Working with Gradient in XPS file | Python
A gradient is a gradual transition between two or more colors or shades. In visual arts, graphics, and design, gradients are often used to create smooth transitions from one color to another, adding depth, dimension, and visual interest to an object or image. Gradients can vary in complexity, from simple two-color gradients to more intricate blends involving multiple colors or even transparency levels.
Here you will find out how to add different types of gradients to XPS files in Python.
Add Gradient in XPS Document
Add Horizontal Gradient
Aspose.Page for Python via .NET provides the XpsGradientBrush Class, created to incorporate gradients into XPS documents. To achieve this, you must specify XpsGradientStop and add XpsPath to the object of the XpsDocument class. The following code snippet demonstrates the complete functionality for adding a horizontal gradient to an XPS document:

Aspose.Page for Python via .NET includes the XpsGradientBrush Class, for incorporating gradients into XPS documents. To accomplish this, you must specify XpsGradientStop and add XpsPath to the object of XpsDocument class. The following code snippet demonstrates the complete functionality for adding a vertical gradient to an XPS document:
