637680c286 Revert "HEIF decode: add support for 10-bit color format"
This reverts commit 2710bcfc68.

Reason for revert: This CL is preventing the roll into Android because it is causing CTS failures.

469d67e7d9 Expose more info in SkCodec::FrameInfo
Bug: b/160984428

Add more fields to SkCodec::FrameInfo, which describes the properties of
an individual frame in an animated image. This allows a client that
wishes to seek to determine frame dependencies so that they can decode
an arbitrary frame, which in turn will allow SkCodec to remove
SkCodec::FrameInfo::fRequiredFrame. Currently, SkCodec seeks through the
stream to determine frame dependencies, but this is unnecessary work
(and storage) for a client that does not want to seek.

These fields also support the proposed APIs in go/animated-ndk.

Move SkCodecAnimation::Blend from SkCodecAnimationPriv (and delete that
file) into SkCodecAnimation.h. Rename its values to be more clear.

Merge common code for populating SkCodec::FrameInfo.

Add a test for a GIF with offsets outside the range of the image. Note
that libwebp rejects such an image.

Update libgifcodec.

fc4fdc5b25 SkAndroidCodec: Support decoding all frames
Bug: b/160984428
Bug: b/163595585

Add support to SkAndroidCodec for decoding all frames with an
fSampleSize, so that an entire animation can be decoded to a smaller
size.

dm/:
- Test scaled + animated decodes

SkAndroidCodec:
- Make AndroidOptions inherit from SkCodec::Options. This allows
  SkAndroidCodec to use fFrameIndex. (It also combines the two versions
  of fSubset, which is now const for both.)
- Respect fFrameIndex, and call SkCodec::handleFrameIndex to decode
  the required frame.
- Disallow decoding with kRespect + fFrameIndex > 0 if there is a
  non-default orientation. As currently written (except without
  disabling this combination), SkPixmapPriv::Orient would draw the new
  portion of the frame on top of uninitialized pixels, instead of the
  prior frame. This could be fixed by
  - If SkAndroidCodec needs to decode the required frame, it could do so
    without applying the orientation, then decode fFrameIndex, and then
    apply the orientation.
  - If the client provided the required frame, SkAndroidCodec would need
    to un-apply the orientation to get the proper starting state, then
    decode and apply.
  I think it is simpler to force the client to handle the orientation
  externally.

SkCodec:
- Allow SkAndroidCodec to call its private method handleFrameIndex. This
  method handles decoding a required frame, if necessary. When called by
  SkAndroidCodec, it now uses the SkAndroidCodec to check for/decode the
  required frame, so that it will scale properly.
- Call rewindIfNeeded inside handleFrameIndex. handleFrameIndex calls a
  virtual method which may set some state (e.g. in SkJpegCodec). Without
  this change, that state would be reset by rewindIfNeeded.
- Simplify handling a kRestoreBGColor frame. Whether provided or not,
  take the same path to calling zero_rect.
- Updates to zero_rect:
  - Intersect after scaling, which will also check for empty.
  - Round out instead of in - this ensures we don't under-erase
  - Use kFill_ScaleToFit, which better matches the intent.

be0e42cb8f New helpers for SkYUVAInfo when used with pixmaps.
SkYUVAPixmapInfo is a SkYUVAInfo with per-plane color types and row
bytes. It describes a set of pixmaps that make up a planar image.
Consolidates validity checks of the SkYUVAInfo with the color types
and row bytes. It can provide SkImageInfos for each plane and also
assist with configuring planes to share a common allocation.

SkYUVAPixmaps is a collection of SkPixmaps that are valid for a
SkYUVAInfo. It can either wrap existing SkPixmaps or allocate and
own the memory. It consolidates validity checking of SkPixmaps with
the SkYUVAInfo. Replaces sk_gpu_test::YUVAPixmaps.

Minor tweaks to SkYUVAInfo naming, parameter order consistency, adds a
hasAlpha() method.

87d42e5d12 A new way to specify YUVA planar data from SkCodec to SkImage_Lazy
Tunnels through SkImageGenerator as well.

The new SkCodec interface doesn't assume three 8 bit planes.

New SkYUVASpec more clearly defines chroma subsampling and siting of
the planes.

The intent is to use this for other YUVA APIs as well, in particular
SkImage factories in the future.

In this change we convert to the SkYUVASpec to SkYUVASizeInfo
and SkYUVAIndex[4] representation. But the intent is to use
the SkYUVASpec representation throughout the pipeline once
legacy APIs are removed.

orientation GM is replicated to test a variety of chroma
subsampling configs.

Bug: b/135133301

Follow-on to 196f319b.

- Add SkCodec::getICCProfile to match the SkAndroidCodec version.
- Update comments on getPixels() regarding how the SkColorSpace on the
SkImageInfo is treated.
- Add two new images that have ICC profiles that do not map to an
SkColorSpace. Add a test to verify that they have the un-transformed
color we expect.
- Stop uploading ColorCodecSrc images decoded to a null SkColorSpace to
Gold. Though they may be correct, they do not match other images they're
compared against. The new test above verifies that we do not do color
conversion with a null SkColorSpace.

   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always

cb6b8848de Fix uninitialized bug in SkWuffsCodec for incomplete images
Bug: skia:8579

Zero-initialize the pixel buffer that wuffs uses inside the frame rect.
If the encoded image is incomplete, we will swizzle this memory into the
destination, so this prevents swizzling uninitialized memory.

