Source

abstract class Source

kotlin.Any
↳	android.graphics.ImageDecoder.Source

Source of encoded image data.

References the data that will be used to decode a Drawable or Bitmap in decodeDrawable or decodeBitmap. Constructing a Source (with one of the overloads of createSource) can be done on any thread because the construction simply captures values. The real work is done in decodeDrawable or decodeBitmap.

A Source object can be reused to create multiple versions of the same image. For example, to decode a full size image and its thumbnail, the same Source can be used once with no OnHeaderDecodedListener and once with an implementation of OnHeaderDecodedListener#onHeaderDecoded that calls setTargetSize with smaller dimensions. One Source can even be used simultaneously in multiple threads.
