I'll do that, thanks for the push in the right direction.

Ah, thank you for that. This will allow me to scrap much of my HTML

The images spat out seem to be quite small, which is a real bonus.
I need to use CGShading, because a lot of people will be running this
on 10.4 (I assume they won't be able to use the other way)?

I'm guessing cornerSize is an int?
so i/cornerSize will always return 0, so asin(i/cornerSize) will
always return 0 so cos(asin(i/cornerSize)) will always return 1 so (1-
cos(asin(i/cornerSize))) will always return 0
you want to do i/(float) cornerSize

Hello,
I am trying to convert the following from Javascript to Cocoa ObjC:
var retVal = Math.round(cornerSize*(1-Math.cos(Math.asin(i/
cornerSize;
return retVal;
Now retVal _must_ be an int, because the value is used as a margin
I think there is more than one problem here. You may want to get a
good book about the C language (Obj-C is just a superset of C).
Variables i, cornerSize are passed to the function from a for loop.
i being the counter for the loop, cornerSize being the size of
corner desired by the user.
Thanks for your incredibly swift replies!
changing float retVal to double retVal, using return
lround(retVal); and casting ints as doubles in the formula gave me
some real values, which is wonderful!

The C function sin() takes radians as its parameter. In order to use
degrees you need to multiply by M_PI and divide

Note that cos(asin(x)) = sqrt(1-x*x).
HTH.
