Adobe Smoke Alarm CS3 Manuale Utente

 Scripting Photoshop CS3     59

The unit type settings of the two Photoshop CS3 rulers control how numbers are interpreted when dealing 
with properties and parameters that support unit values. Be sure to set the ruler units as needed at the 
beginning of your scripts and save and restore the original ruler settings when your script has completed.

In AppleScript 

ruler units

 and 

type units

 are properties of the 

settings-object

, accessed through 

the Application object's

 settings 

property as shown below.

set ruler units of settings to inch units
set type units of settings to pixel units
set point size of settings to postscript size

In VBScript 

RulerUnits 

and 

TypeUnits

 are properties of the 

Preferences

 object, accessed through the 

Application

 object's

appRef.Preferences.RulerUnits = 2 'for PsUnits --> 1 (psInches)
appRef.Preferences.TypeUnits = 1 'for PsTypeUnits --> 1 (psPixels)
appRef.Preferences.PointSize = 2 
'2 indicates psPointType --> 2 (PsPostScriptPoints)

In JavaScript 

rulerUnits 

and 

typeUnits

 are properties of the
