Hi all,

Has anyone got a "ready-made" PPM image reading program in C? I have to meet a deadline for a project, so it would really be useful if anyone could provide me with such a program.

Thanks

Can't you just use display(1) from imagemagick?

It is not clear what you want/need. What is wrong with "open" (as in the standard C library function to open a file and read it?

Probably you want the image to be read into a different format. So unless the format is specified the question is not meaningful.

I am using "open", but just that I am getting terribly messed up with the character encodings, Image header, etc.

Basically what I want is access to the individual pixels of the image for a image filtering operation

Hope that information will enable you to help me!

Thanks

Sorry to be so obtuse to begin with. Anyway, you are probably look for the netpbm library which does all these things and more.

Yeah. I was trying to first flirt with the libraries, but as I told earlier I am fighting hard to meet a deadline for a publication. So i thought I will just use the C library for working with Images.

Anyways thanks for the info!
