Virtual Pixel Method

These scripts work at Arbor IM. Do not work at Zbox. Not sure of other servers. These scripts continue from page 1, changing the background of the arcs using the virtual-pixel options.
We saw how this image: exec ("/usr/bin/convert sample/GradMontRz.gif -virtual-pixel black -distort arc 180 sample/skirtB.gif");	Became:
Here are some other options for virtual-pixel:
exec("/usr/bin/convert sample/GradMontRz.gif -virtual-pixel Tile -distort Arc 180 sample/tileARC.gif");
