Examples of com.sun.image.codec.jpeg.JPEGImageDecoder.decodeAsRaster()

com.sun.image.codec.jpeg.JPEGImageDecoder.decodeAsRaster()
Decode the JPEG stream that was passed as part of construction. The JPEG decompression will be performed according to the current settings of the JPEGDecodeParam object. For a tables only stream this will return null. @return Raster containg the image data. Colorspace and otherpertinent information can be obtained from the JPEGDecodeParam object. @exception ImageFormatException if irregularities in the JPEGstream or an unknown condition is encountered.
