Ok, sorry for the length of this but it's a bit of a convoluted problem.
I'm wanting to draw a long and thin rectangle in an NSImage. Easy
enough. The problem is it was to be rotated a certain number of
degrees. With the data I have to draw it, I can do it three ways. Draw
a stroke from an NSPoint to another NSPoint and set the stroke width to
what I want, create an NSRect of the right dimensions and transform it
to rotate it or create four NSPoints, one for every corner, and create
an NSBezierPath between then all. Not hard either way.
The problem is, I have an other NSRect (just a regular one this time -
no rotation) and I have to determine if the first rectangle (no longer
a simple NSRect) and the second one intersect at all or if the second
one is completely within the first.
The solution to the second problem will determine which method I use to
draw the first rectangle. Has anyone encountered a similar problem of
determining if an NSRect is within the bounds of or intersects a
polygon defined by NSPoints?
Regards,
Stephen Colebrook
