2015-12-06Merge to XFA: fix 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.

2015-11-20Merge to XFA: Change |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.

2015-11-12Merge to XFA: Clear 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 TBR=tsepez@chromium.org Review URL: https://codereview.chromium.org/1406943005 .
