45
Jim Van Verth351c9b52020-11-12 15:21:11 -050046 * Added a new interface for GrDirectContext creation in Metal, using
47 a new struct called GrMtlBackendContext. The previous interface taking
48 a MTLDevice and MTLCommandQueue is deprecated.
49 https://review.skia.org/334426
50
Robert Phillipsca924242020-11-30 08:32:38 -050051 * SkCanvas::flush has been deprecated.

Heather Miller481ff132020-08-20 15:59:08 -040057
Brian Salomone4387382020-11-11 16:34:19 -050058 * SkYUVAInfo now has separate enums for division of channels among planes and
59 the subsampling. The previous combined enum, PlanarConfig, is deprecated.
60 https://review.skia.org/334102
61
Brian Salomonf1432742020-11-09 15:40:27 -050062 * Simplified SkDeferredDisplayListRecorder promise image API. Removed "release"
63 callback and renamed "done" callback to "release". The new "release" proc can
Brian Salomonbd3792d2020-11-10 14:17:58 -050064 be null. Added a new SkYUVAInfo-based factory for YUVA promise texture images
65 and deprecated the old SkYUVAIndex-based one.

Brian Osmanb06301e2020-11-06 11:45:36 -050069 * Limit the types and intrinsics supported in SkRuntimeEffect to GLSL ES 1.00
70 https://review.skia.org/332597
71
Vignesh Venkatasubramanianeb7f9602020-11-04 14:13:39 -080072 * Add AVIF support to SkHeifCodec.
73
Greg Daniel007d97d2020-11-04 10:50:39 -050074 * Add support for creating SkSurfaceCharacterizations directly for use by a
75 GrVkSecondaryCBDrawContext.
76 https://review.skia.org/331877
77
Ben Wagner9abf7192020-10-23 11:29:03 -040078 * Removed SkSurfaceProps::kLegacyFontHost_InitType, SkFontLCDConfig, and related code.
79 The default pixel geometry for SkSurfaceProps is now kUnknown instead of kRGB_H.
80 The removal was guarded by the SK_LEGACY_SURFACE_PROPS build flag which was later removed.
81 https://review.skia.org/322490
82 https://review.skia.org/329364
83
Brian Salomon9f8ee0d2020-10-19 13:31:49 -040084 * Legacy 8-bit YUV interface removed from SkImageGenerator. Use more flexible SkYUVAPixmaps-
85 based interface instead.
86 https://review.skia.org/327917
87
Brian Salomonc1a249d2020-10-19 10:55:45 -040088 * New variant of SkImage::MakeFromYUVATextures. Takes a new type GrYUVATextures
89 which wraps an SkYUVAInfo and compatible set of GrBackendTextures. The provides
90 a more complete and structured specification of the planar configuration. Previous
91 version is deprecated.
Brian Salomon694ff172020-11-04 16:54:28 -050092 Already deprecated MakeFromYUVATexturesCopyToExternal added to replace other deprecated
93 APIs. It's not recommended that clients use this and instead use the pattern described
94 in the API comment.
Brian Salomon9f8ee0d2020-10-19 13:31:49 -040095 https://review.skia.org/317762

