2016-11-14Make CPDF_PageContentGenerator methods take object numberstsepez
This patch fixes a possibility that an owned CPDF_Stream is handed to the indirect object holder inside RealizeResource(). Its arguments are changed to take an object number, as is done elsewhere in the code, to suggest that only indirect objects are acceptable. BUG=660756 Review-Url: https://codereview.chromium.org/2489423002
2016-11-14Properly release caches in CPDF_DocRenderDatanpm
Currently, only RemoveRef() is being called when releasing. The problem is that when the object is no longer being used, the map is not updated accordingly. In the pdf in the bug below, the pointer of a font used in the second page coincides with the pointer of a font in the first page (that was released). So the cached values for the font in the first page are used, resulting in incorrect rendering. BUG=pdfium:629 Review-Url: https://codereview.chromium.org/2501053002
2016-11-11Relax colorspace checks in CPDF_DIBSource::CreateDecoder().chromium/2917thestig
Previously the log just made sure the colorspace and the image have exact matches for the number of colorspace components. Now, for some colorspace types, check the type and make sure the number of components meets or exceeds what is required by the spec. Also do some refactoring.

2016-11-09Do not load main cross ref table for first page in linearized pdf.art-snake
For the first page in linearized PDFs, it is not necessary to load the main xref table, because it have separate special xref table in the file header. This decreasing the time to show first page in PDF plugin. Review-Url: https://codereview.chromium.org/2483633002
2016-11-09Add early returns in CJBig2_TRDProc::decode_Arith when decode fails.npm
None of the decodes in the method are currently being checked. This is causing pdfium to take a long time rendering corrupted files. Thus, I added a couple of early returns to help prevent this from happening. BUG=450971 Review-Url: https://codereview.chromium.org/2493633002

2016-11-04Traverse PDF page tree only once in CPDF_Document Try 3npm
Now, we do not start traversal from where we were at, but from the top. This makes the code less prone to bugs, as now there is no need to call methods to recursively fix things. This will save a lot of time when the trees are rather flat, as in the PDF file in the bug. It can still be slow, for instance if we have a chain of page nodes, and the last in the chain contains all of the pages (this is artificial). Try 2 at https://codereview.chromium.org/2442403002/ Also added test where Try 2 would have failed.
