在 XPS 文件中使用可视化画笔 | Java

使用可视化画笔添加网格

Aspose.Page for Java 提供了 XpsVisualBrush 类，您可以使用它在 XPS 文档上添加网格。您需要指定 XpsPathGeometry 并将 XpsCanvas 添加到 XpsDocument 类的对象中。以下代码片段展示了在 XPS 文档上添加网格的完整功能：

// Add grid with visual brush to XPS document.

XpsDocument doc = new XpsDocument();

String outputFileName = "AddGrid_out.xps";

// Geometry for magenta grid VisualBrush
XpsPathGeometry pathGeometry = doc.createPathGeometry();
Point2D.Float[] points = new Point2D.Float[] { 
    new Point2D.Float(240f, 5f), 
    new Point2D.Float(240f, 310f), 
    new Point2D.Float(0f, 310f) 
};
pathGeometry.addSegment(doc.createPolyLineSegment(points));
pathGeometry.getPathFigures().get(0).setStartPoint(new Point2D.Float(0f, 5f));

// Canvas for magenta grid VisualBrush
XpsCanvas visualCanvas = doc.createCanvas();

XpsPath visualPath = visualCanvas.addPath(
    doc.createPathGeometry("M 0,4 L 4,4 4,0 6,0 6,4 10,4 10,6 6,6 6,10 4,10 4,6 0,6 Z"));
visualPath.setFill(doc.createSolidColorBrush(doc.createColor(1f, .61f, 0.1f, 0.61f)));

XpsPath gridPath = doc.createPath(pathGeometry);
//Create Visual Brush, it is specified by some XPS fragment (vector graphics and glyphs)
gridPath.setFill(doc.createVisualBrush(visualCanvas,
    new Rectangle2D.Float(0f, 0f, 10f, 10f), new Rectangle2D.Float(0f, 0f, 10f, 10f)));
((XpsVisualBrush)gridPath.getFill()).setTileMode(XpsTileMode.Tile);

// New canvas
XpsCanvas canvas = doc.addCanvas();
canvas.setRenderTransform(doc.createMatrix(1f, 0f, 0f, 1f, 268f, 70f));
// Add grid
canvas.addPath(pathGeometry);
// Red transparent rectangle in the middle top
XpsPath path = canvas.addPath(doc.createPathGeometry("M 30,20 l 258.24,0 0,56.64 -258.24,0 Z"));
path = canvas.addPath(doc.createPathGeometry("M 10,10 L 228,10 228,100 10,100"));
path.setFill(doc.createSolidColorBrush(doc.createColor(1.0f, 0.0f, 0.0f)));
path.setOpacity(0.7f);
// Save resultant XPS document
doc.save(getOutputDir() + outputFileName);
