How to change the gradient length?

[AnyON]

Hi all

A radial gradient of two colors, black and white, is applied to the object as a fill color.
By default, the length of the gradient is from the starting point in the middle of the bounding box to the ending point at the edge of the bounding box. How can I change this length using script commands?

 

when you change this length manually, and then using the command
var L = item.fillColor.length
you get this value (72.236), then the expected result is displayed.

But the commander is like item.fillColor.length = 152 does not change this length???

It's a bug. A gradient's origin, length and angle cannot be overwritten.

Here's an elaborate workaround courtesy of CarlosCanto. This doubles a gradient's length (of a selected item) in the right direction:

var fillcolor = app.selection[0].fillColor;
app.selection[0].filled = false;
app.selection[0].fillColor = fillcolor;
app.selection[0].fillOverprint = app.selection[0].fillOverprint;
var f = app.getScaleMatrix(200, 100);  // double x
app.selection[0].transform(
    f, false, false, true, false, 0, Transformation.LEFT);
