Examples of javax.imageio.IIOImage

javax.imageio.IIOImage
A simple container class to aggregate an image, a set of thumbnail (preview) images, and an object representing metadata associated with the image.
The image data may take the form of either a RenderedImage, or a Raster. Reader methods that return an IIOImage will always return a BufferedImage using the RenderedImage reference. Writer methods that accept an IIOImage will always accept a RenderedImage, and may optionally accept a Raster.
Exactly one of getRenderedImage and getRaster will return a non-null value. Subclasses are responsible for ensuring this behavior. @see ImageReader#readAll(int,ImageReadParam) @see ImageReader#readAll(java.util.Iterator) @see ImageWriter#write(javax.imageio.metadata.IIOMetadata,IIOImage,ImageWriteParam) @see ImageWriter#write(IIOImage) @see ImageWriter#writeToSequence(IIOImage,ImageWriteParam) @see ImageWriter#writeInsert(int,IIOImage,ImageWriteParam)
