I have an .eps file image of an open window with countryside view. I need to open the file and remove the view leaving only the window frame. I was told I coulde do this in Affinity Photo so purchased it yesterday. I can open the file ok but do not know how to remove the countryside view and then I need to save the windowframe only as a.png file. Can anyone help please. I need to solve this little problem as soon as poss. Thank you in advance. WINDOW.eps
