Hi there, depending on the memory layout of you could just cast the
first channel of your first pixel into a byte pointer. BTW, what do
you mean by color information?

This is my first post in any mailinglist ever so i hope i am doing this right.
I successfully integrated the boost::gil module into my code to load some images and process their content so that I can display it as a texture in OpenGL.
My problem right now is the massive performance issue in retrieving the color information from the loaded image.
I am looping through every row and column and retrieve the red, green, blue and alpha color with the get_color method and push those values to a char array.
So I was wondering what the best approach would be to get the color information from the gil image into OpenGL or at least a char array.
Thanks in advance.
