[gdal-dev] How to decrease file size of colored raster bands?

[afernandez]

Hi Scott and Laurentiu,
It is now compressing the file. On a minor note I usually prefer to use 'subprocess' instead of 'os.system' but either way it is now a matter of experimenting with the flags and finding out which is the best combination to compress the project output files. 
Thanks for all your help,
Arturo

Hi,
Try saving the output into a new file. Those are "creation options".

Hello Laurentiu,
The color palette is working fine. The issues seem to be caused by using UInt16 because I changed to GDT_Byte per your suggestion and everything is so much smoother (this was an oversight of mine as I recycled a snippet from somewhere and should have paid much closer attention to this detail). 
As for compressing and using overviews (for future use), I'm having some difficulty implementing them but it's less urgent and will keep working at it.
Thanks,
Arturo
