添加水平渐变
Aspose.Page for .NET 提供了 XpsGradientBrush 类，您可以使用它在 XPS 文档中添加渐变。
您需要指定 XpsGradientStop 并将 XpsPath 添加到 XpsDocument 类的对象。
以下代码片段展示了在 XPS 文档中添加水平渐变的完整功能：
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 List<XpsGradientStop>();
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.RenderTransform = doc.CreateMatrix(1f, 0f, 0f, 1f, 20f, 70f);
19path.Fill = doc.CreateLinearGradientBrush(new PointF(10f, 0f), new PointF(228f, 0f));
20((XpsGradientBrush)path.Fill).GradientStops.AddRange(stops);
21// Save resultant XPS document
22doc.Save(OutputDir + outputFileName);结果
添加垂直渐变
Aspose.Page for .NET 提供了 XpsGradientBrush 类，您可以使用它在 XPS 文档中添加渐变。您需要指定 XpsGradientStop 并将 XpsPath 添加到 XpsDocument 类的对象。 以下代码片段展示了在 XPS 文档上添加垂直渐变的完整功能：
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";
7
8// Initialize List of XpsGradentStop
9List<XpsGradientStop> stops = new List<XpsGradientStop>();
10stops.Add(doc.CreateGradientStop(doc.CreateColor(253, 255, 12, 0), 0f));
11stops.Add(doc.CreateGradientStop(doc.CreateColor(252, 255, 154, 0), 0.359375f));
12stops.Add(doc.CreateGradientStop(doc.CreateColor(252, 255, 56, 0), 0.424805f));
13stops.Add(doc.CreateGradientStop(doc.CreateColor(253, 255, 229, 0), 0.879883f));
14stops.Add(doc.CreateGradientStop(doc.CreateColor(252, 255, 255, 234), 1f));
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.RenderTransform = doc.CreateMatrix(1f, 0f, 0f, 1f, 20f, 70f);
18path.Fill = doc.CreateLinearGradientBrush(new PointF(10f, 110f), new PointF(10f, 200f));
19((XpsGradientBrush)path.Fill).GradientStops.AddRange(stops);
20// Save resultant XPS document
21doc.Save(OutputDir + outputFileName);结果
添加对角渐变
Aspose.Page for .NET 提供了 XpsGradientBrush 类，您可以使用它在 XPS 文档中添加渐变。为此，首先指定 XpsGradientStop，然后将 XpsPath 添加到 XpsDocument 类的对象。以下代码片段展示了在 XPS 文档中添加对角渐变的完整功能：
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 List<XpsGradientStop>();
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.RenderTransform = doc.CreateMatrix(1f, 0f, 0f, 1f, 20f, 70f);
22path.Fill = doc.CreateLinearGradientBrush(new PointF(10f, 10f), new PointF(228f, 100f));
23((XpsGradientBrush)path.Fill).GradientStops.AddRange(stops);
24// Save resultant XPS document
25doc.Save(OutputDir + outputFileName);结果
