Marking distance with path automately

  • May 20, 2016

The blue line is a path with some anchors, then I stroke it with blue brush.

What I want is marking distance lables automately like the red lables with script.

When i supply 3 parameters, the min value ,the max value and lable numbers, and select some anchor, I run the script so that the lables can be painted in a new layer.

Thanks all.

Correct answer c.pfaffenbichler

1. Distances between anchors drawn by Pen Tool can be calculated after i choose two anchors?

I already stated that selected PathPoints can not be assessed directly via Script.

I recommend you abandon that approach, but if you insist you can employ a work-around (copy, create new Path, paste in AM code) and evaluate that newly created Path.

I choose pathpoints by mouse not via script.

                      pic1.select all points 

            pic2.select 3points of line by Direct Selection Tool

How to calculate the choosen part of line in canvas via script?

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

2. How to make lables along the line? Maybe Text Tool ?

One can create Type Layers via AM or DOM code.

Could you give me a demo script ( AM or DOM code ) please? I have never heard it before. Also, you could send it to my email: 279157364@qq.com


I already pointed out a work-around for evaluating the selected PathPoints:

Use ScriptingListener.plugin to record copy, create new path, paste.

The resulting Path contains only the originally selected PathPoints.

As for determining the points and type layers:

// only for open paths without curves!

// only for cornerpoints!

// add numbers along an open path that consists of straight segments;

// 2016, use it at your own risk;

For determining distances on a curved Path the only practical solution I have found is a brute force approach – calculating a high number of additional point on the curve and adding up the distances of those.

If you ever want to look into that you could check out:

Thanks c.p for your script.

I modify the script for labels that are vertical to line.

But some lables are strange, they are inverse to our sight. Maybe I can make it better in some day.

Selected PathPoints cannot be directly evaluated via Script, selected Paths can be – why would you need to select one anchor?

Are all the PathPoints CornerPoints without left and right bezier handles (or bezier handles of length 0)?

When i supply 3 parameters, the min value ,the max value and lable numbers

How do the values relate to the numbers?

What should the numbers indicate exactly (the length of the path, the length over the x-axis, …)?

Please explain the process in more detail.

1. Selecting the pathpoints: Firstly choosing some pathpoints with Path selection tools( shortcut key: a), not with script. Then I want to run the script to create number lables.

2. Direction of line: Anchors are created from right to left. The whole line is a stright line from the whole sight.  Order of lables are the same with anchors' order-- from right to left( small number is always at the right of line, and big number is at the left one).

3. 3 parameters. The 3 parameters can be understood as the scale of line. When I give 3 parameters, the scale is certain. For example [0 10000 10 ], the step is (p2-p1)/p3=1000, the labels are [0 1000 2000 ... 10000]. In my future work, the p3 may be step, so ,the third one can be replaced by step. 3 paras can be [0 10000 1000 ] with 10+1=11 lables or [0 100 20] with 5+1=6 lables.

4.Number indication: the number of lables indicates exactly the length of the path, not x-axis.

I still don’t get it.

Please post screenshots illustrating the steps of the intended process (and what the path/s are like originally, what is getting selected and how that determines the final result).
