Graphics Shapes Version 1.0

Version 1.0.0-alpha03

June 7, 2023

androidx.graphics:graphics-shapes:1.0.0-alpha03 is released. Version 1.0.0-alpha03 contains these commits.

API Changes

• Added new RoundedPolygon.rectangle() function (I78e7e, b/280322189)
• Star and Circle functions are now decapitalized and called via RoundedPolygon's companion object: e.g., RoundedPolygon.star(...)(I14735)

Bug Fixes

• Fixed bug on smoothing (Ibf894)
• Fixed a bug that occured when start and end shape were the same. Better distribute available space on side for cuts, first using available space for rounding, then for smoothing if there is space left. (Ibd320, b/277936300)

Version 1.0.0-alpha02

April 19, 2023

androidx.graphics:graphics-shapes:1.0.0-alpha02 is released. Version 1.0.0-alpha02 contains these commits.

API Changes

• The Polygon superclass was merged in with its subclass, RoundedPolygon; all polygons are now [optionally] rounded polygons.
• The Star function (which still returns a RoundedPolygon, as before) now takes an innerRadius value, instead of the previous innerRadiusRatio parameter. This is in the same units as the existing radius parameter, making things simpler and more consistent. Also, the numOuterVertices parameter was renamed to numVerticesPerRadius to clarify that the same number is applied to both inner and outer radii.
• CornerRounding.radius was previously documented to be relative to the size of the polygon, but it was (and should be) an absolute, not relative, value. The docs were updated and the annotation limiting it to a max value of 1.0 was fixed.

Version 1.0.0-alpha01

April 5, 2023

Graphics-Shapes is a new library which allows easy creation and rendering of rounded polygonal shapes, as well as simple and automatic morphing (animation) between different shapes.

androidx.graphics:graphics-shapes:1.0.0-alpha01 is released. This version was released from an internal branch.

New Features

• Use the Polygon API to create regular and star polygons with the desired number of vertices.
• Use optional CornerRounding parameters to specify the rounding radius and smoothing parameters for the corners, resulting in polygonal shapes with rounded corners.
• Use the new Morph(Polygon, Polygon) API to automatically calculate a “morph” shape whose progress can be set from 0 to 1 to animate between the starting and ending shapes. Animate that progress over time, drawing the result on every frame, to create a smooth animation between these new rounded shapes.

Graphics Path Version 1.0

Version 1.0.0-alpha02

June 7, 2023

androidx.graphics:graphics-path:1.0.0-alpha02 is released. This version is developed in an internal branch.

New Features

• Fixed problem with internal platform version check which caused problems when running on Android 14 previews (the version check would fail, but the mechanism for doing things on previous releases doesn’t work correctly on Android 14 in particular).

Version 1.0.0-alpha01

March 22, 2023

androidx.graphics:graphics-path:1.0.0-alpha01 is released. Version 1.0.0-alpha01 contains these commits.

New Features

• This new library allows querying of Path data via the new PathIterator API. Using this API, callers can iterate through all segments of a Path object to determine the operation and data for those segments.
• The library uses similar APIs introduced in Android 14 preview, but this AndroidX version of the API also works on versions back to API 21.

Graphics Core Version 1.0

Version 1.0.0-alpha05

September 6, 2023

androidx.graphics:graphics-core:1.0.0-alpha05 is released. Version 1.0.0-alpha05 contains these commits.

New Features

• Introduced GLFrameBufferRenderer API. This provides a combination of OpenGL dependencies, swap chain configuration, pixel formats and SurfaceControl configuration. (Ic775b)

API Changes

• Added width + height parameters to various callback APIs to pipe dimensions from SurfaceHolder#Callbacks. (I7f9fc)
• Added clear API to clear both front and multi buffered layers. (Ic1f95)
• Added support to configure the underlying buffer type of swapchains used within GLFrontBufferedRenderer. (I07a13)
• Added kotlin properties for getters on GLFrameBufferRenderer, IntRange annotation for max buffer entries, and HardwareBufferFormart and HardwareBufferUsage annotations for setFormat/setUsage respectively. (Ief89e)
• Updated setBuffer API on SurfaceControl transactions to provide a release fence. (Ice1bb)
• Added SurfaceControlCompat.Transaction APIs to configure the data space as well as set the extended brightness range. (Ic378d)

Version 1.0.0-alpha04

June 7, 2023

androidx.graphics:graphics-core:1.0.0-alpha04 is released. Version 1.0.0-alpha04 contains these commits.

