I need to take a CGPath (a set of lines, curves, etc.) and scale the

Do I need to use CGPathApply somehow?
Typically you would just scale the context that you are drawing the
path
to...
Without further information as to what you're trying to accomplish, we
can't see
what the real problem is.
Making some assumptions:
1. If you are constructing the path yourself, surely simple
multiplication of the
path coordinates by the scale factor(s) prior to adding the
specific element
to the path should do the trick.
2. If you have been handed a path and need to scale it, you can use
a Path
Applier function in conjunction with CGPathApply to play back
each element
of the path. See CGPathApply, CGPathApplierFunction, and
CGPathElement
for further details.
