2016-11-15Create a subset of skia support for paths onlycaryclark
This is a continuation of https://codereview.chromium.org/2346483006/ This removes the need for agg, without providing full Skia support. It doesn't work yet, but it does compile and run for simple PDFs. R=dsinclair@google.com Review-Url: https://codereview.chromium.org/2491693002

2016-10-17lcms: reject NaN when reading float numberskcwu
LerpFloat functions expect input values are normal float. They first clamp values to the range of [0.0, 1.0] and then calculate interpolation with the input values. If the input value is NaN, it will lead to heap buffer overflow because the index to LutTable is calculated based on the said value and fclamp(NaN) is not in expected [0.0, 1.0] range. This patch rejects all NaN values earlier when reading float numbers. So it also changed behavior for cases other than LerpFloat. I think it is okay because NaN doesn't make sense for usual calculations. BUG=654676 Review-Url: https://codereview.chromium.org/2422553002

The patch (https://codereview.chromium.org/2284063002) for Issue 618267 was insufficient. The integer overflow still could be triggered and could lead to heap buffer overflow.

2016-10-04Fix cmdStageAllocMatrix parameter swapkcwu
For cmdStageAllocMatrix, InputChans is length of Matrix, OutputChans is length of Offsets. The original code will allocate NewElem->Offset with length Cols=InputChans (cmslut.c:417).

2016-06-13fix skia + windows + gncaryclark
The Skia Windows build for PDFium differs from the Skia Chromium build in that it uses FreeType within PDFium and Direct Write within Chromium. This allows Chrome to match the UI of Windows, and allows PDFium to use FreeType to measure and draw. When PDFium was updated to use gn, the settings from Chrome were used as the basis for the PDFium settings. Subsequently, PDFium built with Skia on Windows drew text incorrectly as it used FreeType to look up the font glyphs and Direct Write to draw them. This fixes the gn files, and also fixes an error that crept into the now less-used gyp files. R=dsinclair@chromium.org BUG= Review-Url: https://codereview.chromium.org/2055353002

2016-05-16Use chromium_code standard for PDFium GYP compilationweili
Define and use chromium_code to be used in standalone PDFium GYP build so that PDFium code can have more stringent warning level. This is also enabled on GN build by default so that GYP and GN builds can have consistent compilation results. Also enable chromium_code for PDFium compilation in Chromium since most of the warnings are cleared. The left ones are clearly marked and will be addressed soon. A few more clean-ups for the build: -- Remove the suppression of sign-compare warnings for Clang since the code is clean and the warning can be re-enabled. -- Re-enable "treat warning as errors" on Mac -- Add a flag to make GCC build works as well.
