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

2016-07-24Use actual type instead CFX_Deletableweili
Change two places that used CFX_Deletable to use actual types. This makes the type more obvious, and avoids unnecessary casts. Review-Url: https://codereview.chromium.org/2180443002

2016-07-15Use CPDF_Dictionary::SetAtReference instead of CPDF_Dictionary::AddReference.jaepark
The definitions of CPDF_Dictionary::SetAtReference and CPDF_Dictionary::AddReference are identical, and AddReference is only used once. So remove CPDF_Dictionary::AddReference method and use CPDF_Dictionary::SetAtReference instead. Review-Url: https://codereview.chromium.org/2161453002

2016-07-06copy graphics state fullycaryclark
The dash parameters where not copied; the copy could point at random data and cause corpus tests to hang when testing Skia. PDFium measures text directly by calling FreeType. Turn off hinting altogether in Skia so that drawn text matches the metrics that PDFium measures. Premultiply bits retrieved from images, and check to see that the device bits are always premultiplied. Look for null graphics state and matrices.

This change contains files in core/fpdfapi directory. This is part of the efforts to make PDFium code compilable by Clang chromium style plugins. The changes are mainly the following: -- move inline constructor/destructor of complex class/struct out-of-line; -- add constructor/destructor of complex class/struct if not explicitly defined; -- add explicit out-of-line copy constructor when needed; -- move inline virtual functions out-of-line; -- Properly mark virtual functions with 'override'; -- some minor cleanups; BUG=pdfium:469 Review-Url: https://codereview.chromium.org/2060973002
