ImageTranscoder

public interface ImageTranscoder

The ImageTranscoder interface is to be implemented by classes that perform image transcoding operations, that is, take images written in one format and write them in another format using read/write operations. Some image data can be lost in such processes. The ImageTranscoder interface converts metadata objects (IIOMetadata) of ImageReader to appropriate metadata object for ImageWriter.

since: Android 1.0
