* SkPDF: Factor SkPDFCatalog into SkPDFObjNumMap and SkPDFSubstituteMapGravatar halcanary2015-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | Motivation: Keep separate features separate. Also, future linearization work will need to have several objNumMap objects share a substituteMap. Also "catalog" has a specific meaning in PDF. This catalog did not map to that catalog. - Modify SkPDFObject::emitObject and SkPDFObject::addResources interface to requiore SkPDFObjNumMap and SkPDFSubstituteMap. - SkPDFObjNumMap const in SkPDFObject::emitObject. - Remove SkPDFCatalog.cpp/.h - Modify SkDocument_PDF.cpp to use new functions - Fold in SkPDFStream::populate - Fold in SkPDFBitmap::emitDict - Move SkPDFObjNumMap and SkPDFSubstituteMap to SkPDFTypes.h - Note (via assert) that SkPDFArray & SkPDFDict don't need to check substitutes. - Remove extra space from SkPDFDict serialization. - SkPDFBitmap SkPDFType0Font SkPDFGraphicState SkPDFStream updated to new interface. - PDFPrimitivesTest updated for new interface.

* Simplify reference management in SkPDFGravatar halcanary2015-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this change, SkPDFObject subclasses were required to track their resources separately from the document structure. (An object has a resource if it depends, via an indirect reference, on another object). This led to a lot of extra code to duplicate effort. I replace the getResources() function with the much simpler addResources() function. I only define a non-trivial addResources() method on arrays, dictionaries, and indirect object references. All other specialized classes simply rely on their parent class's implementation. SkPDFObject::addResources() works by recursively walking the directed graph of object (direct and indirect) references and adding resources to a set. It doesn't matter that there are closed loops in the graph, since we check the set before walking down a branch. - Add SkPDFObject::addResources() virtual function, with four implementations - Remove SkPDFObject::getResources() virtual function and all implementations. - Remove SkPDFObject::GetResourcesHelper() - Remove SkPDFObject::AddResourceHelper() - In SkPDFCatalog::findObjectIndex(), add an object to the catalog if it doesn't exist yet. - SkPDFCatalog::setSubstitute() no longer sets up resources - SkPDFDocument.cpp no longer needs the Streamer object - SkPDFDocument.cpp calls fDocCatalog->addResources to build the resource list. - SkPDFFont::addResource() removed - All SkPDF-::fResource sets removed (they are redundant). - removed SkPDFImage::addSMask() function - SkPDFResourceDict::getReferencedResources() removed. Motivation: this removes quite a bit of code and makes the objects slightly slimmer in memory. Most importantly, this will lead the way towards removing SkPDFObject's inheritance from SkRefCnt, which will greatly simplify everything. Testing: I usually test changes to the PDF backend by comparing checksums of PDF files rendered from GMs and SKPs before and after the change. This change both re-orders and re-numbers the indirect PDF objects. I used the qpdf program to normalize the PDFs and then compared the normalized outputs from before and after the change; they matched. Review URL: https://codereview.chromium.org/870333002
* Make SkStream *not* ref counted.Gravatar scroggo2015-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SkStream is a stateful object, so it does not make sense for it to have multiple owners. Make SkStream inherit directly from SkNoncopyable. Update methods which previously called SkStream::ref() (e.g. SkImageDecoder::buildTileIndex() and SkFrontBufferedStream::Create(), which required the existing owners to call SkStream::unref()) to take ownership of their SkStream parameters and delete when done (including on failure). Switch all SkAutoTUnref<SkStream>s to SkAutoTDelete<SkStream>s. In some cases this means heap allocating streams that were previously stack allocated. Respect ownership rules of SkTypeface::CreateFromStream() and SkImageDecoder::buildTileIndex(). Update the comments for exceptional methods which do not affect the ownership of their SkStream parameters (e.g. SkPicture::CreateFromStream() and SkTypeface::Deserialize()) to be explicit about ownership. Remove test_stream_life, which tested that buildTileIndex() behaved correctly when SkStream was a ref counted object. The test does not make sense now that it is not. In SkPDFStream, remove the SkMemoryStream member. Instead of using it, create a new SkMemoryStream to pass to fDataStream (which is now an SkAutoTDelete). Make other pdf rasterizers behave like SkPDFDocumentToBitmap. SkPDFDocumentToBitmap delete the SkStream, so do the same in the following pdf rasterizers: SkPopplerRasterizePDF SkNativeRasterizePDF SkNoRasterizePDF Requires a change to Android, which currently treats SkStreams as ref counted objects.

* SkPDFCanonGravatar halcanary2015-01-21
| | | | | | | | | | | | | | | | | SkPDFCanon's fields and methods will eventually become part of SkPDFDocument/SkDocument_PDF. For now, it exists as a singleton to preflight that transition. This replaces three global arrays in SkPDFFont, SkPDFShader, and SkPDFGraphicsContext. This code is still thread-unsafe (http://skbug.com/2683), but moving this functionality into SkPDFDocument will fix that. This CL does not change pdf output from either GMs or SKPs. This change also simplifies some code around the SkPDFCanon methods. BUG=skia:2683 Review URL: https://codereview.chromium.org/842253003
* Change function signature of SkPDFObject::emitObject.Gravatar halcanary2015-01-12
| | | | | | | | | | | | | Replace virutal SkPDFObject::emitObject(s, c, true) with non-virtual SkPDFObject::emitIndirectObject(s, c), since none of the subclasses do (or should do) anything different. Replace object->emitObject(s, c, false) with object->emitObject(s, c) This is one step in simplifying the SkPDFObject interface to allow for the next step in refactoring.

* Fix int16_t for glyphs, const glyphs, and clarify glyph loop.Gravatar bungeman2014-10-03
| | | | | | | | | | | | | | | | | | Several places in the PDF code are using int16_t for glyphs. With newer NotoSans fonts, all possible glyph ids are being used, so this can lead to problems. The PDF glyphs from text code returns the text for the glyphs if the encoding is for glyphs. However, it returns this using an unsafe const cast which is hiding possible bugs and preventing correct use of const in other places. The way the glyph loop in SkPDFDevice::drawPosText is written uses a '--i' in the loop, which makes it appear this can loop forever. I don't believe it can, but it is an unecessary code folding. We should also at least assert the forward progress correctness here. Review URL: https://codereview.chromium.org/626613002
