Previously, we reported the first image as soon as it was available. As
a result, in crrev.com/2565323003, InitializeNewFrame might be called
before the metadata is known, meaning it would read the wrong metadata.
Instead of looking at the imagesCount(), SkGifCodec::NewFromStream looks
at frameContext(0), which may still exist even if it's not yet counted
in imagesCount().
Add a test that confirms the desired behavior.

Update NewFromStream to report an error on failure to create an
SkCodec, so that a client can distinguish between
- not enough data
- invalid data
In Chromium, this will allow blink::ImageDecoder to call SetFailed if
the stream is invalid early and we never create an SkCodec. Without
this, ImageDecoder will keep trying to create an SkCodec when it
receives more data.

SkCodec sets fRequiredFrame to be the earliest possible frame that a
given frame can depend on. e.g.
- Frame A fills the screen, Keep
- Frame B does not cover A, Keep
- Frame C covers B but not A, and is opaque
Frame C can depend on either A or B. SkCodec already reports that C
depends on A. This CL allows a client of SkCodec to use either A or
B to create C.
Also expose the DisposalMethod. Since any frame between A and C can
be used to create C except for DisposePrevious frames, the client
needs to be able to know the disposal method so they do not try to
use such a frame to create C.
Further, the disposal method can be used to give the client a better
idea whether they will continue to need a frame. (e.g. if frame i is
DisposePrevious and depends on i-1, the client may not want to steal
i-1 to create i, since i+1 may also depend on i-1.)

(No change to the public API, but changed a header file)
SkWebpCodec:
- Implement onGetFrameCount, onGetFrameInfo, and onGetRepetitionCount
- Respect the alpha reported by libwebp. Although the spec states that
it is only a hint, the libwebp encoder uses it properly. Respecting
allows us to draw opaque images faster and decode them to 565. This
also matches other SkCodecs (and Chromium).
- onGetPixels:
- Decode the frame requested, recursively decoding required frame if
necessary
- When blending with a prior frame, use SkRasterPipeline
SkCodec:
- Move check for negative index to getFrameInfo
- Reset the colorXform if one is not needed
SkCodecAnimation:
- Add new blend enum, for WebP's (and APNG's) non-blending option
SkFrameHolder:
- New base classes for frames and the owner of the frames, allowing
code sharing between SkWebpCodec and SkGifCodec (particularly for
determining whether a frame has alpha and what frame it depends on)
- When moving items from SkGIFFrameContext, use Skia conventions (i.e.
int instead of unsigned)
- Rename "delay time" to "duration", to match e.g. SkFrameInfo::
fDuration
SkGifImageReader:
- Move pieces to SkFrameHolder, and adapt to changes made in the
process
- Make setAlphaAndRequiredFrame (now on the base class SkFrameHolder)
more general to support webp, and add support for frames that do not
blend
- Change SkGIFFrameContext from a struct to a class, to match how we
use the distinction elsewhere (i.e. struct is a small object with
public fields)
- Rework hasTransparentPixel (now hasTransparency, since it returns true
in some cases where there is not a transparent pixel) to better fit
with the modified setAlphaAndRequiredFrame. Also be more consistent
when there is no transparent pixel but no color map.
- Simplify an if condition that was previously simplified in 2d61e717
but accidentally got reverted in a4db9be6
CodecAnimTest:
- Test new animated webp files
- Rearrange the test to more cleanly print alpha type mismatches for
the first frame
resources:
- webp-animated.webp
- animated webp from Chromium
- blendBG.webp
- new webp file using bits of webp-animated-semitransparent4.webp
from Chromium
- tests required frame and alpha when using the non-blending mode
- frames have the following properties:
- Frame 0: no alpha, fills screen
- Frame 1: alpha, fills screen
- Frame 2: no alpha, fills screen
- Frame 3: alpha, fills screen, blendBG
- Frame 4: no alpha, fills screen, blendBG
- Frame 5: alpha, blendBG
- Frame 6: covers 4, has alpha, blendBG
- also used to test decoding to 565 if the new frame data has alpha
but blends onto an opaque frame
DM.cpp:
- Test animated images to non-native 8888 and unpremul
DMSrcSink.cpp:
- Do not test non-native 8888 decodes to f16 dst
- Test unpremul decodes to f16
- Copy a frame of an animated image prior to drawing, since in unpremul
mode, the DM code will premultiply first.

