Hi,

I have recently started using IDL to come up with an image
analysis program and I have come up with a way of extracting pixel
intensities along an arbitrary line specified by the cursor (a simple
y=mx+c job) but I'm stumped on how to extend this to extract
information along curves (like line profiles along a spline curve for
instance). I've heard of methods using interpolation, but I've found
the help a bit confusing when it comes to how to apply it.

Thanks,

James Harrison
