Add an interface to decode frames beyond the first in SkCodec, and
add an implementation for SkGifCodec.
Add getFrameData to SkCodec. This method reads ahead in the stream
to return a vector containing meta data about each frame in the image.
This is not required in order to decode frames beyond the first, but
it allows a client to learn extra information:
- how long the frame should be displayed
- whether a frame should be blended with a prior frame, allowing the
client to provide the prior frame to speed up decoding
Add a new fields to SkCodec::Options:
- fFrameIndex
- fHasPriorFrame
The API is designed so that SkCodec never caches frames. If a
client wants a frame beyond the first, they specify the frame in
Options.fFrameIndex. If the client does not have the
frame's required frame (the frame that this frame must be blended on
top of) cached, they pass false for
Options.fHasPriorFrame. Unless the frame is
independent, the codec will then recursively decode all frames
necessary to decode fFrameIndex. If the client has the required frame
cached, they can put it in the dst they pass to the codec, and the
codec will only draw fFrameIndex onto it.
Replace SkGifCodec's scanline decoding support with progressive
decoding, and update the tests accordingly.
Implement new APIs in SkGifCodec. Instead of using gif_lib, use
GIFImageReader, imported from Chromium (along with its copyright
headers) with the following changes:
- SkGifCodec is now the client
- Replace blink types
- Combine GIFColorMap::buildTable and ::getTable into a method that
creates and returns an SkColorTable
- Input comes from an SkStream, instead of a SegmentReader. Add
SkStreamBuffer, which buffers the (potentially partial) stream in
order to decode progressively.
(FIXME: This requires copying data that previously was read directly
from the SegmentReader. Does this hurt performance? If so, can we
fix it?)
- Remove UMA code
- Instead of reporting screen width and height to the client, allow the
client to query for it
- Fail earlier if the first frame AND screen have size of zero
- Compute required previous frame when adding a new one
- Move GIFParseQuery from GIFImageDecoder to GIFImageReader
- Allow parsing up to a specific frame (to skip parsing the rest of the
stream if a client only wants the first frame)
- Compute whether the first frame has alpha and supports index 8, to
create the SkImageInfo. This happens before reporting that the size
has been decoded.
Add GIFImageDecoder::haveDecodedRow to SkGifCodec, imported from
Chromium (along with its copyright header), with the following changes:
- Add support for sampling
- Use the swizzler
- Keep track of the rows decoded
- Do *not* keep track of whether we've seen alpha
Remove SkCodec::kOutOfOrder_SkScanlineOrder, which was only used by GIF
scanline decoding.
Call onRewind even if there is no stream (SkGifCodec needs to clear its
decoded state so it will decode from the beginning).
Add a method to SkSwizzler to access the offset into the dst, taking
subsetting into account.
Add a GM that animates a GIF.
Add tests for the new APIs.
*** Behavior changes:
* Previously, we reported that an image with a subset frame and no transparent
index was opaque and used the background index (if present) to fill the
background. This is necessary in order to support index 8, but it does not
match viewers/browsers I have seen. Examples:
- Chromium and Gimp render the background transparent
- Firefox, Safari, Linux Image Viewer, Safari Preview clip to the frame (for
a single frame image)
This CL matches Chromium's behavior and renders the background transparent.
This allows us to have consistent behavior across products and simplifies
the code (relative to what we would have to do to continue the old behavior
on Android). It also means that we will no longer support index 8 for some
GIFs.
* Stop checking for GIFSTAMP - all GIFs should be either 89a or 87a.
This matches Chromium. I suspect that bugs would have been reported if valid
GIFs started with "GIFVER" instead of "GIF89a" or "GIF87a" (but did not decode
in Chromium).
*** Future work not included in this CL:
* Move some checks out of haveDecodedRow, since they are the same for the
entire frame e.g.
- intersecting the frameRect with the full image size
- whether there is a color table
* Change when we write transparent pixels
- In some cases, Chromium deemed this unnecessary, but I suspect it is slower
than the fallback case. There will continue to be cases where we should
*not* write them, but for e.g. the first pass where we have already
cleared to transparent (which we may also be able to skip) writing the
transparent pixels will not make anything incorrect.
* Report color type and alpha type per frame
- Depending on alpha values, disposal methods, frame rects, etc, subsequent
frames may have different properties than the first.
* Skip copies of the encoded data
- We copy the encoded data in case the stream is one that cannot be rewound,
so we can parse and then decode (possibly not immediately). For some input
streams, this is unnecessary.
- I was concerned this cause a performance regression, but on average the
new code is faster than the old for the images I tested [1].
- It may cause a performance regression for Chromium, though, where we can
always move back in the stream, so this should be addressed.

