2015-10-09Merge to XFA: Sanitize CJBig2_SymbolDict's memory usage.Lei Zhang
- Use std::vector<JBig2ArithCtx> instead of storing pointers to arrays. - Make CJBig2_SymbolDict's members private with accessors. - Use std::vector<JBig2ArithCtx> in related places. - Steal Chromium's vector_as_array() and use it as an adaptor as needed.

2015-10-09Merge to XFA: Fix heap-buffer-overflow in color_sycc_to_rgbJun Fang
It's a bug existing in the conversion from YUV420 to RGB. For YUV 420 format, four pixels have 4 Y but only one U and one V. In some cases, there are odd columns or lines in some images. The pixels on last line or column may have Y but no U or V data. For this case, We shall extend U or V using the data on previous column or line.

2015-10-08Merge to XFA: Various changes to JBig2 cache:Lei Zhang

2015-10-08Merge to XFA: Relax the check on 0 length streams.Lei Zhang
CPDF_SyntaxParser::ReadStream() originally created stream objects when the length is 0. Commit 2526930 tightened the constraint and returned NULL. This has some adverse affects, as seen in Chromium's print preview of PDFs. Instead, relax the constraint a little so when the length is 0, return a CPDF_Stream with NULL data and size 0.

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. Pdfium tries to find another correct keyword but uses wrong offset rather than accumulated offset. BUG=524043 TBR=jun_fang@foxitsoftware.com Review URL: https://codereview.chromium.org/1307353005 .
