parse these operations, they are raw PDF objects and may therefore
cause a serialization error.

This is a conservative patch, and only affects operators which are
known to be unsupported. We should ignore all unknown operators,
but I haven't really looked into the consequences of doing that.

This patch adjusts `get fingerprint` to also check that the `/ID` entry contains (non-empty) strings, to prevent more possible failures when loading corrupt PDF files (follow-up to PR 5602).

Note that I've not actually encountered such a PDF file in the wild. However given that `stringToBytes` will assert that the input is a string, and that we'll thus fail to load a document unless `get fingerprint` succeeds, making this more robust seems like a good idea to me.

29a1cdb6a6 Only choose a (3, 1) cmap table for TrueType fonts that have an encoding specified (issue 6410) 
For (1, 0) cmaps, we have two different codepaths depending on whether the font has/hasn't got an encoding. But with (3, 1) cmaps we don't have a good fallback when the encoding is missing, hence this patch changes `readCmapTable` to only choose a (3, 1) cmap table if the font is non-symbolic *and* an encoding exists. Without this, we'll not be able to successfully create a working glyph map for some TrueType fonts with (3, 1) cmap tables.

Fixes 6410.

b1d148a4aa Remove Parser_fetchIfRef since it's obsolete 
This code was added in PR 1214, but was made obsolete by PRs 1488/1493. Prior to the latter ones, `Dict_get` retured the raw objects. However, afterwards (and currently) `Dict_get` now resolves indirect objects, which makes `Parser_fetchIfRef` redundant.

*Potential risks with this patch:*
This patch passes all tests locally, but there's a *small* possibility that it could break some weird PDF files.
In the current code, wrapping `Dict_get` inside `Parser_fetchIfRef` will potentially mean two back-to-back call of `XRef_fetch`, if a reference points directly to another reference. I'm not sure if this can actually happen in practice, and I'd think that if that were the case we'd already have run into it elsewhere in the code-base, given that `Parser` is the only place where we try to "double" resolve references.

Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1200096.

The problematic font has a `format 2` cmap, which we've never supported properly. Prior to PR 2606, we were able to fallback to a working state, despite not having proper support for that cmap format.

Obviously the best/correct solution would be to implement actual support for more cmap formats[1]. However, I'm hoping that a simple patch will be OK for now, given that:
 - `format 2` cmaps seem to be quite rare in practice, since this has been broken for 2.5 years before anyone noticed.
 - Having a simple patch will make potential uplifts a lot easier.

This patch changes the font renderer to instead emit commands that are compiled
by the font loader. If, during compilation, we receive an EvalError, we instead
interpret them.

b0a8c0fa40 cmaps: Use cmap.forEach instead of Array.forEach 
CMaps may be sparse. Array.prototype.forEach is terribly slow in Chrome
(and also in Firefox) when the sparse array contains a key with a high
value. E.g.

    console.time('forEach sparse')
    var a = [];
    a[0xFFFFFF] = 1;
    a.forEach(function(){});
    console.timeEnd('forEach sparse');

    // Chrome: 2890ms
    // Firefox: 1345ms

Switching to CMap.prototype.forEach, which is optimized for such
scenarios fixes the problem.

I used the code from flag 0 (which works) to understand which is which. It is also important to understand that for flags 1,2 and 3, the stream is always assigned to the same coordinates and colors. What changes is which "old" coordinates and colors are assigned to what is "missing" in the stream. This is why for these flags, the code is identical except for the assignments in the first "row". (Same principle as in #6304). Note that this change will not improve the lamp_cairo.pdf file, only the two files mentioned in #6305.

55bc98a8b0 Rename PatternType to ShadingType to avoid confusion 
The current name is somewhat confusing, since the specification calls it `ShadingType`, see http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G7.4044105 and http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G7.3882826.

The real problem, however, is that there is actually another property called `PatternType`, which makes the current code very confusing, see http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G7.1850929.

Since `ShadingType` is only relevant for shading patterns (i.e. `PatternType === 2`), and *not* for tiling patterns (i.e `PatternType === 1`), this patch should help reduce confusion when reading the code.

