New Hit Testing Flags
The following new hit testing flags are included in QuickTime 3. These flags are for use with
SpriteMediaHitTestAllSprites
and
SpriteMediaHitTestOneSprite
:
-
spriteHitTestInvisibleSprites
, which you set if you want invisible sprites to be hit tested along with visible ones.
-
spriteHitTestLocInDisplayCoordinates
, which you set if the hit testing point is in display coordinates instead of local sprite track coordinates.
-
spriteHitTestIsClick
, which you set if you want the hit testing operation to pass a click on to the codec currently rendering the sprites image. For example, this can be used to make the Ripple codec ripple.
