Program CopyMaskDemo;{copyright ©,1987...Duane Blehm,HomeTown Software}
|
|
{This program illustrates using the CopyMask() ROM procedure for animation.
|
|
Note: CopyMask and CalcMask are NOT available in the 64k ROMs.
|
|
We just set up everything so we could achieve the same 'effect' as we did
|
|
with CopyBits and regions in the Animation Demo. We're sure there are
|
|
some better examples of how CopyMask might be used... thought out with
|
|
its features in mind. See Inside Mac vol. 4 or Technical Note #57 for
|
|
specs. on these and other 'new' 128k ROM Quickdraw routines.}

we make FlowerMap.baseAddr point to it and invert it so the fly is drawn
|
|
'outside' the flower edges (the 'flower' becomes white instead black). The
|
|
MaskMap needs to be size of the area the fly will be flying over, and we
|
|
have a RoundRect border which includes the flower area. So we fill the
|
|
RoundRect area with black and copyBits the inverted Flower mask from
|
|
FlowerMap. (see Paint document for illustration of this) Now there is
|
|
black everywhere in the MaskMap we want the Fly to be drawn on the screen
|

except the 'coordinates' are not the same. All we need to do is start

the MaskRect over the MaskMap in sync with the flyRect in our window so
