creating gifs 1649 1
Started by Deleted User
I used to be able to create color .gif files (with RGB values) with old versions of IDL. Now I am using the "WRITE_GIF"function with version IDL 8.3, and I can only create gif's using color tables (not RGB frames), thus greatly limiting color options for my gifs. Do you have any advice
Thanks

I am trying to create a video's from image frames. I have used the "WRITE_VIDEO" function to create .avi, .mp4. and .mpg,but non of these will play in powerpoint. Do you have any solutions for creating useable videos
I used to work with IDL 6.3 and created videos for powerpoint with no trouble. Now I am working with version 8.2. It looks like if I upgrade to 8.4 there is a "IDLffVideoWrite" function. Would that work better than the "WRITE_VIDEO" function, or is it ...

Plot / Ellipse 1721 1
Started by Deleted User
Good morning,
I have created a figure with the command "plot". When the figure is expanded, it changes the size. Also, I have incluided some ellipses (circles), and they are expanded:
If I incluided the aspect_ratio = 1 ---> Circles are ovals.
If I don't incluided the aspect_ratio = 1 ---> When I do the figure bigger, it changes the shape.
So, how could I fix the figure (Window)
I am using: position, location, etc., etc.
I don't know if the problem is in 'plot' or 'ellips...

Floating licence : restrict a maximum of one licence for a range machines 1566 1
Started by Deleted User
Dear all,
We have a floating licence server in my research institute.
My research group (10 people in the institute) have a cluster of machines. We would like to use the IDL floating licences for the cluster.
But we would like to limit the use of this cluster to ONE single licence at a given time.
Therefore here is my question :
Is it possible to configure the licence server to limit to at most one single licence for a range of machines (defined in a group for example).
Then if the cluster i...

Scrolling enabled in widget_base() - what info is available? 1680 0
Started by Deleted User
Hello,
I have a widget_base() that contains several widget_windows() containing image chips. I need to refresh the image chips after a scroll action. It seems that there is no scroll 'event' (i.e. an event structure that gets passed to the event handler). This is too bad because that would be helpful.
The second best bit of information would be if there is some place where I can tell if the scroll has moved - i.e. a change in offset or position. I looked in geometry structure ( widget_info...

3d plot polygon mesh of 3 independent variables 1784 3
Started by Deleted User
Hi,
I have 3 independent variables. I plotted 3d polygon in MATLAB using 'convhull' and then 'trimesh' precedures. But I have to do in IDL. I already plotted a 3d scatter plot using 'plot_3dbox' and then I go for 'qhull' for the delaunay triangulation. However, I am not able to plot the (bound) polygon mesh in my 3d plot. Or, is this triangulation not good for my needs
If anyone can suggest me how to plot the polygon, that will be your kindness.
Thanks,
