Thank you very much for the responses. I think I should have been much = more clear in my question about the usage for the puFrame or Subwindow. I = apologize. I am working on creating a Virtual MRI using Opengl and PUI. I = read in a MRI data set that prints about 1,000 or so pixels. My main for = writing the last question was I want to do functions/operations within a = set/stationary sized window. I want to do a couple of things with the = pixels, that right now I am having diffculty doing. 1. Alter the size of the pixels using the glScale(), however when I scale = the pixels go outside the range that I would like on my GUI. I want to = scale the pixels but keep the size of display that they are shown in the = same. Hence the reason why I wanted to use either a subwindow or a = puFrame, but I believe now that doing either of these is still not going = to slove my problem.=20 2. I would like to have a user be able to select a section with in the = image that they would like to display. For example I would receive min_x = and min_y and max_x and max_y points from the user; for the desiganted = area with in the pixels that they want to examine. From these points = selection I would like to be able to show the selected area as the same = size as the previous pixel picture was shown.=20 Basically I would like to setup a 50 by 50 viewing area with in the window = that I would be able to conduct pixel manipulation on and always have the = redrawn pixels with in that frame. I have attached the code that I am = working with for further clarification. Thanks again for all the help,=20 Peter Squire |
