Summary
The Layout object references a single-page layout in an ArcGIS Pro project (.aprx). It provides access to common properties like page size and a number of different 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 specific page layout can be easily referenced by its name.
The listElements method provides access to all the elements on the page layout: GraphicElement, LegendElement, MapFrameElement, MapSurroundElement, PictureElement, and TextElement.
The Layout object is where you'll find access to a number of 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 available 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, then a map series has not been created in the layout. You should also check to see if the map series is enabled before attempting to manipulate its properties.
Properties

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.

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.

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 version 2.4. Esri follows the semantic versioning specification. This means that until the next major release—for example, 3.0—when breaking API changes are allowed, the value to be used with cim_version is V2. Once 3.0 is released, a new V3 option will become available. This gives Python script authors control over the CIM version that will be used during execution if there is a possibility that breaking changes may be introduced in the new version.
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]
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.
Code sample
The following script uses the keyword current, so it should be run from the Python window. The script prints the name of each map in a project and its layers as well as the name of each layout and its page size.
