Hi all I am running "gdal2tiles" over input GeoTIFF from the command line. Some times those geotiff may have an alpha band (usually and RGBA uint8 image), or nodata value (usually a float32 image), or sometimes none of them. In the last case I will add the option "-a 0,0,0" or "-a 0" (yes, black is the new transparent), but on the other two cases I shouldn't add that option.
Is there any efficient way via the command line to detect if a file has some kind of transparency mask, apart for parsing the output of gdalinfo? Thanks .___ ._ ..._ .. . ._. .___ .. __ . _. . __.. ... .... ._ .__ Entre dos pensamientos racionales hay infinitos pensamientos irracionales.
