Class BMPDescriptor

All Implemented Interfaces:
OperationDescriptor, RegistryElementDescriptor, Serializable

public class BMPDescriptor
extends OperationDescriptorImpl

An OperationDescriptor describing the "BMP" operation.

The "BMP" operation reads a standard BMP input stream. The "BMP" operation currently reads Version2, Version3 and some of the Version 4 images, as defined in the Microsoft Windows BMP file format.

Version 4 of the BMP format allows for the specification of alpha values, gamma values and CIE colorspaces. These are not currently handled, but the relevant properties are emitted, if they are available from the BMP image file.

The classes in the package are not a committed part of the JAI API. Future releases of JAI will make use of new classes in their place. This class will change accordingly.
