* Simplify SkColorSpace::MakeICCGravatar Leon Scroggins III2017-10-31
| | | | | | | | | | | | | | | | | | | Rather than restricting the supported ICC types in MakeICC, create any ICC type that we support, and make the client reject them as necessary by querying the SkColorSpace::Type. Remove ICCTypeFlag and replace uses of it with SkColorSpace::Type. This depends on a change in Chromium (https://chromium-review.googlesource.com/c/chromium/src/+/741843). Without that, this change will start allowing non-CMYK images to use CMYK profiles.

| | | | | | | | | | | | | | | | | | | | | | | | | | Most SkCodec subclasses did the following to apply their SkColorSpaceXform: dstFormat = select_xform_format(dstInfo.colorType()); srcFormat = select_xform_format(<something that doesn't change>); xformAlphaType = select_xform_alpha(dstInfo.alphaType(), this->getInfo().alphaType()); this->colorXform()->apply(dstFormat, dst, srcFormat, src, width, xformAlphaType); Consolidate the computation of these parameters into SkCodec and add a new method to SkCodec that calls apply() with those parameters. Add a SkColorSpaceXform::ColorFormat to SkCodec. This allows the new method SkCodec::applyColorXform to supply the ColorFormat. TBR=reed@google.com (No change to public API.)

* Reland "Make SkPngCodec only read as much of the stream as necessary"Gravatar Leon Scroggins III2017-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (Originally uploaded as 13900.) Previously, SkPngCodec assumed that the stream only contained one image, which ended at the end of the stream. It read the stream in arbitrarily-sized chunks, and then passed that data to libpng for processing. If a stream contains more than one image, this may result in reading beyond the end of the image, making future reads read the wrong data. Now, SkPngCodec starts by reading 8 bytes at a time. After the signature, 8 bytes is enough to know which chunk is next and how many bytes are in the chunk. When decoding the size, we stop when we reach IDAT, and when decoding the image, we stop when we reach IEND. This manual parsing is necessary to support APNG, which is planned in the future. It also allows us to remove the SK_GOOGLE3_PNG_HACK, which was a workaround for reading more than necessary at the beginning of the image. Add a test that simulates the issue, by decoding a special stream that reports an error if the codec attempts to read beyond the end. Temporarily disable the partial decoding tests for png. A larger change will be necessary to get those working again, and no clients are currently relying on incrementally decoding PNGs (i.e. decode part of an image, then decode further with more data). Include a workaround for older versions of libpng (e.g. 1.2 in Google3). In older versions, if the row callback is null when the IDAT header is processed, reading the image will fail. When we see the IDAT, we save the length and process a recreated IDAT header later, after the row callback has been set. Bug: skia:5368 Bug:b/34073812 Test: Existing tests, plus a new test in dm.

* Unify ICC support for gray jpegs and gray pngsGravatar Matt Sarett2017-01-13
| | | | | | | | | | | | | | | | | | | | | | (1) Parse ICC gray profiles into RGB SkColorSpace objects. This is easy - "gray transfer fn + white point" is subset of "RGB transfer fns + matrix". This makes it easier/possible for the drawing code to reason about color spaces attached to kGray buffers. (2) Allow gray images to be tagged with gray ICCs OR rgb ICCs. ICC gray forces to designer to use "D50 gray". It is not uncommon to see gray images with RGB profiles - and this actually allows the designer to choose more kinds of gray (ex: sRGB gray). (3) Make SkJpegCodec support gray images with RGB ICCs. (4) Make SkPngCodec support gray images with Gray ICCs. (5) Delete gray from SkColorSpace_A2B - we no longer create these objects for gray profiles.

* SkPngCodec: Add support for 16-bit pngs (step 1)Gravatar Matt Sarett2016-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Android plans to use 16-bit png to encode higher precision assets. This CL should not change any behavior or cause diffs on Gold. It simply moves the 16-bit -> 8-bit strip from libpng to SkSwizzler. As a follow-up, I plan to add support for 16-bit input to SkColorSpaceXform. This will require a new swizzler function that just samples or subsets 16-bit values (but does not strip to 8-bit). An alternative implementation could avoid the additional swizzler functions by deciding whether or not to call png_set_strip() at decode time (we would still need the swizzler fn to sample/subset 16-bit values). I find this strategy to be cleaner than that. I would rather handle 16-bit rgb(a) all the time than *some* of the time. And this is implementation is also more efficient than libpng. Though it is also more skia code. Gray and gray alpha are left alone until I know whether anyone wants high precision gray support. b/32984164 Change-Id: I44e307473526de3f4bba06879c5fffa25d480f56 Reviewed-on: https://skia-review.googlesource.com/6020 Reviewed-by: Leon Scroggins <scroggo@google.com> Commit-Queue: Matt Sarett <msarett@google.com>

| | | | | | | | | | | | | | | | | | | Tool will now check for and output all unsuccessfully parsed ICC profiles in input sksp images if --testColorCorrectionSupported is set as a flag. All ICC-aware codecs had to be slightly modified in order to expose this information, as the logic for accessing the ICC profiles is all within the codecs. If --writeFailedImages is set, it will also output all images whoses ICC profiles were not supported.

* Safely handle unsupported color xforms in SkCodecGravatar Matt Sarett2016-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | (1) The transformation code *should* support any src SkColorSpace that we successfully parse. This is agreed upon internally and by clients. The fact that we currently don't is just a bug... (2) We cannot and will not support all SkColorSpaces as dsts. So if we fail to make a SkColorSpaceXform, we should assume that it was caused by a bad dst color space. The correct response in this case is to return kInvalidConversion. I've rewritten the CL to do this. The fact that weird src spaces will sometimes trigger a kInvalidConversion is just a bug that is being actively worked on.

* Consider the start_coord in interlaced PNGGravatar scroggo2016-10-18
| | | | | | | | | | | | | | crrev.com/2420843003 (DIFFERENT ISSUE) resulted in a slight difference in Gold for interlaced PNGs. The new images appeared to have slid down slightly, implying that we sampled pixels higher (earlier) in the image. It turns out we were not truly taking get_start_coord into account. This CL initializes the srcRow to consider get_start_coord, and should fix the problem/difference.

* Incremental decode: only use subset for subsettingGravatar scroggo2016-10-17
| | | | | | | | | | | | | | | | | | | | | | | In the initial patch, we modified the subset passed to incremental decoding to account for sampling in Y. This allowed SkSampledCodec to use a tighter bounds. But it also means that the implementation cannot distinguish between lines that are excluded due to subsetting and those excluded at the beginning and end due to sampling. This becomes problematic in GIF (crrev.com/2045293002), which may need to fill, requiring it to reconstruct the actual destination. In truth, SkGifCodec does not need to support subsets, but cannot distinguish between the tighter bounds and a true subset. Fix this by passing the scaled subset to incremental decode, without using the tighter bounds. Make SkSampler::rowNeeded take the starting coordinate into account. In SkPngCodec, compute the number of rows needed in the output, and use that as a signal to stop.
