Color corrections

This functionality is available only in the Raster module.

A real map or color scheme, as a rule, is performed using a small number of colors, however, when scanning a paper original, a color raster image is obtained, the points of which have several tens or even hundreds of colors. Color filtering and color correction tools are used to prepare images for subsequent complex operations such as binarization, slicing, raster editing, and vectorization. Color filters are also used to improve the quality of images after applying operations that move objects in the image or change the resolution (scaling, alignment, rotation, calibration, or four-point correction).
