Tested in Ubuntu 19.10, ImageMagick 6.9.10. For each pixel you must find a grayscale color value with. This way you get 256 colors from black (R 0, G 0, B 0) to white (R 255, G 255, B 255). Grayscale means, that all components (R, G and B) of the colors have the same value. # Downsize to 400 height to have a reasonable file size for upload here.Ĭonvert -threshold 50 in.jpg threshold-50.jpg Once you have loaded it, you must go through the pixels of the image and convert them to grayscale. Program create files for use with any C compiler : for AVR, ARM, PIC, 8051 and ohter microcontrollers. We could likely have improved that with a better -threshold value, but the beauty of -monochrome is that it is smarter and often works without us having to guess anything.Ĭoncrete example from: wget -O orig.jpg LCD Assistant is a free tool for converting monochromatic bitmaps to data arrays for easy use with programs for embedded systems with microcontrollers and graphics monochromatic LCD displays like a T6963C, KS0108, SED1335 etc. This option uses some smart dithering and generates very visible output: convert -monochrome in.png out.pngĬompare that to a simpler -threshold 50 transform: convert -threshold 50 in.png out.png
