* [PDF] Add support for SrcIn, SrcOut, DstIn, DstOut xfermodes.Gravatar vandebo@chromium.org2011-05-13
| | | | | | | | | | 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.

* [PDF] Add support for Clear, Src, Dst, DstOver xfermodes.Gravatar vandebo@chromium.org2011-05-09
| | | | | | | | 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.

* [PDF] Fix setting of existing clip for layers.Gravatar vandebo@chromium.org2011-05-09
| | | | | | | | 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.

* [PDF] Refactor content stream creation in SkPDFDevice to support more xfermodes.Gravatar vandebo@chromium.org2011-05-09
| | | | | | | | | | | 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.

* [PDF] Fix fallout from r1217.Gravatar vandebo@chromium.org2011-05-02
| | | | | | | | | | | The width and height we pass to SkDevice must be postive. Shader can no longer use negative coordinates (without transform). Shader unflip matrix should use same values as passed to SkPDFDevice (height). Most Shader dictionary entries should be scalars and not ints.

* [PDF] Add support for Shaders.Gravatar vandebo@chromium.org2011-03-08
| | | | | | | | | | | | - 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.

| | | | | | | | | | | | | | | | | | | | | | | | | Sorry this is such a large CL. It was very exploratory for me to make this work. - Add an interface to SkFontHost to retrieve font information and provide NULL implementations on all platforms except Linux. - Segment large Type 1 fonts into fonts with shared resources with 255 glyphs each. - Convert the various Type 1 formats to the form PDF wants. - Update font as we draw text instead of as part of the graphical state. - Remove built-in font support, we can't really use it. Other changes I can pull out to a separate CL if you like. - Add SkTScopedPtr class. - Fix double free of resources. - Fix bug in resource unique-ifying code. - Don't print anything for any empty clip path. - Fix copy paste error - MiterLimit. - Fix sign extension bug in SkPDFString - Fix FlateTest rename that was missed on a previous commit.
