OS_SpriteOp Scale Factors Several OS_SpriteOp calls allow the caller to specify a set of scaling factors by using the following 4-word structure: |_<^{width:4em}. Word | Content | |<^. 0 |<^. X magnification factor| |<^. 1 |<^. Y magnification factor| |<^. 2 |<^. X minification factor| |<^. 3 |<^. Y minification factor| All scale factors must be positive, non-zero integers. For example, the set of scale factors (2,2,3,3) would scale a sprite to two thirds of its original size. h4. See also * [[OS_SpriteOp]] * [[OS_SpriteOp 50]] * [[OS_SpriteOp 52]] * [[OS_SpriteOp 65]]
