abstract int getHeight()
Gets the height of the frame.
abstract int getWidth()
Gets the width of the frame.
abstract int getXOffset()
Gets the x-offset of the frame relative to the image canvas.
abstract int getYOffset()
Gets the y-offset of the frame relative to the image canvas.
abstract void renderFrame(int width, int height, Bitmap bitmap)

Public Methods

public abstract void dispose ()

Disposes the instance. This will free native resources held by this instance. Once called, other methods on this instance may throw. Note, the underlying native resources may not actually be freed until all associated instances AnimatedImage are disposed or finalized as well.

public abstract int getDurationMs ()

Gets the duration of the frame.

Returns
  • the duration of the frame in milliseconds

public abstract int getHeight ()

Gets the height of the frame.

Returns
  • the height of the frame

public abstract int getWidth ()

Gets the width of the frame.

Returns
  • the width of the frame

public abstract int getXOffset ()

Gets the x-offset of the frame relative to the image canvas.

Returns
  • the x-offset of the frame

public abstract int getYOffset ()

Gets the y-offset of the frame relative to the image canvas.

Returns
  • the y-offset of the frame

public abstract void renderFrame (int width, int height, Bitmap bitmap)

Renders the frame to the specified bitmap. The bitmap must have a width and height that is at least as big as the specified width and height and it must be in RGBA_8888 color format.

Parameters
width the width to render to (the image is scaled to this width)
height the height to render to (the image is scaled to this height)
bitmap the bitmap to render into
