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).
In Chromium extensions, the viewer's URL looks like this:
chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/http://example.com/file.pdf
Furthermore, the PDF Viewer itself can also add something to the reference fragment:
chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/http://example.com/file.pdf#page=2
Consequently, it is difficult to copy a clean URL (e.g. for sharing over mail)
without having to tidy-up the URL manually.
This commit solves this issue by adding a button to the omnibox,
which shows the clean PDF URL on click.
Line 56-58: "Gegen den Uhrzeigersinn" is shorter and more common than "Entgegen dem Uhrzeigersinn" (http://de.wikipedia.org/wiki/Drehrichtung)
Line 60-63: "Hand-Werkzeug" is also used in Acrobat
Line 124,133,..: "PDF" is not a noun. Acrobat, Wikipedia use "PDF-Datei" (="PDF file") instead of "PDF".
The English translation sounds just as bad: "An error occurred while loading the PDF.", "The PDF is not fully loaded for printing."
