Although the TIFF specification allows for higher resolutions for the internal transparency mask, the GeoTIFF driver only supports internal transparency masks of the same dimensions geoiff the main image.
Create a file with less than geotift bits per sample by passing a value from 1 to 7. Paletted images will return palette information associated with the band. GeoTIFF is commonly used for satellite imagery, scanned aerial photography, scanned maps, digital elevation models, or as a result of geographic analyses.
Created files may have any number of bands.
This is particularly useful to save disk space and time when the file must be initialized empty before being passed to a further heotiff stage that will fill it.
You can override default photometric using this option.