It has the following frames:
A (keep)
B (keep) (subset)
C (disposePrevious) (covers B)
D (any) (does *not* cover B)
B and C depend on A, but D depends on B, since after disposing C, B
should be visible again.
- alphabetAnim.gif
Includes frames which fill the image size, with different disposal

The zlib source we DEPS in for testing has been patched with x86
optimizations, some requring SSE2, some SSE4.2, and some PCLMULQDQ
(between SSE4.2 and AVX).
Might as well turn them on?
zlib actually boils everything down into one do-we-have-everything bit.
That's a little weird... I don't see any real reason not to use
fill_window_sse() on a machine with SSE2 but not SSE4.2. Whatever.
While tweaking libpng settings is really where it's at to make PNG
encoding faster, this is kind of a nice little cherry on top. Won't
help people who are using their own zlib, of course.

This makes is_official_build turn off all development targets and
features in Skia, including building third-party dependencies from
source.
This will intentionally break some external users, who will find
themselves no longer able to find third-party headers or link against
third-party libraries. These users have been building with our testing
third-party dependencies unknowingly. They'll need to either explicitly
turn back on building each dependency from source
(skia_use_system_foo=false) or disable that dependency entirely
(skia_use_foo=false).
is_skia_standalone is now basically !is_official_build, so I've
propagated that through, removing is_skia_standalone. In a few places
we were using it as a stand-in for defined(ndk), so I've just written
defined(ndk) there. Duh.
gn_to_bp:
is_offical_build's new strength also makes gn_to_bp.py simpler to
write. In spirit, Android builds are official Skia builds that also
build DM and nanobench.
It seems that SkJumper (src/jumper/*) is (unintentionally) enabled
on Android. Switching to an is_official_build would have disabled
that. But as that accidental launch seems to have gone fine, I've
kept it explicitly enabled.
In the end, no changes to Android.bp or its SkUserConfig.h.
The -Mini builder no longer needs to explicitly disable tools.

Code and docs are at: https://github.com/ocornut/imgui
ImGui is an open source immediate mode GUI library that's
lightweight and fairly simply to integrate. Widget functions
return their state, and the library emits vertex and index
data to render everything. It's got a huge set of built-in
widgets and really robust layout control.
For the initial integration, I had to fix up event handling
in the viewer's app framework (to get mouse wheel and more
keys, etc...).
The new viewer 'Debug' window is toggled with the space bar.
For this change, I've added one feature to that window: the
slide picker. It's got a list of all slides, with filtering
support, and the ability to click to switch slides.
I also included the ImGui 'Demo' window (toggled with 'g').
This is nicely laid out, and includes examples of pretty
much everything the library can do. It also serves as good
documentation - find something that looks like what you want,
and then go look at the corresponding code (all of it is in
imgui_demo.cpp).
I have other CLs with other features (like directly editing
the primaries of the working color space), but I wanted to
land this chunk first, then start adding more features.
Other than adding new debugging features, there are few
more outstanding work items:
1) Raster doesn't render the GUI correctly, due to non-
invertible pos -> UV matrices. Florin is working on that.
2) Touch inputs aren't being routed yet, so the GUI isn't
usable on Android yet. Might also be tough to work with,
given the size.
3) ImGui has clipboard integration (that's why it wants
the C, X, and V keys), but we need to wire it up to the
OS' clipboard functions.
4) Draw commands can carry a void* payload to support
drawing images (using whatever mechanism the engine has).
I'd like to set that up (probably using SkImage*), which
makes it really easy to add visualization of off-screen
images in GMs, etc...

Previously, getFrameInfo might report a frame that was truncated prior
to setting its requiredFrame. As a result, fRequiredFrame may be
different depending on how much data has already been received.
If there is a local color table, do not report the frame until the
color table has been received, since that is used to determine
fRequiredFrame. If there is no local color table, set fRequiredFrame
and report the frame after reading the header.

If a frame does not have a valid transparent index and it covers the
prior frame, it does not really depend on that frame. Instead, it
depends on the frame that the prior frame depends on.
Determine this once we have parsed the local color map (if any), so a
transparent index out of range of the color map is not considered
valid.
Share code that determines whether a frame has a transparent pixel.
Add a test that we compute the dependencies correctly. randPixelsAnim.gif
has 13 frames. After the first, the frames cover all combinations of
- Whether the prior frame was keep, restoreBG or restoreToPrevious
- Whether the new frame covers the prior frame
- Whether the new frame has a transparent pixel
(It only does so when using a global color table. It may make sense to
expand the test to also cover using local color tables.)
The test caught a bug where we incorrectly reused an existing
SkColorTable for a different frame. Fix that bug by keeping track of
the transparent index associated with the current SkColorTable.

