Summary
The Layout object references a single-page layout in an ArcGIS Pro project (.aprx). It provides access to common properties such as page size and various export methods.
Discussion
An ArcGIS Pro project can contain multiple page layouts. Layouts are accessed using the listLayouts method on the ArcGISProject object and it returns a Python list of Layout objects. It is important to uniquely name each layout so a layout can be easily referenced by its name.
The listElements method provides access to all the elements on the page layout: GraphicElement, GroupElement, LegendElement, MapFrameElement, MapSurroundElement, PictureElement, and TextElement.
The Layout object is where you'll find access to various exportTo methods. Use the Layout export methods if you want to export the entire page layout. There is also a similar set of export methods on the MapFrame class, if you only want to export the contents of a single map frame.
A layout can contain a single MapSeries. If the mapSeries property returns None, a map series has not been created in the layout. You should also check to see whether the map series is enabled before attempting to manipulate its properties.
The createLayout method on the ArcGISProject object allows you to completely automate the creation of a layout. Once a layout exists, there are many additional creator methods for creating the different types of layout elements. The layout object has two create methods for creating elements that can only exist on a layout. They are createMapFrame and createMapSurroundElement. The ArcGISProject object includes more create methods that allow you to create elements in a layout or in a graphics layer in a map. Those methods are createGraphicElement, createGroupElement, createPictureElement, createPredefinedGraphicElement, and createTextElement.
The openView method allows you to open a new view pane of your layout. There are currently no ways to determine whether a view is already open or whether your layout view is active because views can't be queried. What you can do is use the closeViews method on the ArcGISProject object and call openView on your layout. This will open and activate your layout so that it has the area and focus you might want.
Note:
The openView and closeViews methods only work for scripts run from within the application. Stand-alone scripts can't access view panes.

keep_layout_background | If set to True, the layout's white background will be kept. (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 |
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.

jpeg_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. 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 |
clip_to_elements | If set to True, the layout is clipped to the smallest bounding box that includes all layout elements. (The default value is False) | 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.

A PNG file is a versatile raster format file 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.

SVG is an XML-based file format that has been specifically designed for viewing on the web. SVG 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. SVG supports font embedding, so users who do not have Esri fonts installed can still view SVG exports with proper symbology. You can also choose to produce compressed SVG files. The file extension changes to .svgz when this option is enabled.

(The default value is 80) | Integer |
transparent_background | If set to True, the white page background is set to transparent. (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 |
clip_to_elements | If set to True, the layout is clipped to the smallest bounding box that includes all layout elements. (The default value is False) | Boolean |
world_file | 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 |
geoTIFF_tags | If set to True and a valid georef_mapframe is set, geoTIFF tags will be embedded in the resulting image based on the map frame's coordinate system. (The default value is False) | Boolean |
georef_mapframe | The MapFrame used to control the coordinate system when geoTIFF_tags are set to True. (The default value is None) | MapFrame |
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.
getDefinition (cim_version)
| Parameter | Explanation | Data Type |
cim_version | A string that represents the major version of the CIM. | String |
CIM-level access to additional object properties was introduced at ArcGIS Pro 2.4. When you want to return an object's CIM definition, you must specify a cim_version. Esri follows the semantic versioning specification. This means that at major releases—for example, 3.0—breaking API changes are allowed. This allows Python script authors control over which version of the CIM is used during a script run if there is a possibility breaking changes may be introduced in the new version. If you are authoring scripts for ArcGIS Pro 2.x, specify the cim_version to be 'V2'. If you are authoring scripts for ArcGIS Pro 3.x, specify the cim_version to be 'V3'. Scripts authored using cim_version 'V2' will continue to work in ArcGIS Pro 3.x.
For more information about working with the CIM and samples, see Python CIM access.
listElements ({element_type}, {wildcard})| Parameter | Explanation | Data Type |
element_type | A string that represents the element type that will be used to filter the returned list of elements.
(The default value is None) | String |
wildcard | A wildcard is based on the element name and is not case sensitive. A combination of asterisks (*) and characters can be used to help limit the results. (The default value is None) | String |
| Data Type | Explanation |
| List | A Python list of page layout elements. The types of objects that can be returned are GraphicElement, LegendElement, MapFrame, MapsurroundElement, PictureElement, and TextElement. |
Each page element has a name property that can be set within the element properties dialog box. It is the layout author's responsibility to ensure each page element is given a unique name so that elements can be uniquely identified. If two elements have the same name, there is no way to ensure it is the element you want to reference.
The listElements method will return the elements within a group element into a flattened list. This makes it possible to easily search and replace text strings, for example, without having to navigate through a group element structure.
The element_type parameter can be skipped by passing an empty string or by including the parameter name for all parameters that follow the skipped parameter. For example
elm = lyt.listElements("", "Title")[0]
#or
elm = lyt.listElements(wildcard="Title")[0]
openView ()
This is useful if the layout view is not already open or another view is active in the application. The method creates a layout view zoomed to its full extent and activates it. To close other, existing views before opening a new view, use the ArcGISProject closeViews method.
Note:
This method is designed to be run in the application using a script tool, Notebook, or the Python window. It will have no effect if run outside of the application.
setDefinition (definition_object)
| Parameter | Explanation | Data Type |
definition_object | A modified CIM definition object originally retrieved using getDefinition. | Object |

