Exporting Data Driven pages as JPEG with World File

Question

I have a script that works to export my pages as jpegs, but I want to add the world file to them. I don't want to have to do all the {df} args and whatnot, I just want to skip to the world file. How can I do this?

Script I currently have:

mxd = arcpy.mapping.MapDocument("CURRENT")
for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):
    mxd.dataDrivenPages.currentPageID = pageNum
    arcpy.mapping.ExportToJPEG(mxd, r"D:\Matt_work\jpgs" + str(pageNum) + ".jpg")
del mxd

EDIT: If I use this script:

mxd = arcpy.mapping.MapDocument("CURRENT") 
for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):
    mxd.dataDrivenPages.currentPageID = pageNum
    arcpy.mapping.ExportToJPEG(mxd, r"D:\Matt_work" + str(pageNum) + ".jpg", world_file=True)
del mxd

I get this runtime error:

Runtime error

When exporting a Page Layout to JPG you cannot generate a world file with it - this is the same when using the Export dialog from within ArcMap (File > Export Map).

World files are not generated for page layout exports; a referenced data frame must be provided or the export will fail.

(from ExportToJPEG)

This is because a Page Layout can include a lot of other information including multiple data frames, so there is no way to determine which georeference information to export with the image.

You can export to JPG from the Data View and include the world file information, even from Data Driven Pages. To do this you do need to specify the data frame you want to export.

import arcpy

mxd = arcpy.mapping.MapDocument("CURRENT") 
df = arcpy.mapping.ListDataFrames(mxd)[0]

for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):
    mxd.dataDrivenPages.currentPageID = pageNum
    arcpy.mapping.ExportToJPEG(mxd, r"N:\GISSE\DDP\Export{}.jpg".format(pageNum), df, world_file=True)
del mxd

You may also like to include the Export width df_export_width and Export Height df_export_height as the default size for exported data frame images is rather small at 640x480 pixels.

arcpy.mapping.ExportToJPEG(mxd, r"N:\GISSE\DDP\Export{}.jpg".format(pageNum), df, df_export_width=1600, df_export_height=1200, world_file=True)
