Cutting / splitting images (png)

Hi, I just had the issue of swimlane images being exported to png files a much to small to read if imported as a png file in MS-Word (contract / agreement). Even with 250% magnification you can’t read it. Solution: put it in devonthink and open it with the devonthink (!) tool for viewing files, mark what you need to copy, copy it and paste it to the MS-Word file. Thank you devonthink team! You just saved me a lot of time.