Brian Salomonc1a249d2020-10-19 10:55:45 -040097
kylechar97a1e672020-10-19 10:07:48 -040098 * Add field to GrContextOptions to disable mipmap support even if the backend
99 supports it.
100
Mike Klein8aa0edf2020-10-16 11:04:18 -0500101 * SkTPin() removed from public API.
102
Michael Ludwig01b93ea2020-10-09 10:45:07 -0400103 * Add new SkImageFilters::Blend factory function, in place of the now deprecated
104 SkImageFilters::Xfermode factory function. Behavior is identical, but name better matches
105 conventions in SkShader and SkColorFilter.
106 https://review.skia.org/324623
107
Michael Ludwigc98d5b62020-10-09 10:31:28 -0400108 * SkImageFilters::Foo() factory functions now accept SkIRect, SkRect, and optional SkIRect* or
109 SkRect*, instead of previously just the optional SkIRect*. Internally, the crop rects are stored
110 as floats to allow for fractional crops to be defined in the local coordinate system (before
111 transformation by the canvas matrix).
112 https://review.skia.org/324622
113
Michael Ludwig7d0f8532020-10-07 15:27:20 -0400114 * Add new SkImageFilters::Shader factory and deprecate SkImageFilters::Paint factory. All
115 supported/valid Paint() filters can be represented more cleanly as a Shader image filter.
116 https://review.skia.org/323680
117
Adlai Holler0ce2c542020-10-06 14:04:35 -0400118 * GrContext has been replaced by two separate classes: GrDirectContext which is
119 the traditional notion of GrContext, and GrRecordingContext which is a context
120 that is recording an SkDeferredDisplayList and therefore has reduced functionality.
121 Unless you are using SkDeferredDisplayList, migrate directly to GrDirectContext in
122 all cases.
123
Brian Salomon72c7b982020-10-06 10:07:38 -0400124 * CPU sync bool added to SkSurface::flushAndSubmit() and GrContext::flushAndSubmit()
125
Brian Salomonf165f792020-10-05 13:25:05 -0400126 * Removed legacy variant of SkImage::MakeFromYUVAPixmaps. Use the version that
127 takes SkYUVAPixmaps instead. It has a more structured description of the
128 planar configuration.
129 https://review.skia.org/322480
130
Brian Salomon86d07fd2020-10-02 14:37:57 -0400131 * Some SkImage YUV image factories have been removed. Replacement patterns
132 outlined below.
133 SkImage::MakeFromYUVATexturesCopy
134 1) Make SkImage from YUVA planes using SkImage::MakeFromYUVATextures
135 2) Use Skia to allocate a surface using SkSurface::MakeRenderTarget
136 3) surface->getCanvas()->drawImage(image, 0, 0);
137 4) surface->makeImageSnapShot() produces RGBA image.
138 SkImage::MakeFromYUVATexturesCopyWithExternalBackend
139 1) Make image using MakeFromYUVATextures
140 2) Make a SkSurface around result texture using SkSurface::MakeFromBackendTexture
141 3) surface->getCanvas()->drawImage(image, 0, 0);
142 4) surface->flushAndSubmit()
143 5) Optional: SkImage::MakeFromBackendTexture() to use as SkImage.
144 SkImage::MakeFromNV12TexturesCopy
145 Same as SkImage::MakeFromYUVATexturesCopy
146 https://review.skia.org/321537
147
Greg Daniel36366202020-10-02 11:13:33 -0400148 * GrBackendRenderTargets which are created with a stencilBits param, now require
149 the stencilBits to be 0, 8, or 16.

155------------
156
Brian Salomon57fd9232020-09-28 17:02:49 -0400157 * GrVkImageInfo now has a field for sample count. GrBackendRenderTarget constructor
158 that took both a GrVkImageInfo and separate sample count is deprecated. Use the
Brian Salomon718ae762020-09-29 16:52:49 -0400159 version without sample count instead. Similarly, GrD3DTextureResourceInfo now
160 has a sample count field and GrBackendRenderTarget no longer takes a separate
Brian Salomon8e0aa442020-09-30 13:50:18 -0400161 sample count for Direct3D. The sample count for GrBackendRenderTarget is now
162 directly queried from MtlTexture rather than passed separately. The version that
163 takes a separate sample count is deprecated and the parameter is ignored.

