is this possible at all?

[pka4916]

If I load a PNG file,  I want to put only a part into a new PNG file, and then save it.
if the image =  300x200,  I want from that image only  300,100   (the top half of that image) 
then then save the new file.

I'm playing for days with this and cant figure it out.
so, is it possible, and if so, how does it work?

thank you so much

How do you copy a part of the image?

Is this board alive?
