* Remove experimental/PdfViewerGravatar halcanary2015-08-04
| | | | | | | | Motivation: maintaining this code doesn't seem worth the time, since no one seems to be using it. If someone wants to use it in the future, just revert this CL. Review URL: https://codereview.chromium.org/1266093003

* 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.

* Separate and update PDF_DIFF_TRACE_IN_PNGGravatar scroggo@google.com2013-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move its functionality out of readToken() and into its own class. Callers of the previous readToken() now call SkPdfNativeTokenizer::readToken(), which in turn calls a function for writing the diff to a file, if the caller requests it and PDF_TRACE_DIFF_IN_PNG is defined. Do not attempt to draw a diff for compatibility sections, which we do not draw. Use SkString to handle string manipulation. Hide globals only used by PDF_TRACE_DIFF_IN_PNG behind that flag. Remove hasVisualEffects, which always returns true. Rename gLastOpKeyword to gOpCounter for clarity. In SkPdfNativeTokenizer, set fEmpty to true when the entire stream has been read. Use SkBitmap::copyTo instead of manually copying an SkBitmap.

* Restructuring of PdfViewer code.Gravatar scroggo@google.com2013-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only change in behavior is that SkPdfAllocator on SkPdfContext is no longer allocated on the heap. In general, I have just moved code. SkPdfContext: Inherit from SkNoncopyable. Make SkPdfContext directly own fTmpPageAllocator. fTmpPageAllocator is created when SkPdfContext is, and destroyed at the same time as well, so there is no reason for the extra allocation. Add the function parseStream. This eliminates code duplication, and allows making fTmpPageAllocator private. Move PdfMainLooper into the implementation file, since it is now only used by parseStream. Move SkTDictWithDefaultConstructor and render stats info here, in support of PdfMainLooper. SkPdfTokenLooper: Rename PdfTokenLooper to SkPdfTokenLooper. Move readToken here, unchanged. Remove tokenizer(), which is unused. SkPdfNativeDoc: Remove tokenizerOfPage and tokenizerOfBuffer, which are unused. SkPdfOps: Move gPdfOps and PdfOperatorRenderer into a header file (hidden for now), so they can be accessed by both SkPdfRenderer.cpp and SkPdfContext.cpp. SkPdfRenderer: Harvest things into other files: PdfMainLooper (and the code that calls it) -> SkPdfContext. readToken -> SkPdfTokenLooper.

* Changes to SkTDStackNester.Gravatar scroggo@google.com2013-11-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SkTDStackNester is a class used by PdfViewer to assist in saving and restoring the PDF state. Clean up and test this class. Add some documentation. Add FIXME's where I have questions to resolve. Fix a bug where fNestingLevel was not initialized. Remove a commented out line of code copied over from SkTDStack. Rename SkTDStackNester::nests() to nestingLevel() and make it const. Remove unnecessary predeclaration and friend declaration. Remove index() (both const and non-const versions). They were unused, return something that may not be expected (index from the top, rather than from the bottom), and don't work to get any elements in earlier Recs once the first one is full. Report a warning if the nesting level goes above the maximum level, or if we attempt to bring it below zero. Prevent fNestingLevel from dropping below zero. Add kUnusedObject_SkPdfIssue, and use it where appropriate.

* Pdfviewer refactoring.Gravatar scroggo@google.com2013-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mostly superficial changes, to help me make sure I understand the code while making modifications. SkPdfRenderer: First class I'm modifying. Move it into include/ and src/ directories. Inherit from SkNoncopyable. Replace load() with factory function which returns NULL if the load fails. Remove unload() and loaded(), which no longer make sense, since the factory will return NULL on a failure to load, and unload() happens on destruction. Use a const char* for loading a PDF, following the convention of SkStream::NewFromFile. Remove unnecessary call to sqrt in SkPDFNativeRenderToBitmap. Also in SkPDFNativeRenderToBitmap, use an appropriate SkScalar macro to convert to an integer. Use this-> when calling member functions. pdf_viewer_main.cpp: Call the new interface for SkPdfRenderer. gyp files: Refer to the new location of SkPdfRenderer.
