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 .

2015-12-08Fix 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 .

2015-11-20Change |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.

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 .

2015-11-16Reland "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 .

2015-11-12Clear 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
