2016-12-12Fix JBig2 decoding logicweili
While decoding among instances, variable "FIRSTS" should hold its value, not be reset. This was accidently changed by earlier refactoring. BUG=chromium:625848,pdfium:636 Review-Url: https://codereview.chromium.org/2569023002

2016-12-12Fix dotted line drawing for GDI device driverweili
When GDI device driver draws a dotted line, it also clip the line into the device context's bound before drawing. This CL includes a couple fixes: -- When this driver is used for EMF drawing, the drawing is not bound to the device context so clipping is not needed; -- Transformation needs to be applied before clipping since the transformation may move the line into the bound; -- While checking for out-of-bound flags, bit operations are needed to make sure the discarded line is completely out of bound, not partially inside the bound; BUG=chromium:539533 Review-Url: https://codereview.chromium.org/2562533002

2016-12-07Fix the way to check terminal field in interactive formchromium/2945weili

2016-12-07Refcount all the IFX_ stream classes all the time.tsepez
We can remove a lot of "bOwnsStream" logic in the process. Always pass these by const reference, in case the called method wants to hang on to the stream (one exception is where we stick a raw pointer into a void* slot in a context from another layer).

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.

2016-12-05enable skia gradients, fix bugscaryclark
Allow shading to use Skia for some gradients; linear, radial, and coons patch. The corpus uncovered a few gradient-related bugs in the Skia driver which are fixed as well. Fix corpus 11.pdf by ignoring zero area filled paths. PDFium uses CFX_PathData::GetZeroAreaPath() to determine if a path that doesn't enclosing anything should be drawn anyway, and CFX_AggDeviceDriver::GetDriverType() returns 1 so that the empty path is tweaked so that it doesn't draw too often. There are no tests in the corpus that show the utility of this approach; 11.pdf draws correctly if the zero area paths are ignored. Standardize debugging output so that a separate tool can visualize it. R=dsinclair@chromium.org, thestig@chromium.org Review-Url: https://codereview.chromium.org/2530343004

Reasoning: the pTextAdvanceX in CPDF_TextObject::CalcPositionData is being multiplied by horz_scale in CPDF_TextObject::CalcPositionData. Then, m_pCurStates->m_TextX is updated by this amount.

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.
