Summary
The BMPFormat object represents a collection of Microsoft Windows bitmap (BMP) file properties that can be configured and used with the export method on the Layout, MapFrame, and MapView objects to create an output BMP file.
Discussion
BMP files are native Windows raster images. BMP files can store pixel data at several bit depths and can be compressed using the lossless RLE method. BMP images are typically much larger than formats such as JPEG or PNG.
The createExportFormat method can be used to create a BMPFormat object if the format parameter is set to BMP. The returned BMPFormat object contains all the properties associated with a generating a BMP file. These properties can be modified accordingly to produce different output results.
Properties
Property | Explanation | Data Type |
clipToElements (Read and Write) | If set to True, include the areas of the page that have map or layout element content only, rather than exporting the entire page. This property only applies when exporting a Layout object. The default value is False. | Boolean |
colorMode (Read and Write) | A string constant that represents the number of bits to describe color in a pixel. The default value is 24-BIT_TRUE_COLOR.
| String |
filePath (Read and Write) | A string that represents the system path and file name, including the extension, for the exported file. | String |
geoReferenceMapFrame (Read and Write) | The MapFrame used to control the coordinate system when the worldFile property is set to True. The default value is None. | MapFrame |
height (Read and Write) | The height, in pixels, of the map area to be exported. This property only applies when exporting a MapView object. The default value is 960. | Double |
resolution (Read and Write) | The effective dpi of the output vector data. The default value is 96. Note:When exporting a MapView, the dpi is calculated automatically using system dpi scaling and therefore this value will be ignored. | Integer |
showSelectionSymbology (Read and Write) | Show selected features in the map or map frame as selected in the output file. Setting this value to False does not affect selection within the view, only in the output file. The default value is False. | Boolean |
threshold (Read and Write) | Image intensities set above this value will appear white in the output file and all other values will appear black. This property is applied only when the colorMode property is set to 1-BIT_MONOCHROME_THRESHOLD. The default value is 128. | Boolean |
width (Read and Write) | The width, in pixels, of the map area to be exported. This property only applies when exporting a MapView object. The default value is 960. | Double |
worldFile (Read and Write) | If set to True and a valid georef_mapframe is set, a world file will be generated based on the map frame's coordinate system. The default value is False. | Boolean |

Code sample
The following script exports a layout to BMP format using default property values.
p = arcpy.mp.ArcGISProject('current')
lyt = p.listLayouts()[0]
bmp = arcpy.mp.CreateExportFormat('BMP', r'C:\Temp\output.bmp')
lyt.export(bmp)
