Adobe InDesign CS2 Scripting Guide Working with Documents in JavaScript 119 Setting grid preferences To control the properties of the document and baseline grid, you set the properties of the gridPreferences object, as shown in the following script: //DocumentAndBaselineGrids.jsx //An InDesign CS2 JavaScript //Creates a document, then sets preferences for the //document grid and baseline grid. var myDocument = app.documents.add(); //Set the document measurement units to points. myDocument.viewPreferences.horizontalMeasurementUnits = MeasurementUnits.points; myDocument.viewPreferences.verticalMeasurementUnits = MeasurementUnits.points; //Set up grid preferences. with(myDocument.gridPreferences){ baselineStart = 56; baselineDivision = 14; baselineShown = true; horizontalGridlineDivision = 14; horizontalGridSubdivision = 5 verticalGridlineDivision = 14; verticalGridSubdivision = 5 documentGridShown = true; } Snapping to guides and grids All the snap settings for the grids and guides of a document are in the properties of the guidePreferences and gridPreferences objects. Here's an example: //GuideAndGridPreferences.jsx //An InDesign CS2 JavaScript //Sets preferences for guides and grids. //Assumes you have a document open. var myDocument = app.activeDocument; with(myDocument.guidePreferences){ guidesInBack = true; guidesLocked = false; guidesShown = true; guidesSnapTo = true; } with(myDocument.gridPreferences){ documentGridShown = false; documentGridSnapTo = true; //Objects "snap" to the baseline grid when //guidePreferences.guideSnapTo is set to true. baselineGridShown = true; } Changing measurement units and ruler The example scripts so far used measurement strings (strings that force InDesign to use a specific measurement unit, "8.5i", for example, for 8.5 inches). They do this because you might be using a different measurement system when you run the script. To specify the measurement system used in a script, use the document's viewPreferences object. //ViewPreferences.jsx //An InDesign CS2 JavaScript //Changes the measurement units used by the active document. //Assumes you have a document open. var myDocument = app.activeDocument; with(myDocument.viewPreferences){
