[Gdal-dev] gdalwarp -srcnodata Question

List,

If I specify

-scrnodata 0 in gdalwarp will it perform transparency on RGB when the pixel 
values on all 3 bands are equal to 0 (R=0, G=0, B=0), or whenever it finds 
a pixel value of 0 on any of the bands performing transparency on those 
bands? or

do I need to specify

-scrnodata "0 0 0" in order to get transparency only when the pixel values 
of all 3 bands are equal to 0  (R=0, G=0, B=0)?

Thanks in advance for the help.

Reinaldo
