Hi Andre
There are a couple ways by which you can accomplish what you need:
1. Make a new Layout in your project. Add a Map frame to your layout. Define the map you want within that map frame. You can then use the following code snippet (also available in the API Reference guide here) to export the map as a PNG file:
//This example demonstrates how to export an individual map frame on a layout to PNG.
//Added references
using ArcGIS.Desktop.Core; //Project
using ArcGIS.Desktop.Layouts; //Layout classes
using ArcGIS.Desktop.Framework.Threading.Tasks; //QueuedTask
using ArcGIS.Desktop.Mapping; //Export formats
public class ExportMapFrameToPNGExample
{
public static Task ExportMapFrameToPNGAsync(string LayoutName, string MFName, string Path)
{
//Reference a layoutitem in a project by name
LayoutProjectItem layoutItem = Project.Current.GetItems<LayoutProjectItem>().FirstOrDefault(item => item.Name.Equals(LayoutName));
if (layoutItem == null)
return Task.FromResult<Layout>(null);
//Create PNG format with appropriate settings
PNGFormat PNG = new PNGFormat();
PNG.Resolution = 300;
PNG.OutputFileName = Path;
return QueuedTask.Run(() =>
{
//Export MapFrame
Layout lyt = layoutItem.GetLayout(); //Loads and returns the layout associated with a LayoutItem
MapFrame mf = lyt.FindElement(MFName) as MapFrame;
PNG.OutputFileName = Path;
if (PNG.ValidateOutputFilePath())
{
mf.Export(PNG);
}
});
}
}
2. If you want your add-in to display Pro's "Export Map" dialog, you can use the following code snippet to execute an ICommand using IPlugInWrapper. This snippet can be added to a button's click handler, for example:
internal class Button1 : Button
{
protected override void OnClick()
{
IPlugInWrapper wrapper = FrameworkApplication.GetPlugInWrapper("esri_sharing_ExportMap"); // Export Map button's ID.
var command = wrapper as ICommand; // tool and command(Button) supports this
if ((command != null) && command.CanExecute(null))
command.Execute(null);
}
}
