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.

files. This is the third CL to separate fx_ge into classes, one per file. All fx_ge.h includes had to be replaced with new includes The method definitions for CFX_FxgeDevice were not moved to a single file. These methods are defined in two folders different from fxge/ge, so they were left untouched for now. Review-Url: https://codereview.chromium.org/2223213002
2016-08-08Move CFX_ClipRgn and CFX_PathData into their own files.npm
This is the second CL in an attempt to split up the classes in fxge/include/fx_ge.h into their own files. CFX_ClipRgn is moved to core/fxge/ge because it is only used in core/fxge. The header for CFX_PathData is left in core/fxge/include since it is used elsewhere. Review-Url: https://codereview.chromium.org/2216853004

2016-07-06copy graphics state fullycaryclark
The dash parameters where not copied; the copy could point at random data and cause corpus tests to hang when testing Skia. PDFium measures text directly by calling FreeType. Turn off hinting altogether in Skia so that drawn text matches the metrics that PDFium measures. Premultiply bits retrieved from images, and check to see that the device bits are always premultiplied. Look for null graphics state and matrices.

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

2016-05-17Don't use LCD antialiasing if Fontconfig doesn't support hintingthomasanderson
Some Freetype implementations (like the one packaged with Fedora) do not support hinting due to patents 6219025, 6239783, 6307566, 6225973, 6243070, 6393145, 6421054, 6282327, and 6624828; the latest one expires 10/7/19. This makes LCD antialiasing very ugly, so we instead fall back on NORMAL antialiasing.

2016-04-12Record all fonts, not just one per charset.dsinclair
Attempting to open bug_434.pdf on my Linux box would fail with: ../../xfa/fxfa/app/xfa_fwltheme.cpp:96: virtual FWL_ERR CXFA_FWLTheme::Initialize(): Assertion `__null != m_pCalendarFont' failed. I tracked the regression back to [1]. The issue seems to be in CFX_FontManager::AddInstalledFont we will only add one font for a given Charset. In my case I end up loading 6 charsets, but the fonts are all strange ones. When I open the PDF, it fails to find 'Arial' because I've registered these other fonts. To fix this I changed the m_FaceArray into a struct of {name, chraset}. Then we record all fonts into this list and search over that list for the charset when needed. This allows bug_434.pdf to open and the test to pass successfully. 1- https://pdfium.googlesource.com/pdfium/+/fe73e7849b8b4ce49408d2f52f3fc29b370b82b5 Review URL: https://codereview.chromium.org/1874433002
2016-04-12flesh out gradient shaderscaryclark
Using these webpages as guides http://www.globelegislators.org/pdfjs/test/pdfs/alphatrans.pdf http://www.antennahouse.com/antenna1/wp-content/uploads/2015/07/background-image-gradient-1.pdf flesh out the gradient shaders to include the PostScript Type 0 sampling function and to include radial gradients. This CL makes rendering these pages agree with Adobe Reader output. Some of these examples use an Extend array to clip the gradient. Skia does not currently support this natively, so construct the clip manually for now. Other PDF pages may construct gradients using alternate mechanisms -- this code will continue to be refactored as those come to light. In particular, this CL sets up the clip and matrix differently for axial gradients and radial gradients -- while it makes sense to do it one way only, I prefer to defer until I have more examples to work with.
