Add Horizontal Gradient
Aspose.Page for Java offers XpsGradientBrush Class, with which you can add gradient on XPS document. You need to specify XpsGradientStop and add XpsPath to the object of XpsDocument class. The following code snippet shows complete functionality to add horizontal gradient on an XPS document:
The result
1// Paint rectangle with horizontal gradient fill in XPS document.
2
3// Create new XPS Document
4XpsDocument doc = new XpsDocument();
5
6String outputFileName = "HorizontalGradient_outXPS.xps";
7
8// Initialize List of XpsGradentStop
9List<XpsGradientStop> stops = new ArrayList<>();
10stops.add(doc.createGradientStop(doc.createColor(255, 244, 253, 225), 0.0673828f));
11stops.add(doc.createGradientStop(doc.createColor(255, 251, 240, 23), 0.314453f));
12stops.add(doc.createGradientStop(doc.createColor(255, 252, 209, 0), 0.482422f));
13stops.add(doc.createGradientStop(doc.createColor(255, 241, 254, 161), 0.634766f));
14stops.add(doc.createGradientStop(doc.createColor(255, 53, 253, 255), 0.915039f));
15stops.add(doc.createGradientStop(doc.createColor(255, 12, 91, 248), 1f));
16// Create new path by defining geometery in abbreviation form
17XpsPath path = doc.addPath(doc.createPathGeometry("M 10,210 L 228,210 228,300 10,300"));
18path.setRenderTransform(doc.createMatrix(1f, 0f, 0f, 1f, 20f, 70f));
19path.setFill(doc.createLinearGradientBrush(new Point2D.Float(10f, 0f), new Point2D.Float(228f, 0f)));
20((XpsGradientBrush)path.getFill()).getGradientStops().addAll(stops);
21// Save resultant XPS document
22doc.save(getOutputDir() + outputFileName);Add Vertical Gradient
Aspose.Page for Java offers XpsGradientBrush Class, with which you can add gradient on XPS document. You need to specify XpsGradientStop and add XpsPath to the object of XpsDocument class. The following code snippet shows complete functionality to add vertical gradient on an XPS document:
The result
1// Paint rectangle with vertical gradient fill in XPS document.
2
3// Create new XPS Document
4XpsDocument doc = new XpsDocument();
5
6String outputFileName = "VerticalGradient_outXPS.xps";

8// Initialize List of XpsGradentStop

15// Create new path by defining geometery in abbreviation form
16XpsPath path = doc.addPath(doc.createPathGeometry("M 10,110 L 228,110 228,200 10,200"));
17path.setRenderTransform(doc.createMatrix(1f, 0f, 0f, 1f, 20f, 70f));
18path.setFill(doc.createLinearGradientBrush(new Point2D.Float(10f, 110f), new Point2D.Float(10f, 200f)));

20// Save resultant XPS document
21doc.save(getOutputDir() + outputFileName);Add Diagonal Gradient
Aspose.Page for Java offers XpsGradientBrush Class, with which you can add gradient on XPS document. You need to specify XpsGradientStop and add XpsPath to the object of XpsDocument class. The following code snippet shows complete functionality to add a linear gradient on an XPS document:
1// Paint rectangle with diagonal gradient fill in XPS document.
2
3// Create new XPS Document
4XpsDocument doc = new XpsDocument();
5
6String outputFileName = "DiagonalGradient_outXPS.xps";
7
8// Initialize List of XpsGradentStop
9List<XpsGradientStop> stops = new ArrayList<>();
10// Add Colors to Gradient
11stops.add(doc.createGradientStop(doc.createColor(0, 142, 4), 0f));
12stops.add(doc.createGradientStop(doc.createColor(255, 202, 0), 0.144531f));
13stops.add(doc.createGradientStop(doc.createColor(255, 250, 0), 0.264648f));
14stops.add(doc.createGradientStop(doc.createColor(255, 0, 0), 0.414063f));
15stops.add(doc.createGradientStop(doc.createColor(233, 0, 255), 0.544922f));
16stops.add(doc.createGradientStop(doc.createColor(107, 27, 190), 0.694336f));
17stops.add(doc.createGradientStop(doc.createColor(63, 0, 255), 0.844727f));
18stops.add(doc.createGradientStop(doc.createColor(0, 199, 80), 1f));
19// Create new path by defining geometery in abbreviation form
20XpsPath path = doc.addPath(doc.createPathGeometry("M 10,10 L 228,10 228,100 10,100"));
21path.setRenderTransform(doc.createMatrix(1f, 0f, 0f, 1f, 20f, 70f));
22path.setFill(doc.createLinearGradientBrush(new Point2D.Float(10f, 10f), new Point2D.Float(228f, 100f)));
23((XpsGradientBrush)path.getFill()).getGradientStops().addAll(stops);
24// Save resultant XPS document
25doc.save(getOutputDir() + outputFileName);The result
