CHAPTER 3: Documents Basic Page Layout 27
var myDocument = app.documents.add();
var myPageWidth = myDocument.documentPreferences.pageWidth;
var myPageHeight = myDocument.documentPreferences.pageHeight;
with(myDocument.pages.item(0)){
//Place guides at the margins of the page.
guides.add(undefined, {orientation:HorizontalOrVertical.vertical, <lb>
location:marginPreferences.left});
guides.add(undefined, {orientation:HorizontalOrVertical.vertical, <lb>
location:(myPageWidth - marginPreferences.right)});
guides.add(undefined, {orientation:HorizontalOrVertical.horizontal, <lb>
location:marginPreferences.top});
guides.add(undefined, {orientation:HorizontalOrVertical.horizontal, <lb>
location:(myPageHeight - marginPreferences.bottom)});
//Place a guide at the vertical center of the page.
guides.add(undefined, {orientation:HorizontalOrVertical.vertical, <lb>
location:(myPageWidth/2)});
//Place a guide at the horizontal center of the page.
guides.add(undefined, {orientation:HorizontalOrVertical.horizontal, <lb>
location:(myPageHeight/2)});
}
You also can create guides using the createGuides method on spreads and master spreads, as shown in
the following script fragment (from the CreateGuides tutorial script):
var myDocument = app.documents.add();
with (myDocument.spreads.item(0)){
//Parameters (all optional): row count, column count, row gutter,
//column gutter,guide color, fit margins, remove existing, layer.
//Note that the createGuides method does not take an RGB array
//for the guide color parameter.
createGuides(4, 4, "1p", "1p", UIColors.gray, true, true,
myDocument.layers.item(0));
}
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 fragment (from the DocumentAndBaselineGrid
tutorial script):
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;
}