Code sample
The following script iterates through all layouts in the current project and prints basic information about each layout including name, page size and units, number of map frames, map frame names, and the total number of layout elements.
aprx = arcpy.mp.ArcGISProject('CURRENT')
print(f'Total Project Layout Count: {str(len(aprx.listLayouts()))} \n')
for lyt in aprx.listLayouts():
print(f'Layout Name: {lyt.name}')
print(f' Width x height: {lyt.pageWidth} x {lyt.pageHeight} units are {lyt.pageUnits}')
print(f' MapFrame count: {str(len(lyt.listElements("MapFrame_Element")))}')
for mf in lyt.listElements("MapFrame_Element"):
if len(lyt.listElements("MapFrame_Element")) > 0:
print(f' MapFrame name: {mf.name}')
print(f' Total element count: {str(len(lyt.listElements()))} \n')The following script iterates through a list of layout names and exports each layout to PDF two times. The first export uses the default settings for exportToPDF. The second export produces a much smaller output file because the resolution, image_quality, and output_as_image parameters are set accordingly.
import arcpy, os
prjPath = r'C:\Projects\YosemiteNP'
p = arcpy.mp.ArcGISProject(os.path.join(prjPath, 'Yosemite.aprx'))
layoutNames = ['Main Attractions', 'Scenic Views']
for name in layoutNames:
lyt = p.listLayouts(name)[0]
#export to PDF - default settings
lyt.exportToPDF(os.path.join(prjPath, 'Output', name + '_defaults.pdf'))
#export to PDF - smaller file size
lyt.exportToPDF(os.path.join(prjPath, 'Output', name + '_small.pdf'), 100,
image_quality = 3,
output_as_image = True)The following script creates a map and layout. It also creates a map frame, north arrow, and scale bar in the layout. A rectangle helper function is included for making the geometries needed for the map frame and scale bar. Finally, it ensures that the new layout is opened and activated in the application.
def MakeRec_LL(llx, lly, w, h):
xyRecList = [[llx, lly], [llx, lly+h], [llx+w,lly+h], [llx+w,lly], [llx,lly]]
array = arcpy.Array([arcpy.Point(*coords) for coords in xyRecList])
rec = arcpy.Polygon(array)
return rec
p = arcpy.mp.ArcGISProject('current')
#Create a new map and layout
m = p.createMap('New Map', 'MAP')
lyt = p.createLayout(8.5, 11, 'INCH')
#Create a map frame
mf = lyt.createMapFrame(MakeRec_LL(0.5,5.5,7.5,5), m, "New Map Frame")
#Create a north arrow
naStyle = p.listStyleItems('ArcGIS 2D', 'North_Arrow', 'Compass North 1')[0]
na = lyt.createMapSurroundElement(arcpy.Point(7,7), 'North_Arrow', mf,
naStyle, "Compass North Arrow")
na.elementWidth = 0.5
#Create a scale bar
sbName = 'Double Alternating Scale Bar 1 Metric'
sbStyle = p.listStyleItems('ArcGIS 2D', 'Scale_bar', sbName)[0]
sbEnv = MakeRec_LL(0.5, 5.5, 2.5, 0.5)
sb = lyt.createMapSurroundElement(sbEnv, 'Scale_bar', mf, sbStyle, 'New Scale Bar')
#Close all view and open and active the layout view
p.closeViews()
lyt.openView()The following script shows different ways to use deleteElement. Note that to remove group elements that may exist inside of other group elements, you must delete group elements in opposite order because you must delete the child elements before the parent.
p = arcpy.mp.ArcGISProject('current')
lyt = p.listLayouts('Layout')[0]
#Delete one element by name
elm = lyt.listElement('GRAPHIC_ELEMENT', 'Point')[0]
lyt.deleteElement(elm)
#Delete all the group elements and their children in reverse order
for elm in reversed(lyt.listElements('GROUP_ELEMENT')):
lyt.deleteElement(elm)
#Delete remaining elements
for elm in lyt.listElements():
lyt.deleteElement(elm)The following script demonstrates how to use Python CIM Access to add guides to a layout. It creates four new guides 0.5 inches from the edges of the layout.
#CAUTION - this script will remove any existing guides
p = arcpy.mp.ArcGISProject('CURRENT')
for lyt in p.listLayouts():
lyt_cim = lyt.getDefinition('V3')
newGuides = []
#Bottom horizontal guide
botHorz = arcpy.cim.CreateCIMObjectFromClassName('CIMGuide', 'V3')
botHorz.position = 0.5
botHorz.orientation = 'Horizontal'
newGuides.append(botHorz)
#Top horizontal guide
topHorz = arcpy.cim.CreateCIMObjectFromClassName('CIMGuide', 'V3')
topHorz.position = lyt.pageHeight - 0.5
topHorz.orientation = 'Horizontal'
newGuides.append(topHorz)
#Left vertical guide
leftVert = arcpy.cim.CreateCIMObjectFromClassName('CIMGuide', 'V3')
leftVert.position = 0.5
leftVert.orientation = 'Vertical'
newGuides.append(leftVert)
#Right vertical guide
rightVert = arcpy.cim.CreateCIMObjectFromClassName('CIMGuide', 'V3')
rightVert.position = lyt.pageWidth - 0.5
rightVert.orientation = 'Vertical'
newGuides.append(rightVert)
#Add guides and make sure they are turned on
lyt_cim.page.guides = newGuides
lyt_cim.page.showGuides = True
#Set back to layer
lyt.setDefinition(lyt_cim)
