feComponentTransfer -- request for linear=equalize

feComponentTransfer allows the redefinition of the color density function on
any of an image's four channels.

 

One can use the discrete and linear attributes to play with the manual
adjustment of "equalizing" a channel - to make it appear to be uniformly
distributed over 0 to 255.

I find equalization to be handy in auto-tracing contours and the like.

 

It would be nice to have the ability to auto-equalize a channel. 

 

Just a thought.

 

Cheers

David
