Summary
The MapFrame object is a layout element that is used to display the contents of a map. It also provides access to layout size, positioning on the layout, basic navigation methods, and export options.
Discussion
A MapFrame is a layout element that displays the geographic information added to a map. The listElements method on the Layout object returns a Python list of layout elements. To return a list of only map frames, use the MAPFRAME_ELEMENT constant for the element_type parameter. A wildcard can also be used to further refine the search based on the element's name.
The createMapFrame method on the Layout class will also return a map frame reference.
Once a MapFrame is referenced, the properties and methods allow you to do a variety of operations. First, There are basic properties that allow your to control the size, positioning, and visibility of the map frame on the layout. Second, there are several navigation methods such as panToExtent, zoomToAllLayers, and zoomToBookmark that allow you to modify the area of interest that is displayed in the map frame. Third, the map property allows you to change or get access to the associated map. From here, you can directly manage the layers, tables and basemaps in the map and also get access to the map's camera information, which allows you to modify the area of interest even more. You can switch maps of the same dimension or different dimensions. Finally, there are a number of export methods that allow you to export the map frame into a variety of export formats.
Tip:
Exporting a MapFrame on a layout will produce more consistent results than trying to export a MapView outside of the application. A limitation of exporting a MapView is that map views only work with Python scripts run inside of the application. This is because the size of the window and the area of interest is only known when the application and its view panes are open.MapFrame export has all of the sizing information persisted in the element so scripts run from inside the application or run as stand-alone scripts outside the application will produce the same export result.
Properties
| Property | Explanation | Data Type |
| anchor (Read Only) | Returns one of the following string values that represent the current anchor position. To change the value, use the setAnchor method.
| String |
| camera (Read and Write) | The Camera controls the location and viewing positions of the data being displayed within a map frame. | Camera |

convert_markers | A Boolean that controls the conversion of character-based marker symbols to polygons. This allows the symbols to appear correctly if the symbol font is not available or cannot be embedded. However, setting this parameter to True disables font embedding for all character-based marker symbols, which can result in a change in their appearance. (The default value is False) | Boolean |
EPS files use the PostScript page description language to describe vector and raster objects. PostScript is the publishing industry standard for high-end graphics files, cartography, and printing. EPS files can be edited in many drawing applications or placed as a graphic in most page layout applications. EPS files support embedding of fonts so users who do not have Esri fonts installed can still view the proper symbology.
exportToGIF (out_gif, {resolution}, {world_file}, {gif_color_mode})| Parameter | Explanation | Data Type |

If you export a 3D map frame, this parameter will be ignored regardless of the setting because world files are not applicable to 3D views. (The default value is False) | Boolean |
jpeg_color_mode | This value specifies the number of bits used to describe color.
(The default value is 24-BIT_TRUE_COLOR) | String |
jpeg_quality | This value (0–100) controls the amount of compression applied to the output image. For JPEG, image quality is adversely affected the more compression is applied. A higher quality (highest = 100) setting will produce sharper images and larger file sizes. A lower quality setting will produce more image artifacts and smaller files. (The default value is 80) | Integer |
embed_color_profile | If set to True, color profile information is embedded in the image's metadata. (The default value is True) | Boolean |
JPEG files are compressed image files. They support 24-bit color and are a popular choice for use on the web because a JPEG file size is often substantially smaller than many other image formats. However, the JPEG compression algorithm is lossy and is not recommended for many map images, as line drawings, and text or icon graphics become blurred by compression artifacts. Therefore, PNG is usually a superior format for map images. JPEG files can be generated with an accompanying world file for use as georeferenced raster data.

convert_markers | A Boolean that controls the conversion of character-based marker symbols to polygons. This allows the symbols to appear correctly if the symbol font is not available or cannot be embedded. However, setting this parameter to True disables font embedding for all character-based marker symbols, which can result in a change in their appearance. (The default value is False) | Boolean |
simulate_overprint | Sometimes called soft proofing, simulating overprinting shows a representation of how overlapping areas of ink will appear when printed on a page. You set up overprinting on symbol layers. (The default value is False) | Boolean |
PDF files are designed to be consistently viewable and printable across different platforms. They are commonly used for distributing documents on the web, and the format is now an official ISO standard for document interchange. PDF files are editable in many graphics applications and retain map georeference information, annotation, labeling, and feature attribute data. PDF exports support embedding of fonts and can display symbology correctly even if the user does not have Esri fonts installed.
Review the PDFDocument class to learn more about how to manage PDF files, such as appending, inserting, and setting properties.

