2017-09-28Cleanup font definesDan Sinclair
Use methods to match font information; cleanup some font code. Change-Id: Ib99c1e466e56723cb5d264d49e1caf9bbbc0daed Reviewed-on: https://pdfium-review.googlesource.com/15072 Reviewed-by: Ryan Harrison <rharrison@chromium.org> Commit-Queue: dsinclair <dsinclair@chromium.org>
2017-09-18Convert string class namesRyan Harrison
Automated using git grep & sed. Replace StringC classes with StringView classes. Remove the CFX_ prefix and put string classes in fxcrt namespace. Change AsStringC() to AsStringView(). Rename tests from TEST(fxcrt, *String*Foo) to TEST(*String*, Foo). Couple of tests needed to have their names regularlized.

2017-08-15Remove GetAt from string classesRyan Harrison
This method duplicates the behaviour of the const [] operator and doesn't offer any additional safety. Folding them into one implementation. SetAt is retained, since implementing the non-const [] operator to replace SetAt has potential performance concerns. Specifically many non-obvious cases of reading an element using [] will cause a realloc & copy.

2017-06-19Add heuristic for improving text rendering in CPDF_CharPosList::LoadNicolas Pena
This CL uses the following algorithm for improving substitute font spacing (we are assuming the text layout is horizontal): * Calculate PDFWidth, the width that the PDF says the glyph should have. * Calculate FTWidth, the width calculated by freetype for the glyph, using the substitute font that we'll use to render it. Note that some embedded fonts have PDFWidth == FTWidth + 1, so we consider that to be matching widths. * If PDFWidth > FTWidth + 1 , move the x coordinate by the difference / 2 so that the glyph is rendered in a more centered spot and the text looks better. * If PDFWidth < FTWidth, transform the glyph horizontally by PDFWidth / FTWidth so that the glyph gets compressed and does not overlap with surrounding glyphs.

2017-04-12Some fixes to the fallback font code.Nicolas Pena
This CL applies several fixes to the fallback font code. - PDFium uses -1 to indicate that no glyph index was found, but freetype uses 0. In CPDF_TrueTypeFont, an index of 0 indicates a freetype failure, which means we should try to find the glyph from a fallback font. - Improve the fallback glyph calculation by going from original font charcode to unicode to fallback font charcode. - Consider the m_ExtGID on Mac when deciding the fallback.
