With the help of EEPDF PDF to Image Converter Command Line, you can easily convert PDF to grayscale image via command line.
Grayscale image is an image that is composed exclusively of shades of gray. The grayscale intensity is stored as an 8-bit integer, giving 256 possible different shades of gray from black to white. Grayscale images are very common, in part because much of today’s display and image capture hardware can only support 8-bit images. In addition, images of this sort are entirely sufficient for many tasks and so there is no need to use more complicated and harder-to-process color images.
