Actions/Scripts: Move layer to absolute position instead of translate

[AustinDeh]

Hey all,

Im trying to write a script which takes a layer and moves it to a x/y coordinate on the canvas rather than translates the object a certain amount of pixels. Ive created an action so far and converted it to a script file to try and tweak it but am having trouble understanding the API. I was hoping someone here might be able to help.

Here is the step that I need to adjust from a translate to an absolute position:

  // Transform

  function step9(enabled, withDialog) {

   if (enabled != undefined && !enabled)

   return;

   var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);

   var desc1 = new ActionDescriptor();

   var ref1 = new ActionReference();

   ref1.putEnumerated(cTID('Lyr '), cTID('Ordn'), cTID('Trgt'));

   desc1.putReference(cTID('null'), ref1);

   desc1.putEnumerated(cTID('FTcs'), cTID('QCSt'), sTID("QCSAverage"));

   var desc2 = new ActionDescriptor();

   desc2.putUnitDouble(cTID('Hrzn'), cTID('#Pxl'), 0);

   desc2.putUnitDouble(cTID('Vrtc'), cTID('#Pxl'), 1800);

   desc1.putObject(cTID('Ofst'), cTID('Ofst'), desc2);

   var desc3 = new ActionDescriptor();

   desc3.putEnumerated(sTID("warpStyle"), sTID("warpStyle"), sTID("warpNone"));

   desc3.putDouble(sTID("warpValue"), 0);

   desc3.putDouble(sTID("warpPerspective"), 0);

   desc3.putDouble(sTID("warpPerspectiveOther"), 0);

   desc3.putEnumerated(sTID("warpRotate"), cTID('Ornt'), cTID('Hrzn'));

   desc3.putInteger(sTID("uOrder"), 4);

   desc3.putInteger(sTID("vOrder"), 4);

   desc1.putObject(cTID('warp'), cTID('warp'), desc3);

   desc1.putEnumerated(cTID('Intr'), cTID('Intp'), cTID('Bcbc'));

   executeAction(cTID('Trnf'), desc1, dialogMode);

  };

Thank you in advance for the help!

Moves the top-center point of the layer to the specified position in centimeters or pixels.

This moves left top selected layer(s) to certain pixel position.

Sorry for Humanizer dependency. Maybe somebody could rewrite this into pure AM code.

Anyway this is transform action. But "move" action from r-bin might be 2x faster. But you need to calculate with document DPI if differs from 72DPI.

#include Humanizer.jsx
//https://github.com/jardicc/ActionManagerHumanizer
var desc = 
        {
            "null": {
                    "_enum": "ordinal",
                    "_ref": "layer",
                    "_value": "targetEnum"
                },
            "snapToDocBounds": true,
            "relative": false,
            "position": {
                "_obj": "position",
                "_value": {
                    "horizontal": {
                            "_unit": "pixelsUnit",
                            "_value": 100
                        },
                    "vertical": {
                            "_unit": "pixelsUnit",
                            "_value": 100
                        }
                }
            }
        }
var descMod = Humanizer.objectToDescriptor(desc)[1];
executeAction( stringIDToTypeID( "transform" ), descMod, DialogModes.NO );

Functions work regardless of the reasolution of the file

[Jarda Bereza]

I think I understand. You are specifying units and you are using a bit different action descriptor.

I confused this:

var desc = {
            "null": {
                    "_enum": "ordinal",
                    "_ref": "layer",
                    "_value": "targetEnum"
            },
            "to": {
                "_obj": "point", // probably DPI dependency
                "horizontal": 40,
                "vertical": 50
            },
            "suppressPlayLevelIncrease": true
        }
var descMod = Humanizer.objectToDescriptor(desc)[1];
var data = executeAction( stringIDToTypeID( "move" ), descMod, DialogModes.NO );   

With yours:

var desc = {
    "null": {
        "_enum": "ordinal",
        "_ref": "layer",
        "_value": "targetEnum"
    },
    "to": {
        "_obj": "offset",
        "horizontal": {
            "_unit": "distanceUnit",
            "_value": 40
        },
        "vertical": {
            "_unit": "distanceUnit", //might be in pixel units
            "_value": 50
        }
    }
}
var descMod = Humanizer.objectToDescriptor(desc)[1];
var data = executeAction( stringIDToTypeID( "move" ), descMod, DialogModes.NO );
