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

2016-05-27Workaround dubious casting between CXFA_Object and void* in FXJSEtsepez
This is just a crock to get things working until we fix the underlying issue. When there's single-inheritance, it may often work in practice to C-style (reinterpret) cast a Derived* ptr to void* and then back to a Base* ptr. One place where this blows up is if Derived has virtual functions but Base does not, in which case the world will be offset by the size of a vtable ptr. Because of the use of void* types in FXJSE, the above was happening when setting a CXFA_ThisProxy (Derived, virtual) to be a global object (void*). This would then be cast back to a CFXA_Object (Base, non-virtual) and chaos is ensured. Not sure how far back this goes. Along the way, pick up some tidying which was necessary for simplicity while tracking this down. BUG=613607 Review-Url: https://codereview.chromium.org/2015143005
2016-05-27Avoid two C-style FX_WCHAR* casts in pdfiumbrucedawson
FX_WCHAR* casts were hiding a number of misuses of narrow strings in pdfium, which /analyze identified. Now that those are fixed I did a search for other instances of (FX_WCHAR*) to see if any other bugs were lurking. No bugs were found but one unnecessary cast and one that should be a const_cast were identified. This change fixes those. No behavioral change. Review-Url: https://codereview.chromium.org/2024463002
