2011-05-18[PDF] Implement clear xfermode with a mask instead of pushing the clip down.vandebo@chromium.org
This approach is much less likely to use an SkRegion and ends up working better for Webkit. Review URL: http://codereview.appspot.com/4550057 git-svn-id: http://skia.googlecode.com/svn/trunk/src@1375 2bbb7eff-a529-9590-31e7-b0007b416f81

2011-05-13[PDF] Add support for SrcIn, SrcOut, DstIn, DstOut xfermodes.vandebo@chromium.org
This change uses the soft mask (aka soft clip) functionality of PDF to implement the xfermodes. It has to put existing content (dst) into a form xobject as well as putting the new (src) content into a different form xobject. It then draws one of them with the other as the soft mask. To accomplish this, we add a call to finishContentEntry after each call to setUpContentEntry - this is kind of a hack, but I don't see a better way to extract src. Unfortunately, soft mask is specified in the Graphic State PDF object (and not in the form xobject), so when handling one of these modes, we add a one time GS object to set the soft mask and invoke a simple GS to reset the soft mask when done.

2011-05-09[PDF] Add support for Clear, Src, Dst, DstOver xfermodes.vandebo@chromium.org
This uses the refactoring in http://codereview.appspot.com/4459041/ to add support for additional xfer modes. Calling setupContentEntry may affect previous content entries (removing, reordering, or modifying their clip) and indicates to the caller if it should draw the new item or not.

2011-05-09[PDF] Fix setting of existing clip for layers.vandebo@chromium.org
The current approach of setting the existing clip just before drawing a layer into a device doesn't work. SkDevice::clear() uses existing clip before that and if we need to put the content in a transparency group (i.e. for SrcIn xfermode), we need a valid existing clip. Instead, change the factory to use a special constructor when creating a layer device.

2011-05-09[PDF] Refactor content stream creation in SkPDFDevice to support more xfermodes.vandebo@chromium.org
Instead of writing all drawing and state updates into the final content stream immediately, this change creates a new ContentEntry each time the transform, clip, or paint changes. Drawing is done into a stream in the ContentEntry. When the consumer asks for the content, we combine all the ContentEntries with appropriate updates to the state (clip, transform, paint) in between. This allows us to modify the clip even after a drawing has completed. It also lets us remove ContentEntries with no drawing. Further optimization can be done to better use the stack features of PDF, for now we follow the previous model of having a single clip followed by a single transform on the graphic state stack. Push rectangle logic into SkPDFUtil::AppendRectangle. Change private functions to adhere to coding standards.

2011-03-08[PDF] Add support for Shaders.vandebo@chromium.org
- Shaders, or as they are referred to in PDF, patterns, are drawn in the coordinate system of the initial page, so when we canonicalize them, we have to consider the current transform and where they are constructed. - Image shaders are tiled by default, this makes repeat and mirror modes easy, but means we have to draw a pattern as large as the current clip to support clamp mode. - Gradient shaders are implemented with type 4 functions, which are basically small snippets of post script code. I've tried to make the code generation modular and heavily commented to make it easy to understand or expand.

SkSafeRef() and SkSafeUnref(). This is basically a bug waiting to happen. An optimizing compiler can remove checks for null on "this" if it chooses. However, SkRefCnt::safeRef() relies on precisely this check... void SkRefCnt::safeRef() { if (this) { this->ref(); } } Since a compiler might skip the if-clause, it breaks the intention of this method, hence its removal. static inline void SkSafeRef(SkRefCnt* obj) { if (obj) { obj->ref(); } } This form is not ignored by an optimizing compile, so we use it instead. git-svn-id: http://skia.googlecode.com/svn/trunk/src@762 2bbb7eff-a529-9590-31e7-b0007b416f81
