An Interactive Introduction to OpenGL Programming

Rendering Bitmaps and
Images
• OpenGL can render blocks of pixels
– Doesn’t understand image formats
• Raster position controls placement of
entire image
– If the raster position is clipped, the entire
block of pixels is not rendered
glDrawPixels( width, height, format,
type, pixels );
glBitmap( width, height, xorig, yorig,
xmove, ymove, bitmap );
