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.

2017-02-13Clean up CPDF_TextObject a bitNicolas Pena
Modernizing CPDF_TextObject a little bit, in preparation for the addition of APIs for adding text to PDFs. m_pCharCodes, m_pCharPos are now vectors, this caused some propagation to other classes. Also m_Pos is now a point. Note that GetItemInfo is being changed in another CL, so did minimal changes there.

2016-11-17Move CPDF_RenderStatus from render_intnpm
Moved CPDF_RenderStatus to its own class and removed unused methods. I only added some spaces and removed some {}s in cpdf_renderstatus.cpp. Will do cleanup of the file as a followup because it would be too hard to keep track of what's changed in this CL.
