Xinteranimate [message #18396]

Hi,
I've some troubles with xinteranimate.
I want to realize a short movie with a sample of images ( displayed with tvscl),
overlapped by a circle.
I used the following commands:
<< tvscl,img(*,*,i)
<<plot_circle
<<a=tvrd()
<<XINTERANIMATE, FRAME = i, IMAGE = a
Everything is OK except the color table behaviour. One
image is correct (red table for example) but the next ist wrong (it looks like
an overexposed photograph). Then the next one is correct and the next one is
wrong etc....
I have the same behaviour with other color tables (rainbow18 for example)
I think the problem comes from the tvrd() function. Is there a solution?
I'm using IDL 5.2 running on Digital UNIX V4.0B.
Thanks in advance,
Christophe Marque

A pixmap is not the Z-buffer (in fact, the Z-buffer is sometimes
used as a way around these limitations).

I don't know about Windows 2000, but I suspect it may work
like Windows NT. Here is part of a communication to me
about this very topic from someone who is exceptionally reliable
about these things:

Under NT, device dependent pixmaps are allocated against the
video driver. The video driver can choose to place them on the
card or in system RAM. This is driver dependent. Now, under NT
(unlike the Mac and Unix) driver graphics resources cannot page
so you are limited to system memory no matter what (virtual
memory cannot be used for these pixmaps).

I suspect you are running into a driver limitation.

Cheers,

David

The ability to create MPEG files is licensed separately,
but is free for the asking. XInteranimate uses the IDLgrMPEG
object to do its thing. :-)

Why don't you ask RSI for a short-term softkey if you
are doing an evaluation of IDL.

Cheers,

David

THanks for your prompt replay. I really thought about using IDLgrMPEG
but I don't have it available because this is a free download. I am
wondering if there is a different way to creat the MPEG file, for
instance, being able to turn ON the button on the xinteranimate
window....! but how? unfortunately, the keywords that are used to call
xinteranimate do not work. Am I missing something?

Best regards,
I.C.

I would have a look at the IDLgrMPEG object.
