Exports the viewer content into the image file. Prepared to export even very big images by exporting in tiles.

Pseudo code:

// prepare output layer
lp = (TGIS_LayerPixel)TGIS_Utils.GisCreateLayer('', path);
 
// prepare subformat specification to use layer default encoding
// you can also use TGIS_LayerPixel.Capabilities to learn about
// other possibilites.
subformat = new TGIS_LayerPixelSubFormat(
                  TGIS_PixelFormat.RGB, 
                  false, 
                  TGIS_PixelSubFormat.None, 
                  TGIS_CompressionType.None, 
                  100
                ) ;
 
// build output layer
lp.Build( lp.Path, false, GIS.CS, GIS.Extent, width, height, subformat);
 
// create export manager
export = new TGIS_PixelExportManager( lp );
export.BusyEvent = my_busy_event;
 
// create temporary viewer to be used for tiling
tile = new TGIS_ViewerBmp();
 
// perform export
export.ExportFrom( GIS, tile, GIS.Extent, dpi );
 
// finalize save
lp.SaveData()
