2016-10-04Use FX_SAFE_UINT32 on CPDF_ToUnicodeMap::Loadnpm
m_Map maps to unsigned integer, but m_MultiCharBuf.GetLength() returns an integer. There will be integer overflow if the length is big, and UBSAN will complain. Thus, using FX_SAFE_UINT32. Replacing with uint32 would work as well: the point is to consider the length as uint instead of int. BUG=chromium:652232 Review-Url: https://codereview.chromium.org/2393573002

2016-10-03Detect resursive loading of type3 font char to avoid infinite loopweili
The original way of detecting loops was passing a level parameter through various functions. This missed some cases which also lead to load type3 font char, for example, FindFont() may call CheckType3FontMetrics() which may eventually lead to LoadChar(). The new way is to store the char loading depth, and abort when the depth exceeds the max. BUG=chromium:651304 Review-Url: https://codereview.chromium.org/2384853002

2016-09-29Remove FX_BOOL from font_int.hnpm
It is not necessary. For some methods, bool can be used instead. For some other methods, the returned boolean is never used, so they can be void. Review-Url: https://codereview.chromium.org/2382803002

2016-09-21Check for overflow in CMap_GetCode.dsinclair
Given a large enough value for the character code it's possible to overflow the conversion to an int. This Cl updates the code to guard against overflow. BUG=chromium:648739 Review-Url: https://codereview.chromium.org/2358023002

2016-09-01Fix CPDF_CIDFont::GlyphFromCharCode for fonts flagged with PDFFONT_SYMBOLICnpm
UnicodeFromCharCode should be tried even if the font is flagged as PDFFONT_SYMBOLIC. The result should be checked in case it's empty. This fixes some corpus tests that were being incorrectly rendered, as well as the bug below. A deps change will be required before landing this CL.

2016-08-30Guard against overflow when calculating font weight.dsinclair
This CL uses the safe math libraries when calculating the font weight from the StemV value as very large values for StemV can cause the signed int to overflow. BUG=chromium:641418 Review-Url: https://codereview.chromium.org/2293633002
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
2016-08-19Avoid signed overflow in CPDF_ToUnicodeMap::StringToCode()tsepez

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 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
