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.

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.
