Graphics Version 1.1

Version 1.1.0-alpha01

December 11, 2024

androidx.graphics:graphics-*:1.1.0-alpha01 is released. Version 1.1.0-alpha01 contains these commits.

New Features

  • Reworked the main demo into a generic Shape Editor. This allows you to import shapes from a svg path, manually edit the detected features in case of misses in the automatic process, and export the result into code that can be used in production code. (I1ac13)
  • Replace angle measurements for shape outline progress with curve length measurements, this allows more complex shapes to be used for morphing. (I75478) , I390dd
  • Improved the feature mapping algorithm, so more morphs should look more natural. (I83287)

API Changes

  • Add SVG path import and feature serializer. The usual flow is:
    • Use the new SvgPathParser.parseFeatures() to convert a svg path (the value of the d attribute on the path element of a svg) into a List<Feature>.
    • That can be modified, then serialized into a string with FeatureSerializer.serialize().
    • The resulted string can be used in production code, importing it with FeatureSerializer.parse()
    • Note that the steps 1 & 2 are done once, and can be done with the new app. Production code should only need to do step 3. (I9bd00, b/371196190), (Ic3842), (If68ed), (I10251)
  • Expose polygon features and feature types. More generic RoundedPolygons can now be created with the base constructor that takes a List<Features>. Features are mainly a list of Cubic bezier curves, but they are tagged to help the Morph algorithm match between the start and end shapes (convex corners are mapped to convex corners and concave corners are mapped to concave corners). (I61e76), (I1fc5c)
  • Adds support for watchosDeviceArm64 KMP target and target kotlin 1.9. (Icf15d, b/364652024)

Bug Fixes

  • Fixed edge case when the last feature was empty. (I390dd)
  • Make RoundedPolygon creation more robust. (Ib862c, b/360888486)
  • Fix a bug on RoundedPolygon initialization. (I83ddb)
  • Fix an error in the algorithm to estimate the center of the polygon. (Ida147)

Graphics Shapes Version 1.0

Version 1.0.0

September 4, 2024

androidx.graphics:graphics-shapes:1.0.1, androidx.graphics:graphics-shapes-android:1.0.1, and androidx.graphics:graphics-shapes-desktop:1.0.1 are released. Version 1.0.1 contains these commits.

Version 1.0.0

August 21, 2024

androidx.graphics:graphics-shapes:1.0.0, androidx.graphics:graphics-shapes-android:1.0.0, and androidx.graphics:graphics-shapes-desktop:1.0.0 are released. Version 1.0.0 contains these commits.

Version 1.0.0-rc01

July 24, 2024

androidx.graphics:graphics-shapes:1.0.0-rc01, androidx.graphics:graphics-shapes-android:1.0.0-rc01, and androidx.graphics:graphics-shapes-desktop:1.0.0-rc01 are released. Version 1.0.0-rc01 contains these commits.

Version 1.0.0-beta01

May 1, 2024

androidx.graphics:graphics-shapes:1.0.0-beta01, androidx.graphics:graphics-shapes-android:1.0.0-beta01, and androidx.graphics:graphics-shapes-desktop:1.0.0-beta01 are released. Version 1.0.0-beta01 contains these commits.

API Changes

  • Allow shapes to be pre-rotated to start at a different point. This change allows pillStar shapes to start their curves from a non-default point on the perimeter. This can be useful when animating the stroking of the shape's path, to start drawing from a specific location on the shape's outline. (Ifbb4d, b/324303807)
  • Added calculateBounds() functions to Morph, which parallel the same functions on RoundedPolygon. (I8a3b6, b/325463575)

Version 1.0.0-alpha05

February 7, 2024

androidx.graphics:graphics-shapes:1.0.0-alpha05, androidx.graphics:graphics-shapes-android:1.0.0-alpha05, and androidx.graphics:graphics-shapes-desktop:1.0.0-alpha05 are released. Version 1.0.0-alpha05 contains these commits.

New Features

  • The library now offers new pill() and pillStar() functions for easy creation of these rounded/starred shapes. There are also new APIs for calculating the exact bounds required for a shape (the previous bounds were just an estimate based on the underlying Bezier curve anchor and control points), as well as the max possible bounds, which can be helpful to determine the size of the container holding it if it will be rotated within that container. (I71827)

API Changes

Bug Fixes

  • There were occasional rendering artifacts when drawing these shapes as stroked paths, due to a low-level rendering issue related to zero-length curves. This bug was fixed by eliminating all zero-length curves (which the shapes do not need, thus also saving on the overhead of the paths produced by the shapes).