4f920ad100 Refactor annotation code to use a factory 
Currently, `src/core/core.js` uses the `fromRef` method on an `Annotation` object to obtain the right annotation type object (such as `LinkAnnotation` or `TextAnnotation`). That method in turn uses a method `getConstructor` to find out which annotation type object must be returned.

Aside from the fact that there is currently a lot of code to achieve this, these methods should not be part of the base `Annotation` class at all. Creation of annotation object should be done by a factory (as also recommended by @yurydelendik at https://github.com/mozilla/pdf.js/pull/5218#issuecomment-52779659) that handles finding out the correct annotation type object and returning it. This patch implements this separation of concerns.

Doing this allows us to also simplify the code quite a bit and to make it more readable. Additionally, we are now able to get rid of the hardcoded array of supported annotation types. The factory takes care of checking the annotation types and falls back to returning the base annotation type (and issuing a warning, which the current code also does not do well) when an annotation type is unsupported.

I have manually tested this commit with 20 test PDFs with different annotation types, such as /Link, /Text, /Widget, /FileAttachment and /FreeText. All render identically before and after the patch, and unsupported annotation types are now properly indicated with a warning in the console.

e211c25f06 Improve robustness of stream parser (invalid length) 
When the parser finds a stream, it retrieves the Length from the stream
dictionary and advances the lexer to the offset as specified in Length.
If this Length is incorrect, the lexer could end up anywhere.

When the lexer gets in an invalid state, it could throw errors. For
example, in issue 6108, the lexer ends up inside the stream data. This
stream has the ASCIIHexDecode filter, so all characters are made up from
ASCII characters, and the lexer interprets it as a command token. Tokens
cannot be longer than 127 bytes, so eventually 128 bytes are consumed
and the lexer throws "Command token too long" error.

Another possible error is "Illegal character: 41" when the lexer happens
to end up at a ')' due to the length mismatch.

These problems are solved by catching lexer errors and recovering the
parser via the existing stream length detection branch.

fd29bb0c57 Subtract start offset for xrefs in recovery mode 
Xref offsets are relative to the start of the PDF data, not to the start
of the PDF file. This is clear if you look at the other code:

- In the XRef's readXRefTable and processXRefTable methods of XRef, the
  offset of a xref entry is set to the bytes as given by a PDF file.
  These values are always relative to the start of the PDF file (%PDF-).

- The XRef's readXRef method adds the start offset of the stream to
  Xref entry's offset: "stream.pos = startXRef + stream.start".
  Clearly, this line assumes that the entry offset excludes the start
  offset.

However, when the PDF is parsed in recovery mode, the xref table is
filled with entries whose offset is relative to the start of the stream
rather than the PDF file. This is incorrect, and the fix is to subtract
the start offset of the stream from the entry's byte offset.

The manually created PDF file serves as a regression test. It is a valid
PDF, except:
- The integer to point to the start of the xref table and the %%EOF
  trailer are missing. This will activate recovery mode in PDF.js
- Some junk was added before the start of the PDF file. This exposes the
  bad offset bug.

456ad438d8 Issue a warning instead of an error for long Names 
The PDF specification (cited below) specifies a maximum length of a name
in bytes as a minimal architectural limit. This means that PDF *writers*
should not create names that exceed 127 bytes.

It does not forbid PDF *readers* to accept such names though. These
names are only used internally to link PDF objects to other objects. For
these use cases, the lengths of the names do not really matter. Hence I
have changed the implementation to not treat long names as errors, but
warnings.

> (7.3.5) The length of a name shall be subject to an implementation
> limit; see Annex C.
>
> (Annex C.2) Table C.1 describes the minimum architectural limits that
> should be accommodated by conforming readers running on 32-bit
> machines. Because conforming readers may be subject to these limits,
> conforming writers producing PDF files should remain within them.
>
> (Table C.1) name 127 "Maximum length of a name, in bytes."

