Class: McDbHatch

2d.McDbHatch

表示图案填充类，实现实心颜色填充和各种图案填充效果

Example

  import { MxCADUiPrPoint, MxCADUtility, McDbHatch, MxCpp, McDb, McCmColor} from "mxcad"
  //选点填充
   const getPoint = new MxCADUiPrPoint();
   console.log("\n指定填充区域内部一点:");
   let pt = (await getPoint.go()) as McGePoint3d;
   if (!pt) return;

   let hatch:McDbHatch = MxCADUtility.builderHatchFromPoint(pt);
   if (!hatch) {
       console.log("没有找到闭合区域\n")
       return;
   }
   // 清除填充图案效果
   hatch.clearPatternDefinition();
   // 添加图案填充定义
   hatch.addPatternDefinition(45, 1, 1, 1, 0.25, [45, 0.17677695, 0, 0, 0.25, 0.125, -0.0625])
   // 设置填充图案
   hatch.setPattern(McDb.HatchPatternType.kCustomDefined, 'test')
   // 设置填充颜色
   hatch.trueColor = new McCmColor(0, 133, 122)
   // 绘制填充对象
