- Encoders and decoders always assume kIgnore.
- They are less opinionated about F16 and color space,
we just trust the color space that's passed in, and
put that directly in the image (no sRGB encoding).
- SkBitmap and SkPixmap read/write pixels functions were
defaulting to kResepct, those are now always kIgnore.
- Many other bits of plumbing are simplified, and I
added a default of kIgnore to SkImage::makeColorSpace,
so we can phase out that argument entirely.
- Still need to add defaults to other public APIs that
take SkTransferFunctionBehavior.
- This makes gold think that we've dramatically changed
the contents of all F16 images, but that's because
it doesn't understand the (now linear) color space
that's embedded. Once we triage them all once, they
will work fine (and they'll look perfect in the browser).

ImageDecoder will respect the origin, but BitmapFactory will maintain
its current behavior of not respecting it. Add an option to respect it.
In addition, add support for reading the EXIF data from a WEBP. This
seems to be an uncommon use case, but is occasionally used when
converting from a JPEG. Add 8 WEBPs, all converted (with cwebp) from
their analogous JPEG files already checked in.

Bug: b/63909536
Android's ImageDecoder API takes as input an arbitrary width and height
to scale the image to. Internally, this uses SkAndroidCodec to sample,
and then (if not a perfect match) scales to the desired size with
drawing.
computeSampledSize is a modified version of what ImageDecoder currently
does to convert from arbitrary dimensions to a sampleSize. Moving it
here allows it to be shared by SkAnimatedImage. The modified version
also corrects two bugs:
- a client using the dimensions returned by getSampledDimensions
previously may have resulted in ImageDecoder decoding to a larger
size and then scaling it. (example found in tests: dog.jpg is
180 x 180. getSampledDimensions(8) returns 23 x 23, but the old
method resulted in using sampleSize of 7 and downscaling the resulting
25 x 25 image.)
- recompute the sampleSize based on the size returned by
getSampledDimensions.

Bug: b/63909536
SkAnimatedImage is a simple drawable for animating a GIF. Thread-safety
is left up to the client. At most two bitmaps are stored in the
drawable; one for the current frame and one for a frame that may need to
be restored. The backup frame prevents some cases where we would
otherwise have to re-decode from the beginning of the image.
The API lets the client set the time value, and decodes to match that
time.
TODO:
- Callback for when the animation is complete
- Ability to use SkAndroidCodec
- Modify the loop count (or leave that up to client?)
- Better and/or client-specific caching
Other changes:

Hide SkEncodedInfo
Bug: skia:7353
Bug: skia:6839
This contains information that is not necessary for clients to know. The
Color enum tells the number of components in the input, but this is only
interesting internally (to the SkSwizzler).
Similarly, the Alpha enum differs from SkAlphaType in that it has
kBinary instead of kPremul. This is useful information only internally
for determining whether the SkColorSpaceXform needs to premultiply.
The bitsPerComponent is potentially useful for a client; Android (in
SkAndroidCodec) uses it to determine the SkColorType. Rather than
exposing bitsPerComponent, make SkAndroidCodec a friend so it can
access the SkEncodedInfo. A future change will change SkCodec to
recommend F16 for bitsPerComponent > 8, but that will be more involved;
it was the reason for the revert of this CL.
Switch conversionSupported to use an SkColorType, which is enough info.
Replace the SkEncodedInfo::Alpha field on SkCodec::FrameInfo with an
SkAlphaType.
SkCodec still needs an SkEncodedInfo, so move its header (which is
already not SK_API) to include/private.

This reverts commit c6f7a4ffa9.
Reason for revert: Causing differences in Gold, stemming from the fact that this changes the recommended SkImageInfo for 16 bits-per-component PNG from N32 to F16.
- an F16 bitmap already png-encodes to a 16 bits-per-component PNG, but it does not encode a linear colorspace (possibly a bug?). when we decode this PNG using getInfo(), it fails because it has an F16 color type and non-linear colorspace. (In the encode-srgb-png gm, this results in blank results for F16.) We could correct this on the encoder side, but it seems possible that a 16 bits-per-component PNG could be encoded with a different color space. In that case, we'd want SkCodec to recommend F16/SRGBLinear, but I think we'd want the SkCodec to store the encoded SkColorSpace so that we can Xform between the two. Currently SkCodec only stores one color space, so that will require a refactor.
- When decoding 16-bits-per-component PNGs, we are now decoding them to F16. This shows differences in Gold. The srgb/gpu results now look more like F16. I think this is fine.

Previously, SkGifCodec treated an error in the LZW data as incomplete,
since we can still draw the partially decoded image. But a client doing
incremental decodes needs to distinguish this from truly incomplete
data. In the case of an error, the client should not attempt to provide
more data and decode again.
Add kErrorInInput, and return it when SkGifCodec sees a fatal error.

Add a new private method to SkCodec that handles Options.fFrameIndex:
- Check to ensure the index is valid
- Call onGetFrameCount to force parsing the stream
- Recursively call getPixels (it should be complete, so no need for
incremental decoding) to decode the prior frame if necessary
- Zero fill a RestoreBGColor frame
Call the method in getPixels and startIncrementalDecode, and remove
duplicate code from GIF and WEBP.
Remove support for scaling frames beyond the first, which is currently
unused.
Preserve the feature of SkGifCodec that it will only parse to the end
of the first frame if the first frame is asked for. (Also note that
when we continue a partial frame, we won't force parsing the full
stream.) If the client only wants the first frame, parsing the rest
would be unnecessary. But if the client wants the second, we assume
they will want any remaining frames, so we parse the remainder of the
stream. This simplifies the code (so SkCodec does not have to ask its
subclass to parse up to a particular frame).
Update tests that relied on the old behavior:
- Codec_partialAnim now hardcodes the bytes needed. Previously it
relied on the old behavior that GIF only parsed up to the frame being
decoded.
- Codec_skipFullParse now only tests the first frame, since that is the
case where it is important to skip a full parse.

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.)

- 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.

Add a version of getFrameInfo that returns information about a single
frame, allowing a client to skip creating the entire vector.
Add getFrameCount, for determining the number of frames in the image.
Reimplement std::vector<FrameInfo> getFrameInfo with the new methods.
Updates to the test:
- getFrameInfo(size_t, FrameInfo*) fails before parsing
- Test both versions of getFrameInfo
- Recreate the codec between tests, to test parsing

Add SkCodec::FrameInfo::fAlphaType. The SkImageInfo for the SkCodec
specifies the SkAlphaType for the first frame, but the opacity can vary
from frame to frame.
When determining the required frame, also compute whether a frame has
alpha. Update how we determine the required frame, which had bugs.
(Update a test that had an incorrect required frame as a result.)
Add new test images covering cases that have been fixed:
- randPixelsAnim2.gif
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
methods and transparencies.

This is a step towards removing the non-linear blending flag from
SkColorSpace. The flag on SkColorSpace used to control the premul
behavior - now it is controlled by this option.

This indicates whether the frame has been fully received, i.e. the
stream contains enough data to decode to the end of the frame.
A client may want to use this to know whether they should attempt to
decode this frame, if they do not want to decode partial frames.

I want to land this so we can start testing color space aware
decoding on Android. In particular, it will be interesting to
see how linear premultiplication will affect existing content.
This will only modify BitmapRegionDecoder behavior. I'll
follow up with a similar change to BitmapFactory.cpp in Android.
This will cause image diffs on Gold.
