yes! completely agree...

I found it interesting I was trying to run this stuff through photoshop, but photoshop turned out to be a weird bottleneck since it's a single process. What happens if 2 images go through automator at the same time? it's a conflict! It's one of the things that led me to look at quartz. Really glad you have the same opinion.

of course the only issue I'm hitting now is the "non-obvious" lack of an explicit alpha composite in the node Library, but I'm looking! I found this class but not sure where it is in Library yet. (is this something I need to add as an additional install?) http://www.quartzcomposer.com/patches/780-ci-stencil-alpha-blend-mode

(or is there another composite function I'm missing with the alpha?)

Ive done several interesting automation test projects several months ago and I would say it’s totally possible and would be straightforward to accomplish. I would also say that in a production environment (opinion following) Graphic Converter combined with OS X file system for auto bulk processing images is solid match within a workflow, capable of applying image adjustments in a procedural way rather than GUI, and then outputting to any folder being “watched” by quartz composer, which is integrated within your patch.

It's been awhile since I've done this, but maybe this general overview will help.

Automator workflows will tend to work with what are called QuartzComposer "protocol" compositions; Graphic Animation, Image Filter, etc.

You will probably want to make an Image Filter protocol composition. Use the QuartzComposer editor template chooser. Edit the composition to your liking.

The simplest thing is probably to place a Composite patch on the editor. Place your original image in one input, the watermark in the other, then find the suitable blend mode for the Composite patch. Take the output of that composite and attach it to the input of the protocol splitter image output.

There may be some more efficient ways, but I'm describing what I think is probably easiest.

In Automator, there are workflows that allow you to then run images through any Image Filter qtz's you place in your Compositions folder. You pretty much choose that, tweak whatever fields are needed, and you should be good to go....if it all still works!

I would guess you could do something like this. Certainly Quartz Composer can do the image processing.

Newbie question trying to determine if Quartz Composer is the tool I need.

I looked in Automator and saw there's a way to use Quartz Composer Compositions in automator to edit images.

I have a background in programming, and node based architecture (from the 3d application Maya). Can I create my own quartz composition to show up in Automator? Supposedly it will add any composition in /Library/Compositions.

And are there any tutorials for doing this? (I'd also be willing to spend a few bucks if there was someone around with the time to answer a few questions).


I want to be able to have automator automatically apply a set image (basically a watermark) over another image using the watermark's alpha channel. And I want it to do this for any image that's placed in that folder. I tried already with a photoshop droplet, but it seems unreliable.


thanks!
