Generate Gradients File
Description
“Generate Gradients File” is a gradients utility script using the JSON Action Manager scripting library.
This stand-alone script written in JavaScript is used to generate a Photoshop gradients file (.grd) from a JSON text file containing a JSON array of gradient objects, each one in Gradient Object Simplified Format.
From a technical point of view, it shows how to take advantage of the method ActionDescriptor.toStream to encode a flattened (serialized) version of an ActionDescriptor object saved in a file.
The utility script Parse Gradients File performs the reverse operation, i.e., converts a Photoshop gradients file (.grd) into a JSON text file containing a JSON array of gradient objects in Gradient Object Simplified Format.
Please refer to the Photoshop Gradients File Format page for detailed information about the structure of a gradients file.
