Overview

In this lab, you will continue to extend Photoshop using JavaScript. In addition, you will extend Illustrator in much the same manner as you have been with Photoshop.

Procedures

1. Extend Photoshop
   • Walk through this example with the instructor.
   • Open New document and fill the layer with a color
     • If there's not a document open, open one.
       • Set the rulerUnits to PIXELS
       • Add a new document
       • Add an artLayer to the document
     • Detect whether the active layer is the background layer
       • Create a reference to the activeDocument selection
       • Create a new SolidColor
       • Fill the selection with the color
       • Set variables to null
     • If the active layer is the background layer, write out an alert
        
2. Extend Illustrator
   • Walk through this example with the instructor.
   • Create a new swatch, draw a shape, fill it using the swatch
     • Add a new document
     • Create a new CMYKColor
     • Create a new swatch
       • name the swatch
       • store the color in the swatch
     • Create a new star path
       • set the fill and color to use the swatch
          
3. Extend Illustrator
   • Walk through this example with the instructor.
   • Make trees
     • Add a new document - store it as docRef
     • Create a reference to the activeDocument pathItems - piRef
     • for loop (50 or so loops should work)
       • Add a new pathItem - store it as pathRef
       • Copy this code for a tree and paste it next
       • Use Math.random() to randomly change the position of the tree
       • Use Math.random() to randomly scale the tree
       • Use Math.random() to create a random color for the tree
       • Use Math.random() to randomly set the opacity of the tree
          
4. On your own
   • Create a script to accomplish the following in Photoshop:
     • Create a new layer
       • fill the layer with a color
     • Create a new text layer above the other
       • add a drop shadow to the text
     • Merge all layers
     • Apply a blur
        
5. Turn in all scripts.
