Save a viewpoint as a local jpg image with Redlines using NET API

[Gangula2]

Is there a way to use .NET API to save a savedviewpoint as a JPG image along with the redlines?

I was able to fid this link which refers to an article that talks about how to do it using COM API. Is the same possible using .NET API?

// COM API Code

[PluginAttribute("VPtoIMG",
//4 character Developer ID or GUID
"Gangula",
//The tooltip for the item in the ribbon
ToolTip = "Save viewpoint to jpg images",
//Display name for the Plugin in the Ribbon
DisplayName = "Viewpoint to IMG")]
public class SavedVP2IMG : AddInPlugin
{
// execute the plug-in command
public override int Execute(params string[] parameters)
{
    // export the saved viewpoints to images
    dumpSavedVP();
    return 0;
}

#region "produce images"
//locations to export the images
static string _snapshos_location = "c:\\temp\\";
// array of names of the saved viewpoints
List<string> _fileArray = new List<string>();

// export the saved viewpoints to images

private void dumpSavedVP()
{
    // get the active document
    Document oDoc = Autodesk.Navisworks.Api.Application.ActiveDocument;
    // get the state of COM
    ComApi.InwOpState10 oState = ComBridge.State;
    // get the IO plugin for image
    ComApi.InwOaPropertyVec options = oState.GetIOPluginOptions("lcodpimage");

    // configure the option "export.image.format"
    //to export png

    foreach (ComApi.InwOaProperty opt in options.Properties())
    {
        if (opt.name == "export.image.format")
            opt.value = "lcodpexpng";
        if (opt.name == "export.image.width")
            opt.value = 1600;
        if (opt.name == "export.image.height")
            opt.value = 900;
    }

    // swtich to the saved viewpoint
    foreach (SavedViewpoint oSVP in
        oDoc.SavedViewpoints.ToSavedItemCollection())
    {
        string svpName = oSVP.DisplayName;
        oDoc.SavedViewpoints.CurrentSavedViewpoint = oSVP;
        // set the current viewpoint  oDoc.SavedViewpoints.CurrentSavedViewpoint = oSVP; 
        // the image name
        string tempFileName = _snapshos_location + svpName + ".png";

        // delete the existing image if there is.
        if (System.IO.File.Exists(tempFileName))
            System.IO.File.Delete(tempFileName);
        try
        {
            //export the viewpoint to the image
            oState.DriveIOPlugin("lcodpimage", tempFileName, options);
            System.Drawing.Bitmap oBitmap = new System.Drawing.Bitmap(tempFileName);
            System.IO.MemoryStream ImageStream = new System.IO.MemoryStream();
            oBitmap.Save(ImageStream, System.Drawing.Imaging.ImageFormat.Jpeg);

            // add the image name to the list for use
            //of uploading to cloud
            _fileArray.Add(svpName);
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.ToString());
        }
    }
}

Hi @Gangula2 ,

Could you please take a look at the below link?

Thank you for sharing this Naveen.

The link you shared refers to COM API. can you please point me to  the answer you're referring to?

Hi @Gangula2 ,

Please take a look at this below sample code

public void ExportViewPointAsImage()
       {
            string path = @"....\ImageJpg.jpg";
            Autodesk.Navisworks.Api.View currentView = Application.ActiveDocument.ActiveView;
            Bitmap bmp = Application.ActiveDocument.ActiveView.GenerateImage(ImageGenerationStyle.ScenePlusOverlay, currentView.Width, currentView.Height);
            bmp.Save(path);
       } 

Get all the viewpoints and make each viewpoint as the current viewpoint(so that redlines will be visible in the view) and export the image

SavedViewpoint iteratedView = savedItem as SavedViewpoint;
SavedViewpoint current = Application.ActiveDocument.SavedViewpoints.CurrentSavedViewpoint as SavedViewpoint;
Application.ActiveDocument.SavedViewpoints.CurrentSavedViewpoint = iteratedView;

Thank you Naveen. That worked for me.
