- * Targa image reader adapted from sources of the <a href =

- *
- * <P>
- *
- * Image decoder for image data stored in TGA file format.
- * Currently only the original TGA file format is supported. This is

- * to the end of a file in an InputStream orient environment presents
- * several difficulties which are avoided at the moment.
- *
- * <P>
- *
- * This is a simple decoder and is only setup to load a single image
- * from the input stream
