Hello,
I created a dataengine for the German "Shit Happens!" comic situated at
www.ruth.de and got the permission by the author to publish the code.
Though there is one problem left I can't solve and need your help with.
He wrote that over every comic there should be this banner [1] so that
everyone allways knows the comic's name. Similar to the way it looks
like on his main page [2].
Yet I have no clue how to combine two pictures in one QImage -- if that
is even possible -- especially if one is wider than the other.
Can you help me please?
If none knows a way how to do it I'll ask him if I can also do it
without that banner, though I won't do it before trying -- it's not my
comic after all.
Cheers!
