Methods

Modifier and Type	Method and Description

Method Detail

decode

Bitmap decode(T resource,
            BitmapPool bitmapPool,
            int outWidth,
            int outHeight,
            DecodeFormat decodeFormat)
              throws Exception

Returns a decoded bitmap for a given resource and target dimensions.

Parameters:

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.

Throws:

Exception

getId

String getId()

Returns some unique String id that distinguishes this decoder from any other decoder.

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 Bitmaps with Bitmap.Config.ARGB_8888 as their config.
