Apply Image Filter expressions

[tladb]

Is there a list of functions which can be used in the "Apply Image Filter" equations?

The online manual and video only show simple channel arithmetic.

In the Affinity Photo WorkBook - London Calling 2 -  (p234) - lerp(SA,Sb,0.2) is used for "linear interpretation ... mapping the b channel to a mix of a and b channels "
So I assume there would be other functions.

Hi tladb and Welcome to the Forums,

If you look up Expressions in the help file, you'll see this list of other functions