If there is enough data in the stream to read the reported canvas size,
but not enough to read the first image's header, we do not know the
true canvas size, since we may expand it to fit the first frame. In
that case, return nullptr from NewFromStream.
Add a test.
SkGifCodec.cpp:
Correct a comment - parse returns false if there is a fatal error.
parse() returning true does not guarantee that the size was found.
Instead of checking the width and height, check to see whether the
first frame exists and has its header defined. If not, we do not yet
know the true canvas size. Assert that the canvas size is non-zero,
which is a fatal error from parse.
SkGifImageReader.cpp:
Move the code to set the header defined before the SkGIFSizeQuery exit
condition. This allows SkGifCodec to check the first frame's header to
determine whether the size is known.
GifTest.cpp:
Add a test which truncates the file just before the image header (and
after the global header). Prior to the other changes, this would create
an SkCodec. For an image that needs its canvas size expanded, the
SkCodec would have an incorrect size.

randPixels.gif now needs more than half of its data to create an

This stems from a behavior difference between Skia and Chrome.
In Skia, we want to write transparent pixels as often as possible.
(It's faster than checking if we should skip each pixel.)
In Chrome, they avoid writing transparent pixels unless
absolutely necessary.
We were cautious about changing behavior when this first landed,
but this is easier to think about in a smaller change (right now).
(1) We can always write transparent pixels when we are writing
an independent frame.
(2) There is no need for the progressiveDisplay() check. We
only ever use progressive display methods on the first
frame - and the first frame is always independent.

565 cannot take the !writeTransparentPixels path, so disable it for
cases where we might have to take that path.
This only affects frames beyond the first. If the first frame has
a transparent pixel, it will be marked as non-opaque, so we cannot
decode to 565 anyway.

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.

Attempt to take over all *SAN builds.
MSAN has a lot of coordination required between gn/BUILD.gn and gn_flavor.py.
I'd like to follow up to move more of this into gn/BUILD.gn, to make it easier
to use locally.
The compile steps should be much faster now. We no longer build CMake
and Clang for every run, instead using the clang_linux CIPD package. This
removes the need for all the third_party/externals/llvm/... dependencies.
Similarly, since we're using the clang_linux package, we no longer depend
on Chrome's Clang, and thus no longer need to sync chromium on these bots.
Instead of packaging up MSAN libraries and llvm-symbolizer in the compile
output, I have the test / perf bots also depend on the clang_linux package.
These do not vary from build to build.
No more need for the xsan.blacklist -include hack: Clang, GN, and Ninja
all track changes to xsan.blacklist without our help.
This has the incidental effect of upgrading the compiler used by *SAN
bots from Clang 3.8 to Clang 3.9.

Once you have downloaded an android NDK, you can set the ndk GN arg to use it.
E.g. my gn.args looks like:
is_debug = false
ndk = "/opt/android-ndk"
This should be enough to get you going for an arm64 build. You ought to be able to tweak that to other architectures by changing target_cpu to "arm", "x86", "x86-64", etc. That won't quite work until I follow this up a bit, but the skeleton is there.

This fixes the build on Linux (dep on third_party:zlib -> third_party/zlib).
I've moved declare_args() {} back to each .gn file... seems like args want

Additionally, refactor all the common third_party config and warning flag
changes into a template, third_party. This lets it all live together in a
.gni: at head unwanted_configs can be in a .gni (it's just a variable) but
config("no_warnings") (and thus third_party_configs) cannot, as configs

What we've got here is a little GN MVP. It's lacking any knobs and doesn't yet build anything but libskia, zlib, libpng, and libjpeg-turbo. I've been hopping back and forth between Linux at work and Mac at home. These seem to be at least partially working, enough to build and run cmake/example.cpp.
The xcode backend seems to work. From here, we can start exploring how to handle other backends (cmake,Android make, Google3). There are a couple things I want to try:
- add another backend like vs or xcode to GN directly
- intercept via a custom toolchain
- reverse from ninja -t commands
That last option seems kind of fun.
This tries to piggyback on Chrome's GN setup as much as possible. Chrome's got quite a lot figured out, and we're basically required to do this if we want to have a single GN build system shareable by Chrome, our bots, and other clients.
This pulls in some new DEPS:
- build: Chrome's GN configuration, and much more
- buildtools: hashes for gn binary, pulled via hooks
- tools/clang: hashes for Chrome's clang, pulled via hooks into third_party/llvm-build
It additionally symlinks tools/gyp to third_party/externals/gyp. GN pulls some stuff from tools/gyp on Mac.
Have not yet tried building for Windows, Android, or iOS.

The microhttpd build is now done in the build tree as opposed to in a

The microhttpd build script uses os.path.join so that absolute paths
do not confuse the build. This allows compatibility with the cmake
gyp generator as CMake likes to pass absolute paths.
The microhttpd gyp target is now marked as 'none' since it is not
a 'static_library' target (which directs gyp to compile sources into
a static library). The dependencies to the action are updated to the
minimum required for sane re-building.
The everything gyp target now depends on the skiaserve gyp target.
This means that when using skia_build_server=1, building 'most' will
build skiaserve, but when skia_build_server is not defined the
skiaserve target will still be available if specified manually.
The old json.gyp is removed as it currently does not build anything.

