* SkPDF: ResourceDict replaced by factory functionGravatar halcanary2015-04-09
| | | | | | | | | Motivation: Having a class here was unnecessary, since the only thing that set this class apart was how it is created, not how it behaves. BUG=skia:3585 Review URL: https://codereview.chromium.org/1068343003
* 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

* Use SkSet to fix issue when pdf generates an exp number of resources.Gravatar edisonn@google.com2013-02-27
| | | | | | | | | | | | | | | The problem fixed - http://code.google.com/p/skia/issues/detail?id=940 - is that getResources will recursively obtain all child resource recursively without checking for duplicates. If we have lots of duplicates, then we try to build a very large vector (exponential with the number of nodes usually) and sooner or later we end up using too much memory and crash. A possible solution could have been to make sure resources do not have duplicates, but that requirement is impractical, and it this leaves the solution fragile, if there is any issue in the tree, we crash. When we emit the pdf, the large number of duplicates is not an issue, because SkPDFCatalog::addObject will deal with duplicates. I have run the gm with --config pdf, and the images are 100% same bits, while the pdfs have the same size but some very small changes, the order of some objects.
