Hi Marc,<br>
In Kepler, the "Convert URL to Image" actor is
ptolemy.actor.lib.image.URLToImage:<br>
"The ConvertURLToImage actor reads the URL or path of an image and
outputs the image in a form that can be used by other actors (an
image token)." <br>
<br>
Ptolemy includes interfaces to Java Advanced Imaging (JAI) and Java
Media Framework (JMF).<br>
There was some work done with OpenCV, but it likely only present in
the Ptolemy tree.<br>
<br>
As an aside, the Plotter has a facility where the user can draw a
dataset. In theory, that facility could be <br>
used in an actor to allow the user to draw the dataset and then
output the data.<br>
<br>
Ptolemy can also use the locations of actors in the window as
input. We use this with the wireless model of<br>
computation to indicate how far apart wireless nodes are.<br>
<br>
What sort of graphical input did you have in mind?<br>

I am curious if any graphical input actors that have been
developed. I would like to have a graphical actor that I could
customize for a variety of input from a workflow user.<br>
<br>
Kind regards, Marc<br>
