6 entile - create a tiled image pyramid
7
9 entile image1 [path_prefix] [pix_size]
10
12 entile takes an image file name and splits it into a collection of
13 equally sized JPEG tiles representing the image at all resolutions.
14
15 e.g. a 1024x1024 pixel image will be split into the following:
16
17 16 full resolution 256x256 tiles
18
19 4 half resolution 256x256 tiles
20
21 1 quarter resolution 256x256 tile
22
23 The default output prefix path is 't', i.e. output files will be
24 prefixed with 't' in the current working directory.
25
26 The default tile size is 256x256.
27
28 Note that input images are expanded to be square and doubled multiples
29 of the tile size, i.e. for a 256x256 output tile, the input photos are
30 enlarged be one of: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768
31 etc... pixels square
32
33 The naming format is 'keyhole' style, i.e. "q, r, s, t" represent the
34 four quadrants clockwise starting top-left:
35
36 q r
37 t s
38
39 The next level down reproduces the same pattern:
40
41 qq qr rq rr
42 qt qs rt rs
43 tq tr sq sr
44 tt ts st ss
45
46 etc...
