Hello,

I am trying to make a tcl/tk GUI front end for a python script which returns a figure. I am trying to display the figure in a frame and try as I might I cannot get this to work. I have tried reading the image/photo stuff and also tried to embed picture viewer into the frame with no avail. I can also (if absolutely need be) have the python script save the image to a temp file so tk can display it (would most likely be a png if we went that route). Please help! This has been an on going issue for me. Thank you!

Well, I have no idea about your specific application. However, it seems, to me, that a good place to start would be to write a basic Tcl/Tk program that reads a static image file and displays it. Once you have that program written, then at the very least you could have your python program write out a static image file and display it from your tcl/tk program.

To move along farther, you have to then make some decision on how to get the image data from the python program to the tcl/tk program in a fashion that could be displayed. A number of techniques for exchanging data between two processes are mentioned at [inventory of ipc methods].

A simple example of what Larry mentioned above would be:
   * Download and install ActiveTcl (or build Tcl, Tk, and Img on your own).
   * Create your image and save it into a file, such as ''''mypngimg.png'''. If your image is a .jpg, .tiff, .gif, or some other format, then you will need to change the [image create] line below.
   * Save the following lines to the file '''show_img.tcl'''.

======
package require Img
set myimage [image create photo -file mypngimg.png]
label .l1 -image $myimage
pack .l1
======

   * Run it from a shell prompt with
======
wish show_img.tcl
======
(or wish8.5.exe, depending on your platform).
