The question is quite simple: How to read a .pgm image file into a 2D double array in C. I do not have a .pgm buffer in memory. I would like to read it from the disk into memory.

Would really appreciate if I could get a code snippet. Thank You.

  • Just to clarify; you want to read a .pgm file from disk into memory? Or do you already have a .pgm buffer in memory you want to manipulate? – rzetterberg May 22 '11 at 01:04
  • No. I do not have a pgm buffer in memory. I would like to read it from disk into memory. – zalenix May 22 '11 at 01:07

You probably won't get someone writing you all the code, but here are some useful links that might point you in the right direction:

If its saved as ASCII you could just read it with the "normal" file reading methods of C. You can of course use the netpbm library (linux only?), which gives you functions to handle a pgm file.
