Good morning all
I'm trying to pull together some code to export the data view (not the page layout view) to PNG. The issue I'm having is that when I use the df variable in the ExportToPNG function, I am getting an Assertion Error. If I substitute df for "PAGE_LAYOUT" the script runs, but the output is not what I'm looking for.
Any ideas how to solve this?
This is what I've got so far:
Edit: I didn't actually get this above code to run, but I got similar code running thru the Python window in ArcMap.

This is what I've got so far:
Code:
import arcpy
import os
from arcpy import env
from time import localtime, strftime
# Set workspace
arcpy.env.workspace = r'd:\gis\aerialtracking\output'
ws = arcpy.env.workspace
if str(os.path.exists(ws)) == "False":
os.makedirs(ws)
# Set time variable and print output variable
printtime = strftime("%Y%m%d_%H%M", localtime())
print printtime
pngname = "mapexport_" + printtime + ".png"
print pngname
# Set mxd
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd)
#Export PNG
arcpy.mapping.ExportToPNG(mxd, pngname, df, df_export_width = 1600, df_export_height = 1200, world_file = True)
#delete variables
del df, ws, printtime, pngname, mxdCode:
>>> arcpy.mapping.ExportToPNG(mxd, r'D:\gis\aerialtracking\output\test.png', "PAGE_LAYOUT")
>>> arcpy.mapping.ExportToPNG(mxd, r'D:\gis\aerialtracking\output\test.png', df)
