|Constructor and Description|
|Modifier and Type||Method and Description|
Returns a decoded bitmap for a given resource and target dimensions.
Returns some unique String id that distinguishes this decoder from any other decoder.
public VideoBitmapDecoder(int frame)
public Bitmap decode(ParcelFileDescriptor resource, BitmapPool bitmapPool, int outWidth, int outHeight, DecodeFormat decodeFormat) throws IOException
resource- The resource to decode, managed by the caller, no need to clean it up.
bitmapPool- A bitmap pool that can be used to reuse bitmaps during the load. Any bitmaps created or obtained from the pool other than the bitmap returned by this method should be returned to the pool.
outWidth- The target width for the returned bitmap (need not match exactly).
outHeight- The target height for the returned bitmap (need not match exactly).
decodeFormat- The desired configuration for the returned bitmap.
public String getId()
This method can return the empty string if for all practical purposes it applies no transformations to the
data while loading the resource. For
Bitmaps this would mean at a minimum doing no
downsampling and also probably always producing
Bitmap.Config.ARGB_8888 as their config.