Local timing says this 4-byte Paeth function takes about 0.3x the time the serial libpng code does, dropping from ~10 cycles per byte to ~2.9.
bpp=4 is mainly an easy demo. This approach can work for any bpp up to 16, 1 pixel at a time, at roughly the same cost per pixel. Doing more than 1 pixel at a time is a tricky math problem I have yet to attempt to solve.
Everything here can be trivially downgraded to MMX, supporting bpp up to 8. It seems to be a little slower (~3.5 cycles per byte), but it would make the code compatible with every x86 that can still power on.
I've tried four approaches:
- this way;
- doing things naively in 16-bit;
- a 16-bit version that requires division by 3 (i.e. mulhi_epu16(..., 0x5580) );
- a mostly 8-bit version of the same.
They're all fine, but this one is consistently the fastest I've measured.
I'd be happy to settle on the naive 16-bit version too, which would have a very clear implementation that's only minorly slower than this version. The other two are way more complicated, and would require us to draw some serious ASCII diagrams to explain.
I have learned that the .skp serialization tests (serialize-8888) have a nice side effect of testing the correctness of these filters!
(Since writing the description above, I've bumped things up to {Paeth,Sub,Avg} x { 3 bpp, 4 bpp }.)

Turn back on DM testing for scaled webp, now that it should no longer
use uninitialized memory.
Fix a warning in config.h

It turns out that gyp (kind of) has support for cross
compiling with a different host and target. We simply
need to specify CC_host and CC_target instead of CC.
Making this change allows us to compile yasm on a Linux
host for Android.
We run into problems on Mac because
the linker on a Mac host requires different command line
arguments than the linker on the Android target. In
looking through the code for gyp itself and speaking to
Ben, it doesn't appear to me that gyp supports passing
different arguments to host and target linkers.
I would imagine that we would have similar problems on
Windows.
Below is a link to a CL that would fix this issue in gyp.
It looks like it has been dropped for a long time.
Thanks to Ben for this link!

Also I'm adding a link to the build instructions for Chrome
(thanks again Ben). It looks like they only support
building for Android from Linux.
https://code.google.com/p/chromium/wiki/AndroidBuildInstructions
My next steps are:
1) Getting in touch with Torne or someone else with gyp to
see if people are aware of this issue or interested in
fixing it.
2) Deciding if skia should care about this issue.
3) Deciding if skia should work around this issue.
It'd be really great to hear your thoughts on (2) and (3).
My first thought is that we shouldn't care because, as
long as we always compile the production copy of skia for
Android on Linux, we will get the fast code. Is this
a valid conclusion? Is there a way to write Android apps
on Mac that accidentally use the slower code?
If we do care, there are workarounds:
For Mac, we can check in a yasm binary - it's a little
smaller than the one I am deleting in this CL :-/
For Windows, we *might* be able to use the yasm.exe binary
already in externals (we get this from DEPS because this is
how chromium uses yasm on Windows).
Are there other platforms that we care about?
Let me know what you think!

All platforms except android are configured to use the statically linked copy
of libpng. Android uses the system provided dynamic copy for SkImageDecoder
and the static copy for SkCodec. The exception being android framework builds
that currently use the dynamic copy everywhere.
This CL also enables NEON optimizations for libpng.

Reason for revert:
breaking the nexus_9 and ios builds.

DM:
Add a flag to use SkCodec instead of SkImageDecoder.
SkCodec:
Base class for codecs, allowing creation from an SkStream or an SkData.
An SkCodec, on creation, knows properties of the data like its width and height. Further calls can be used to generate the image.
TODO: Add scanline iterator
SkPngCodec:
New decoder for png. Wraps libpng. The code has been repurposed from SkImageDecoder_libpng.
TODO: Handle other destination colortypes
TODO: Substitute the transpose color
TODO: Allow silencing warnings
TODO: Use RGB instead of filler?
TODO: sRGB
SkSwizzler:
Simplified version of SkScaledSampler. Unlike the sampler, this object does no sampling.
TODO: Implement other swizzles.
Requires a gclient sync to pull down libpng.

Partially in preparation for building libpng on Windows.
Also, this makes us consistent across platforms for PDF.
Uses the version of zlib checked into the Chromium tree.
Remove miniz, which is replaced by zlib.
Review URL: https://codereview.chromium.org/966963002
- 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.

The Mac fontconfig just #defines the cache directory, which works fine if fontconfig never has to look up any fonts (the case until now). If it has to actually find fonts from the disk, the cache directory and config directory need to be properly defined as well as running fc-cache to populate the cache directory.
Populating the cache directory can take some time, but should only happen on a clean build. To remove this extra time, we have to not build poppler on Mac, which can now be accomplished with GYP_DEFINES="skia_mac_poppler=0"
