Class BMPImageReader

  • All Implemented Interfaces:
    BMPConstants
    public class BMPImageReader
extends javax.imageio.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).
