Folks,
Thanks for the comments. What I'm doing is dragging an image that is larger
than the viewing area. I set the loc of the image (according to the mouseloc)
inside a repeat loop. The general idea is below.
On drag
repeat while the mouseStillDown
--set the loc of the image according to the mouseloc
end repeat
end drag
The motion of the image is pretty jerky. It's a pretty large image. The reason
I wanted to add and subtract points is to calculate the new loc for the image.
I do this now by separating out x and y and operating on them individually. I
suspect that most of the time is spent moving that large image, though, instead
of doing the calculations.
The image is a map, and I intend on plotting symbols on it. To speed this up,
I'm plotting on a snapshot of the visible part of the image (which sits on top
of the visible part). The plot will need to be updated each time the map is
dragged or is magnification changed.
If there is a faster way to move a large image around, I'd like to hear of it.
Thanks again,
Bill
