Method Detail

• getAnimatedImageResult

   abstract AnimatedImageResult getAnimatedImageResult()

  Gets the original result of the decode.

• getDurationMs

   abstract int getDurationMs()

  Gets the duration of the animation.

• getFrameCount

   abstract int getFrameCount()

  Gets the number of frames in the animation.

• getLoopCount

   abstract int getLoopCount()

  Gets the number of loops to run the animation for.

• getWidth

   abstract int getWidth()

  Gets the width of the image.

• getHeight

   abstract int getHeight()

  Gets the height of the image.

• getRenderedWidth

   abstract int getRenderedWidth()

  Gets the rendered width of the image. This may be smaller than the underlying image width ifthe image is being rendered to a small bounds or to reduce memory requirements.

• getRenderedHeight

   abstract int getRenderedHeight()

  Gets the rendered height of the image. This may be smaller than the underlying image height ifthe image is being rendered to a small bounds or to reduce memory requirements.

• getFrameInfo

   abstract AnimatedDrawableFrameInfo getFrameInfo(int frameNumber)

  Gets info about the specified frame.

  Parameters:

  frameNumber - the frame number (0-based)

• renderFrame

   abstract void renderFrame(int frameNumber, Canvas canvas)

  Renders the specified frame onto the canvas.

  Parameters:

  frameNumber - the frame number (0-based)

  canvas - the canvas to render onto

• renderDeltas

   abstract void renderDeltas(int frameNumber, Canvas canvas)

  Renders the specified frame onto the canvas. The idea is the same than renderFrame(...) withthis differences: 1) Creates a new bitmap on each call. This allows to not block threads. 2)Blend is applied here

  Parameters:

  frameNumber - the frame number (0-based)

  canvas - the canvas to render onto

• getFrameForTimestampMs

   abstract int getFrameForTimestampMs(int timestampMs)

  Gets the frame index for specified timestamp.

  Parameters:

  timestampMs - the timestamp

• getTimestampMsForFrame

   abstract int getTimestampMsForFrame(int frameNumber)

  Gets the timestamp relative to the first frame that this frame number starts at.

  Parameters:

  frameNumber - the frame number

• getDurationMsForFrame

   abstract int getDurationMsForFrame(int frameNumber)

  Gets the duration of the specified frame.

  Parameters:

  frameNumber - the frame number

• getFrameForPreview

   abstract int getFrameForPreview()

  Gets the frame number to use for the preview frame.

• forNewBounds

   abstract AnimatedDrawableBackend forNewBounds(@Nullable() Rect bounds)

  Creates a new AnimatedDrawableBackend with the same parameters but with a new bounds.

  Parameters:

  bounds - the bounds

• getMemoryUsage

   abstract int getMemoryUsage()

  Gets the number of bytes currently used by the backend for caching (for debugging)

• getPreDecodedFrame

  @Nullable() abstract CloseableReference<Bitmap> getPreDecodedFrame(int frameNumber)

  Gets a pre-decoded frame. This will only return non-null if the {@code ImageDecodeOptions} wereconfigured to decode all frames at decode time.

  Parameters:

  frameNumber - the index of the frame to get

• hasPreDecodedFrame

   abstract boolean hasPreDecodedFrame(int frameNumber)

  Gets whether it has the decoded frame. This will only return true if the {@code * ImageDecodeOptions} were configured to decode all frames at decode time.

  Parameters:

  frameNumber - the index of the frame to get

• dropCaches

   abstract void dropCaches()

  Instructs the backend to drop its caches.
