I have used Graphic Converter for years
I have used their program GraphicConverter for years now, and, without a doubt, it is my jack of all trades program for my graphics and photography purposes. I restore old scanned music to like new condition. With this program, I can delete, erase, redraw lines, straighten crooked images, add/reduce dpi, copy & paste....everything I need for it to do before reading it for printing. I use this program every day. They have great support....a forum for users to ask questions about problems, as well as direct contact with the developer if you discover a bug or serious problem with the program. The best thing is that it is a Mac native, program, not a program created for PCs and reworked to work on a Mac, so everything works like other Mac programs.
