In this quick video, I answer a fan's questions about how best to output a map to an image file in such a way as to 'trim' the output. In addition, I use the same method to create a 'zoomed in map' from the larger map image.
Note 1: During this video I reset some settings for JPG output, but then - as Zethnar points out - use a PNG setting that completely ignores them. It's a good idea to set your JPG settings high when you are in the Options window as CC3 remembers them and, if you are like me, you often forget to check them once set. When I saw those settings, I went into autopilot mode and just began adjusting them without really thinking how that would sound. My apologies for any confusion! :-O
