Exporting Layers to PNG using Python

AqeelAhmed — Fri, 11 Apr 2014 08:13:45 GMT

Hi guys!

I'm pretty new to python and have a question about an automation i'm trying to achieve. Is it possible to export several layers to a specific file format (the module offers several) using python. For instance if i have two layers in my data frame (a point feature and a line feature) and i want to export these to PNG separately, I would normally turn off one layer and export the other. Then i would repeat the process again for the remaining layer. Hypothetically if I had 20 layers which I wanted to export this way it would be useful if I had the process automated. Is it possible to write a script that does this? I acknowledge the fact this might be comprehensive, but if it is possible then any "kickstarters" of code in the right direction would be appreciated.
Thank you:)

Use export to png:

You will also need to set the extent inside the loop (you will need to save and close the mxd with all layers turned off):
I have not tested this so you might have to tinker with it.

  mxd = arcpy.mapping.MapDocument(r"C:\Maps\MakeMaps.mxd") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] #df name is "Layers" in this example for lyr in arcpy.mapping.ListLayers(mxd):     lyr.visible = True       ext = lyr.getExtent()     df.extent = ext     arcpy.mapping.ExportToPNG(mxd, r"C:\Maps\Exports\"  + lyr + ".png")

Thanks! I'll give it a run 🙂
