Hi there,
I am having trouble figuring out how I can inspect the rgb values of a gif
image using the normal Java APIs. I am not interested in drawing the image
at all, I just want to know the color of all the pixels in the image.
Here's some pseudo code to illustrate what I mean:
load image from file "image.gif"
for all pixels in image
if color = green
output a message
if color = blue
output a message
next pixel
I have got as far as loading the Image into a BufferedImage, but I dont know
how to get at the pixels, can anybody help me?
Thanks,
J
