Clipboard processing

[SAMSAM]

Please, tell me an example of a command for processing data inside the clipboard.
For example: a fragment of an image is copied to the clipboard (-clipboard), then converted to gray tones (-grey 256) and replaces the data in the clipboard.
Is it possible?

[xnview]

-o clipboard

[SAMSAM]

-o clipboard

Unfortunately, paired with the "-clipboard" command, it doesn't work...

[xnview]

Code: Select all

nconvert -clipboard -grey 256 -out clipboard

works

I finally understood why this team didn't work for me. The algorithm for working with the clipboard in different graphic editors differs. I consider this topic exhausted and closed.
