Résumé
The MapFrame object is a page layout element that is used to display the contents of a map on a layout. It also provides access to page size and positioning, basic navigation methods, and export options.
Discussion
A MapFrame is a Layout element that displays the geographic information added to a Map. It also controls the size and positioning of itself on a layout. More than one MapFrame can reference the same Map.
The listElements function on the Layout object can be used to return MapFrame objects. Providing an element_type of MAPFRAME_ELEMENT allows you to return only MapFrame elements. You can also further refine your filter by providing a wildcard. It is important to uniquely name each map frame so it can be easily referenced using its name property.
Once a MapFrame is referenced, you can get its associated map using the map property, which would allow you to manage layers on a map, get to a map's bookmarks, and more. Even more important is that you can change the Map object a MapFrame is referencing. You can switch maps of the same dimension or different dimensions. If you change the dimension of a map, you must first change the type property on the MapViewer object. For example, if the Camera mode is MAP (for 2D), you must change the mode to LOCAL or GLOBAL (for 3D). Once this is done, you can change the map from 2D to 3D.
The camera property returns a reference to the Camera object. The Camera controls the location and viewing positions of the data being displayed within a map frame. It controls items like scale and extent for 2D maps and camera position information for 3D maps.
It is important to understand the navigation methods and how they work between map (2D) and scene (3D) map frames. Anytime a 2D map, bookmark, or method that uses an extent is applied to a 3D map frame, the result will be a planimetric view of the data. The getLayerExtent, panToExtent, and zoomToAllLayers will always result in a planimetric view. The zoomToBookmark method maintains a 3D view when working between 3D map frames, but once a 2D bookmark is used on a 3D map frame or the other way around, the result will be a planimetric view of the map frame's data.
The elementPositionX and elementPositionY parameters are based on the element's anchor position.

world_file | If set to True, a georeferenced world file is created. The file contains pixel scale information and real-world coordinate information. 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. (La valeur par défaut est False) | Boolean |
jpeg_color_mode | This value specifies the number of bits used to describe color.
(La valeur par défaut est 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.

(La valeur par défaut est 80) | Integer |
embed_color_profile | If set to True, color profile information is embedded in the image's metadata. (La valeur par défaut est 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.

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.

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.

Selecting this option for maps or layouts that contain vector layers with a high density of vertices can reduce the output file size. When exporting to PDF and this option is set to True, you cannot view PDF layers in the output. (La valeur par défaut est False) | Boolean |
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.

getLayerExtent (layer, {selection_only}, {symbolized_extent})| Paramètre | Explication | Type de données |
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. (La valeur par défaut est 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. (La valeur par défaut est True) | Boolean |
| Type de données | Explication |
| 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.
zoomToAllLayers ({selection_only}, {symbolized_extent})| Paramètre | Explication | Type de données |
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. (La valeur par défaut est 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. (La valeur par défaut est True) | Boolean |
If zoomToAllLayers is used on a MapFrame with a global or local scene, the result will be a planimetric view.
Exemple de code
The following script will set the extent of a map frame named Yosemite National Park on a layout named Main Attractions at Yosemite National Park to match the extent of a layer named Ranger Stations.
import arcpy
aprx = arcpy.mp.ArcGISProject(r"C:\Projects\YosemiteNP\Yosemite.aprx")
