deepzoom_tile.py slowness

[Mathieu Malaterre]

Hi all,

  I am trying to use deepzoom_tile.py on some TIFF files [1]. The
application has been running for quite some time (>1 hour) without
producing any output so far. Does anyone know what type of preprocess
I should run on those TIFF files to make them more efficient with
openslide ?

Thanks