In addition, zero-initialize the client's memory if the above buffer
will not fill it, and if the frame is independent.

Move decodeFrameConfig into onStartIncrementalDecode. This makes it
clear that we haven't begun decoding the pixels so rowsDecoded is
irrelevant. Update the documentation for onStartIncrementalDecode to
make it clear that it can be called more than once (and when to do so).

If a frame is incomplete and depends on prior frames, do not blend it.
This will overwrite pixels from the prior frames without a way to undo.
Current clients only want to show incomplete images for the first frame
anyway.

Add some debugging information to Codec_partialAnim test, including
writing out pngs when failing the test.

9b0ba2c2cd SkWuffsCodec: fix dependent frames
SkWuffsCodec tells wuffs to decode only the current frame's
contribution, and then SkWuffsCodec blends it onto the prior frame (if
any). If there is a prior frame, do not call SkSampler::Fill, and blend
the new frame onto the old, rather than replacing it.

In addition, set rowsDecoded to scaledHeight to work properly for
scaled decodes.

712476ecdb Remove SkCodec::fSrcInfo
This object is now redundant with fEncodedInfo. It holds an
SkColorSpace, which is never used now that SkCodec uses skcms.

SkCodec::getInfo() no longer returns a reference, but creates an
SkImageInfo from the SkEncodedInfo the same way fSrcInfo was
previously created.

Add SkCodec::bounds() and ::dimensions() to replace calling these
methods on getInfo().

Remove srcInfo from SkMaskSwizzler::Create, which just wants to know
whether the src is opaque.

Remove the srcColorType from conversionSupported. Only the base class
version used it. Make it look at fEncodedInfo.color() instead.

81886e8f94 Switch SkCodec to use skcms
Bug: skia:6839
Bug: skia:8052

Create an skcms_Profile instead of an SkColorSpace when creating an
SkCodec. Eventually we'll move the SkImageInfo (and its SkColorSpace)
entirely to clients (e.g. SkAndroidCodec, SkCodecImageGenerator), but
for now, create it with SkEncodedInfo::makeImageInfo.

Create new SkEncodedInfo::Colors for the special PNG cases that we
want to map to specific SkColorTypes.

SkEncodedInfo:
- Add ICCProfile, which owns an skcms_ICCProfile
 - FIXME: maybe we should have a single instance for
  SRGB like SkColorSpace?
- Add kXAlpha_Color, for kAlpha_8. Since I'm not longer creating
  an SkImageInfo (at least in SkPngCodec), it needs a way to pass
  this info to the caller.
- Add k565_Color, for the same reason. Matt originally had this in
  https://codereview.chromium.org/2212563003/#ps120001, but didn't
  land that version. I like it though. Mike didn't like the bits
  per component for 565, but it seems like a sensible hack, much
  like the existing one for kAlpha_8
- Add width and height. These were removed for redundancy with
  SkImageInfo, but it makes sense to have them here without it.
BUILD.gn:
- Build the new SkEncodedInfo.cpp
SkCodec:
- Remove the constructor with an SkImageInfo. Edit the other one
  to drop width and height (now in SkEncodedInfo) and take a RHS
  reference to SkEncodedInfo
- Create the SkImageInfo from fEncodedInfo (for now)
- Consolidate choosing skcms_AlphaFormat for Transform here
- Call conversionSupported from initializeColorXform, with a new
  parameter for whether there is a color Xform, allowing SkJpegCodec
  and SkHeifCodec to override that method instead of having another
  method.
SkBmpCodec (etc)
- Adapt to the changes above
- Create a new SkEncodedInfo w/o profile for the swizzler.
SkPngCodec:
- use the new SkEncodedInfo::Colors rather than a custom SkImageInfo
SkRawCodec:
- Remove SkEncodedInfo from SkDngImage, which doesn't actually need it.
  This is helpful since we don't know all the info yet.
- Rewrite gAdobeRGB_toXYZD50 as an skcms_Matrix3x3
SkWebpCodec:
- Remove premul_step computation, and simplify to just rely on
  the base class' handling of applying the transform.
SkSwizzler:
- Add cases for the new SkEncodedInfo::Colors

e643a9ef52 SkCodec: Always use 0 for filling
This is a behavior change and a simplification.

When an image is incomplete or subset, we fill the remaining/all rows
with the fill color. A virtual method chose the fill color. Here were
the implementations:
- SkGifCodec:
Use transparent. This was changed previously to match Chromium.
- SkPngCodec/SkBmpStandardCodec:
Use the first color in the color table. This made sense when we had to
support kIndex_8, when we had to use an index from the color table.
Using that color for other types ensured that the image looked the same
in e.g. kN32 as kIndex_8. Removing this arbitrary choice simplifies the
code and moves the behavior toward Chromium's.
- SkCodec (default):
Use black for opaque images and transparent for images with alpha. A
theoretical advantage to this decision was that an incomplete image
would look the same in k565 and kN32. I don't think this is a good
enough reason to behave differently from Chromium.

Consolidate them all to just use 0. This results in transparent where
that is something we can specify. For 565 and Gray, this results in
black.

Only change to include headers is the removal of protected methods.

b62f50cf76 Replace nearly all kRespect with kIgnore
- 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).

This partially reverts commit

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.

1793e7bb46 Revert "Hide SkEncodedInfo"
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.
