VIPS

2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536

Get size info

vipsheader -a input.svg

Resize to a power of 2

vipsthumbnail input.png --size 16384x -o output.png --vips-progress

Make PNGtiles

VIPS will extend your input to get a “power of 2” size.

If you want to maximize your zoom wihle scaling and keeping the same coordinates with Overlay, make sure your inital input size is of a power of 2 minus 1 (not sure about that)

vips dzsave 'kn.svg[scale=15]'  tiledir --layout google --centre --suffix .png --vips-progress
vips dzsave 'suttapitaka.svg[scale=8]'  maptilesHD --layout google --centre --suffix .png --tile-size 1024 --vips-progress

Extend with white

vips gravity input.png south-west 8192 8192 --extend white --vips-progress
vips gravity input.png centre 8192 8192 --extend white --vips-progress

Copy

vips copy 'input.svg[dpi=10, scale=10]' output.png --vips-progress	
vips copy 'dark.svg[scale=5]' dark.png --vips-progress

TIFF Tiles

Calcul scale

2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536

size = width > height ? width : height
factor = 32768 / size

width=$(vipsheader -f width somefile.tif)
height=$(vipsheader -f height somefile.tif)
size=$((width > height ? width : height))
factor=$(bc <<< "scale=10; 32768 / $size")
vips resize somefile.tif huge.tif $factor