7df78f997e Slightly more efficient getDestination 
For named destinations that are contained in a `Dict`, as opposed to a `NameTree`, we currently iterate through the *entire* dictionary just to fetch *one* destination.
This code appears to simply have been copy-pasted from the `get destinations` method, but in its current form it's quite unnecessary/inefficient since can just get the required destination directly instead.
 2015-07-08 18:31:51 +02:00
Jonas Jenwald
940bedf75f Add a unit-test that attempts to fetch a non-existent named destination 
Doing this helped uncover an issue with the `getDestination` implementation.
Currently if a named destination doesn't exist, the method (in `obj.js`) may return `undefined` which leads to the promise being stuck in a pending state.
*Note:* returning `null` for this case is consistent with other methods, e.g. `getOutline` and `getAttachments`.

bc865b9e2d Ensure that we fetch all indirect objects (i.e. |Ref|s) in ColorSpace_parseToIR 
Recently I've landed a number patches which fixed issues with ColorSpaces. In most of these cases the cause of the failures were, either partially or entirely, related to the fact that we didn't resolve indirect objects (i.e. the code was missing `xref.fetchIfRef(...)`).

The purpose of this patch is to fix the few remaining cases where indirect objects *could* potentially cause failures.
Given that we have seen how this causes failures in practice, I thus think that it makes sense to try and avoid further issues, instead of waiting for users to file even more bugs for this part of the code-base.

a64536901a Increase the font weight used for non-embedded ArialBlack fonts 
Currently non-embedded ArialBlack fonts are not rendered bold enough, compared to e.g. Adobe Reader.
The issue is that we set the font weight to `bolder`, but since that is actually relative to the font weight of the parent, the result is that there's no practical difference from just using `bold`.

This patch attempts to address that, by explicitly setting the font weight to the maximum value instead (see https://developer.mozilla.org/en-US/docs/Web/CSS/font-weight).

*Note:* I expect one test "failure" in `issue5801`, which in this case is an improvement, since that PDF file uses ArialBlack.

Further down in that file, https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/hb-ot-shape-fallback.cc#216, the vertical position of glyphs is modified, which should thus explain why some glyphs end up in the wrong position in the PDF file.

f19a1db414 Create a IdentityToUnicodeMap in evaluator.js when toUnicode contains IdentityH/IdentityV 
Currently if a font contains a `toUnicode` entry, we always create a new `ToUnicodeMap` in evaluator.js. This is done even for `IdentityV/IdentityH`, despite to possibility to use the much more compact `IdentityToUnicodeMap` representation.
This patch refactors the `IdentityH/IdentityV` cases, to:
 - Avoid calling `IdentityCMap.getMap`, since this prevents allocating and iterating through an array with 65536 elements.

 - Ensure that the handling of `toUnicode` is actually correct in fonts.js.
We rely on `toUnicode instanceof IdentityToUnicodeMap` in a few places, and currently this does not work correctly for `IdentityH/IdentityV`.

979635138a Improves rendering performance of annotation layers. 
This change does the following:
 * Address TODO to remove getEmptyContainer helper.
 * Not set container bg-color. The old code is incorrect, causing it to
   not have any effect. It sets color to an array (item.color) rather
   css string. Also in most cases it would set it to black background
   which is incorrect.
 * only add border instructions when there is actually a border
 * reduce memory consumption by not creating new 3 element arrays for
   annotation colors. In fact according to spec, this would be incorrect,
   as the default should be "transparent" for an empty array. Adobe
   Reader interprets a missing color array as black however.

Note that only Link annotations were actually setting a border style and
color. While Text annotations might have calculated a border they did
not color it. This behaviour is now controlled by the boolean flag.

d8b905048b Add fallback for non-embedded "Century Gothic" CIDFontType2 font (issue 4722 and bug 879561) 
According to practical experiments, falling back to "Helvetica" when we encounter a non-embedded "[Century Gothic](http://en.wikipedia.org/wiki/Century_Gothic)" `CIDFontType2` font seems to work well.
(Also, the section on Wikipedia about "Printer ink usage" *might* provide some anecdotal evidence that Century Gothic is a fairly standard sans-serif font.)

Obviously this patch doesn't make "Century Gothic" fonts render perfectly, as is often the case with non-embedded fonts, but all the text is now legible in the referenced issues.

Fixes 4722.

