Jonas Jenwald	4ce5e520fb	Add different code-paths to `{CMap, ToUnicodeMap}.charCodeOf` depending on length, since `Array.prototype.indexOf` can be extremely inefficient for very large arrays (issue 8372) Fixes 8372.	8 years ago
Jonas Jenwald	afc74b0178	Enable the `object-shorthand` ESLint rule in `src/shared` Please see http://eslint.org/docs/rules/object-shorthand. For the most part, these changes are of the search-and-replace kind, and the previously enabled `no-undef` rule should complement the tests in helping ensure that no stupid errors crept into to the patch.	8 years ago
Jonas Jenwald	437104969d	Improve the error handling when loading of built-in CMap files fail (PR 8064 follow-up) I happened to notice that the error handling wasn't that great, which I missed previously since there were no unit-tests for failure to load built-in CMap files. Hence this patch, which improves the error handling and adds tests.	8 years ago
Jonas Jenwald	769c1450b7	[api-minor] Refactor fetching of built-in CMaps to utilize a factory on the `display` side instead, to allow users of the API to provide a custom CMap loading factory (e.g. for use with Node.js) Currently the built-in CMap files are loaded in `src/core/cmap.js` using `XMLHttpRequest` directly. For some environments that might be a problem, hence this patch refactors that to instead use a factory to load built-in CMaps on the main thread and message the data to the worker thread. This is inspired by other recent work, e.g. the addition of the `CanvasFactory`, and to a large extent on the IRC discussion starting at http://logs.glob.uno/?c=mozilla%23pdfjs&s=12+Oct+2016&e=12+Oct+2016#c53010.	8 years ago
Jonas Jenwald	50c2856097	Move `EOF`/`isEOF` from core/parser.js to core/primitives.js Given the nature of `EOF` and `isEOF`, it seems to me that they really ought to be placed in `core/primitives.js` instead. In general, it doesn't seem great to have to depend on the entire `core/parser.js` file for such simple primitives/helper functions. In particular, while `core/ps_parser.js` is completely separate from `core/parser.js` with regards to its function, it still depends on the latter for just one primitive. Note that compared to e.g. PR 7389, this will not reduce the number of dependencies for `core/ps_parser`, however the new dependency IMHO makes more sense.	8 years ago
Jonas Jenwald	90d19de935	Catch errors and continue parsing in `parseCMap` (issue 7492) After PR 7039, the PDF file in issue 7492 no longer renders at all, but note that text selection wasn't working correctly previously. The problem with the PDF file in issue 7492 is that the `cMap`, in the `toUnicode` entry in the font, contains an invalid name: ``` /CMapName /-usr-share-fonts-truetype-Panton-Panton Family-Fontfabric - Panton.otf,000-UTF16 def ``` When we parse that line, things obviously break because there are spaces present in the wrong places. To avoid that issue, the patch simply lets `parseCMap` continue when errors are encountered, to try and recover usable data. Note that by not aborting immediatly when an error is encountered, we are also able to fix the text selection. Obviously, it could be argued that we should just immediatly reject a corrupt `cMap`. But given that they usually are correct, it seems that trying to recover as much data as possible from corrupt one can only be a good thing for both glyph mapping and text selection. Fixes 7492.	9 years ago

Jonas Jenwald	8d831449ab	Right-size the `map` array in PartialEvaluator_readToUnicode We can avoid a lot of intermediate resizings, by directly allocating the required number of elements for the `map` array.	10 years ago

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%.	11 years ago
Yury Delendik	682b93ac9e	Fixes lint errors	11 years ago
Nicholas Nethercote	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. When loading the PDF from issue #4580, this change reduces peak RSS from ~370 to ~280 MiB. It also improves overall speed on that PDF by ~30%, going from 522 ms to 366 ms.	11 years ago
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.	11 years ago
Nicholas Nethercote	28687bca75	Optimize CMap.prototype.forEach(). This change avoids the element stringification caused by for..in for the vast majority of CMaps. When loading the PDF from issue #4580, this change reduces peak RSS from ~650 to ~600 MiB, and improves overall speed by ~20%, from 902 ms to 713 ms. Other CMap-heavy documents will also see improvements.	11 years ago
Nicholas Nethercote	b86daed29d	Make CMap.map quasi-private. This makes it easier for the representation to be improved.	11 years ago
Nicholas Nethercote	501446ccc4	Optimize common cases in hexToStr(). This avoids the creation of over two million array objects when viewing http://www.dynacw.co.jp/Portals/3/fontsamplepdf/sample_4942546800828.pdf, and reduces load time from 76 to 73 ms.	11 years ago
