Dear Kamoru Abiodun LAWAL,
Please, how do I insert or paste a logo on a plot?
I don't know whether Ferret can do it or not.
You can use the "convert" from the Imagemagick suite to superimpose a small image onto a larger one:
I would write a pyferret script like
. . . make a plot . . .
frame/file=image.png
SPAWN sleep 1
SPAWN convert image.png log.gif -gravity northeast -geometry -10-10 -composite output.png
That is, call the "convert" command from within the PyFerret script.
Hope this helps,
Ryo
