新添加图层的插入物着色

如何为新添加的图层着色插入物 (CADNET-1146)

问题： 如何为新添加的图层着色插入物 (CADNET-1146)。

提示： 为此，使用 CadLayerTable 类创建一个图层，以便能够将新图层添加到绘图中，您还可以使用 CadLayersList 添加多个图层。

示例：

初始文件包含5个名称为“1”，“2”，“3”，“4”和“5”的插入物，所有这些都在默认的0图层中。

using (CadImage cadImage = (CadImage)Image.Load(GetPath(fileName)))
{
  CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
  rasterizationOptions.DrawType = CadDrawTypeMode.UseObjectColor;
  
  CadLayersList newList = cadImage.Layers;

  CadLayerTable redLayer = new CadLayerTable();
  redLayer.Name = "REDLAYER";
  redLayer.ColorId = 1; // ID of red color               
  redLayer.ObjectHandle = "REDLAYER";
  
  CadLayerTable greenLayer = new CadLayerTable();
  greenLayer.Name = "GREENLAYER";
  greenLayer.ObjectHandle = "GREENLAYER";
  greenLayer.ColorId = 3; // ID of green color
  
  newList.AddRange(new CadLayerTable[] {redLayer, greenLayer});
  
  cadImage.Layers = newList;
  foreach (CadBaseEntity entity in cadImage.Entities)
  {
    if (entity.TypeName == CadEntityTypeName.INSERT)
    {
      CadInsertObject insert = (CadInsertObject)entity;
  
      // the required block to change color for is identified by name
      if (insert.Name == "3")
      {
      insert.LayerName = "REDLAYER";
      }
  
      if (insert.Name == "2")
      {
      insert.LayerName = "GREENLAYER";
      }
    }
  }
  
  PdfOptions pdfOptions = new PdfOptions();
  pdfOptions.VectorRasterizationOptions = rasterizationOptions;

  cadImage.Save(outPath, pdfOptions);
}
