About CMYK and PGM
CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model commonly used in printing. PGM (Portable Graymap) is a simple image format that stores grayscale pixel data. Converting from CMYK to PGM is often necessary when preparing images for specific applications that require grayscale input, such as image analysis or certain types of image processing. This conversion effectively separates the color information in CMYK and represents it as shades of gray.
