; - ) laf... Thank you!

I once tried to divide the image into several sub-areas and get the
projected image of each area, then I merge all the projected images to
get a global projected image, which is very large.
Unfortunately, this method is unreasonable because each projected
image has its unique EYE_POSITION. When IDLgrView is creating the
projected view of the surface, the eye is always positioned directly in
front of the center of the viewplane rectangle. Thus the eye position
of each sub-area is in front of the its own area center, and the global
projected image does not have an universal eye position.

...I really want to punt.
