I have hundreds of .bmp guitar tablature files that I would like to add characters to, as well as improve the resolution of. I used paint.net to add the characters to the top of the file, and then I used the Effects -> Sharpen -> 10 command to improve the quality. It now looks a little better than it did when just using MS Paint to add the characters.
Is there anything else I can try to improve the quality of the image, without increasing the screen size? Things I was thinking of are: increasing the pixels/inch (currently 96); saving as a different file type; using a different sharpen number; increasing the screen size of the file before manipulating the image, then reducing it; etc.
The disk size of the file is irrelevant since it's being attached to a video file. tia.