(This may be overkill)
- Some documents we encountered have invalid xref ids, which were
always coming out as ‘0000000000000000’ - so we detect that and use the

96a77e9d6a Add basic support for non-embedded Wingdings fonts 
This is a tentative patch that adds *very* basic support for non-embedded Wingdings fonts (a Windows version of Dingbats), by falling back to the ZapfDingbats encoding. Obviously this approach will not work perfectly, but in my opinion it seems to work reasonably well in pratice.

Instead of this very simple patch, another option would be to try and include more complete glyph data for Wingdings, e.g. a Unicode map and glyph widths, similar to what was done for ZapfDingbats.
However there is, in my opinion, one important difference between Wingdings and ZapfDingbats: ZapfDingbats is part of the 14 standard fonts, which in previous versions of the PDF specification was assumed to be available in PDF readers. To improve compatibility with older files, it thus makes sense for us to include data for ZapfDingbats.
However Wingdings has never been a standard font in PDF files, hence PDF files using it *should* thus contain all the necessary font data.

Given the above, I thus believe that it should be OK to fall back to ZapfDingbats for now. If non-embedded Wingdings fonts turns out to be *a lot* more common, then we can revisit this later.

Fixes 4301 completely.
Fixes 4837 almost completely. With this patch the bullets are displayed correctly, but the arrows are not of the correct type.
Fixes `artofwar.pdf`, pages 14 and 15.

970c048d50 fixes caching of inline images during parsing. 
As described in #5444, the evaluator will perform identity checking of
paintImageMaskXObjects to decide if it can use
paintImageMaskXObjectRepeat instead of paintImageMaskXObjectGroup.

This can only ever work if the entry is a cache hit. However the
previous caching implementation was doing a lazy caching, which would
only consider a image cache worthy if it is repeated.
Only then the repeated instance would be cached.
As a result of this the sequence of identical images A1 A2 A3 A4 would
be seen as A1 A2 A2 A2 by the evaluator, which prevents using the
"repeat" optimization. Also only the last encountered image is cached,
so A1 B1 A2 B2, would stay A1 B1 A2 B2.

The new implementation drops the "lazy" init of the cache. The threshold
for enabling an image to be cached is rather small, so the potential waste
in storage and adler32 calculation is rather low. It also caches any
eligible image by its adler32.

The two example from above would now be A1 A1 A1 A1 and A1 B1 A1 B1
which not only saves temporary storage, but also prevents computing
identical masks over and over again (which is the main performance impact
of #2618)

ca027ebfdb Fix the exception propagation when rejecting workerReadyCapability 
Currently when an exception is thrown, we try to reject `workerReadyCapability` with multiple arguments in src/core/api.js. This obviously doesn't work, hence this patch changes that to instead reject with the exception object as is.
In src/core/worker.js the exception is currently (unncessarily) wrapped in an object, so this patch also simplifies that to directly send the exception object instead.

The scanned, black-and-white document at

the critical GRAYSCALE_1BPP optimization because the optimization is
skipped if `needsDecode` is set.

This change addresses that, and reduces both rendering time and memory
usage for that document by almost 10x.

For the document in #2504, 11% of the ops are `setGState` with a
`gStateObj` that is an empty array, which is a no-op. This is possible
because we ignore various setGState keys (OP, OPM, BG, etc).

This change prevents these ops from being inserted into the operator
list.

ffae848f4e Reduce ASCII checks in makeInlineImage(). 
makeInlineImage() has a "are the next five chars ASCII?" check which is
run after an "EI" sequence has been found. This check involves the
creation of a new object because peekBytes() calls subarray().

Unfortunately, the check is currently run on whitespace chars even when
an "EI" sequence has not yet been found, i.e. when it's not needed. For
the PDF in #2618, there are over 820,000 such checks.

This change reworks the relevant loop so that the check is only done
once an "EI" sequence has been seen. This reduces the number of checks
to 157,000, and speeds up rendering by somewhere between 2% and 7% (the
measurements are noisy).

61e6b576d4 Avoid an allocation in readCharCode(). 
readCharCode() returns two values, and currently allocates a length-2

passed-in object which can be reused.

in Mozilla bug 992125 by 4.2%.

