load image

[federico di lodovico <dilodovico jumpy it>]

Hi,
I have a grabber card (meteor 2). I wrote a program in C which gets a 
pgm image (black and white)
from the buffer and writes it on the disk. Now, I want to display the 
image on the screen. I read how to use gtk to
 load an image from a file on the disk (gtk_image_new_from_file(file)). 
However, I don't  want to load the image from
a file but I want to use the image I put in the memory buffer, how can 
I load it?
thanks
federico
