Script to count brush strokes

[boydb86060677]

I was wondering if someone could point me to some scripting that counted something on a layer.  I have layers where I put colored dots on an item. Each layer gets it's own dot color.  I haven't been able to find any previous thread showing anything similar.

thanks!

Photoshop does not give scripts access to image pixels.

That is you can calculate the number of points either by indirect methods (they can be selected by color, but I don’t know the way how to divide the selection into separate objects), or save each layer as an image and give it to scripts / programs for processing outside of Photoshop.

I saw Count Tool but never used and never checked how to use it. It's adding number of clicks indeed 🙂

If I understand correctly: each dot is on a separate layer, then you can count how many layers there are. To determine if a dot is on the layer, you could check the layer bounds size, and if it is over the dot size, you could exclude that layer.

I think I found a workaround, and maybe someone can help me.  

I found this: 

var doc=activeDocument;
var firstpath=doc.pathItems[0]; // Assing Path 
firstpath.select(); // Select Path
var pathpointcount = firstpath.subPathItems[0].pathPoints.length;
alert (pathpointcount);

This allows me to count the number of anchor points on a path. If I turn off spacing on the brush tool it will only stroke the anchor points and not the path, which actually gives me what I want. A way to both add dots and then count them.  I'd need a brush script that just allows me to select a color (say red) a pixel size and then turn off spacing.

I'm a bit confused however, as all the code examples I've seen for path stroking, the example draws the path, and I just want to draw the path myself and stroke it using a brush with no spacing. 

Can someone help?

Also, this site is extremely useful!

If you want to draw a path and have a dot drawn on each anchor point, you can try this script. You can change the color by editing the colors at the top of the script, and you can edit the size of the dots also - make sure you're working in pixels units.

Too bad forum developers still didn't give more space for codes 😞

[boydb86060677]

thank you! One last question. Is there any way to keep those shapes all on one layer?

[Chuck Uebele]

Try this. Just make sure you're on your path layer, when you run the script.
