2015-12-10Remove CFX_AffineMatrix/CPDF_MatrixTom Sepez
These are synonyms for CFX_Matrix. Nothing but sed and manual deletion of 2 #defines in fpdf_parser.h and fx_coordinates.h R=thestig@chromium.org Review URL: https://codereview.chromium.org/1513363002 .

2015-12-09Get rid of most uses of CFX_PtrArray.Tom Sepez
I didn't go whole hog and replace these with std::vector, but in the mean time, it is silly to cast a typedef for a template instantiated against void* when we can just instantiate the template against the actual type. The ones that remain are actual heterogeneous arrays with wacky casting. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1518593002 .
2015-12-08Revert "Merge to master: Take Jun's UTF16LE patches."chromium/2587chromium/2586Oliver Chang

2015-12-08Fix rendering with built-in CID fontsJun Fang
The root cause is that FXFONT_SUBST_EXACT is wrongly set even no any subset font was found. It causes m_bCIDIsGID to be wrongly set as TRUE in CPDF_CIDFont::_Load(). BUG=534945 R=thestig@chromium.org, tsepez@chromium.org Review URL: https://codereview.chromium.org/1502083002 .
2015-12-06fix for stream object readingWei Li
Loosen a check for earlier version of PDF files. When the bytes with specified length are followed by 'endstream' keyword, even if there is no EOL marker before the keyword, it signals the end of stream. BUG=551258 R=jun_fang@foxitsoftware.com, tsepez@chromium.org Review URL: https://codereview.chromium.org/1499433002 .

RebuildCrossRef function returns false when we can not find file trailer or any indirect object. This serves as a basic file format checking. BUG=pdfium:215 R=jun_fang@foxitsoftware.com Review URL: https://codereview.chromium.org/1476163002 .

2015-11-24Re-virtualize CFX_UnicodeEncoding.Tom Sepez
It's not required on master, but it costs very little and makes XFA line up more closely. Also make InitFTLibrary() public for the same reasons. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1475643003 .
2015-11-24Fix a NULL pointer crash in the CJBig2_Image copy constructor.Lei Zhang
Also change the copy ctor to take a const ref. BUG=560520 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1472113002 .
2015-11-20Change |CCodec_ScanlineDecoder::m_Pitch| to FX_DWORDOliver Chang
This matches the type of the corresponding |CFX_DIBSource::m_Pitch|, where integer overflow is checked for FX_DWORD. This change is propagated to many other places. Also, check for integer overflow in |CCodec_RLScanlineDecoder::Create| during the calculation of |m_Pitch| since it aligns to 4 bytes while overflow was was previously checked without this alignment. R=tsepez@chromium.org, thestig@chromium.org BUG=555784 Review URL: https://codereview.chromium.org/1460033002 .

2015-11-19Add more overrides.Lei Zhang
Using Chromium's clang + build options, there's more override warnings. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1453643002 .
2015-11-19Add a missing setjmp() to CCodec_JpegDecoder::v_GetNextLine().Oliver Chang
If jpeg_read_scanlines() ends up calling the error callback, we longjmp into some undefined state. BUG=558840 R=thestig@chromium.org, tsepez@chromium.org Review URL: https://codereview.chromium.org/1463563003 .
2015-11-19Remove CFX_Matrix::Reset()Tom Sepez
It's unused on master, and on XFA, directly calling SetIdentity() is clearer to the reader anyways. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1459243002 .
2015-11-19Make core in master match XFA.Tom Sepez
This weeks version, mostly whitespace. TBR=thestig@chromium.org Review URL: https://codereview.chromium.org/1466503002 .

2015-11-17Make CPDF_InterForm::AddStandardFont take a non-const document pointer.Lei Zhang
Instead of taking a const pointer, and then casting away the const-ness. Also remove similar, but dead CPDF_InterForm methods. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1456763003 .
2015-11-17Add more fxcrt string sanity tests.Lei Zhang
Sadly I've gotten these to fail with Chromium debug builds. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1447163004 .
2015-11-16Reland "Cleanup some numeric code.""chromium/2567Dan Sinclair
This reverts commit 0569ab0b11b723d9bca4ddd642b0cf8828c4bdd1. This changes the various comparisons of char >= '0' && char <= '9' and char < '0' || char > '9' to use std::isdigit checks. It also cleans up a handful of hex to digit conversions to call one common method. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1449873003 .
2015-11-12Remove relative includes.Lei Zhang

2015-11-12Clear decoders after the image decoder in the /Filter array.Oliver Chang
During decoding, when an image decoder is encountered, any subsequent decoders are ignored, but remain in the array. However, later on CPDF_DIBSource::ValidateDictParam expects the image decoder to be the last in the array, causing issues. A check is also added in CPDF_DIBSource::GetScanline to ensure that the calculated pitch value is <= the (4-aligned) pitch value in the cached bitmap to prevent future issues. Also cleans up some NULL usages. BUG=552046 R=jun_fang@foxitsoftware.com, tsepez@chromium.org Review URL: https://codereview.chromium.org/1406943005 .
2015-11-11Fix / simplify CFX_FolderFontInfo::GetFontData() behavior.Lei Zhang
The GetFontData() behavior in FPDF_SYSFONTINFO seems reasonable. Also do some code cleanup. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1425023003 .
2015-11-11(Reland) Fix extraction of colour components in ↵Oliver Chang
CPDF_DIBSource::DownSampleScanline32Bit Previously, if |m_bpc| was < 8 (e.g. 4), this function may still try to access the source components as if |m_bpc| == 8. Even when it fell into the codepath that tried to do the right thing in this case, it was wrong.
