I setup a simple Win32 Console mode application that uses GLUT. I created an array of bytes that holds pixel data that is plotted on a window at coordinates 0,0 with glDrawPixels. The image appears fine but when I resize the window, the image moves; especially when I resize the window vertically the image moves in the opposite direction and actually it gets drawn over the desktop if it moves outside the window! I used GLSetup and my video card is an ATI 3D Rage Pro. Has anyone encountered such problems? Any suggestions will be appreciated. ------------------------------------------------ DaWizard http://members.home.com/ahmadkabani http://www.geocities.com/ahmadkabani ------------------------------------------------

drawpixels draws at the current rasterization position.
use glRasterPosi(..) to change

I am using glRasterPos2i(). Here''s the code to display the image:

glClear( GL_COLOR_BUFFER_BIT );

glRasterPos2i( 0.0, 0.0 );
glDrawPixels( 64, 64, GL_RGB, GL_UNSIGNED_BYTE, image );

glFlush();

It seems its a problem with the OpenGL drivers. The code works fine on a different machine.
