Use ImageMagick for grayscale image processing in Windows

1. convert a single image to a grayscale image

Convert image.png-colorspace gray image-gray.png. 

2. batch conversion

Mkdir out <br/> for % B in (*. PNG) Do convert "% B"-colorspace gray "Out/% B"

Note: The preceding commands must be run in the DOS environment. You must install ImageMagick before using the convert command. I like to use its portable version. After decompression, I can add the ImageMagick path to the environment variables to make it easy to use.
