Description

Hi,

I just compiled up gdal-2.1.3, in the doco (http://www.gdal.org/frmt_mbtiles.html) there is mention of specifying BAND_COUNT, but when I try this:

gdal_translate in.tif out.mbtiles -co 'BAND_COUNT=4' -of MBTILES

I get

Warning 6: driver MBTiles does not support creation option BAND_COUNT

I am trying to make a mbtiles file that has an alpha channel, and it appears that BAND_COUNT isn't supported. gdalinfo says my tif file has four channels, but the resulting out.mbtiles only has RGB. Do you have any clues for me?

Thanks

Matt

It is an opening option. Not a creation option. So it is more "gdalinfo out.mbtiles -oo BAND_COUNT=4" you want to do. The file created should be fine. It is just that guessing the number of channels can be tricky since they may vary from one time to another one depending if the tile is totally opaque or partially.
