[Gdal-dev] Re: gdalwarp -wo init_dest issues

[John Mitchell]

Hi,

Regarding the email listed below I was able to figure out issue "a" by
having the RGB value separated by commas (-wo INIT_DEST=226,1,226) which now
displays the  "226 1 226" pixels for areas that don't have any data.
I still can't figure out issue "b".
