I have some condition which create rect like that {{x, y}. {width, height}}
{{10, 10},{10, 0}} & {{20, 20}, {10, 10}}
I want to "merge" this 2 rect, that is I want the smallest enclosing rect,
that is: {{10, 10}, {20, 20}}
I was using NSUnionRect
unfortunately due to the way NSUnionRect is implemented I get {{20, 20},
{10, 10}}
looking at the orinigal code, it's because NSUnionRect dismiss any rectangle
which as either a 0 height or width.
I "fixed" what I think is a critical bug with this new version of
NSUnionRect which DON'T dismiss any rect in any case:
line 352, new version:
GS_GEOM_SCOPE NSRect
NSUnionRect(NSRect aRect, NSRect bRect)
{
float minX = MIN(NSMinX(aRect), NSMinX(bRect));
float maxX = MAX(NSMaxX(aRect), NSMaxX(bRect));
float minY = MIN(NSMinY(aRect), NSMinY(bRect));
float maxY = MAX(NSMaxY(aRect), NSMaxY(bRect));
return NSMakeRect(minX, minY, maxX - minX, maxY - minY);
}
what do you think?
(except for the fact it might break some code...)
