FXRuby dynamic drawing canvas and off-screen image buffer resize

Ruby
1

How can I use the drawing canvas and its off-screen image buffer, say
FXImage, to dynamically resize or have its width and height attributes
changed in reply to user interaction with the main window
(FXMainWindow)?

It seems that whem I put initial values to W and H of the canvas or
FXImage,
they remain with its initial values no matter what I do whem resizing
the
main window.

I have to reset its values for each resize, but how?

If you want the image to be the same size as the canvas that you’re
drawing it into, you need to call resize() on the image whenever the
canvas size changes.

Thanks, Lyle
A class to resize(w, h) on image works fine.
I’m very happy with your help.
