Export Map as PDF in C#?

Rconrad

Is there a way to automatically export a map to a folder as a pdf using an add-in? I have an add-in set up but can't find any documentation for how to accomplish the exporting part. Please let me know if you can help.

P.S: if you have any general tips for learning development with ArcObjects please leave a comment.

-Thanks.

For ExportBMPClass cannot be embedded:

Find ESRI.ArcGIS.Output Reference and view the properties. Set Embed Interop Types to false.

You can remove the VerifyFile type call and just enter the path name and file name of your output BMP into the variable initializers. Then just run a File.Exists on the file name to see if you need to delete it.

The application parameter is the application, in VB you get a handle on it using the code:

My.ArcMap.Application

I don't code in c# but I would imagine its similar? Just look around at some code samples?

Rconrad

Duncan,

Thanks for your response. On the Get ActiveView Snippet, where does the "application" parameter come from? Thanks again.

You need only to scroll down the snippet list and you will discover a function called....

Get ActiveView from ArcMap Snippet

😉

The active view could be either the Map or Layout as indicated by the object model in the help file

Rconrad

That's super helpful, but what do I pass in for the IActiveView parameter when calling the function.

It looks something like this -- CreateJPEGFromActiveView(activeView, @c:\\....)

Thanks @DuncanHornby

D_Hornby_ddh_uni

Here is another code snippet for you to explore this one creating a JPEG. Just a matter of adapting to a PDF format.

Rconrad

Thank you so much for your reply, I just have a few questions though... I keep getting "Interop Type ExportBMPClass cannot be embedded" errors, and I am not sure where the variables "AOUtilities" or "File" come from. Do you have any ideas? Thanks again.

Here is what I use to export to a BMP. There is also an ExportPDFClass() for line 8 with similar functions.

Uses ESRI.ArcGIS.Output

and VerifyFile merely checks if a file is already there and deletes it if it is. Should be fairly easy to reproduce.

Good Luck

            string pathName = "";
            string fileName = "";
            if (AOUtilities.VerifyFile(bmpFile, "bmp", out pathName, out fileName))
                File.Delete(bmpFile);
            IActiveView av = (IActiveView)map;
            IExport pExport = new ExportBMPClass();
            pExport.ExportFileName = bmpFile;
            //pExport.Resolution = 96;
            tagRECT eRect = av.ExportFrame;
