Hey all, I borrowed a simple script I found online to clip a shapefile from the extent of a raster. It works perfectly from the ArcMap built in python command prompt. I modified is slightly to use in a tool. It's having issues accepting the raster (inraster) in:
I get the following error:
extent = arcpy.Raster(inRaster).extent
TypeError: expected a raster or layer name
I'm using "Raster Layer" as my inRaster parameter type. The raster type I am using is an ERDAS IMAGINE .img file. I'm thinking it must be conflicting with the parameter type and the .img input raster, but I can't figure out what it is. As I mentioned, it worked from the command prompt, just not in the tool. Any suggestions are welcome.
Code is as follows:
Thanks,
Mike
Code:
extent = arcpy.Raster(inRaster).extentQuote:
extent = arcpy.Raster(inRaster).extent
TypeError: expected a raster or layer name
Code is as follows:
Code:
import arcpy
inLines = arcpy.GetParameter(0)
inRaster = arcpy.GetParameter(1)
outRaster = arcpy.GetParameter(2)
pnt_array = arcpy.Array()
extent = arcpy.Raster(inRaster).extent
pnt_array.add(extent.lowerLeft)
pnt_array.add(extent.lowerRight)
pnt_array.add(extent.upperRight)
pnt_array.add(extent.upperLeft)
poly = arcpy.Polygon(pnt_array)
arcpy.Clip_analysis(inLines, poly, outRaster)Mike
