Re: Quartzcomposer-dev Digest, Vol 39, Issue 9

There is a private patch called Color Channels that is capable of doing what you want to do. It controls which RGBA color channels the subpatches can write to. By placing it inside a Render In Image patch you can split the image into RGBA and modify it as you'd like. Keep in mind this patch is not included in QC 3 because it is not yet released. Everything I have read says there is nothing illegal or immoral about using these patches as they are included in OS X but are not made easy to get to. That said, it might not be the best for a production compostion.

To find the private patches try Googling for Quartz Composer private patches.

A simple problem, I know the answer is right in front of me but can't
seem to find it...

How would I go about splitting a single image feed into RGBA or HSBA
component channels, so that I can process each channel individually as
images, and then reassemble (or not) later on in the chain? I'm using
QC3 on leopard.


Thanks!
