the attachment is a patch with pix_snap2tex object.
When you open the patch for the first time, you can rotate the image loaded with ROTATE number, and then you can take a "snap" with the big red bang.
This works the first time, but if you change the rotation of the image and try to get another snap, pd-window gives to you an "invalid value" message! Why?
Perhaps I have to "reset" the buffer... I don't know. How can I do?
Pix\_snap2tex invalid value
