ImageDecoder.Source Class

Definition

Source of encoded image data.

[<Android.Runtime.Register("android/graphics/ImageDecoder$Source", ApiSince=28, DoNotGenerateAcw=true)>]

Remarks

Source of encoded image data.

References the data that will be used to decode a Drawable or Bitmap in #decodeDrawable decodeDrawable or #decodeBitmap 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 decodeDrawable or #decodeBitmap 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 OnHeaderDecodedListener and once with an implementation of OnHeaderDecodedListener#onHeaderDecoded onHeaderDecoded that calls #setTargetSize with smaller dimensions. One Source can even be used simultaneously in multiple threads.