7cbd057deb Avoid unnecessary array allocations in EvaluatorPreprocessor_read(). 
EvaluatorPreprocessor_read() is called in two cases. For the normal
layer, the args array it produces is used beyond the bounds of the loop
in which EvaluatorPreprocessor_read() is called.

But for the text layer, the args array is used in a very short-term
fashion. This change reworks things so that a single array is repeatedly
used for the text layer. This reduces total JS allocations for the
Spoorkaart map by 11%, and has similar effects on many other PDFs.

After PR 4982, the rendering of the first two pages of http://www.openmagazin.cz/pdf/2011/openMagazin-2011-04.pdf (from issue 215) no longer completes.

The issue is that we cannot have `args === null` in `PartialEvaluator_buildPath`, but *must* use an empty array instead.

In this patch I've also moved the `argsLength` variable definition in `EvaluatorPreprocessor_read`, to make sure that it's always defined.

51055e5836 Make IdentityCMaps more compact. 
IdentityCMap uses an array to represent a 16-bit unsigned identity
function. This is very space-inefficient, and some files cause multiple
IdentityCMaps to be instantiated (e.g. the one from #4580 has 74).

This patch make the representation implicit.

adf58ed687 Represent cid chars using integers, not strings. 
cid chars are 16-bit unsigned integers. Currently we convert them to
single-char strings when inserting them into the CMap, and then convert
them back to integers when extracting them from the CMap. This patch
changes CMap so that cid chars stay in integer format throughout, saving
both time and space.

When loading the PDF from issue #4580, this change reduces peak RSS from
~600 to ~370 MiB. It also improves overall speed on that PDF by ~26%,
going from 724 ms to 533 ms.

c3c72948b9 Stop including cidmaps.js 
In b5b94a4af3, i.e. PR #4259, we stopped using cidmaps.js. Despite that, it's still included when PDF.js is built. At almost 0.5 MB (and approx. 7000 lines), this is currently the single largest file in the codebase.
Including such a large file in the builds, when it is not actually used, seems extremely wasteful; hence this patch.

dd2adf6200 Fixes mesh fill pattern with optional matrix (#5020) 
In the referenced issue, there is a PDF which uses a fill pattern which does not
have a matrix defined. This causes singularValueDecompose2dScale to fail with
undefined property error when accessing elements of that matrix.

This fix will only use the matrix when it is defined. The output for the PDF in
question now looks identical to chrome and preview with respect to the gradient
fill pattern.

a483c80fc3 Make QueueOptimizer easier to read. 
QueueOptimizer is really hard to read. Enough so that it's blocking my
efforts to streamline the representation used for operator lists.

This patch improves its readability in the following ways.

- More descriptive variable names make the sequence checking much clearer,
  as do additional comments.

- The addState() functions now return the index of the first op past the
  sequence, instead of setting context.currentOperation to the last op of
  the sequence.

- The loop in optimize() is clearer.

- The array modification in the fourth addState() function is much clearer
  -- we're just removing trios of ops.

- All four |addState| functions are now more consistent with each other.

I used some debug printfs to find documents where these optimizations are
used and then checked that the number of optimized ops was the same before
and after my changes.

db866945b7 Improve how DecodeStream handles empty buffers. 
DecodeStream currently initializes its |buffer| field to |null|, which
is reasonable, because lots of DecodeStreams never need to instantiate a
buffer. But this requires various special cases in the code.

This patch change it so DecodeStreamClosure has a single empty
Uint8Array which gets shared between all buffers upon initialization.
This avoids the special cases.

DecodeStream.prototype.ensureBuffer() is really hot, and this removes a
test from the fast path. For one 226 page scanned document this sped up
rendering by about 2%.

bce7601480 Build up textChunk.str more efficiently. 
PartialEvaluator.getTextContent() builds up textChunk strings 1 char at a time,
creating many 100s of 1000s of intermediate strings along the way. This patch
make it instead push chars to an array and then join them at the end, as we
have done in numerous other places.

4428cebdbc Add ChunkedStream.ensureByte(). 
This new function is much faster than ensureRange(pos, pos+1), which is a very
common case.

