"Hi" to all Khoros-Users,
 
i think i have found a "bug" in vrotate:

when i try to rotate a 512x512 (short-)image in a 90 degree angle,
(-d 90) the image losts it's border information.

the first and last row and collom is replaced by "random" zero pixels.

o.k. i know that rotating an image is a big problem because of the
diskret data. but this replacement is hard to find (looks like a normal
X-window border) and the algorithm i use after the rotation gets mad
because of the "high-dynamic" of the data.

just a simple question:

is there no other tool, that can do this 90-degree-angle-rotation for me?
           ~~~~~~~~~~~~
ANY help is wellcome ...
