PictureElement

摘要

Provides access to properties that enable its repositioning on the page layout as well as getting and setting its data source

讨论

The PictureElement object represents a raster or image that has been inserted into a page layout. In addition to the standard element properties, the PictureElement is unique in that is has a sourceImage property that allows you to read or modify the source location. The ListLayoutElements function returns a Python list of page layout element objects. It is necessary to then iterate through each item in the list or specify an index number to reference a specific page element object. To return a list of only PictureElements, use the PICTURE_ELEMENT constant for the element_type parameter. A wild card can also be used to further refine the search based on the element name.

It is recommended that each page layout element be given a unique name so that it can be easily isolated using arcpy scripting. X and y element positions are based on the element's anchor position, which is set via the Size and Position tab on the Elements Properties dialog box in ArcMap.

代码示例

PictureElement example

The following script will find an image by name and set its data source to a new location.

import arcpy
mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd")
for elm in arcpy.mapping.ListLayoutElements(mxd, "PICTURE_ELEMENT"):
    if elm.name == "Photo1":
        elm.sourceImage = r"C:\Project\Data\Photo.bmp"
mxd.save()
del mxd
