place a pictures and the left=0,top=0

[greless]

hi everybody:

     i want to place a pictures and the left=0,top=0,there is a script to using "offset",but offset is Bad calculation,

(function placeEvent_08499145507813()
    {
    try {
        var d = new ActionDescriptor();
        d.putPath(stringIDToTypeID("null"), new File("~/Pictures/timg.jpg"));
        d.putEnumerated(stringIDToTypeID("freeTransformCenterState"), stringIDToTypeID("quadCenterState"), stringIDToTypeID("QCSAverage"));
        var d1 = new ActionDescriptor();
        d1.putUnitDouble(stringIDToTypeID("horizontal"), stringIDToTypeID("pixelsUnit"), -50);
        d1.putUnitDouble(stringIDToTypeID("vertical"), stringIDToTypeID("pixelsUnit"), -29.5);
        d.putObject(stringIDToTypeID("offset"), stringIDToTypeID("offset"), d1);
        d.putUnitDouble(stringIDToTypeID("width"), stringIDToTypeID("percentUnit"), 67.5);
        d.putUnitDouble(stringIDToTypeID("height"), stringIDToTypeID("percentUnit"), 83.5271317829457);
        executeAction(stringIDToTypeID("placeEvent"), d, DialogModes.NO);
        }
    catch (e) { if (e.number!=8007) { alert("Line: "+e.line+"\n\n"+e,"Bug!",true); throw(e); } }
    }
)();

The place command works differently in different photoshops. And usually very strange.

Do not use offset.

Use the move command to move the layer to the desired position after placeEvent.

[greless]

i'm sorry,but the "move" what be used.

[r-bin · Accepted solution]

var d = new ActionDescriptor();
var r = new ActionReference();
r.putEnumerated(stringIDToTypeID("layer"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));
d.putReference(stringIDToTypeID("null"), r);
var d1 = new ActionDescriptor();
d1.putUnitDouble(stringIDToTypeID("horizontal"), stringIDToTypeID("pixelsUnit"), x);
d1.putUnitDouble(stringIDToTypeID("vertical"),  stringIDToTypeID("pixelsUnit"), y);
d.putObject(stringIDToTypeID("to"), stringIDToTypeID("offset"), d1);
executeAction(stringIDToTypeID("move"), d, DialogModes.NO);

thanks,r-bin，My heart is for you。

This is the end result

var layer=app.activeDocument.activeLayer;
MoveLayerOrigin(layer.bounds[0],layer.bounds[1]);
 function MoveLayerOrigin(top,left)
 {
    try{
            var d = new ActionDescriptor();
            var r = new ActionReference();
            r.putEnumerated(stringIDToTypeID("layer"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));
            d.putReference(stringIDToTypeID("null"), r);
            var d1 = new ActionDescriptor();
            d1.putUnitDouble(stringIDToTypeID("horizontal"), stringIDToTypeID("pixelsUnit"), -top);
            d1.putUnitDouble(stringIDToTypeID("vertical"),  stringIDToTypeID("pixelsUnit"), -left);
            d.putObject(stringIDToTypeID("to"), stringIDToTypeID("offset"), d1);
            executeAction(stringIDToTypeID("move"), d, DialogModes.NO);
        }
        catch(e){alert(e)}
    }

Don't forget to set app.preferences.rulerUnits to pixels, so that layer.bounds would be in the correct units.

[greless]

sure enough It does have an effect, And that sort of thing, thank you for your notice

app.preferences.rulerUnits = Units.PIXELS

As a scripting beginner, my simple solution would have been to do what I would have done using an action:

#target photoshop
// Select All
  app.activeDocument.selection.selectAll();
// Align - Clean SL
Algn();
function Algn() {
  var c2t = function (s) {
  return app.charIDToTypeID(s);
  };
  var s2t = function (s) {
  return app.stringIDToTypeID(s);
  };
  var descriptor = new ActionDescriptor();
  var descriptor2 = new ActionDescriptor();
  var reference = new ActionReference();
  var reference2 = new ActionReference();
// Align Top
  reference2.putEnumerated( s2t( "layer" ), s2t( "ordinal" ), s2t( "targetEnum" ));
  descriptor2.putReference( c2t( "null" ), reference2 );
  descriptor2.putEnumerated( s2t( "using" ), s2t( "alignDistributeSelector" ), s2t( "ADSTops" ));
  executeAction( c2t( "Algn" ), descriptor2, DialogModes.NO );
// Align Left
  reference.putEnumerated( s2t( "layer" ), s2t( "ordinal" ), s2t( "targetEnum" ));
  descriptor.putReference( c2t( "null" ), reference );
  descriptor.putEnumerated( s2t( "using" ), s2t( "alignDistributeSelector" ), s2t( "ADSLefts" ));
  executeAction( c2t( "Algn" ), descriptor, DialogModes.NO );
}
// Deselect
  app.activeDocument.selection.deselect();

This is also a feasible method,Thank you for your reply.it would be very helpful to me,

hello,

i want to fix the width/height in placement,but replace

1.   d.putUnitDouble(stringIDToTypeID("width"), stringIDToTypeID("percentUnit"), 67.5);  
2.   d.putUnitDouble(stringIDToTypeID("height"), stringIDToTypeID("percentUnit"), 83.5271317829457); 

to

1.   d.putUnitDouble(stringIDToTypeID("width"), stringIDToTypeID("pixelsUnit"), 50);  
2.   d.putUnitDouble(stringIDToTypeID("height"), stringIDToTypeID("pixelsUnit"), 50);

is unfeasible.could you specify the width height when placing?

[r-bin]

This is a long-standing bug (or legalized feature) in Photoshop.
The transform command always perceives width and height as percentages, regardless of the type of units specified.

[greless]

all right,so does it have a formula to convert from pixels to percent?

[r-bin]

Can do so
1. set "Resize image during place" to true;
2. resize canvas to 50x50 px
3. select all
4. place
5. resize canvas to original

Will not work if the original image is less than 50x50 px

P.S.

To know the percentages you need to know the size of the placed image in pixels..
You know that?

[greless]

This is a really bad thing,thank you

[r-bin]

You can transform after place.

pcnt_w = desired_width_px / layer_width_in_px * 100;

pcnt_h = desired_height_px / layer_height_in_px * 100;
