2016-08-16Hidden annotations should not be drawntonikitoo
Now that PDFium supports drawing of more annotation types, it should also respect the "hidden" flag that annotations might feature. For instance, in IE/Acroread if an annotation is flagged as "hidden" it does not get drawn. CL adds a check for the specific "hidden" flag, not drawing annotation that are flagged with it, in order to match IE + acrobat reader behavior. The "flags" definition can be seen by looking at "/F {value}" syntax in a PDF file source, where {value} is an predefined integer value. Test: PDF files being added in [1].

2016-08-16Rename async to linearized when parsingdsinclair
The parser and document refer to async loading and parsing. The code isn't actually async but loading a linearized PDF. This Cl renames the methods to clarify what the code is doing. The LoadDoc() and LoadLinearizedDoc() methods have been refactored to share a common LoadDocInternal() method. Review-Url: https://codereview.chromium.org/2250163002

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.

2016-08-11Relax a check in CPDF_HintTables.thestig
CPDF_HintTables::ReadSharedObjHintTable() unnecessarily constraints a FX_FILESIZE value to an int32_t.
