List of forceComponentColorModel() Examples

Examples of forceComponentColorModel()

org.geotools.image.ImageWorker.forceComponentColorModel()
Reformats the {@linkplain ColorModel color model} to a {@linkplain ComponentColorModel component color model} preserving transparency. This isused especially in order to go from {@link PackedColorModel} to {@link ComponentColorModel}, which seems to be well accepted from {@code PNGEncoder} and {@code TIFFEncoder}.
This code is adapted from jai-interests mailing list archive. @return this {@link ImageWorker}. @see FormatDescriptor
