Fabian Lange	ceffeab1de	Use 3 param method for converting r,g,b into css string. ... This avoids creation of temporary arrays to pass them into the util method. Also using "arguments" is more expensive then passing in 3 parameters.	2014-12-05 19:25:02 +01:00

Fabian Lange	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)	2014-10-28 15:39:41 +01:00

Fabian Lange	b2d7c285c0	For JPX decoding only read next packet after checking for byte aligning. ... This patch makes the image from #5349 appear correctly, the artefacts for the last packet are fixed in #5426.

Jonas Jenwald	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.	2014-09-08 22:20:41 +02:00

The scanned, black-and-white document at https://bugzilla.mozilla.org/show_bug.cgi?id=835380 doesn't benefit from the critical GRAYSCALE_1BPP optimization because the optimization is skipped if `needsDecode` is set.

Nicholas Nethercote	9674abc542	Ignore setGState no-ops. ... 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.	2014-08-14 20:46:28 -07:00
Nicholas Nethercote	bcc31b666f	Right-size the array in getSampleArray(). ... This allows the JS engine to do a better job of allocating the right number of elements for the array, avoiding some resizings.

Nicholas Nethercote	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).	2014-08-14 16:20:58 -07:00

Nicholas Nethercote	61e6b576d4	Avoid an allocation in readCharCode(). ... readCharCode() returns two values, and currently allocates a length-2 array on every call to do so. This change makes it instead us a passed-in object which can be reused. This tiny change reduces the total JS allocations done for the document in Mozilla bug 992125 by 4.2%.	2014-08-12 16:12:58 -07:00
Nicholas Nethercote	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.	2014-08-11 16:57:40 -07:00

Nicholas Nethercote	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.	2014-08-01 02:35:17 -07:00

Nicholas Nethercote	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.	2014-07-03 19:16:31 -07:00
Nicholas Nethercote	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%.	2014-07-02 18:53:21 -07:00

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.	2014-06-05 12:24:53 +02:00

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.	2014-04-08 20:45:21 +02:00
