Subject: Re: Scaling image with FXRuby

Make sure IMAGE_KEEP flag is passed when you construct a FXIcon. icon.create 
will throw away the icon data if you don't pass this flag. Scaling is done 
only on the client side. If there's no client side data, it will do a normal 
resize and the content of the image is then undefined. 

Another option is to do a create after scaling the icon.

Hope this helps,

    Sander
