ScaleGen -- a raster image scale generator. ScaleGen helps you to create scale for your microscope/map/science images. It is usefull when your original image has no scale and you know exact size of the depicted item or when a scale on original image is not sufficient for your purposes. For example when you want to use more images with distinct style of scales in one article -- unified scales look always better.
By mouse you can measure parts of an drag&dropped image eg. from microscope and ScaleGen create automaticly raster image with scale of exactly same size for. When you get your scale from ScaleGen you have to put it to final image yourself.
