How to get or set units?!

[photogyulai]

Hey Guys!

I have some extensions that measure the width and height...

but if the

Edit menu>> preferences >> units are in centimeter

the result of the measurement will be faaaarrr different than in pixels

like:

43 in cm

500000 in pixels...

is there any option for getting the units type or setting it permanently or temporarly?!?

I found this one but it didnt do anything:

app.scriptPreference.measurementUnit = app.MeasurementUnits.PIXELS;

any help would be appreciated!!

Thanks!!

Ben

app.preferences.rulerUnits = Units.PIXELS;//sets the units to pixels
var whatUnits = app.preferences.rulerUnits;//gets whatever the current units are.

Bonjour

Try this :

#target photoshop

var startRulerUnits = app.preferences.rulerUnits
var startTypeUnits = app.preferences.typeUnits
var startDisplayDialogs = app.displayDialogs
app.preferences.rulerUnits = Units.PIXELS
app.preferences.typeUnits = TypeUnits.PIXELS

//Passage en mm
app.preferences.typeUnits = TypeUnits.MM //MM et non CM
app.preferences.rulerUnits = Units.CM //ou MM
app.displayDialogs = DialogModes.NO

alert( app.activeDocument.width )

//Retour aux reglages d origine
app.preferences.rulerUnits = startRulerUnits
app.preferences.typeUnits = startTypeUnits

The "Photoshop Scriptref.pdf" has sample scripts. You can also look at scripts that come with PS for how things are done.
