Selection/Canvas/Growth - Local Path?

[Richard Feltner]

What exactly does this selection option do/affect when masking/selecting?

Playing around with it using a stylus creates some great artistic scribble mask effects that can be dragged into other areas of the canvas with the M key.

I'm pretty sure that isn't the intended use for it so a brief explanation would be valuable.

Thanks!

Searched online and still can't find an explanation for what selection/canvas/growth-local path is or does. Anybody?

What you want to do is mouse down in the area you want to select, and then move the mouse around so the path before you release is moving across the different colors associated with that part of the image.  If you hold down the shift key, you can add to that selection.  If you hold down the option key, you can mouse down and move the mouse in areas that are not to be selected, and those recorded colors on the pat will modify the selection in the opposite way..

What happens is that a statistical model of the coloring of what you are trying to select (or not select) is built based on the colors stored in the recorded path.

I thought there was a tutorial video that covered this along with the other selection options.  I did cover all of it with the people doing the videos at one point, so let me check with them today and see if it is posted yet or not.

The comment i got from one of them at the time was something long the lines of, oh wow, now that i understand how this selection option works, i actually like it better than the approach used in another popular program, so the local path option is pretty useful once you understand how it works.

I'll put together a better tutorial here later if the tutorial video on different selection options i'm talking about isn't posted online yet.

Terrific - I'll play with it some more. I noticed that it seemed to select certain color ranges if I paused slightly when moving the mouse. When you say the statistical model of coloring is built on the colors stored in the recorded path do you mean that the path is the real time path you are tracing? So it is kinda like the Magic Selection (color range) tools built in other popular programs? Does the zoom level affect the selection process ie are you able to be more specific/refined? Can you do pixel level selection?

Thanks.

Here is the tutorial video on selection operation mode i was referring to.
