2016-08-24Move parser out of IndirectObjectHolderdsinclair
This Cl moves the parser out of the indirect object holder and into the CPDF_Document where it is used. Review-Url: https://codereview.chromium.org/2277433003

2016-08-23Fix stack overflow in object Clone() functionsweili
For some complex objects such as CPDF_Dictionary, CPDF_Array, CPDF_Stream, and CPDF_Reference, Clone() could be executed with infinite recursion to cause the stack overflow. Fix this by checking already cloned objects to avoid recursion. BUG=pdfium:513 Review-Url: https://codereview.chromium.org/2250533002
2016-08-23Make indirect object holder private.dsinclair
This CL moves the m_IndirectObjs map to be private to the IndirectObjectHolder. Various bits of code have been updated to use the accessors to the map. This CL fixes the issue with the last time this landed by removing the objnum check from GetIndirectObject() which appears to have caused the crashes.

2016-08-23IndirectObjectHolder API updatesdsinclair
This Cl updates the names of the methods in the indirect object holder to better reflect their usage. The m_LastObjNum is made private and a setter added. Review-Url: https://codereview.chromium.org/2275593002

2016-08-19Move CFX_FaceCache to its own filenpm
Moved ScopedFontTransform from fx_ge_text namespace to fx_font Moved some arrays used by both CFX_Font and CFX_FaceCache from fx_ge_text to inside CFX_Font class Review-Url: https://codereview.chromium.org/2263623002
2016-08-19Avoid signed overflow in CPDF_ToUnicodeMap::StringToCode()tsepez
It was intended to be unsigned in the first place, and we're perfectly happy with the overflow as long as it is no longer undefined behaviour. BUG=638489 Review-Url: https://codereview.chromium.org/2258053003

2016-08-17Move parser pointer to CPDF_Documentdsinclair
The CPDF_IndirectObjectHolder has two subclasses, CPDF_Document and CFDF_Document. The CPDF document requires the parser and the CFDF document does not. This cl moves the parser pointer up to CPDF_Document. Review-Url: https://codereview.chromium.org/2253723002

2016-08-16Rename async to linearized when parsingdsinclair
The parser and document refer to async loading and parsing. The code isn't actually async but loading a linearized PDF. This Cl renames the methods to clarify what the code is doing. The LoadDoc() and LoadLinearizedDoc() methods have been refactored to share a common LoadDocInternal() method. Review-Url: https://codereview.chromium.org/2250163002

2016-08-15add native draw bitmap with alpha maskcaryclark
PDFs draw bitmaps with alpha by supplying an image alpha mask along side the image color data. The alpha mask may not be the same scale as the image data. Skia doesn't have a direct mapping for this draw call, but can come close by using the internal SkCompositeShader class. This scales the alpha mask to match the size of the image data, then puts both in the composite shader to draw. There are more things to do: - Allow Alpha8 or Gray8 to draw scaled to a matching device (blit doesn't work today) Temporary code marked with a TODO implements this functionality. - Refactor PDFium to allow SkComposeShader's components to take a matrix. The latter goal will defer drawing so that PDFium doesn't resize the mask, discarding resolution, before Skia has a chance to record it. Additionally fix drawing text with a negative font size.

2016-08-12Avoid an undefined shift in ReadPageHintTable().thestig
Even 39 bits is very generous for the number of bits needed to represent the greatest number of shared object references. BUG=637119 Review-Url: https://codereview.chromium.org/2242723002
2016-08-11Relax a check in CPDF_HintTables.thestig
CPDF_HintTables::ReadSharedObjHintTable() unnecessarily constraints a FX_FILESIZE value to an int32_t. Relax this check, since the result will be stored in |m_szSharedObjOffsetArray| which is of FX_FILESIZE. Bad values in |m_szSharedObjOffsetArray| will still cause hint table loading to eventually fail. BUG=635565 Review-Url: https://codereview.chromium.org/2230883003

2016-08-10Move CFX_RenderDevice, CFX_FxgeDevice, and CFX_GraphStateData into their own ↵npm
files. This is the third CL to separate fx_ge into classes, one per file. All fx_ge.h includes had to be replaced with new includes The method definitions for CFX_FxgeDevice were not moved to a single file. These methods are defined in two folders different from fxge/ge, so they were left untouched for now. Review-Url: https://codereview.chromium.org/2223213002

2016-08-08Move CFX_ClipRgn and CFX_PathData into their own files.npm
This is the second CL in an attempt to split up the classes in fxge/include/fx_ge.h into their own files. CFX_ClipRgn is moved to core/fxge/ge because it is only used in core/fxge. The header for CFX_PathData is left in core/fxge/include since it is used elsewhere. Review-Url: https://codereview.chromium.org/2216853004
