MapView—ArcGIS Pro | Documentation

Résumé

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 object if a layout 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 only way to change the extent of the Camera associated with a map view.

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.

Attention :

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

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.

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.

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.

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. (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, 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.

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 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.

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

Valeur renvoyée

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)

Paramètre	Explication	Type de données
extent	A geoprocessing Extent object.	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.

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 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)

If zoomToAllLayers is used on a MapView with a global or local scene, the result will be a planimetric view.

zoomToBookmark (bookmark)

Paramètre	Explication	Type de données

If a 3D bookmark is used for a MapView referencing a 2D Map, or the other way around, the result will be a planimetric view.

Exemple de code

Active map view example

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")

MapView web map printing example

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
