[Edited to include example image outputs]
SE folks, I'm wanting to modify
generate_tiles.py to create 512 x 512 tiles.
At om_henners' recommendation, I tried replacing 12 of the 13 instances of
256 in the Python file (the 13th specifies the
.PNG image format). I've since tried a test run, and I can already tell something is wacky...
Replacing all the relevant 256's with 512's merely produces a larger tile, when the intended result is increased mapped-area per tile (I think it amounts to 4x coverage).
Posting the code isn't worthwhile becuase you can see it here, but it is worth noting this is the only line for which I did not change 256 to 512 between test runs:
im.save(tile_uri, 'png256') <-- the only 256 not changed to 512
So I'm getting these two outputs, and I have two curious observations:
1) The file address is the same. I would expect---if the mapped-area was changed between runs---the same location should fall into a different file, no?
2) Even though the mapped-area remained the same, the 512 tiles gained labels. Very interesting.
Thanks in advance for the help!
