BMPFormat Class
Members  Example 

ArcGIS.Desktop.Mapping Namespace : BMPFormat Class
Represents a Microsoft Windows Bitmap (BMP) object that can be used to export a MapView, MapFrame, or a Layout.
Syntax
public class BMPFormat : ExportFormat 
Public Class BMPFormat 
   Inherits ExportFormat
Remarks
BMP files are simple, native Windows raster images. In general, BMPs are much larger than formats such as JPEG or PNG. They do not scale as well as vector files and may appear blocky or jagged when increased in size. BMPs can be generated with an accompanying world file for use as georeferenced raster data.
Example
The following examples demonstrate how to export a Layout, a MapFrame, and a MapView to BMP format.
//This example demonstrates how to export a layout to BMP.
