OnPartialImageListener
interface OnPartialImageListener
| android.graphics.ImageDecoder.OnPartialImageListener |

abstract fun onPartialImage(exception: ImageDecoder.DecodeException): Boolean
Called by ImageDecoder when there is only a partial image to display.
If decoding is interrupted after having decoded a partial image, this method will be called. The implementation can inspect the DecodeException and optionally finish the rest of the decode creation process to create a partial Drawable or Bitmap.

exception |
ImageDecoder.DecodeException: exception containing information about the decode interruption. This value cannot be null. |
| Return | |
|---|---|
Boolean |
true to create and return a Drawable or Bitmap with partial data. false (which is the default) to abort the decode and throw e. Any undecoded lines in the image will be blank. |