This speeds up the rendering of some test cases (including the Tracemonkey
paper) by 4--5%.

22a0e7fe65 Optimization for FlateStream_getCode, making more pdfs parsable. 
This commit cleans up the FlateStream_getCode method, and removes a few error
conditions.
Previously it would fail if the codeSize is less than maxLen if end of stream
is reached. However in the document linked below there is a sub-stream
(the one starting at pos 337) which has maxLen set to 11, but actually
contains only 10. After breaking the sanity check still applies, and in this
case passes validating codeSize(10)==codeLen(10).

0a42edf82f Optimize JPG.js receiveAndExtend for 1 bit case. 
Profiling showed that receiveAndExtend is frequently called with the length of
one bit. This happens for example in decodeBaseline.
For a single bit, the loop and shift in receive, as well as the shifts in
receiveAndExtend are overhead.
This shortcut manually calculates the shifts by either returning 1 or -1 from
receiveAndExtend by reading the bit and deciding on the return value.
While it comes with an overhead for each non-one length, the speedup is at about
10% in the hot parse/decode path.

e7fe45a5c4 Refactor jpg.js and include forceRGBoutput, correct style of image.js 
This refactors getData to be more readable and extracts all the color
conversion algorithms to their own functions. The resulting code was then
cleaned up.
This also introduces a flag `forceRGBoutput` to getData, that allows to always
get the data as a `width * height * 3` bytes long RGB buffer

The function `assertWllFormed` was doing nothing different than `assert` which is
available in the same namespace. Removing it will lighten the filesize - albeit

79f34b183c Treat fonts with the same font descriptor, encoding and unicode map as aliases 
Different fonts can point to the same font descriptor
(see https://github.com/mozilla/pdf.js/issues/4339 for details). With this
commit such fonts are treated as aliases if they have also the same encoding
and the same toUnicode map. The according info is stored on the font descriptor.
This change must also ensure that aliases use always the same font name
because translated fonts can get cleared depending on the CLEANUP_TIMEOUT setting.

292b96a0bf Make fnArray always be a plain array. 
This makes the code much simpler, and the extra memory use is tiny -- a vanilla
1000 element array is only 4000 bytes larger than a Uint32Array of the same
size.

6a75e45309 Allocate fewer objects when parsing 2 and 4 byte chunks. 
This is achieved by adding getBytes2() and getBytes4() to streams, and by
changing int16() and int32() to take multiple scalar args instead of an array
arg.

0866ad5bff Add a cache for glyphs. 
This reduces memory consumption for text heavy documents. I tested five
documents and saw hit rates ranging from 97.4% to 99.8% (most of the misses are
due to |width| varying even when |fontChar| matches). On two of those documents
I saw improvements of 40 and 50 MiB.

The patch also introduces the Glyph constructor, and renames the |unicodeChars|
local variable as |unicode| for consistency with the corresponding Glyph
property.

b3024db677 Estimate the size of decoded streams in advance. 
When decoding a stream, the decode buffer is often grown multiple times, its
byte size increasing like so: 512, 1024, 2048, etc. This patch estimates the
minimum size in advance (using the length of the encoded stream), often
allowing the smaller sizes to be skipped. It also renames numerous |length|
variables as |maybeLength| to make it clear that they can be |null|.

I measured this change on eight documents. This change reduces the cumulative
size of decode buffer allocations by 0--32%, with 10--20% being typical. This
reduces peak RSS by 10 or 20 MiB for several of them.

d0253c8291 Don't get bytes eagerly when creating {Jpeg,Jpx,Jbig2}Stream objects. 
This avoids lots of unnecessary work when such streams are referred to via
fetch(), and so their bytes aren't subsequently read. This is a large
performance win on some files.

f12d588258 Add an ensureRange() call to ChunkedStream_makeSubStream(). 
By checking if the data is all present before making a substream, we avoid
cases where we parse part of a stream and then throw a MissingDataException
part-way through, which forces us to later re-read the stream -- possibly
multiple times. This is a sizeable performance win for some cases when file
loading is slow (e.g. over the web).

