Hi all,

I'm trying to write a foreach loop to convert all bands in an existing ENVI Raster into output PNGs. When I run the following loop:

"foreach i, bandGet do begin
Subset = ENVISubsetRaster(raster, bands=[i])

print, (baseName + bNames[i])

; Creating the PNG routine from ENVI Docs

Task = ENVITask('ExportRasterToPNG')

Task.INPUT_RASTER = Subset

Task.OUTPUT_RASTER_URI = (baseName + bNames[i])

Task.Execute

Task.output_raster = outName
end"

I get the exact filenames I want printed, but no files are written. I also get a message saying "This task has no parameter named OUTPUT_RASTER_URI" - is that a feature introduced in a newer version of ENVI?

Any pointers to get this working in ENVI 5/2/IDL 8.4 would be greatly appreciated!
