2017-03-28Refcount all CFX_DIBSources (and subclasses) all the time.Tom Sepez
There are currently several ownership models for these objects, including ad-hoc logic for sharing and deletion, and the now-redundant CFX_DIBitmapRef externally-counted handle to the DIBs. Replace them all with the internal refcount scheme.

2016-12-06re-enable skia cachingchromium/2944caryclark
This permits consecutive path drawing or text drawing to combine if their graphics state matches. This speeds up rendering considerably when PDFium draws in many small parts. It also allows discarding changes to the clip state that have no effect from draw to draw. All corpus tests draw equivalently with caching enabled or disabled. Change the member order in CPDF_PageRenderContext so the device is flushed before the referencing annotation is deleted. Add more printf style debugging for test draws.

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.
