WMS provider doesn't support GrayIndex with Alpha band

Reported by: christinebao Owned by: christinebao
Priority: major Milestone: 3.5.0
Component: WMS Provider Version: 3.4.0
Severity: 3 Keywords:
Cc: External ID: 1204197.01

Description

Steps to reproduce:

  1. connect to WMS server: ​http://wms.jpl.nasa.gov/wms.cgi?
  2. try to read the feature class "Digital Elecation Map of the United States,DTED dataset, 3 second resolution,grayscale"'s raster property GetNumberOfBands().

Result: Exception thrown out.

How to fix: this raster contains 2 bands: first is GrayIndex and second is Alpha. WMS can't recognize this kind of combination and caused the exception. As WMS only support 4 bands of Red, Green, Blue, Alpha, the way to fix is to expand GrayIndex to Red, Green and Blue, and then WMS provider can deal with it.