Version 1.0.0-alpha04

December 13, 2023

androidx.graphics:graphics-shapes:1.0.0-alpha04, androidx.graphics:graphics-shapes-android:1.0.0-alpha04, and androidx.graphics:graphics-shapes-desktop:1.0.0-alpha04 are released. Version 1.0.0-alpha04 contains these commits.

New Features

  • This release contains several API changes, as well as bug fixes.
  • Many of the API changes make the Shapes library KMP-friendly. This makes it easier to call from non-Android code (such as Android-agnostic Compose code). For example, there are no Android types in the API, such as the previous PointF, Matrix, and Path types.
  • There were also several changes made to APIs and implementation for performance reasons, specifically to minimize object allocation (and collection). For example, the move from PointF to separate Float parameters avoids allocating many temporary PointF structures to hold those vertices.

API Changes

  • Replaced Morph.asMutableCubics with a function to iterate over the MutableCubics. Changed PointTransformer functional interface, now it takes x and y coordinates of a Point and returns a TransformedResult (which is constructed with the transformed x & y coordinates) (I6719e)
  • Removed the public Cubic constructor and made it a factory function. (I409ce)
  • Adding Android-specific transform and drawing APIs (I079f6, b/292289543)
  • Eliminate android dependencies (Iadc1c, b/292289543)
  • Anchor and control property names are more sensible now (If13bd, b/294562941)
  • PointF parameters changed to Float pairs (Id4705, b/276466399, b/290254314)
  • progress is now passed to Morph drawing commands directly (Icdca2)

Bug Fixes

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.

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

Version 1.0.0-rc01

April 17, 2024

androidx.graphics:graphics-core:1.0.0-rc01 is released. This version is developed in an internal branch.

Bug Fixes

  • Fixed issue leading to potential double closure of file descriptors with the CanvasBufferedRendererAPI with certain Android devices running Android 14.
  • Fixed issue where FrameBuffer would not properly delete framebuffer instances.

Version 1.0.0-beta01

December 13, 2023

androidx.graphics:graphics-core:1.0.0-beta01 is released. Version 1.0.0-beta01 contains these commits.

New Features

  • Introduced a new LowLatencyCanvasView API to support low latency rendering with Android’s 2d graphics APIs (Canvas + Paint) within the View hierarchy.
  • Introduced CanvasBufferedRenderer API to support hardware accelerated Canvas rendering to a HardwareBuffer. This can be used to draw a portion of a user interface into a buffer that can be converted to a Bitmap using the Bitmap.wrapHardwareBuffer API.

API Changes

  • Updated CanvasBufferRenderer#releaseBuffer API to have an optional fence parameter. Updated documentation to describe when RenderResult#fence is returned. (If1ea7)
  • Add draw method to RenderRequest to support leveraging coroutines to schedule draw requests. Renamed the previous draw method that consumed an executor to drawAsync. Refactored isClosed() method to a property. (I5bff6)
  • Exposed buffer format parameter to CanvasFrontBufferRenderer to map directly to CanvasBufferedRenderer.Builder#setBufferFormat (I0f272)
  • Created CanvasBufferedRenderer API to handle hardware accelerated canvas rendering into a HardwareBuffer. This provides a backported implementation to Android Q alongside configuration of a swapchain depth of HardwareBuffers. ColorSpace configuration is still limited to Android U+ however the compat implementation provides no-op behavior on the developers' behalf. (I9b1d8)
  • Add setFrameRate/clearFrameRate APIs to SurfaceControlCompat.Transaction in order to control the frame rate alongside the change strategy for seamless or default transitions. (I6045c)
  • Lowered required API level for setDataSpace to Android Q from Android T. (I59c34)
  • Added onBufferReleased callback to GLFrameBufferRenderer API to give consumers the opportunity to clean up state when a buffer is no longer being presented (I8a4e2)
  • Create LowLatencyCanvasView to support a simple use case of rendering content with low latency that gets synchronized with the View hierarchy rendering. This mitigates the complexities associated with SurfaceView management by internally managing the SurfaceView instance that gets translated off/on screen for synchronized and low latency rendering respectively. (I9253b)
  • Added colorspace configuration support to CanvasFrontBufferedRenderer API. Updated multibuffered callbacks to also include the back buffered SurfaceControl (I24bd9)

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.

Version 1.0.0-alpha01

October 24, 2022

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

New Features

  • Initial release of the graphics core AndroidX library. This includes APIs to support low latency use cases such as stylus input. This also introduces some helper APIs for OpenGL usage.

API Changes

  • Introduces GLFrontBufferedRenderer to assist in front and multi-buffered rendering to achieve both low latency and high quality rendering output.
  • Introduces GLRenderer API to assist in OpenGL rendering for various Surface providers such as SurfaceView, TextureView and others.
