Hi Bill
Yes, you are largely right in that most of the routines do as you say,
however it does include the following.
from the GD.pm interface (http://stein.cshl.org/WWW/software/GD/GD.html)
CopyResized
GD::Image::copyResized(sourceImage,dstX,dstY,srcX,srcY,destW,destH,
srcW, srcH) object method
This method is similar to copy() but allows you to choose
different sizes for the source and destination rectangles.
The source and destination rectangle's are specified independently
by (srcW,srcH) and (destW,destH) respectively. copyResized()
will stretch or shrink the image to accomodate the size requirements.
and from the FLY interface (http://www.unimelb.edu.au/fly/)
copyresized x1,y1,x2,y2,dx1,dy1,dx2,dy2,[source-filename.gif|`command`]
Copies region x1,y1 - x2,y2 of source-filename.gif or the
GIF output of command to the area dx1,dy1 - dx2,dy2 of the
image being created/modified, resizing the image to fit.
If x1,y1,x2,y2 are all -1, copy the entire image.
I now remember why I was using it... it was to automatically provide
thumbnails for a postcard site :)
