# slicerdicer
|
|
|
|
Slice and dice an image, turning it into many equal sized tiles. Useful
|
|
for things like leaflet.js, with the Leaflet.Zoomify plugin.
|
|
|
|
The image is sliced up into equal sized tiles, based on the command line
|
|
option `--tile-size` (default 512 pixels).
|
|
|
|
Once the tiling is finished, the original is resized to half its current
|
|
dimensions (the orignal file on disk is not touched) and the process repeats.
|
|
Each halving is a new "zoom level".
|
|
|
|
Each file is named something like:
|
|
|
|
tile-z-x-y.png
|
|
|
|
Where 'z' is the zoom level, x and y are the coordinates, with 0,0 being
|
|
the top left tile.
|
|
|
|
## Usage
|
|
|
|
slicerdicer --help
|
|
|
|
slicerdicer --filename foo.png --tile-size 256 --concurrency 5
|
|
|
|
## Notes
|
|
|
|
It's going to eat some memory.
|
|
|
|
In my tests on an 32641 x 16471, 8-bit/color RGB PNG, memory usage peaks at
|
|
around 2.7GB.
