This is breaking the roll by using it, since Chromium doesn't build it.

* SkPDF: Implement drawImage*() properlyGravatar halcanary2015-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | drawImage calls now properly embeds the original jpeg. NOTE: drawBitmap*() calls no longer embed JPEG files when possible (this is in advance of eliminating bitmaps backed by encoded data). Chromium has already moved from drawBitmap to drawImage. Comparisons: control: total PDF drawImage/drawBitmap calls: 8010 total PDF jpeg images: 0 total PDF regular images: 3581 experiament: total PDF drawImage/drawBitmap calls: 8014 total PDF jpeg images: 271 total PDF regular images: 3311 total PDF regular images: 3582 (271 + 3311) When comparing rendered output there were perceptual differences in the following four GMs: colorcube, emboss, colormatrix, and tablecolorfilter. All of these differences were improvements (that is, closer to the 8888 rendering) due fixing a bug with colorfilters and forgetting to call notifyPixelsChanged. No SKPs had perceptual differences. Total PDF size dropped from 133964 kB to 126276 kB, a 5.7% improvement (mostly due to restoring use of JPG images in SKPs). BUG=skia:4370 Review URL: https://codereview.chromium.org/1372783003

* PDF: Correctly embed JPEG images directly into PDF output.Gravatar halcanary2015-04-17
| | | | | | | | | We only embed images with YUV planes. That should only grab the subset of color JPEGs supported by PDF. BUG=skia:3180 Review URL: https://codereview.chromium.org/1025773002
* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://codereview.chromium.org/950633003/) Reason for revert: static void draw(SkCanvas* canvas, const SkPaint& p, const SkBitmap& src, SkColorType colorType, const char text[]) { SkASSERT(src.colorType() == colorType); canvas->drawBitmap(src, 0.0f, 0.0f); canvas->drawText(text, strlen(text), 0.0f, 12.0f, p); } This assert is firing, at least on macs, where all images get decoded into 32bit at the moment.

* PDF: Canon now owns a reference to all interned objectsGravatar halcanary2015-02-27
| | | | | | | | | | | | | Add SkPDFCanon::reset function to unref all objects. No longer possible to remove object from canon Motivation: this doesn't change these object's lifetime, (they will still be fully unrefed when SkDocument::close() is called, but we no longer have to remove them from the array when their destructor is called.

* miniz support in SkFlate / PDFGravatar mtklein2015-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | - Adds miniz.c v115_r4 (latest release) to third_party. - Merges SkDeflateWStream into SkFlate so including "miniz.c" links without duplicating symbols. The only interesting code change I've made is to remove the line fImpl->fZStream.data_type = Z_BINARY; from SkDeflateWStream::SkDeflateWStream(). miniz doesn't have Z_BINARY defined, and as far as I can tell, both zlib and miniz ignore data_type. We should be able to swap skflate.gyp's dependency between zlib.gyp:zlib and zlib.gyp:miniz at will (except of course on Windows) if we're interested in zlib itself. I've left android framework on its own zlib. I think this all means we can stop defining SK_NO_FLATE on Windows. I'll leave the possible cleanup of SK_NO_FLATE itself for another time. Might be we always want to keep this dependency optional. CQ_EXTRA_TRYBOTS=client.skia:Test-Win8-ShuttleA-HD7770-x86-Debug-Trybot BUG=skia: Review URL: https://codereview.chromium.org/957323003

* PDF: Add (low-memory) SkPDFBitmap classGravatar halcanary2015-02-18
Also: Add SkDeflateWStream and associated unit tests. SkPDFBitmap is a replacement for SkPDFImage. As of now, it only supports 8888 bitmaps (the most common case). SkPDFBitmap takes very little extra memory (aside from refing the bitmap's pixels), and its emitObject() does not cache any data. The SkPDFBitmap::Create function will check the canon for duplicates. This can reduce the size of the output PDF. Motivation: this gives another ~40% decrease in PDF memory overhead TODO: Support other ColorTypes and scrap SkPDFImage.
