reading pgm format

[vaneric]

Hi,
is it possible to read .pgm image format using java?.I tried
ImageIO.read("my.pgm") but this failed.I was told that JAI api can
read pgm format.Can anyone tell me how i can obtain a BufferedImage
out of it?

RenderedImage rendimg=JAI.create("fileload","my.pgm");

but then how do i obtain a BufferedImage from this?
thanks in advance,
eric

Eric,

Try

BufferedImage bufferedImage = new
RenderedImageAdapter(rendimg).getAsBufferedImage();

this will obtain BufferedImage.

If you can't do it, see this description of the format.

Portable Grey Map files are reputedly very simple. You could read it
in binary and feed it to Java at bit at a time.
