when I go to the image/square size menu
I select centimeters and enter a value of 10cm
when I convert the action instead of 10cm I find the value of 283.000000, I can't understand where I'm wrong
someone help me for this.

Actions and scripting

I thought it was simpler Now I'll see if I can find something more intuitive.

Your recent topics have been about UXP.

Now it seems that you are using legacy ExtendScript?

It all depends on the current resolution, I'm not sure if this helps or not?

var theRes = app.activeDocument.resolution; // PPI
var theUnitAsCM = (theRes/2.54); // 1 CM
alert("The resolution in PPI divided by 2.54:\r" + theUnitAsCM + "\r\rHowever, we can't have a floating value!");
oneCMasPX = parseInt(theUnitAsCM); // 1 CM to PX integer
alert("1 CM in PX at the current Res:\r" + oneCMasPX);

You can set ruler units in your code, however, Photoshop is always using pixels as the native unit.

Stefano I have tried all the methods but none of them work for me, What's the point of putting centimeters if you can't use it?

Pixels are the native unit of measure.

Canvas size and scripts allow for entry in inches, cm, mm etc., however, they are always going to need to be translated into pixels.

Stefano ho scoperto che per realizzare 1 cm servono circa 29px a 72dpi in modo da poter creare una formula, ma non ho proprio idea di come crearla. hai qualche idea?

la formula è questa

cm x dpi: 2,54

1x72:2,54=28,34

How do I get the calculation done for example if I put 1cm in edittext how to do the formula to do the calculation.
