2016-09-19Remove duplicated charset definitions, and move them to fx_font.hnpm
PWL_FontMap does not need its own charset definitions. fx_edit.h does not need to define DEFAULT_CHARSET. XFA have their own definitions. They look different in that most are MAC or MSWin charset definitions. So they are left untouched. public/fpdf_sysfontinfo.h duplicate ones were left untouched due to being in public folder.

2016-09-14Map glyph bitmap in LookUpGlyphBitmap even when unsuccessfulnpm
CFX_FaceCache::LookUpGlyphBitMap should remember its unsuccessful glyph bitmap calculations. This is especially important if there are a lot of repeated requests for the same glyph with large bitmaps (which means long calculations in freetype). With this CL, the pdf in the bug below will be rendered quickly. BUG=chromium:638856 Review-Url: https://codereview.chromium.org/2338883004

2016-09-08Fix memory management errors for font loading and copyingweili
A few issues are fixed: --Change variable |m_bLogic| in CFX_Font to |m_bShallowCopy| to reflect its meaning better; --For a shallow copy of font, we must guarantee that the copied font will not be deleted until the shallow copy is deleted. So need to increase the src font's refcount when copying it; --The stream |m_pOwnedStream| needs to have matched new/delete These errors need to be fixed before we can properly delete all the fonts to address the leaks.

2016-09-06Move CPDF_GraphState to CFX_GraphStatetsepez
The FX layer is spying on its private data, so make the job of ref-counting it live in FX as well, instead of up a layer at pdfapi. Pre-cursor to making this private and passing the graph state itself everywhere. Review-Url: https://codereview.chromium.org/2314223002

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.

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.

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

2016-07-06copy 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.
