Document

Returns a specifier for an interleaved image format that will use a ComponentColorModel and a PixelInterleavedSampleModel to store each pixel component in a separate byte, short, or int.

Usage

From source file:nitf.imageio.NITFReader.java

@Override
public Iterator<ImageTypeSpecifier> getImageTypes(int imageIndex) throws IOException {
    checkIndex(imageIndex);/*from ww  w  . j a va  2s  .c om*/
