InDesign script help - Units from selections and units in input boxes

Hi @SmythWharf , I think this is the same question you asked here:

https://community.adobe.com/t5/indesign-discussions/script-ui-issue-script-allows-change-of-w-amp-h-of-many-selected-things-at-once/m-p/14294902#M554397

The part that is still missing from your code is setting the scripting preferences measurement unit to points at the top of the script and resetting at the end outside of the loop. You have to do that because a measurementEditbox always converts the returned values to points, so this works:

// Wrap the script in app.doScript for a single undoable step
app.doScript(function() {
    // Define the dialog
    var myDialog = app.dialogs.add({name: "Change Object Size"});
    with (myDialog.dialogColumns.add()) {
        with (dialogRows.add()) {
            with (dialogColumns.add()) {
                staticTexts.add({staticLabel: "Width:"});
                staticTexts.add({staticLabel: "Height:"});
            }
            with (dialogColumns.add()) {
                var widthEditbox = measurementEditboxes.add({editUnits:app.activeDocument.viewPreferences.horizontalMeasurementUnits});
                var heightEditbox = measurementEditboxes.add({editUnits:app.activeDocument.viewPreferences.verticalMeasurementUnits});
            }
        }
    }

    // Show the dialog
    if (myDialog.show() == true) {
        
/////////////Set Scripting units to points/////////////
        app.scriptPreferences.measurementUnit = MeasurementUnits.POINTS;
        
        // Get the user input values
        var newHeight = widthEditbox.editValue;
        var newWidth = heightEditbox.editValue;

        // Close the dialog
        myDialog.destroy();

        // Get the selected objects
        var selectedObjects = app.activeDocument.selection;

        // Loop through selected objects and change their size from the center
        for (var i = 0; i < selectedObjects.length; i++) {
            var currentObject = selectedObjects[i];

            // Check if the selected object is a valid page item
            if (currentObject.hasOwnProperty("geometricBounds")) {
                // Get the current geometric bounds
                var currentBounds = currentObject.geometricBounds;

                // Calculate the center of the current bounds
                var centerX = (currentBounds[0] + currentBounds[2]) / 2;
                var centerY = (currentBounds[1] + currentBounds[3]) / 2;

                // Calculate the new bounds
                var newBounds = [
                    centerX - newWidth / 2,
                    centerY - newHeight / 2,
                    centerX + newWidth / 2,
                    centerY + newHeight / 2
                ];

                // Apply the new geometric bounds
                currentObject.geometricBounds = newBounds;
            }
        }
        ////////////Reet Scripting units to defaults//////////////
        app.scriptPreferences.measurementUnit = AutoEnum.AUTO_VALUE;
    } else {
        // Dialog was canceled
        myDialog.destroy();
    }
}, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, "Change Object Size");

> How can I either remove the pt

Check the properties of the dialogColumn object. Maybe it has some useful property other than measurementEditBox.

Just throwing my hat at it - not the best at this but hope it helps a little

I'm guessing this probably won't work out of the box - but hope it helps in some way.

// Get the current document unit
var documentUnit = document.measurementUnits;

// Wrap the script in app.doScript for a single undoable step
app.doScript(function() {
    // Define the dialog with dynamic labels based on the document unit
    var myDialog = app.dialogs.add({name: "Change Object Size"});
    with (myDialog.dialogColumns.add()) {
        with (dialogRows.add()) {
            with (dialogColumns.add()) {
                staticTexts.add({staticLabel: "Width: ({0})".format(documentUnit)});
                staticTexts.add({staticLabel: "Height: ({0})".format(documentUnit)});
            }
            with (dialogColumns.add()) {
                var widthEditbox = measurementEditboxes.add();
                var heightEditbox = measurementEditboxes.add();
            }
        }
    }

    // Show the dialog
    if (myDialog.show() == true) {
        // Get the user input values
        var newHeight = widthEditbox.editValue;
        var newWidth = heightEditbox.editValue;

        // Check if both fields are not empty
        if (newHeight && newWidth) {
            // Close the dialog
            myDialog.destroy();

            // Get the selected objects
            var selectedObjects = app.activeDocument.selection;

            // Loop through selected objects and change their size from the center
            for (var i = 0; i < selectedObjects.length; i++) {
                var currentObject = selectedObjects[i];

                // Check if the selected object is a valid page item
                if (currentObject.hasOwnProperty("geometricBounds")) {
                    // Get the current geometric bounds
                    var currentBounds = currentObject.geometricBounds;

                    // Calculate the center of the current bounds
                    var centerX = (currentBounds[0] + currentBounds[2]) / 2;
                    var centerY = (currentBounds[1] + currentBounds[3]) / 2;

                    // Calculate the new bounds
                    var newBounds = [
                        centerX - newWidth / 2,
                        centerY - newHeight / 2,
                        centerX + newWidth / 2,
                        centerY + newHeight / 2
                    ];

                    // Apply the new geometric bounds
                    currentObject.geometricBounds = newBounds;
                }
            }
        } else {
            // Show an error message if a field is empty
            myDialog.alert("Please enter a value for both the width and height.");
        }
    } else {
        // Dialog was canceled
        myDialog.destroy();
    }
