Hi, I have just started trying to teach myself javascript. Based on preliminary research, it's become apparent that there are many functions in Photoshop that are either extremely cumbersome or impossible to code by hand without using the Script Listener.
My goal is as follows: first, I will manually load two photos as layers in a single document. Then I will manually place two or more color sampler points on the document. At this point I would like the script to create a curves adjustment layer (ideally clipped to layer 2) and place as individual channel anchor points the RGB data from the color sampler points on Layer 2, and then adjust the output of the points on each channel to the color sampler RGB values of layer 1.
As my first script, I realize this is probably going to be a lot of work.
I did find some code that returns the average value of manually placed color sampler points. Conceptually then, I would need to add code which creates a new curves adjustment layer and adds those RGB values (from a specific layer) as anchor points on the individual channels, and then hides one layer and looks at the RGB values of the color sampler points, and uses them as the output values for each anchor point.
Sounds simple enough from a conceptual standpoint.
I'm looking for some guidance on how to get started.
Which parts will I definitely need Scriptlistener for and will that be adequate to do the job?
How would you recommend I get started on this?
Thanks very much for any input.