New Features

• Introduced CanvasFrontBufferedRenderer to support low latency graphics leveraging the android.graphics.Canvas API alongside the existing OpenGL implementation

API Changes

• Updated SurfaceControlCompat.Transaction#setBuffer API to allow for nullable HardwareBuffer instances to mirror the corresponding platform API (I173d7)
• Rename methods referring to Double Buffered rendering to Multi Buffered instead as the backing swapchain may contain more than 2 buffers. (I830d7)
• Create CanvasFrontBufferedRenderer API to enable 3ps to leverage a front buffered rendering system using the Canvas API. (Ibfc29)

Bug Fixes

• Fixed issue where GLFrontBufferedRenderer would not render content after resuming the corresponding Activity.
• Fixed issue where front buffered content would be cleared prematurely.
• Fixed issue where SurfaceHolder.Callbacks would not be removed after low latency graphics APIs were released.

Version 1.0.0-alpha03

March 22, 2023

androidx.graphics:graphics-core:1.0.0-alpha03 is released. Version 1.0.0-alpha03 contains these commits.

API Changes

• Updated GLFrontBufferedRenderer callback implementation to provide BufferInfo object that contains buffer width/height along with a frame buffer identifier that can be used to re-target the original destination after rendering to an intermediate scratch buffer. (I7fe20)
• Consolidated SyncFence creation to static factory method on SyncFenceCompat.
• Removed public compatibility method for eglDupNativeFenceFDANDROID in favor of SyncFenceCompat factory method for SyncFence creation. This is to ensure all API surfaces receive the correct SyncFence implementation regardless of API level. (I849bb)
• Added documentation for FrameBufferRenderer and SyncStrategy.
  • Moved FrameBufferRenderer + FrameBuffer + FrameBufferPool to androidx.graphics.opengl package
  • Moved SyncStrategy to androidx.graphics.opengl package
  • Updated RenderCallback#onDraw docs
  • Updated documentation of RenderCallback#obtainFrameBuffer that implementor of API is responsible for calling FrameBuffer.close
  • Updated onDrawComplete to indicate consumers are responsible for dispatching contents to display
  • Moved SyncFence compatibility interfaces/classes to androidx.hardware package to mirror the framework
  • Renamed SyncFence API to SyncFenceV19 and made private to consolidate usages to SyncFenceCompat which leverages the framework's SyncFence API wherever possible. (I5149c)
• Added GLFrontBufferedRenderer#cancel and GLFrontBufferedRenderer#execute methods. The former is useful in palm rejection scenarios where rendering to the front buffer should be cancelled and hide the front buffer. The latter is useful in scenarios to manipulate objects on the GL thread without having to schedule a render. (If0b7f)
• Add API to render directly to the double buffered layer. This assists with re-rendering a scene after resume as well as giving an opportunity to consumers to selectively determine when to leverage front buffered rendering dynamically based on the desired scene to render. (Ied56c)
• Added new API to SurfaceControlCompat.Builder to support configuring the parent SurfaceControl from another SurfaceControl instance in addition to the existing mechanism from a SurfaceView. (I1d1b6)
• More return type nullability of deprecated-hidden functions (Ibf7b0)
• Added EGL_ANDROID_get_native_client_buffer extension constant to query whether the Android device supports importing of HardwareBuffer instances into EGLClientBuffer objects that can be consumed as an EGLImage instance. (Iad767)
• Adding @JvmDefaultWithCompatibility annotation (I8f206)

Version 1.0.0-alpha02

November 9, 2022

androidx.graphics:graphics-core:1.0.0-alpha02 is released. Version 1.0.0-alpha02 contains these commits.

API Changes

• Fixed missing RequiresApi annotation for addTransactionCommitListener which was introduced in Android S (I0a035)
• Updated onDraw<Front/Double> Buffer callbacks to provide a transform matrix that consumers can pass to their vertex shaders in addition to the current buffer width/height. Consumers are responsible for using these parameters to properly pre-rotate their OpenGL rendering code. (I82f9e)

Bug Fixes

• Improved graphics latency by pre-rotating buffers before issuing SurfaceControl transactions.
• Fixed issue where error logs would show error 300d (EGL_BAD_SURFACE).
• Fixed issue where GLFrontBufferedRenderer would be invalid after the corresponding Activity it was used within was resumed.
• Increased support for emulators and ChromeOS devices.
• Fixed issue where the front buffered layer maybe hidden prematurely.
