Width/Height return % unit instead px

[willy_sm]

here the code:

        photoshop.open(File(sFolderImg + nCont + "D.jpg"));

        var imgD = app.activeDocument;

        photoshop.open(File(sFolderImg + nCont + "R.jpg"));

        var imgR= app.activeDocument;

        //alert (imgD.name);

        //alert (imgD.Width.as("px"));

        var imgLottoW=imgD.width.as('px') + imgR.width.as('px');

imgD.width returs always a 100% and using .as('px') retun NaN:

I need to get the value in Pixel.

Any idea?

Thanks

Set Photoshop units.  Ypu may want to add some boiler plate code before you get int your processing code. for example:

function main() {
  // declare local variables
  var orig_ruler_units = app.preferences.rulerUnits;
  var orig_type_units = app.preferences.typeUnits;
  var orig_display_dialogs = app.displayDialogs;
  app.preferences.rulerUnits = Units.PIXELS; // Set the ruler units to PIXELS
  app.preferences.typeUnits = TypeUnits.POINTS;   // Set Type units to POINTS
  app.displayDialogs = DialogModes.NO; // Set Dialogs off
  try { code(); }
  // display error message if something goes wrong
  catch(e) { alert(e + ': on line ' + e.line, 'Script Error', true); }
        // catch(e){$.writeln(e)}  
  app.displayDialogs = orig_display_dialogs; // Reset display dialogs 
  app.preferences.typeUnits  = orig_type_units; // Reset ruler units to original settings 
  app.preferences.rulerUnits = orig_ruler_units; // Reset units to original settings
}

You are also using Document canvas as image width  and height Image can be on layers and layers be any size  if thers are areas outside the document canvas the document canvas size is like a clipping mask.  Layer have rectangle bounds.

// enable double-clicking from Mac Finder or Windows Explorer
#target photoshop // this command only works in Photoshop CS2 and higher
// bring application forward for double-click events
app.bringToFront();
// Save the current preferences
var startRulerUnits = app.preferences.rulerUnits;
// Set Photoshop to use pixels 
app.preferences.rulerUnits = Units.PIXELS;
try{
  var LB = activeDocument.activeLayer.bounds;
  var LWidth = (LB[2].value) - (LB[0].value);
  var LHeight = (LB[3].value) - (LB[1].value);
  MarkX((LB[0].value + LWidth/2));
  MarkX(LB[0].value);
  MarkX(LB[2].value);
  MarkY((LB[1].value + LHeight/2));
  MarkY(LB[1].value)
  MarkY(LB[3].value)
  alert("'" + activeDocument.activeLayer.name + "' Layer Bounds\nTop Left " +  LB[0].value + "X," +  LB[1].value + "Y   Bottom Right "  +  LB[2].value + "X," +  LB[3].value
  + "Y\nWidth " +  LWidth + "px   Height " + LHeight +"px" 
  + "\nLayer center relative to canvas " + (LB[0].value + LWidth/2) + "X," +  (LB[1].value + LHeight/2) +"Y" 
  );
}
catch(e){alert("Requires a layer targered");}
// Return the app preferences
app.preferences.rulerUnits = startRulerUnits;
function MarkX(x) {
// =======================================================
var idMk = charIDToTypeID( "Mk  " );
    var desc61 = new ActionDescriptor();
    var idNw = charIDToTypeID( "Nw  " );
        var desc62 = new ActionDescriptor();
        var idPstn = charIDToTypeID( "Pstn" );
        var idPxl = charIDToTypeID( "#Pxl" );
        desc62.putUnitDouble( idPstn, idPxl, x);
        var idOrnt = charIDToTypeID( "Ornt" );
        var idOrnt = charIDToTypeID( "Ornt" );
        var idVrtc = charIDToTypeID( "Vrtc" );
        desc62.putEnumerated( idOrnt, idOrnt, idVrtc );
    var idGd = charIDToTypeID( "Gd  " );
    desc61.putObject( idNw, idGd, desc62 );
executeAction( idMk, desc61, DialogModes.NO );
}
function MarkY(y) {
// =======================================================
var idMk = charIDToTypeID( "Mk  " );
    var desc63 = new ActionDescriptor();
    var idNw = charIDToTypeID( "Nw  " );
        var desc64 = new ActionDescriptor();
        var idPstn = charIDToTypeID( "Pstn" );
        var idPxl = charIDToTypeID( "#Pxl" );
        desc64.putUnitDouble( idPstn, idPxl, y );
        var idOrnt = charIDToTypeID( "Ornt" );
        var idOrnt = charIDToTypeID( "Ornt" );
        var idHrzn = charIDToTypeID( "Hrzn" );
        desc64.putEnumerated( idOrnt, idOrnt, idHrzn );
    var idGd = charIDToTypeID( "Gd  " );
    desc63.putObject( idNw, idGd, desc64 );
executeAction( idMk, desc63, DialogModes.NO );
}

Sorry but i got the similar problem when trying to get width and height of active document. And change Unit to Pixel doesn't work

I just open 1 png image into photoshop then run the script. Alert width and height and got "NaN px"

Here is my simple code:

var startRulerUnits = app.preferences.rulerUnits;

app.preferences.rulerUnits = Units.PIXELS;

try{

    var doc = app.activeDocument;

    var currentWidth = doc.width;

    var currentHeight = doc.height;

    alert(currentWidth);

    alert(currentHeight);

    var lyrBound = doc.activeLayer.bounds;

    var LWidth = (lyrBound[2].value) - (lyrBound[0].value);

    var LHeight = (lyrBound[3].value) - (lyrBound[1].value);

    alert(LWidth);

    alert(LHeight);

}catch(e){

    alert(e);

}

app.preferences.rulerUnits = startRulerUnits;

I tried this script with 2 png image file: "spark_1" and "spark_1_resize"

 - "spark_1": 1024x1024 px => script showing "NaN px" with it

- "spark_1_resize": 512x512 px => script works and showing "512px"

I have no idea why is that

I really appreciate with any help ❤
Thank you

@Vũ Ngọc22029655edlq 

spark_1.png has a resolution of 0 ppi (zero)

spark_1_resize.png has a resolution of 1 ppi (one)

If you use image size with resampling turned off and assign any PPI value, then spark_1.png will no longer error with "not a number".

The question is, how did you create an image with 0 ppi? Photoshop will not let you do that, so it must have come from some other software or had metadata resolution changed to zero.

Thank you. You saved my life
I know there is different between these images but i have no idea what it is

Hi willy.sm,

the preferences.rulerUnits are your friend:

if(documents.length >1) {
var startRulerUnits = preferences.rulerUnits;
preferences.rulerUnits = Units.PIXELS;
//var imgR = documents[0];
//var imgD = documents[1];
//alert (documents[0].width);
alert (documents[0].width.as('px'));
//alert (documents[0].width.as('px'),'px');
//alert (documents[1].width);
alert (documents[1].width.as('px'));
//alert (documents[1].width.as('px'),'px');
preferences.rulerUnits = startRulerUnits; // Reset units to original settings  
}

Have fun
