[Scilab-users] ?= ?==?utf-8?q? Put an image as the background of an axi

[Philipp Mühlmann]

Just a side question to Antoine:

What do you mean with uicontrol "image".

Do you speak about creating an uicontrol of type "image" and try to put an
image into that uicontrol?

I tried this a couple of times, but didn't manage how to do that.
Never worked.

But I always thought this is a bug from the uicontrol and not from IPD or
SIVP.

Best regards,
Philipp
