Thanks, Charles. .GetViewSize() is what I needed, but I still had to implement the 'cheat' above to get anything that resembled the actual mapview aspect ratio without truncating it. (This interface won't let me attach images above 1920x1080.) I believe this method would ALSO work if the user merely wanted a low-res screenshot--just delete the *3 multipliers from resolution, height, width. Here's where I ended up:
---------------------------------------------------------------------------------
private async void Xprt_mv_Click(object sender, EventArgs e)
{
await ActMap();
if (File.Exists(GVar.DL + @"temp\MapView.tiff"))
{
File.Delete(GVar.DL + @"temp\MapView.tiff");
}
if (File.Exists(GVar.DL + @"temp\MapView.tfw"))
{
File.Delete(GVar.DL + @"temp\MapView.tfw");
}
await QueuedTask.Run(() =>
{
MapView activeMapView = MapView.Active;
var mvs = activeMapView.GetViewSize(); //get active mapview size
double mvsh = (mvs.Height)*3; //set height variable *3 for printable resolution
double mvsw = (mvs.Width)*3; //set width variable *3 for printable resolution
int ResoMultiplied = 96 * 3; //native System display resolution 96ppi *3 for printable resolution
if (activeMapView != null)
{
TIFFFormat Tiff = new TIFFFormat()
{
Resolution = ResoMultiplied, //use resolution multiplied
Height = mvsh, //use height variable
Width = mvsw, //use width variable
HasWorldFile = true,
OutputFileName = GVar.DL + @"temp\MapView.tiff"
};
//Export active map view
if (Tiff.ValidateOutputFilePath())
{
activeMapView.Export(Tiff);
}
try
{
string filepath = GVar.DL + @"temp\";
Process.Start(filepath);
}
catch (Exception)
{
MessageBox.Show("Could not open the image's containing folder because it does not exist.", " Missing FilePath",
MessageBoxButtons.OK,
MessageBoxIcon.Warning,
MessageBoxDefaultButton.Button1,
MessageBoxOptions.DefaultDesktopOnly);
return;
}
// emf, eps, gif, jpeg, pdf, png, svg, tga, tiff formats also available for export
}
});
}
