Subject: Passing function to mapcar
Date: Sun, 01 Sep 2024 23:44:03 +0000 [thread overview]
Message-ID: <7gCipGlilClt_mxSbraoYACoR6rHzQFm-JCI_l8iT9Ql-dSYy5VArUWM5fl2gcKpLfKOnxWiC5VYS0ey7dQTvESkr1c8awVioFwSrJmEM-g=@protonmail.com> (raw)
I am using mapcar to apply the lambda function taking values
in rgb-list as argument c.
(mapcar (lambda (c)
(min 255 (max 0 (round (* c factor)))))
rgb-list)
I think that the function used for mapcar should have only a
single argument. Is this correct ?
What can one do if I want to call a function with more than
a single argument ?
(defun myfunc (c factor)
(min 255 (max 0 (round (* c factor)))))
(mapcar myfunc(c factor) rgb-list)
