Re: Storing XYPlotter graph as video

[Kevin Ruland]

Nandita,

Don't know about an actor, but you can take a sequence of static images 
and make them into a movie (animated gif or mpeg) using ImageMagick.

Hi there,
I had a question,  if there are any  actors /ways to store the results 
plotted on an XY Plotter as a video? My workflow continously plots 
data in a loop and can i store the result at some point as video? If 
not can i store graph as an image?

thanks!

Hi there,Thats a good idea. Are there any clues/ links on how to save the plot as an image in ptolemy?Thanks!nandita.Kevin Ruland <[EMAIL PROTECTED]> wrote:  Nandita,Don't know about an actor, but you can take a sequence of static images and make them into a movie (animated gif or mpeg) using ImageMagick.KevinNandita Mangal wrote:> Hi there,> I had a question,  if there are any  actors /ways to store the results > plotted on an XY Plotter as a video?

Thanks for the quick reply! I guess I can create an actor which  repeatedly takes screenshots (given a certain refresh rate) and saves  to files as you suggested :).  images delay about 10-15 secs.

If it's a reasonable number and you have time between refreshes, you could simply do screenshots and then crop them to isolate the plot.

well its an infinitely looping workflow, & I  keep getting values to plot. So I was thinking of makign the user  specify how long  he wanted to video to be (like 2-4 mins) and  depending on that (with refresh rate of specifiied secs) get the images.

Hi Nandita,

Ptplot can export Encapsulated Postscript (EPS) files, see the 
PlotBox.export() method.

We have contributed code for exporting to png, but did not fold it in
because it is probably GPL'd and want to keep Ptplot clean of GPL.
The code can be found at
http://ptolemy.eecs.berkeley.edu/java/ptplot/exportPNG-0.0.1.patch.gz

It might be possible to do this in a non-GPL'd fashion.
Or, you could hack in the changes and see if it works for you.

well its an infinitely looping workflow, & I  keep getting values to plot. 
   So I was thinking of makign the user  specify how long  he wanted to video t
   o be (like 2-4 mins) and  depending on that (with refresh rate of specifiied
secs) get the images.
  Thanks!

  thanks for the link! Also I guess i can use PlotBox.exportImage() to getBufferedImage of plot instead.
