I am using data driven pages and want to automatically export my layouts/extents to PNG. Since you have to use arcpy to export to PNG with data driven pages, I used following code, as explained here: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00sm00000008000000
mxd = arcpy.mapping.MapDocument("CURRENT") for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1): mxd.dataDrivenPages.currentPageID = pageNum arcpy.mapping.ExportToPNG(mxd, r"C:\Temp\ParcelAtlas_Page" +str(pageNum) + ".png") del mxd
The problem is that the quality is very bad when I export like this. If I export to PNG manually, and set for example 300 dpi, it is way better than exporting automatically.
Would you know a solution to export in better quality using arcpy and data driven pages in ArcMap?
