animation_image_doc.pro

#11 08-26-2008, 05:40 AM

It works for me (WinXP Pro 64bit, IDLpref > Hardware rendering)

IDL> animation_image_doc
% Compiled module: ANIMATION_IMAGE_DOC.
% Compiled module: FILEPATH.
% Compiled module: PATH_SEP.
% Compiled module: READ_BINARY.
IDL> print,!version
{ x86_64 Win32 Windows Microsoft Windows 7.0 Oct 25 2007 64 64}

I also tried IDL6.2 on Linux and there animation_image_doc behaves
strange. When I run it: empty window. Breakpoint in the OnTimer method
breaks, so the timer is running. When I enlarge the window: the frames
appear.

It's the backing store! I had it set to IDL(2) and the animation
doesn't show up. Setting None(0) or System(1) works.

You are correct! I tried with backing store set to System(1) and it
works! Thanks. I had set backing store to IDL(2) because when
displaying a single image my system (WinXP Home) does not handle
backing-store as requested and so any time another window passes over
the image it is "erased" until re-drawn. So I guess I'll just have to
set RETAIN=2 in those cases.

I find this incredibly hard to believe. Are you sure?

I've never used anything but the default (DEVICE, RETAIN=1)
on any Windows computer I've ever owned (lots of them) and
I've never had a window not do backing store correctly
even once.

Cheers,

David

Well, I know what I saw, but am uncertain enough of my own clumsy
knocking around with the object graphics keywords and such to insist
that I didn't make a mistake somewhere (not to mention being VERY
familiar with my seemingly infinite capacity for screw-ups). In fact
running the very same short piece of test code that I ran yesterday
which produced the effect that I described - now seems to work just
fine. I don't think I changed anything - but clearly SOMETHING
changed. Since I'm the only user on my computer......

Circumstance, probably. Happens all the time. :-)
