Class LegacyTiffForm

java.lang.Object

visad.data.FormNode

visad.data.Form

visad.data.tiff.LegacyTiffForm

All Implemented Interfaces:

FormBlockReader, FormFileInformer, FormProgressInformer

Deprecated.

Use TiffForm, or visad.data.bio.LociForm with loci.formats.in.TiffReader and loci.formats.out.TiffWriter

public class LegacyTiffForm
extends Form
implements FormFileInformer, FormBlockReader, FormProgressInformer

LegacyTiffForm is the old VisAD data form for the TIFF file format. It relies on either ImageJ or JAI being available in the class path, and is very inefficient when dealing with large multi-page TIFF files. The following table indicates features that the form supports:

	uncompressed	compressed (LZW)
single image	read and write	read only (with JAI)
multi-page	read and write	read only (with JAI)

This form requires ImageJ, available from the ImageJ web site. Note that features marked with "(with JAI)" also require the Java Advanced Imaging (JAI) package, available at Sun's Java Advanced Imaging web site. Also, no support for reading TIFF data from URLs is provided. However, the visad.data.jai package provides limited support for importing single-image TIFF data from a URL.
