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 .

2015-11-11Merge to XFA: 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.

2015-09-29Merge to XFA: Fix blank page issue caused by too strict correction on bpcJun Fang
For bit per component (bpc), PDF spec mentions that a RunLengthDecode or DCTDecode filter shall always deliver 8-bit samples. However, some PDF files don't follow this rule. We can find that filter is RunLengthDecode but bpc is 1 in the provided test file. In this case, pdfium will correct bpc to 8 but the actual bpc is 1. It causes a failure because the data is much more than the expected. To handle this case, pdfium doesn't correct bpc to 8 when the original bpc is 1.

Pdfium swallows 'fi' or 'ff' in some tested files because it doesn't load the embedded font file correctly. The root cause is that there is incorrect keyword like 'ngendstream' in the stream of the embedded font file.
