2017-09-06Convert FX_STRSIZE int->size_tRyan Harrison
Change the underlying type for FX_STRSIZE to size_t from int. This will make the value unsigned and thus all values in the range of the type will be valid. This allows for the final remove of negative length strings, but also introduces a some casting and functional errors, since many parts of the code base assume that FX_STRSIZE is int or another signed type. This also CL fixes these errors.

2017-09-01Cleanup usages of Mid(foo, 1), Right(1), and Left(1)chromium/3203Ryan Harrison
Mid(foo, 1) is equivalent to [foo], if all you want is the character. Similarly Left(1) is [0]. It is faster also, since it does not need to create intermediate strings. Right(1) is a touch more tricky, since it requires something like GetLength() ? [GetLength() - 1] : 0;. A new method, Last() has been added to perform this character extraction. Multiple call sites have been updated to use more efficient/simpler syntax. There are a number of call sites that use on these patterns, but based on the surrounding context we actually need/want a string, so they have not been modified.

2017-08-30Convert int* references to FX_STRSIZERyan Harrison
Through out the code base there are numerous places where variables are declared using a signed integer type when interacting with the string classes, since they assume that FX_STRSIZE is 'int'. As part of changing the underling type of FX_STRSIZE to be unsigned, these locations are being changed to use FX_STRSIZE. This is necessary as part of converting the type, but has been broken off into a separate CL, since it should be low risk. Some related cleanups that are low risk are included as part of this CL.

2017-08-02Rewrite how string Insert() methods handle out of bound indicesRyan Harrison
The existing behaviour was to clamp the provided index to the valid bounds. This would lead to programming errors being hidden, since inserting would still do something even if the index calculation was wrong. The behaviour of these methods has been changed to instead early return when this occurs, returning the old length value. The caller can check if the call to Insert actually did anything by comparing the returned value to the length before calling insert. All of the existing calls to Insert have been tested by running all of the tests with asserts in the Insert method to check the index is in bounds. Additionally the call sites have been manually inspected. The majority of them are of the form Insert(0, foo) and the rest tend to be in a loop advancing from 0 to length. Convenience methods InsertAtFront/InsertAtBack have been added to handle calling Insert when the intent is for the character to be added to the beginning or end of the string. Existing call sites to Insert that do this have been converted. This work was originally being performed to check if there would be any issues in these methods with making FX_STRSIZE unsigned.

The various string/byte classes support Mid(), Left(), and Right() for extracting substrings. Mid() can handle all possible cases, but Left() and Right() are useful for common cases and more explicit about what is going on. Calls like Mid(offset, length - offset) can be converted to Right(length - offset). Calls like Mid(0, length) can be converted to Left(length). If the substring being extracted does not extend all the way to one of the edges of the string, then Mid() still needs to be used.

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.

The chain of destructors may attempt to use m_pDocPage after it has been set to null by the unique_ptr destructor. Verify it is still present before using it from any code that may be called from some other CPDF_ destructor.

2017-04-20Cleanup the fx_extension code.Dan Sinclair
This CL cleans up the fx_extension file. The stream code was moved to fx_stream. IFX_FileAccess was removed and CFX_CRTFileAccess split to its own file. Code shuffled from header to cpp file.

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.

2017-04-07Tweak CFDF_Font::AppendChar()Tom Sepez
Pass in/out argument as a pointer. Avoid pointless malloc just to copy in multibyte case. Then we can avoid special-casing the single-byte case.

2017-04-04RefCount CPDF_StreamAcc all the time.Tom Sepez
Pass stream argument to constructor; it feels like a stream accessor should always be made from a stream rather than passing one in after the fact.
