Riffing on Raymond Chen's post today about SubtractRect I threw together a toy app which demonstrates three rectangle functions: UnionRect, IntersectRect, and SubtractRect.
Usage:
>rects.exe
rects.exe
union (left1 top1 right1 bottom1) (left2 top2 right2 bottom2) |
intersect (left1 top1 right1 bottom1) (left2 top2 right2 bottom2) |
subtract (left1 top1 right1 bottom1) (left2 top2 right2 bottom2)
rects.exe
union (left1 top1 right1 bottom1) (left2 top2 right2 bottom2) |
intersect (left1 top1 right1 bottom1) (left2 top2 right2 bottom2) |
subtract (left1 top1 right1 bottom1) (left2 top2 right2 bottom2)
Sample output:
>rects.exe union (2 2 6 6) (4 4 8 8)
(left = 2; top = 2; right = 6; bottom = 6)
union (left = 4; top = 4; right = 8; bottom = 8)
= (left = 2; top = 2; right = 8; bottom = 8)
(left = 2; top = 2; right = 6; bottom = 6)
union (left = 4; top = 4; right = 8; bottom = 8)
= (left = 2; top = 2; right = 8; bottom = 8)
Source and binaries (amd64 and x86) attached.
Still no pictures though.
