Grayscale

Use Grayscale to render images in shades of black, white, and gray.

For example, if you have the following image:

unprocessed imageunprocessed image

You can use the Grayscale transformation to create a black, white, and gray image:

grayscale appliedgrayscale applied

If you add the IMQuery transformation to a policy, use the im variable, and select Grayscale, you can use a query string to create a black, white and gray version of any image using this policy. See Syntax and Examples for the syntax for the query string parameter.