169 https://review.skia.org/320260
170
Brian Salomon57fd9232020-09-28 17:02:49 -0400171 * GrVkImageInfo now has a field for sample count. GrBackendRenderTarget constructor
172 that took both a GrVkImageInfo and separate sample count is deprecated. Use the
173 version without sample count instead.
174
Michael Ludwige5d5eed2020-09-28 10:33:42 -0400175 * Update SkClipOp::kMax_EnumValue to include only intersect and difference when
176 SK_SUPPORT_DEPRECATED_CLIPOPS is not defined.
177 https://review.skia.org/320064
178
Jim Van Verth1b89eb72020-09-23 16:29:51 -0400179 * Add support for external allocator for Direct3D 12 backend.
180 Defines base classes for an allocation associated with a backend texture and a
181 a memory allocator to create such allocations.
182 Adds memory allocator to backend context.
183 https://review.skia.org/317243
184
Greg Daniel1d3c8c12020-09-23 14:23:36 -0400185 * Add new optional parameter to GrContext::setBackend[Texture/RenderTarget]State which can
186 be used to return the previous GrBackendSurfaceMutableState before the requested change.
187 https://review.skia.org/318698
188
Michael Ludwig395ddc32020-09-16 18:41:38 +0000189 * New optimized clip stack for GPU backends. Enabled by default but old behavior based on
190 SkClipStack can be restored by defining SK_DISABLE_NEW_GR_CLIP_STACK when building. It is not
191 compatible with SK_SUPPORT_DEPRECATED_CLIPOPS and we are targeting the removal of support for
192 the deprecated, expanding clip ops.
193 https://review.skia.org/317209
194
John Stilesf2f9b0d2020-08-25 13:33:45 -0400195 * GPU backends now properly honor the SkFilterQuality when calling drawAtlas.
196 https://review.skia.org/313081
197
Brian Osman767f4442020-08-13 16:59:48 -0400198 * The signature of 'main' used with SkRuntimeEffect SkSL has changed. There is no longer an
199 'inout half4 color' parameter, effects must return their color instead.
200 Valid signatures are now 'half4 main()' or 'half4 main(float2 coord)'.
201 https://review.skia.org/310756
202
Brian Salomon94f65d72020-09-18 14:09:51 -0400203 * New YUVA planar specifications for SkCodec, SkImageGenerator, SkImage::MakeFromYUVAPixmaps.
204 Chroma subsampling is specified in more structured way. SkCodec and SkImageGenerator
205 don't assume 3 planes with 8bit planar values. Old APIs are deprecated.

Brian Osmana4b91692020-08-10 14:26:16 -0400219 * Remove support for 'in' variables from SkRuntimeEffect. API now exclusively refers to inputs
220 as 'uniforms'.

233
Brian Salomon7e67dca2020-07-21 09:27:25 -0400234 * Rename GrMipMapped to GrMipmapped for consistency with new APIs.
Brian Salomon40a40622020-07-21 10:32:07 -0400235 Also rename GrBackendTexture::hasMipMaps() to GrBackendTexture::hasMipmaps()

244
Greg Danielc72d7a52020-06-25 21:00:17 -0400245 * Adds default flush() calls to SkSurface, SkImage, and GrContext. These calls do
Greg Danielce9f0162020-06-30 13:42:46 -0400246 a basic flush without a submit. If you haven't updated Skia in a couple releases
Greg Danielc72d7a52020-06-25 21:00:17 -0400247 and still have flush() calls in your code that you expect to do a flush and
248 submit, you should update all those to the previously added flushAndSubmit() calls
249 instead.

Robert Phillips2a4acf32020-07-06 15:50:15 -0400258 * Ganesh is moving towards replacing GrContext with the GrDirectContext/GrRecordingContext
259 pair. GrDirectContexts have _direct_ access to the GPU and are very similar to the old
260 GrContext. GrRecordingContexts are less powerful contexts that lack GPU access but provided
261 context-like utilities during DDL recording. SkSurfaces and SkCanvas will now only return
262 GrRecordingContexts. Clients requiring context features that need GPU access can then
263 check (via GrRecordingContext::asDirectContext) if the available recording context is actually
264 a direct context.
265
John Stiles91196252020-07-28 09:23:54 -0400266 * Replace #defined values in SkString with equivalent constexprs.

Kevin Lubick23620222020-06-03 11:19:49 -0400301 * SkCanvas.clear and SkCanvas.drawColor now accept SkColor4f in addition to SkColor.
302
Brian Salomonc0d88a12020-05-28 17:44:05 -0400303 * Remove SkSurface::MakeFromBackendTextureAsRenderTarget.
304 This factory existed to work around issues with GL_TEXTURE_RECTANGLE that existed
305 in Chrome's command buffer. Those issues have since been resolved. Use
306 SkSurface::MakeFromBackendTexutre or SkSurface::MakeFromBackendRenderTarget instead.

Greg Daniel55822f12020-05-26 11:26:45 -0400309 * Adds submittedProc callback to GrFlushInfo which will be called when the work
310 from the flush call is submitted to the GPU. This is specifically useful for knowing
311 when semahpores sent with the flush have been submitted and can be waiting on.

313
Greg Daniel04283f32020-05-20 13:16:00 -0400314 * GrContext submit is now required to be called in order to send GPU work to the
315 actual GPU. The flush calls simply produces 3D API specific objects that are ready
316 to be submitted (e.g. command buffers). For the GL backend, the flush will still
317 send commands to the driver. However, clients should still assume the must call
318 submit which is where any glFlush that is need for sync objects will be called. There,
319 are flushAndSubmit() functions of GrContext, SkSurface, and SkImage that will act
320 like the previous flush() functions. This will flush the work and immediately call
321 submit.

