Summary
The MapView class is intended to be used in two workflows. Firstly, it can be used in an ArcGIS Pro project to access the currently active map view. Secondly, it can be used in conjunction with ConvertWebMapToArcGISProject in a web map printing application to access a map view to print or export.
Discussion
The MapView class can be used to gain access to the active map view in an ArcGIS Pro project. The activeView property from the ArcGISProject class will either return a MapView object if a map view is active or it will return a Layout or Report object if a layout view or report view is active. Any other type of view will return None. The activeView property is intended for scripts that are to be executed in the ArcGIS Pro application, such as scripts run in the Python pane or those associated with a script tool.
The MapView returned from the activeView property is the primary way to change the extent of the Camera associated with the view. You can also change the defaultCamera property on the Map object before calling the openView method and the newly opened view will honor those camera settings. The ArcGISProject class has a closeViews method that is useful for closing unnecessary views before opening a view giving it more focus.
The MapView class can also be used in web map printing workflows. The MapView class provides access to a map view to print or export a web map that doesn't contain page layout surroundings (for example, title, legends, and scale bar). This is generally used by web app developers who are creating web map printing applications. For more information, see ConvertWebMapToArcGISProject.
Caution:
Not all MapView methods are available to web app developers. The following methods are not supported in a web map printing application:
- getLayerExtent
- panToExtent
- zoomToAllLayers
- zoomToBookmark

jpeg_compression_quality | A number that controls compression quality value when image_compression is set to ADAPTIVE or JPEG. The valid range is 1 through 100. A jpeg_compression_quality of 100 provides the best quality images but creates large export files. The recommended range is between 70 and 90. (The default value is 80) | Integer |
embed_fonts | A Boolean that controls the embedding of fonts in the export file. Font embedding allows text and character markers to be displayed correctly when the document is viewed on a computer that does not have the necessary fonts installed. (The default value is True) | Boolean |
embed_color_profile | If set to True, color profile information is embedded in the image's metadata. (The default value is True) | Boolean |
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 |
AIX is an Adobe Illustrator Exchange file exported from ArcGIS to be used with the ArcGIS Maps for Adobe Creative Cloud plug-in. When used with the plug-in, vector and raster map content is converted into editable, layered artwork for an improved editing experience in Adobe Illustrator. Once opened in Illustrator, it can be used for high-end graphic design or map finishing workflows and migrated across the other Adobe Creative Cloud applications.

output_as_image | If set to True, vector content can be saved as an image. 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. (The default value is False) | Boolean |
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 |
EMF files are native Windows graphics files that can contain a combination of vector and raster data. They are useful for embedding in Windows documents because the vector portions of the EMF file can be resized without loss of quality. However, since an EMF file does not support font embedding and is exclusively a Windows format, it is not commonly used as an interchange format between users.
exportToEPS (out_eps, width, height, {resolution}, {image_compression}, {image_quality}, {embed_fonts}, {output_as_image}, {convert_markers})| Parameter | Explanation | Data Type |

output_as_image | If set to True, vector content can be saved as an image. 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. (The default value is False) | Boolean |
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.

height | A number that defines the height of the export in pixels. | Integer |
resolution | A number that defines the resolution of the export file in dots per inch (dpi). (The default value is 96) | Integer |
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. (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, the PNG format is usually superior for map images. JPEG files can be generated with an accompanying world file for use as georeferenced raster data.
exportToPDF (out_pdf, width, height, {resolution}, {image_quality}, {compress_vector_graphics}, {image_compression}, {embed_fonts}, {layers_attributes}, {georef_info}, {jpeg_compression_quality}, {output_as_image}, {embed_color_profile}, {convert_markers}, {simulate_overprint})| Parameter | Explanation | Data Type |

(The default value is LAYERS_ONLY) | String |
georef_info | A Boolean that enables the export of coordinate system information for each data frame into the output PDF file. (The default value is True) | Boolean |
jpeg_compression_quality | A number that controls the compression quality value when image_compression is set to ADAPTIVE or JPEG. The valid range is 1 through 100. A jpeg_compression_quality of 100 provides the best quality images but creates large export files. The recommended range is 70 through 90. (The default value is 80) | Integer |
output_as_image | If set to True, vector content can be saved as an image. 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. (The default value is False) | Boolean |
embed_color_profile | If set to True, color profile information is embedded in the image's metadata. (The default value is True) | Boolean |
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 |
The PNG format is a versatile raster format that can display in web browsers and be 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. (The default value is False) | Boolean |
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 |
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.

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. (The default value is False) | Boolean |
color_mode | This value specifies the number of bits used to describe color. The available options are dependent on the specified Color Model set in the layout's Color Management properties.
(The default value is 24-BIT_TRUE_COLOR) | String |
tiff_compression | This value represents a compression scheme.
(The default value is LZW) | String |
geoTIFF_tags | If set to True, georeferencing tags are included in the structure of the TIFF export file. The tags contain pixel scale information and real-world coordinate information. These tags can be read by applications that support the GeoTIFF format. (The default value is False) | Boolean |
jpeg_compression_quality | This value (0–100) controls the amount of compression applied to the output image. With a JPEG image, quality is adversely affected the more compression is applied.

(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.
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 in which the 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 camera on the new extent.
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 MapView with a global or local scene, the result will be a planimetric view.
Code sample
In this example, the MapView extent is modified for the currently active map view before being exported to a PNG file. The ArcGIS Pro project is referenced using the current keyword. This script is intended to be run in the Python pane or a script tool.
import arcpy, os
aprx = arcpy.mp.ArcGISProject('current')
mv = aprx.activeView
# Change the extent of the map view
ext = mv.camera.getExtent()
ext.XMin = ext.XMin + 100
ext.YMin = ext.YMin + 100
ext.XMax = ext.XMax - 100
ext.YMax = ext.YMax - 100
mv.camera.setExtent(ext)
# Export the map view
Output_File = os.path.join(arcpy.env.scratchFolder, 'ActiveMapView.png')
mv.exportToPNG(Output_File, width=1000, height=1000, world_file=True, color_mode="32-BIT_WITH_ALPHA")In this example, the script reads in a web map JSON. The output MapView from ConvertWebMapToArcGISProject is exported to a PNG file.
import arcpy
import os
import uuid
# Input web map json
Web_Map_as_JSON = arcpy.GetParameterAsText(0)
# Convert the web map to an ArcGIS Project
result = arcpy.mp.ConvertWebMapToArcGISProject(Web_Map_as_JSON)
aprx = result.ArcGISProject
# Get the map view
m = aprx.listMaps()[0]
mv = m.defaultView
# Use the uuid module to generate a GUID as part of the output name
# This will ensure a unique output name
output = 'WebMap_{}.png'.format(str(uuid.uuid1()))
Output_File = os.path.join(arcpy.env.scratchFolder, output)
# Export the web map
mv.exportToPNG(Output_File, result.outputSizeWidth, result.outputSizeHeight, result.DPI)
# Set the output parameter to be the output file of the server job
arcpy.SetParameterAsText(1, Output_File)
# Clean up
del mv, m, aprx, resultThe following script uses the keyword current, so it should be run from the Python window. The script creates a new map and adds new layers to it. The map's default camera property is updated, which controls the extent of newly opened views. The map view is then exported to PDF. The newly created map is then removed from the project.
aprx = arcpy.mp.ArcGISProject("CURRENT")
#Create a copy of an existing map
newMap = aprx.createMap("Ranger Stations", "Map")
#Add ranger stations layer file
