[Boost-users] gil and OpenGL

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.
