MakeRadialGradient.jsx

DESCRIPTION

This Sample creates a radial gradient and adds it to the Swatches 
palette then applies it to a new path item in a new document.
It shows the use of the PathItems and GradientStops collections, 
RGBColor, Gradient and GradientStop objects.

**********************************************************/

// Open a new document
var docRef = app.documents.add();

// Create a new path item in the new document
var pathRef = docRef.pathItems.rectangle (700, 100, 300, 300, false);

// Call createGradient function to create gradient myGradient
var myGradient = createGradient();

// Apply gradient myGradient new path item
pathRef.filled = true;
pathRef.fillColor = myGradient;
redraw();
