Generating Deep Zoom images with VIPS

[Benjamin Gilbert]

Hi all,

VIPS 7.30.1 adds a Deep Zoom generator that works with arbitrary 
VIPS-loadable images, including slide files supported by OpenSlide.  To 
produce a Deep Zoom tree compatible with the one produced by 
deepzoom_tile.py:

     vips dzsave CMU-1.svs CMU-1

VIPS produces Deep Zoom trees by repeated downsampling, so it should run 
faster and produce higher-quality output than deepzoom_tile.py.  If 
you're creating statically-tiled Deep Zoom trees from whole-slide 
images, I recommend giving it a look!
