Thank you all for your responses. My project is under RH linux, using
C++. This is really the first part of my term project, so I just need a
quick and dirty piece of codes to handle this.
To the people who have suggested jpeblib, what keywords or procedures I
should look for in the jpeg manual? I skimmed through the manual the
couldn't find a specific section that details on how to convert an image
to a RGB-array. Thanks again.
I've just tried to "convert" a .jpg file to a .rgb file, as you suggested.
(actually I redirected it to a new file).
> convert picture.jpg -interlace plane rgb:-
the output is a binary file so I can't still read it into an arry in which
each pixel is a RGB vector. Could you elaborate on this? Thanks for your
