CHAPTER 5: Scripting with JavaScript Working with the perspective grid 52

Use perspective presets

Illustrator provides default grid-parameter presets for one-point, two-point, and three-point perspectives.

The presets are named

"[1P-NormalView]", "[2P-NormalView]", and "[3P-NormalView]".

This script shows how to select a preset programmatically:

//Set the default one-point perspective preset

app.activeDocument.selectPerspectivePreset("[1P-Normal View]");

//Set the default two-point perspective preset

app.activeDocument.selectPerspectivePreset("[2P-Normal View]");

//Set the default three-point perspective preset

app.activeDocument.selectPerspectivePreset("[3P-Normal View]");

You can create new perspective presets, export presets to files, and import presets from files. These scripts

shows how to export and import presets:

//Create a new document

var mydoc = app.documents.add();

//Export perspective presets to a file

var exportPresetFile = new File("C:/scripting/PGPresetsExported")

mydoc.exportPerspectiveGridPreset(exportPresetFile);

//Create a new document

var mydoc = app.documents.add();

//Import perspective presets from a file

var importPresetFile = new File("C:/scripting/PGPresets")

mydoc.importPerspectiveGridPreset(importPresetFile);

Show or hide the grid

This script shows or hides the Perspective Grid programmatically:

//Show the Perspective Grid defined in the document

app.activeDocument.showPerspectiveGrid();

//Hide the Perspective Grid defined in the document

mydoc.hidePerspectiveGrid();

Set the active plane

The perspective grid plane types are:

For a one-point perspective grid, only the left and floor plane are valid.

This script sets the active perspective plane:

Left plane

PerspectiveGridPlaneType.LEFTPLANE

Right plane

PerspectiveGridPlaneType.RIGHTPLANE

Floor plane

PerspectiveGridPlaneType.FLOORPLANE

Invalid plane

PerspectiveGridPlaneType.NOPLANE
