Class BMPImageReader

java.lang.Object

javax.imageio.ImageReader

com.sun.media.imageioimpl.plugins.bmp.BMPImageReader

All Implemented Interfaces:

BMPConstants

public class BMPImageReader
extends ImageReader
implements BMPConstants

This class is the Java Image IO plugin reader for BMP images. It may subsample the image, clip the image, select sub-bands, and shift the decoded image origin if the proper decoding parameter are set in the provided ImageReadParam. This class supports Microsoft Windows Bitmap Version 3-5, as well as OS/2 Bitmap Version 2.x (for single-image BMP file).
