Bitmap files definition
Bitmap files means images made of pixels such as the formats BMP, TIFF, GIF, PNG, JPEG). Sometimes you may want to convert an image that was not scanned from printed music. It may have been generated by another program, or found on the Internet, or scanned as a grey scale or colour image and then converted by some image processing program. These images often look OK to a person but convert badly or not at all with SharpEye.
