Maximum printing sizes vary depending on the dpi of the print. A 300dpi print has a maximum size of 6.8 inches, a 200dpi print has a maximum size of 10.2 inches and a 150dpi print has a maximum size of 13.6 inches. The image layers in MapCast are not editable for end users to manipulate, but your local display can be usually adjusted for brightness and contrast. Consult your specific software provider for instructions on how to do this.