329 patch cubic positions) will be directly used to sample the SkShader.

349 guarantee that all the data has been uploaded and the gpu is done with the texture.
350 Instead the client can assume the upload work has been submitted to the gpu and they
351 must wait for that work to finish before deleting the texture. This can be done via
352 their own synchronization or by passing in a finish proc into the create calls which
353 will be called when it is safe to delete the texture (at least in terms of work
354 done during the create).

359
Xianzhu Wanga91e4782020-05-01 09:34:57 -0700360 * Add back SkCanvas::kPreserveLCDText_SaveLayerFlag to indicate that saveLayer()

362 to ensure correct rendering.
363
Leon Scroggins III63cfb362020-04-24 13:00:48 -0400364 * Add the new directory client_utils/ for code that is specific to a single client and

366 subdir android/.
367
Mike Kleind5cba9d2020-04-24 07:44:50 -0500368 * SkBitmap and SkPixmap's erase() methods now treat their color parameters
369 consistently with the rest of Skia, with all SkColors and any untagged
370 SkColor4fs interpreted as sRGB, not as a color in the bitmap's color space.
371 SkPixmap::erase(SkColor4f) now takes an SkColorSpace, so you can pass
372 pixmap.colorSpace() if you want the old behavior.

Ben Wagnercc81e202020-04-09 13:00:44 -0400377 * Changed Dilate and Erode image filters to take SkScalar for radius instead of int. While
378 the image filters themselves are defined in terms of discrete pixels, the radii provided by
379 the user are mapped through the CTM so taking ints forced over discretization. After mapping
380 through the CTM the radii are now rounded to pixels.

385 clear that the caller is responsible for deleting any initialized semaphores after the flush
386 call regardless if we were able to submit them or not. Also, allows skia to only submit a

418 SkCanvas automatically wrap the bitmap in an SkImage and call the equivalent drawImage function.
419 Drawing mutable SkBitmaps will now incur a mandatory copy. Switch to using SkImage directly or

492 the GPU doesn't support the specified compression type (i.e., macOS Metal
493 doesn't support BC1_RGB8_UNORM so such compressed images will always be

591 https://review.skia.org/244676
592
593 * Add explicit src and dst colorspace parameters to SkColorFilter::filterColor4f()
594 https://review.skia.org/244882
595
596 * Remove Vulkan/Metal float32 RGBA texture support
597 https://review.skia.org/244881
598
599 * Add SkSurface::MakeFromCAMetalLayer
600 https://review.skia.org/242563
601
602 * Added kAlpha_F16_SkColorType, kRG_F16_SkColorType and kRGBA_16161616_SkColorType.
603 This is intended to help support HDR YUV uses case (e.g., P010 and P016). As such,
604 the addition is focused on allowing creation of SkPixmaps and SkImages and not
605 SkSurfaces (i.e., who wants to render to render to these?)
606 https://review.skia.org/241357
607
608 * Start to move nested SkPath types (e.g. Direction, Verb) up to root level in SkPathTypes.h
609 https://review.skia.org/241079
610
611 * Remove isRectContour and ksNestedFillRects from public
612 https://review.skia.org/241078
613
614 * Added kRG_88_SkColorType. This is intended to help support YUV uses case (e.g., NV12).
615 As such, the addition is focused on allowing creation of SkPixmaps and SkImages and not
616 SkSurfaces (i.e., who wants to render to RG?)

Brian Osman172bb442019-09-06 10:16:02 -0400620 * Make the size of program/pipeline caches configurable via
621 GrContextOptions::fRuntimeProgramCacheSize
622 https://review.skia.org/239756
623
Hal Canary9e514a12019-10-01 15:15:36 -0400624 * Added kAlpha_16_SkColorType and kRG_1616_SkColorType. This is intended to help support HDR YUV
625 uses case (e.g., P010 and P016). As such, the addition is focused on allowing creation of
626 SkPixmaps and SkImages and not SkSurfaces (i.e., who wants to render to render to these?)
627 https://review.skia.org/239930
628
629 * Add GrContext::precompileShader to allow up-front compilation of previously-cached shaders.
