HI..

Is there a efficent way to rotate a X-PIXMAP around a specific
point at a arbitrary fixed point and rotation angle.... 

I am trying to write a interactive X-windows app that allows
rotation of color ppm images... I converting the ppm files
to gif files and using a hacked version of xgif to read the
image... 

If there is a better way to do this(that also works with
rotation) I would gladly except it....


Thanks
