CopyRaster Environment Settings Not Being Applied

PatrickDoody — Fri, 10 Dec 2021 20:46:20 GMT

I am making a call to arcpy.CopyRaster_management to convert some miscellaneous rasters into JPEG2000 *.jp2 files. Before making a call to this line, I want to set a few arcpy.env environment settings to be applied to the copy. Specifically, I would like to specify compression, pyramid, and tilesize.

My code looks like the following:

# Specifying the environment settings
arcpy.env.workspace = outWorkspace
arcpy.env.tileSize = "512 512"
arcpy.env.compression = "JPEG2000 75"
arcpy.env.pyramid = "NONE"
#Copying the raster
arcpy.CopyRaster_management(filepath,name + ".jp2","DEFAULTS","0","0","","ColormapToRGB","8_BIT_UNSIGNED")

The actual raster copies, and is correct. However, my arcpy.env settings are not applied. For example, my tileSize is not set to the specified 512x512, and the *.ovr overviews file is created even though I specified for pyramids to not be created ("NONE").

I am referencing the below document for CopyRaster_management: http://resources.arcgis.com/en/help/main/10.1/index.html#//001700000094000000
At the bottom of the document under "Environments" it lists the environment settings and the tileSize, compression, and pyramid options are listed, so I assume these should be getting applied.

Am I applying these environment settings incorrectly? How can I prevent overviews from being created, and my tileSize from being correctly applied? Any help is appreciated, thanks.

What is your output workspace/storage?

Here is the Raster Storage Matrix to see if those parameters are available for the storage type you are writing to:

Hi Patrick,

The tile size only affects rasters that are stored in TIFFs, file geodatabases, or an SDE geodatabase. See the following link:

http://resources.arcgis.com/en/help/main/10.2/index.html#//001w00000021000000

As for the pyramids not being built, I found the following bug, NIM070791:

The geoprocessing tool, Copy Raster, builds pyramids even if the build pyramids check box in the 'Environment Variable' is unchecked. This happens only when the output is a file raster (TIFF) and when setting any of the parameters like 'Ignore background value', 'colormapToRGB' or 'convert 1 bit data to 8 bit data.'

This appears to occur for JP2 as well as TIFF files. When not specifying the 'Colormap to RGB' option, the OVR file is not created.

I'm having a similar issue. I cannot seem to get the compression environment to work.
I have tried it in a python script with
arcpy.env.compression = "JPG 50"

I get no compression

(original is a tif)

I also tried using ArcTools and change the Raster Storage parameters and get the same thing. No compression.

Did anyone ever figure this out?

Same here -- my script has

arcpy.env.compression = "JPEG2000"

but I end up with LZ77 anyway, which results in a dataset that is too huge. If I can't script this then I have to run it by hand to get the result I need.

Is this still an issue in ArcMap 10.4.1?
