| | | | | | | | | | | | | | | Also, de-dup shader better. - SkBitmapKeyFromImage function factors out image de-dup code. - SkPDFUtils::ToBitmap funtion factors out to-bitmap code - make_image_shader function now takes Image rather than Bitmap. All tests render the same. Some are significantly smaller PDFs.

* SkPDF: Refactor PDFShader to use ShTHashMap<>Gravatar Hal Canary2017-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | my tests run ~14% faster. - Split out gradient shaders from image shaders. new compilation unit: SkPDFGradientShader - Common functions InverseTransformBBox and PopulateTilingPatternDict moved to SkPDFUtils - Split SkPDFShader::State into image and gradient structures. - SkPDFCanon is now a simpler structure, with no logic of its own. I am considering just moving all of its fields into SkPDFDocument - SkPDFShader::State (the image/fallback shader) now is POD, making the use of a hashmap for canonicalization straightforward. Formerly, we used a linear search. - Do not bother trying to canonicalize the falback image shader. - SkPDFGradientShader::Key is not POD; comparison of two objects requires looking at the contents of two variable-sized arrays. We now pre-calculate the hash of the arrays using SkOpts::hash and store a hash for the object in the fHash field. Using that hash, we can now canonicalize using a hashmap instead of a linar search! - several static functions renamed to follow style guidelines - stop using codeFunction function pointer; I find that less clear than it could be. - operator==() for SkPDFShader::State and SkPDFGradientShader::Key is now much simpler and can now be inlined. - SkArrayEqual template in SkPDFUtils.h No change to PDF output.

* [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] 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.
