CFX_FontCache refactoring: after this CL: Only one global CFX_FontCache used. Any cached items from it, are released, when its are not used. BUG=79367,48791 The fonts was not cleared after unloading pages. Test pdf: http://www.nasa.gov/pdf/750614main_NASA_FY_2014_Budget_Estimates-508.pdf For this file, we have ~5 fonts per page, which equal ~1 Mb per page. In this PDF we have 670 pages, as result after slow scrolling(reading) full document we have ~600 Mb fonts data in memory. memory usage of PDF Plugin: before this CL: ~660 Mb after this CL: ~100 Mb Review-Url: https://codereview.chromium.org/2158023002

2016-08-29Use ->() in CPDF_ColorStatetsepez
Move methods to CPDF_ColorStateData. Move MakePrivateCopy() methods to call sites. Remove now-empty cpdf_colorstate.cpp file. Review-Url: https://codereview.chromium.org/2291763002
2016-08-29Replace wrapper methods in CPDF_Path with -> operator.tsepez
These just invoked exaclty the same methodes in the underlying xxxData class, which we can now do with just a ->() Move some methods to the xxxData class, where they belong. In doing so, put MakePrivateCopy() calls at each callsite for those methods that made a copy. Review-Url: https://codereview.chromium.org/2286983002
2016-08-26Add -> operators to CFX_CountRef.chromium/2842tsepez
Allows CFX_CountRefs to behave more like pointers. Rename SetNull() to Clear() for consistency with other ptrs. Change GetPrivateCopy() into MakePrivateCopy() with no return, since the -> operators are clearer than getting an object pointer. Review-Url: https://codereview.chromium.org/2283113002
2016-08-24Allow CPDF_Font to use fallback fontsnpm
Added a vector of pointers to CFX_Fonts in the class CPDF_Font, so that fallback fonts may be used. In CPDF_CharPosList::Load, the glyphs for each character are calculated. When m_Font does not support a character, a fallback font is selected and the character is rendered using that font. This meant adding an attribute to FXTEXT_CHARPOS so it knows which font renders it. Also, methods in fpdf_render_text.cpp now may need to call device drawing methods multiple times because these only support one font at a time. In CPDF_TextRenderer::DrawNormalText and in CPDF_TextRenderer::DrawTextPath, the device drawing method is called as few times as possible by grouping contiguous characters rendered by the same font. In CPDF_RenderStatus::DrawTextPathWithPattern, drawing was already done one character at a time, but precalculating CFX_FaceCache. Now, the face cache is precalculated for all of the fallback fonts. The list of fallback fonts does not include tha main font. Otherwise the list would be of raw pointers to avoid double free problems. For now, the font Arial is used as fallback. This should fix the issue of not seeing Latin characters displayed when bad fonts are used. However, this should be improved. Tested manually using the file in the bug, plus a font directory containing a font that supports Hangul but not Latin. This font is chosen as the substitute font, but Latin characters are now being rendered. Design proposal: go/pdfium_fallbackfonts BUG=pdfium:358 Review-Url: https://codereview.chromium.org/2276653002

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

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

2016-06-13Make code compile with clang_use_chrome_plugin (part I)weili
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