(The default value is 32-BIT_WITH_ALPHA) | String |
embed_color_profile | If set to True, color profile information is embedded in the image's metadata. (The default value is True) | Boolean |
PNG is a versatile raster format that can display in web browsers and when inserted into other documents. It supports high-bit-depth color and uses a lossless compression. For maps, PNG is often the best raster format, since the lossless compression keeps text and line work legible by preventing the compression artifacts that can occur in JPEG format. PNG files can also define a transparent color. PNG files can be generated with an accompanying world file for use as georeferenced raster data.

The SVG format is an XML-based file format that is specifically designed for viewing on the web. An SVG file can contain both vector and raster information. Some web browsers may require a plug-in to view SVG files. Older browsers may not be able to view SVG files at all. The SVG format supports the embedding of fonts so users who do not have Esri fonts installed can view SVG exports with proper symbology. You can also produce compressed SVG files. The file extension changes to .svgz when this option is enabled.

(The default value is 80) | Integer |
embed_color_profile | If set to True, color profile information is embedded in the image's metadata. (The default value is True) | Boolean |
TIFF files are the best choice for importing into image editing applications and are also a common GIS raster data format. However, they cannot be natively viewed by a web browser. TIFF files also support georeferencing information in GeoTIFF tags or in a separate world file for use as raster data.
getDefinition (cim_version)
| Parameter | Explanation | Data Type |
cim_version | A string that represents the major version of the CIM that will be used.
| String |
| Data Type | Explanation |
| Object | Returns the CIM definition for a MapFrame value. |
For more information about working with the CIM and samples, see Python CIM access.
getLayerExtent (layer, {selection_only}, {symbolized_extent})| Parameter | Explanation | Data Type |
layer | A reference to a Layer object. | Layer |
selection_only | If True, it returns the extent for selected features; if False, it returns the extent for all features. (The default value is True) | Boolean |
symbolized_extent | A value of True will return the layer's symbolized extent; otherwise, it will return the geometric extent. The symbolized extent takes into account the area the symbology covers so that it does not get cut off by the data frame's boundary. (The default value is True) | Boolean |
| Data Type | Explanation |
| Extent | A geoprocessing Extent object. |
The getLayerExtent method will honor a layer's definition query, so if a subset of features are queried, it will return the extent for only those features. If there are no selected features, the extent for the layer will be returned.
panToExtent (extent)
This method is perfect for situations where the MapFrame scale should not change but the location should. Rather than setting the extent and then having to reset the scale each time, panToExtent maintains the scale and centers the current map frame on the new extent.
setAnchor (anchor)
| Parameter | Explanation | Data Type |
anchor | A string that specifies the location of the anchor position.
| String |
Setting the anchor position is helpful because you can control how the element might expand when resized. For example, the default anchor position for a map frame element is BOTTOM_LEFT_CORNER. If you change the anchor location to TOP_RIGHT_CORNER, changing elementHeight will expand the element downward instead of upward (the default), and changing elementWidth will expand the element to the left.
setDefinition (definition_object)
| Parameter | Explanation | Data Type |
definition_object | A modified CIM definition object originally retrieved using getDefinition. | Object |
For more information about working with the CIM and samples, see Python CIM access.
zoomToAllLayers ({selection_only}, {symbolized_extent})| Parameter | Explanation | Data Type |
selection_only | If True, it sets the extent based on the selected features; if False, it sets the extent for all features in a map. (The default value is True) | Boolean |
symbolized_extent | A value of True will return the layer's symbolized extent; otherwise, it will return the geometric extent. The symbolized extent takes into account the area the symbology covers so that it does not get cut off by the map frame's boundary. (The default value is True) | Boolean |
If zoomToAllLayers is used on a MapFrame with a global or local scene, the result will be a planimetric view.
Code sample
The following script sets the map frame extent in a variety of ways and exports each result to PDF. It first sets the extent using feature selection. Next it zooms to a single layer's extent and applies a slight buffer. Finally, it does the same but zooms to the extent of each feature.
import arcpy, os
aprx = arcpy.mp.ArcGISProject(r'C:\Projects\GreatLakes\GreatLakes.aprx')
m = aprx.listMaps('Map')[0]
lyr = m.listLayers('GreatLakes')[0]
lyt = aprx.listLayouts('Layout')[0]
mf = lyt.listElements('mapframe_element', 'Map Frame')[0]
#Zoom to ALL selected features and export to PDF
arcpy.SelectLayerByAttribute_management(lyr, 'NEW_SELECTION', "NAME = 'Lake Superior'")
mf.zoomToAllLayers(True)
