在Revit API中有一个方法Document.ExportImage(),可以将单个或多个视图导出为图片。
该方法需要传递一个ImageExportOptions类型的参数,在参数中你可以自定义需要导出的视图、图片地址、图片大小等。
单视图导出
using Autodesk.Revit.Attributes;using Autodesk.Revit.DB;using Autodesk.Revit.UI;namespace ScreenShot{ [Transaction(TransactionMode.Manual)] public class Command : IExternalCommand { public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements) { ImageExportOptions options = new ImageExportOptions(); options.ZoomType = ZoomFitType.FitToPage; options.ExportRange = ExportRange.CurrentView; options.FilePath = @"C:UsersAdministratorDesktopCurrentViewImg"; options.FitDirection = FitDirectionType.Horizontal; options.HLRandWFViewsFileType = ImageFileType.JPEGMedium; options.ShadowViewsFileType = ImageFileType.JPEGMedium; options.PixelSize = 1920; commandData.Application.ActiveUIDocument.Document.ExportImage(options); return Result.Succeeded; } }}
上面代码将当前视图以JPG图片的形式导出到桌面上;如果只想截取当前视窗中可见的部分(截图),可将options.ExportRange设置为VisibleRegionOfCurrentView。
多视图导出
using Autodesk.Revit.Attributes;using Autodesk.Revit.DB;using Autodesk.Revit.UI;using System.Collections.Generic;namespace ScreenShot{ [Transaction(TransactionMode.Manual)] public class Command : IExternalCommand { public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements) { Document doc = commandData.Application.ActiveUIDocument.Document; FilteredElementCollector views = new FilteredElementCollector(doc).OfClass(typeof(View)); views.OfCategory(BuiltInCategory.OST_Views); IList<ElementId> ImageExportList = new List<ElementId>(); foreach (View view in views) { if (view.IsTemplate) continue; ImageExportList.Add(view.Id); } var options = new ImageExportOptions { ZoomType = ZoomFitType.FitToPage, PixelSize = 1920, FilePath = @"C:UsersAdministratorDesktopViews", FitDirection = FitDirectionType.Horizontal, HLRandWFViewsFileType = ImageFileType.JPEGMedium, ShadowViewsFileType = ImageFileType.JPEGMedium, ImageResolution = ImageResolution.DPI_300, ExportRange = ExportRange.SetOfViews }; options.SetViewsAndSheets(ImageExportList); doc.ExportImage(options); return Result.Succeeded; } }}
上面代码将项目中所有视图以JPG图片形式导出到桌面Views文件夹中,如下图所示:
