    How to use Color Key Masking with DeviceGray Image

    joeln3 Community Member

      Hello,

       

      I'm wondering how to use Color Key Masking with DeviceGray image. Actually I have a RGB image which uses Mask values and after a conversion to Gray I lost the "transparancy".

       

      So is it possible to use the Mask value for DeviceGray and if yes how can I do that. I know that the mask will be [a b] instead of [a b c d e f] because I have only one color but I don't know how to create it.

       

      Thanks in advance,

      Joe
