Revit二次开发--屏幕截图/图片导出

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:\Users\Administrator\Desktop\CurrentViewImg";            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:\Users\Administrator\Desktop\Views\",                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：
