reading an image file into clipboard

[Juge]

I have a commercial software which has a Tcl API. I have a possibility of saving an image from the software into a file - for example in png format.
I would like to use this feature to save the file into the windows clipboard so that I can get easily screenshots of the GUI and transfer them over the clipboard to powerpoint or so.

Now I can use image:
image create photo GUIScreenshotImg -file [file join $tmpDir screenshot.png]

but how can I transfer that to clipboard?

Have you tried the clipboard command?

Yes, well - I am using clipboard for copying text, but I just do not know how a binary data is transfered with the clipboard command so that it is pasted again as a picture in another application, for example Powerpoint.

On the top of that - I would be glad if I could realize this in a platform independent way...

There is something called twapi package but it seems to be only for windows.

Yes, TWAPI is a marvelous package, but it is for Windows only, as it implements interfaces to the Windows system API.

One way out would be to use the clipboard command to do X Window specific things (my guess is that it is geared for that) and use TWAPI for Windows. Hide both in a little OS-independent layer and you're almost there (I do not know how OSX works with such things)
