| Jul 5 at 0:08 | comment | added | Vince | The output dimensions determine the image storage requirements -- four tiles nine tile-sizes apart will increase storage 25x (100/4). Choosing to convert 16-bit integer data to 32-bit float seems somewhat arbitrary, and will double the base storage while reducing compressibility (if it even works, which it might not, given the corruption). | |

| Jul 4 at 22:24 | comment | added | Vince | There's a bunch of critical information missing from this Question. How large is the resulting image (rows & cols). How many bits? What compression type? Please Edit the Question. | |
