Property Value

Attributes

Remarks

Property getter documentation:

Return whether the decoded Bitmap will be mutable.

Java documentation for android.graphics.ImageDecoder.isMutableRequired().

Property setter documentation:

Specify whether the Bitmap should be mutable.

By default, a Bitmap created by #decodeBitmap decodeBitmap will be immutable i.e. Bitmap#isMutable() Bitmap.isMutable() returns false. This can be changed with setMutableRequired(true).

Mutable Bitmaps are incompatible with #ALLOCATOR_HARDWARE, because Bitmap.Config#HARDWARE Bitmaps cannot be mutable. Attempting to combine them will throw an java.lang.IllegalStateException.

Mutable Bitmaps are also incompatible with #decodeDrawable decodeDrawable, which would require retrieving the Bitmap from the returned Drawable in order to modify. Attempting to decode a mutable Drawable will throw an java.lang.IllegalStateException.

Like all setters on ImageDecoder, this must be called inside OnHeaderDecodedListener#onHeaderDecoded onHeaderDecoded.
