Images with GD

I'm working on getting some image creation scripts done and I have one requirement that I'm not sure how to handle. I have a base image that I can create with no problem. The problem comes in that I want to set some text in the exact center of the image. Is there some sort of formula I can use for finding the x,y point to start from based on a string and which font and angle I use in to create it so that I can get the text correctly centered? -Jim _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.
