Question

JavaScripting for Warp

  • August 4, 2015

Hello,

This will be my first time using JavaScript. I'm trying to make a movie made up of several frames in photoshop, and then using timeline to view them. I would like to write a script to make hundreds of small distortions using the Transform, Warp. I would want the final to look like an animation as if I was dragging several of the pins in warp around at once.

How would I go about writing a script for that?

So have you been able to make any progress on the issue?

Here is an example of code that warps the active Layer thusly (naturally the active Layer should be a Smart Object):

// 2015, use it at your own risk;


#target photoshop


if (app.documents.length > 0) {


// set to pixels;


var originalRulerUnits = app.preferences.rulerUnits;


app.preferences.rulerUnits = Units.PIXELS;


// warp;


warpThis ([[0,0], [33.3333333,50], [66.6666667,0], [100,0], [0,33.3333333], [33.3333333,33.3333333], [66.6666667,33.3333333], [100,33.3333333], [0,66.6666667], [33.3333333,66.6666667], [66.6666667,66.6666667], [100,66.6666667], [0,100], [33.3333333,100], [66.6666667,100], [100,100]], [0,0]);


// reset;


app.preferences.rulerUnits = originalRulerUnits;


};


////// warp //////

    This will be my first time using JavaScript.

    Then I think you might be "trying to run before you have learned to walk".

    Warp can be Scripted but needs Action Manager (AM) code and for beginners it might be easier to start with Document Object Model (DOM) code as that is in some ways more easily readable.

    The warping code can be wrapped in a function that takes 16 points (defined as an Array of horizontal and vertical positions) as arguments, but Scripting the animation aspects may also be a bit involved for a first project.

    I would like to write a script to make hundreds of small distortions using the Transform, Warp.

    How do you want to define those transformation values anyway?
