Copy bitmap to clipboard

HilaireFernandes
Hi,

A Dr. Geo user asked me about copying a DrGeo canvas view in the system
clipboard, to past it in other tools as a text writer or any other
editing tool.

I looked in Pharo3 and Pharo6, I found text clipboard operation but it
is not clear if there is support for other format?

What about
primAddClipboardData:data:dataFormat:

I would like to copy and paste the DrGeo canvas as PNG content.

I don't know about other platforms, but on linux the clipboard is implemented in this 8kloc C file https://github.com/pharo-project/pharo-vm/blob/e0ce2d9d78c3c7b37bbc12cd8730c6a15f1f057c/opensmalltalk-vm/platforms/unix/vm-display-X11/sqUnixX11.c


From the comments around the code I gather that the author(s) were aware that images can be copied around in clipboard. Whether it actually works I do no know.

(it would be if the clipboard-related code wrote itself into a nice separate file/plugin :))

may be you should turn the copied canvas into a png because it is not
clear how external tools will be able to
do something with an internal representation of the screen.
