2016-11-23Rename IFWL classes which do not have CFWL equivalentsdsinclair
This CL moves the IFWL classes that do not have CFWL class buddies to have the CFWL name. This CL leaves the tree in a weird state of having CFWL be two hierarchies, one of which is intertwined with the IFWL hierarchy. This should be commited just before the CL to move the rest of IFWL to CFWL. Review-Url: https://codereview.chromium.org/2525083002
2016-11-23fix negative font sizecaryclark
PDF can specify a negative font size to change the y-axis for text. Add support in the Skia driver for that. The cached form for text and paths had fallen out of sync with the uncached code used by skiapaths, so sync that up so that the mainline skia setting has those bug fixes as well. This does not fix the underlying bug in 528103, but gets Skia on parity with native PDFium text rendering. The bold text is still drawn in the wrong place.

2016-11-22handle antialiased rendering as premultipliedcaryclark
Transparencies and bitmap patterns need to be unpremultiplied after Skia renders them so that PDFium can use its own compositing. Also added some linear (i.e. axial) gradient support, although its unclear if any of the test corpus uses this feature. R=dsinclair@chromium.org Review-Url: https://codereview.chromium.org/2520073003

The -build/include setting was masking out build/include_what_you_use. This CL restores them, fixes any build errors, and adds NOLINT as needed.

2016-11-21use skia textcaryclark
This adds text to the _SUPPORT_SKIA_PATHS_ variant. The output of the test corpus has more differences, but no feature changes or dropouts that I can see. The text is a bit lighter. Bungeman thinks this is because of our support of SRGB color, although the fonts also look different so maybe there's more to the story. The output looks compatible with the variations I see in Adobe Reader and Firefox on the same platform. There's probably more text tuning to do. Additionally, this turns off the caching feature for this variation. Caching can't work because the drawing alternates between Skia and PDFium's native blits, so any state caching won't know about changes and drawing performed by the other.

2016-11-17fix corpus testscaryclark
All corpus tests draw reasonably well. There are pixel differences, but no missing features or large scale errors. This was verified by running run_corpus_tests.py on skiapaths and agg build dirs, then running the skdiff tool to generate a report of the pixel difference. For example, after running $ ninja -C out/skia skdiff $ ./out/skia/skdiff /repo/pdfium/out/agg/gen/pdfium/testing/corpus/ /repo/pdfium/out/skiapaths/gen/pdfium/testing/corpus/ ~/aggskiadiffs view the report in a browser at ~/aggskiadiffs/index.html R=dsinclair@chromium.org BUG=skia:5973 Review-Url: https://codereview.chromium.org/2504863003

2016-08-15add native draw bitmap with alpha maskcaryclark
PDFs draw bitmaps with alpha by supplying an image alpha mask along side the image color data. The alpha mask may not be the same scale as the image data. Skia doesn't have a direct mapping for this draw call, but can come close by using the internal SkCompositeShader class. This scales the alpha mask to match the size of the image data, then puts both in the composite shader to draw. There are more things to do: - Allow Alpha8 or Gray8 to draw scaled to a matching device (blit doesn't work today) Temporary code marked with a TODO implements this functionality. - Refactor PDFium to allow SkComposeShader's components to take a matrix. The latter goal will defer drawing so that PDFium doesn't resize the mask, discarding resolution, before Skia has a chance to record it. Additionally fix drawing text with a negative font size.

2016-06-02The PDFium source in core/fxge/dib implements a bit-blitting backend.caryclark
This code has several disadvantages over a more modern graphics engine: - no SIMD support - no GPU support - limited quality Further, calling this code locks in the perceived resolution, so that the output cannot be scaled without additional loss. By directing all bitmap drawing through CFX_SkiaDeviceDriver::StartDIBits, Skia can handle all appropriate bitmap optimizations. To that end, SetDIBits and StretchDIBits now call StartDIBits. Other changes: Skia's bitmaps are premultiplied. PDF contains bitmaps that are unpremultiplied. PDFium appears to use premultiplied bitmaps sometimes, and unpremultiplied bitmaps elsewhere. Add a debug check for unpremultiplied bits in Skia's driver, and add a utility to premultiply PDFium's bitmaps' bits. PDFium supports a 24 bit RGB bitmap padded to a 32 bit word. Set the high byte so that Skia can treat this as an ARGB bitmap. Defer the application of the alpha value to the draw call rather than calling MultiplyAlpha where possible. Allow the destination bitmap to be alpha 8 or argb 32. Review-Url: https://codereview.chromium.org/2025043002
