Re: Invisible GtkImage

[אנטולי קרס נר <tombackton gmail com>]

Hmmm... did you try not to resize the image at all, and see if it gets
resized automatically by the aspect frame? If the ratio of the image
isn't identical to the aspect frame ratio, I guess it may result in each
one of them resizing the other recursively.

Try without the resize code, and see if it works. If not, maybe use some
layout/alignment properties to make the image adapt, rather than
manually setting the new size. Maybe this will work.

I Hope it helps :-)
