I want to make my plotting code faster.

Hi everyone,

I've been receiving amazing help from reading other people's posts on this forum. Thank you!

I've been working on capturing (or taking a screenshot of) specific coordinates using the attached function.

The code works fine, but it's extremely SLOW!!.

I expected it to take less than a second, but it takes at least 10 seconds. It executes all the way down to the "this.Show()" function almost immediately, but generating the actual file takes a long time.

Could you please help me out with this issue?

Thank you in advance!

private void CaptureAndSaveImage(Point3d startPoint, Point3d endPoint, string outputPath) { Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument; Database db = doc.Database; using (DocumentLock docLock = doc.LockDocument()) { // Start a transaction using (Transaction trans = db.TransactionManager.StartTransaction()) { // Get the current layout //Layout layout = trans.GetObject(db.CurrentSpaceId, OpenMode.ForRead) as Layout; BlockTableRecord btr = (BlockTableRecord)trans.GetObject(db.CurrentSpaceId, OpenMode.ForRead); Layout layout = (Layout)trans.GetObject(btr.LayoutId, OpenMode.ForRead); //ObjectId modelSpaceId = SymbolUtilityServices.GetBlockModelSpaceId(db); //Layout layout = trans.GetObject(db.CurrentSpaceId, OpenMode.ForRead) as Layout; // Create a new PlotInfo object PlotSettings plotSettings = new PlotSettings(layout.ModelType); plotSettings.CopyFrom(layout); // Get the PlotSettingsValidator PlotSettingsValidator plotSettingsValidator = PlotSettingsValidator.Current; // Calculate the extents from the two points Extents2d plotWindowExtents = new Extents2d(startPoint.X, startPoint.Y, endPoint.X, endPoint.Y); plotSettings.ScaleLineweights = true; // Set the plot area plotSettingsValidator.SetPlotWindowArea(plotSettings, plotWindowExtents); plotSettingsValidator.SetPlotType(plotSettings, Autodesk.AutoCAD.DatabaseServices.PlotType.Window); plotSettingsValidator.SetUseStandardScale(plotSettings, true); plotSettingsValidator.SetStdScaleType(plotSettings, StdScaleType.ScaleToFit); plotSettingsValidator.SetPlotRotation(plotSettings, PlotRotation.Degrees180); plotSettingsValidator.SetPlotCentered(plotSettings, false); // Set the plot configuration name plotSettingsValidator.SetPlotConfigurationName(plotSettings, "PublishToWeb PNG.pc3", "VGA_(640.00_x_480.00_Pixels)"); //plotSettingsValidator.SetPlotConfigurationName(plotSettings, "AutoCAD PDF (Web and Mobile).pc3", "ISO_A4_(210.00_x_297.00_MM)"); // Update the PlotInfo object with the new settings PlotInfo plotInfo = new PlotInfo(); plotInfo.Layout = btr.LayoutId; plotInfo.OverrideSettings = plotSettings; PlotInfoValidator piv = new PlotInfoValidator(); piv.MediaMatchingPolicy = MatchingPolicy.MatchEnabled; piv.Validate(plotInfo); //// Commit the changes to the transaction trans.Commit(); // Plot the image using (PlotEngine plotEngine = PlotFactory.CreatePublishEngine()) { plotEngine.BeginPlot(null, null); plotEngine.BeginDocument(plotInfo, doc.Name, null, 1, true, Path.Combine("C:\\Users\\YR_VM\\Desktop\\cad backup", Guid.NewGuid() + ".png")); // Define the plot output PlotPageInfo pageInfo = new PlotPageInfo(); try { plotEngine.BeginPage(pageInfo, plotInfo, true, null); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } plotEngine.BeginGenerateGraphics(null); plotEngine.EndGenerateGraphics(null); plotEngine.EndPage(null); plotEngine.EndDocument(null); // End the plot plotEngine.EndPlot(null); } } } this.Show(); }

Plotting would obviously take longer than a graphics dump of the current view.

While output to PDF may not be possible using other means, the code at this link will generate a screenshot.

I am not really great at coding... but the link doesn't seem like I can specify coordinates of objects as my code. Did I understand it wrong? or I can implement that kind of function with the code in the link ??

The code at that link really doesn't specify what to take a snapshot of it just shows how to take a snapshot. So, you would have to first set the view before taking the snapshot through code.
