mosaic

Hi everybody,

I would like to apply a picture as a mosaic on a surface.

I intended to use colorpic. I can scale my picture (using -s). But I did
not
found out if there is a possibility to apply my scaled image on a
surface that is
bigger than the picture in order to get a mosaic.

Thank you for any advice.

Kind regards

Stephane

If you use the "picture.cal" function file, then the
"pic_u" and "pic_v" coordinate variables will map the
image once to the location you specify. If you use the
variables "tile_u" and "tile_v" instead, then the
picture will get repeated in both directions.