076b3433b4 Improved annotations' display/behavior. 
Added an "InteractiveAnnotation" class to homogenize the annotations' structure (highlighting) and user interactions (for now, used for text and link annotations).

Text annotations:
The appearance (AP) has priority over the icon (Name).
The popup extends horizontally (up to a limit) as well as vertically.
Reduced the title's font size.
The annotation's color (C) is used to color the popup's background.
On top of the mouseover show/hide behavior, a click on the icon will lock the annotation open (for mobile purposes). It can be closed with another click on either the icon or the popup.

An annotation printing is conditioned by its "print" bit
Unsupported annotations are not displayed at all.

4a66eccedc Rewrite Lexer_getNumber. 
Now, it computes the numbers with only basic arithmetic operations, without first creating a string and then calling parseFloat.
The new function doesn't behave exactly the same as the old one.
In particular, the old behaviour was that when there was a number immediatly followed by an 'E', the 'E' was consumed. Now it's not. It allows for "glued" numbers and operators.
Also, the new function is faster and consumes less memory.

<< /S /URI /URI (http://127.0.0.1/v/index.php/File:Logo.png >>

The URL should be wrapped in parentheses, but sometimes it isn't.
Consequently, the value is interpreted as a Name (because of the leading "/"),
and the resulting object is `{name: "v/index.php/File:Logo.png" }`. Obviously,
this is not a string, so `url.indexOf` throws an error here.

Rob Wu
43847d7ff8 Set eof to true at the end of a FlateStream 
At the initialization of `Lexer_getObj` (in `parser.js`), there's a loop
that skips whitespace and breaks out whenever EOF is encountered.
(https://github.com/mozilla/pdf.js/blob/88ec2bd1a/src/core/parser.js#L586-L599)

Whenever the current character is not a whitespace character,
`ch = this.nextChar();` is used to find the next character
(using `return this.currentChar = this.stream.getByte())`).

The aforementioned `getByte` method retrieves the next byte using
(https://github.com/mozilla/pdf.js/blob/88ec2bd1a/src/core/stream.js#L122-L128)

      var pos = this.pos;
      while (this.bufferLength <= pos) {
        if (this.eof)
          return -1;
        this.readBlock();
      }
      return this.buffer[this.pos++];

This piece of code relies on this.eof to detect whether the last character
has been read. When the stream is a `FlateStream`, and the end of the stream
has been reached, then **`this.eof` is not set to `true`**, because this check
is done inside a loop that does not occur when the read block size is zero:
(https://github.com/mozilla/pdf.js/blob/88ec2bd1ac/src/core/stream.js#L511-L517)

      for (var n = bufferLength; n < end; ++n) {
        if (typeof (b = bytes[bytesPos++]) == 'undefined') {
          this.eof = true;
          break;
        }
        buffer[n] = b;
      }

This commit fixes the issue by setting this.eof to true whenever the loop is not
going to run (i.e. when bufferLength === end, i.e. blockLen === 0).

3ddb1720d9 Fix bug in api.js whereby fake workers didn't load the worker code 
PDFJS does not work on Windows Safari, due to the lack of support for workers passing typed arrays. At some point, the code to set up the fake worker so that things work on Safari seems to have become broken and nobody noticed - it was just calling setupFakeWorker() without actually calling loadFakeWorkerFiles(). With this patch, the PDFJS works again on Windows Safari.

cc04cf5d1f Configurable IMAGE_DIR for annotations 
The Chrome extension activates PDF.js by inserting the script tags
in a document whose URL and location origin is identical to the PDF
file.
Because of this, the path './images/' was resolved relatively to the
location of the PDF file instead of the extension.

To fix this, the IMAGE_DIR constant is moved outside the local scope,
to allow extensions/chrome/insertviewer.js to override the value.

Originally, the IMAGE_DIR variable was a global variable, but commit
f8f4b3f45d moved the global variable
to the local scope, causing the extension to malfunction.

Impact: low, the only consequence is that some rarely used images
were not visible.

Trivial test:
At the center of page 2, the annotation icon
(images/annotation-comment.svg) should be visible:
