Can't change Measurement Unit

[Gregorio Pellegrino]

Hi,

I'm developing a script. I would like to manage dimensions in millimeters; so I added at the top of the script:

app.scriptPreferences.measurementUnit = MeasurementUnits.MILLIMETERS;

But then I try to resize the page, and the dimensions are managed as points:

app.activeWindow.activePage.resize(CoordinateSpaces.INNER_COORDINATES, AnchorPoint.CENTER_ANCHOR, ResizeMethods.REPLACING_CURRENT_DIMENSIONS_WITH, [240, 100]);

Can you help me to understand where I'm wrong?

Hi,

Personally, about MeasurementsUnits:

// ----------- Script beginning -----------
var myDoc = app.activeDocument;
var savedHorizontalMeasurementUnits = myDoc.viewPreferences.horizontalMeasurementUnits;  
var savedVerticalMeasurementUnits = myDoc.viewPreferences.verticalMeasurementUnits;  
myDoc.viewPreferences.horizontalMeasurementUnits = MeasurementUnits.MILLIMETERS;  
myDoc.viewPreferences.verticalMeasurementUnits = MeasurementUnits.MILLIMETERS;
………………
// ----------- Script end -----------
myDoc.viewPreferences.horizontalMeasurementUnits = savedHorizontalMeasurementUnits;  
myDoc.viewPreferences.verticalMeasurementUnits = savedVerticalMeasurementUnits;

It doesn't work in my environment... Can't understand!

Hi Gregorio,

it is not working in any environment.

all x and y values for resize() are accepted as points only.
The same with reframe() and transform().

There is UnitValue you could use to do the necessary conversions.

var convertedValue = UnitValue(100,MeasurementUnits.MILLIMETERS).as(MeasurementUnits.POINTS);

Hi Uwe,

Right! 

// ----------- Script beginning -----------  
var myDoc = app.activeDocument;  
var savedHorizontalMeasurementUnits = myDoc.viewPreferences.horizontalMeasurementUnits;    
var savedVerticalMeasurementUnits = myDoc.viewPreferences.verticalMeasurementUnits;    
myDoc.viewPreferences.horizontalMeasurementUnits = MeasurementUnits.MILLIMETERS;    
myDoc.viewPreferences.verticalMeasurementUnits = MeasurementUnits.MILLIMETERS;  
var W = UnitValue("240mm").as('pt'); ;  
var L = UnitValue("100mm").as('pt');  
app.activeWindow.activePage.resize(CoordinateSpaces.INNER_COORDINATES, AnchorPoint.CENTER_ANCHOR, ResizeMethods.REPLACING_CURRENT_DIMENSIONS_WITH, [W,L]);  
// ----------- Script end -----------  
myDoc.viewPreferences.horizontalMeasurementUnits = savedHorizontalMeasurementUnits;    
myDoc.viewPreferences.verticalMeasurementUnits = savedVerticalMeasurementUnits;

Hi Obi-wan,

in this case changing the viewPreferences is not necessary.

var W = UnitValue("240mm").as('pt');   
var L = UnitValue("100mm").as('pt');
app.activeWindow.activePage.
    resize
    (
        CoordinateSpaces.INNER_COORDINATES,
        AnchorPoint.CENTER_ANCHOR,
        ResizeMethods.REPLACING_CURRENT_DIMENSIONS_WITH,
        [W,L]
    );

You're right! 

Just a habit of systematical work in a "millimeters" context!
