how to generate grayscale image

[hakiim35]

Hello, i have a grayscale image(char pointer of pixel intensities). I want to create a grayscale Image with these values. However, PixelPacket only accepts rgb values. How can i generate a grayscale image using Magick++ ?

Thank you.

Set your red, green, and blue components to the same grayscale intensity.
