org.apache.flex.forks.batik.ext.awt.image.codec.tiff.TIFFEncodeParam

An instance of ImageEncodeParam for encoding images in the TIFF format.

This class allows for the specification of encoding parameters. By default, the image is encoded without any compression, and is written out consisting of strips, not tiles. The particular compression scheme to be used can be specified by using the setCompression() method. The compression scheme specified will be honored only if it is compatible with the type of image being written out. For example, Group3 and Group4 compressions can only be used with Bilevel images. Writing of tiled TIFF images can be enabled by calling the setWriteTiled() method.

This class is not a committed part of the JAI API. It may be removed or changed in future releases of JAI.
