#4124 closed enhancement (fixed)

allow nearblack mask on single band images

Reported by: maphew Owned by: warmerdam
Priority: normal Milestone: 1.9.0
Component: Utilities Version: 1.8.0
Severity: normal Keywords: nearblack


When nearblack is used on a single band image with -setmask it stops with an error:

nearblack  -setmask -of gtiff -o decollared.tif gray.tif
ERROR 1: Number of bands of file = 1. Expected 3 or 4.

Without setmask it works fine. It would be nice to be able to use masks on grayscale images without incurring the overhead of converting to RGB.
