Remarks
Property getter documentation:
Return whether the Bitmap will have unpremultiplied pixels.
Java documentation for android.graphics.ImageDecoder.isUnpremultipliedRequired().
Property setter documentation:
Specify whether the Bitmap should have unpremultiplied pixels.
By default, ImageDecoder will create a Bitmap with premultiplied pixels, which is required for drawing with the android.view.View system (i.e. to a Canvas). Calling this method with a value of true will result in #decodeBitmap returning a Bitmap with unpremultiplied pixels. See Bitmap#isPremultiplied Bitmap.isPremultiplied(). This is incompatible with #decodeDrawable decodeDrawable; attempting to decode an unpremultiplied Drawable will throw an java.lang.IllegalStateException.
Like all setters on ImageDecoder, this must be called inside OnHeaderDecodedListener#onHeaderDecoded onHeaderDecoded.
