2017-03-27Fix some ASAN issues in fx_skia_deviceNicolas Pena
- Flush is needed in ~CFX_FxgeDevice, otherwise it may be called after deleting the bitmap, when calling the destructor of the skia device driver. - SkDashPathEffect::Make copies the given intervals instead of owning them, so free the input to that method. - If StartDIBits creates a new CFX_ImageRenderer, then the corresponding CancelDIBits needs to delete the handle.

2017-03-27fix new tab crash in skia clip stackCary Clark
The crash on the new tab page is triggered by processing a transparency. This creates a new Skia device in CPDF_RenderStatus::LoadSMask(): // cpdf_renderstatus.cpp # 2557 if (!bitmap_device.Create(width, height, format, nullptr)) which sets the Skia clip stack to empty. It then calls RenderObjectList() RenderSingleObject() ProcessClipPath() which resets the clip stack; // cpdf_renderstatus.cpp # 1882 m_LastClipPath = ClipPath; m_pDevice->RestoreState(true); At this point m_LastClipPath contains {m_Ref={m_pObject={m_pObj=empty } } } The impelemntation in CFX_AggDeviceDriver::RestoreState() is // fx_agg_driver.cpp # 1283 if (m_StateStack.empty()) return; This hides unbalanced save/restores, but reworking PDFium to balance is nontrivial.

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

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.

Transparencies and bitmap patterns need to be unpremultiplied after Skia renders them so that PDFium can use its own compositing.

2016-11-21use skia textcaryclark
This adds text to the _SUPPORT_SKIA_PATHS_ variant. The output of the test corpus has more differences, but no feature changes or dropouts that I can see. The text is a bit lighter. Bungeman thinks this is because of our support of SRGB color, although the fonts also look different so maybe there's more to the story. The output looks compatible with the variations I see in Adobe Reader and Firefox on the same platform. There's probably more text tuning to do. Additionally, this turns off the caching feature for this variation. Caching can't work because the drawing alternates between Skia and PDFium's native blits, so any state caching won't know about changes and drawing performed by the other.
