3: Scripting Photoshop

Working with the Photoshop Object Model

OTE

Notification generally does not take effect on events that occur inside of a script, because these

events are embedded with in an

"AdobeScriptAutomation Scripts"

event.

tell application "Adobe Photoshop CS4"

try

delete notifiers

end try

make new notifier with properties {event:"Opn ", ¬

event file:alias "OS X 10.4.8 US:Users:psauto:Desktop:Welcome.jsx"}

end tell

VBS

Dim appRef,eventFile

Set appRef = CreateObject("Photoshop.Application")

appRef.NotifiersEnabled = True

eventFile = appRef.Path & "Presets\Scripts\Event Scripts Only\Welcome.jsx"

appRef.Notifiers.Add "Opn ", eventFile

app.notifiersEnabled = true

var eventFile = new File(app.path +

"/Presets/Scripts/Event Scripts Only/Welcome.jsx")

app.notifiers.add("Opn ", eventFile)

Using the PathItem object

To create a

PathItem

object, you must add a

PathItem

to the

PathItems

element or collection for a

document. This requires that you first create an array of

PathPointInfo

objects, which specify the

coordinates of the corners or anchor points of your path. Then you create an array of

SubPathInfo

objects

to contain the

PathPoint

arrays.Once you have the points and a subpath, you can add a new

PathItem

The following script creates a

PathItem

object that is a straight line.

--line #1--it’s a straight line so the coordinates for anchor, left, and

--right for each point have the same coordinates

tell application "Adobe Photoshop CS4"

set ruler units of settings to pixel units

set type units of settings to pixel units

set docRef to make new document with properties {height:700, width:500, ¬

name:"Snow Cone"}

set pathPointInfo1 to {class:path point info, kind:corner point, ¬

anchor:{100, 100}, left direction:{100, 100}, right direction:{100, 100}}

set pathPointInfo2 to {class:path point info, kind:corner point, ¬

anchor:{150, 200}, left direction:{150, 200}, right direction:{150, 200}}

set subPathInfo1 to ¬

{class:sub path info, ¬

entire sub path:{pathPointInfo1, pathPointInfo2}, ¬

operation:shape xor, closed:false}

set newPathItem to make new path item in docRef with properties ¬

{entire path:{subPathInfo1}, name:"Line", kind:normal}

end tell
