| android.graphics.ImageDecoder.OnPartialImageListener |
Interface for inspecting a DecodeException
and potentially preventing it from being thrown.

public abstract boolean onPartialImage (ImageDecoder.DecodeException exception)
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.
| Parameters | |
|---|---|
exception |
ImageDecoder.DecodeException: exception containing information about the
decode interruption.
This value cannot be null. |
| Returns | |
|---|---|
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. |