We check this define to know which intrinsics we can call safely. The -msse flags set it for us on non-MSVC, but MSVC has no such switch. We do this in GYP (and Chrome's GN) too. No need for any defines on :avx or :hsw targets... the /arch:AVX and /arch:AVX2 do set SK_CPU_SSE_LEVEL for us.

skpbench is a benchmarking suite for skps that aims to generate 100%
repeatable results. The initial commit consists of three parts:
skpbench
A minimalist program whose sole purpose is to open an skp file,
benchmark it on a single config, and exit. No tiling, looping, or
other fanciness is used; it just draws the skp whole into a size-
matched render target and syncs the GPU after each draw.
Limiting the entire process to a single config/skp pair helps to keep
the results repeatable.
skpbench.py
A wrapper to execute the skpbench binary with various configs and skps.
It also monitors the output in order to filter out and re-run results
with an unacceptable stddev.
In the future this script will lock down and monitor clocks and
temperatures.
parseskpbench.py
A utility for parsing skpbench output into a spreadsheet.

Android's the easiest place to start supporting Vulkan, so it's up first.
ndk_api becomes user-specifiable so that the Vulkan bots can kick it up
to 24, the first release supporting Vulkan. The defaults remain the same:
18 for 32-bit and 21 for 64-bit, the first release supporting 64-bit.
To test this, I set ndk_api=24 and skia_use_vulkan=true in GN, then

What do you think of this? It's basically what you wrote, factored differently.
Flipping on skia_use_freetype will enable the SkFontHost_Freetype*.cpp files
via the :typeface_freetype target.
Then we just pull out the SkFontMgr Fuchsia wants to use into its own little
:fontmgr_fuchsia target. No major difference here, except the availability
of freetype headers, etc, is a bit more tightly scoped to just those that
need them.
We (obviously?) don't have Fuchsia builders, so I've got to rely on you for sanity testing this.

Our tools use third-party libraries pretty freely, some of which may not
be available in other GN environments (e.g. Fuchsia). Most can also not
function when Skia is built as a shared library.
fiddle stands alone as the exception to both those points: it depends on
only Skia, and works fine with both a shared or static library.
So guard everything but fiddle with this flag skia_enable_tools, disabled
when we're building for Fuchsia or when we're build a shared library.
This CL has a couple of little tweaks to Fiddle to keep it working:
- divorce it from :tool_utils, instead just building SkForceLinking.cpp itself;
- fix up a buggy rebase_path() that was accidentally working when we depended
on :tool_utils;
- drop test_only: it now only requires production-code dependencies.
The SkImageEncoder Create* methods need to be SK_API if we want SkForceLinking
to work across .so's. Without this, SkForceLinking needs to be part of Skia; it
can't be part of the application using Skia.
The rest is mostly just a re-indent under if (skia_enable_tools),

This will be handy for folks who don't have libwebp, like Fuchsia.
I convinced myself that this is done right by:
- building in all three modes (default and explicitly set both ways);
- looking at verbose Ninja logs to see the presence/lack of SK_HAS_WEBP_LIBRARY;
- running dm -m Codec, which passes with libwebp and segfault without it.
If this is viable, I intend to make all third-party dependencies optional
and follow this pattern. :skia should link and degrade gracefully without
any of //third_party. It's okay for tools to have hard third-party
dependencies; we just need them to get past the `gn gen` stage without them.

If you want to try this out, the DOCS_PREVIEW link is a quickstart.
Are the GrGLCreateNativeInteface_* meant to be part of Skia-the-library
or just used by testing tools? I've got it written here as tool-only,
but we could easily move it to libskia if it's a thing we want to ship.
I'm honestly not sure I understand how this linked before without a definition
of GrGLCreateNativeInterface(). Or are there two, one real and one no-op
default with some sort of weak linking setup? dlopen()?

exec_script runs every time gn does, which is explicitly on every one of our
bot runs. That should be enough to obviate the .git/logs/HEAD hack.
Easiest way to do this was to swap around find.py's argument order to allow
multiple search directories. This is the root of all the .gyp changes.
This moves the blacklist into BUILD.gn, which I think is nice.
It expands it a little as we're now searching recursively, into include/gpu/vk
which we can't include safely without the Vulkan SDK.
