DESCRIPTION

33       This program is part of Netpbm(1).
34
35       pnmindex  creates  an index image containing thumbnail (small) versions
36       of a bunch of PNM files you supply.  (Akin to a  photographic  'contact
37       sheet.'
38
39       pnmindex labels each thumbnail and, optionally, contains a title.
40
41       If  you  just  want  to concatenate some images together in a grid, use
42       pamundice for that.
43
44       If you want to take apart the image you generated  with  pnmindex,  use
45       pamdice or pamcut.

OPTIONS

49       -size=N
50              The  size  of  each thumbnail.  The image is scaled to fit maxi‐
51              mally inside a N x N  pixel  box  without  changing  its  aspect
52              ratio.  Default is 100.
53
54
55       -across=N
56              The number of thumbnails in each row.  Default is 6.
57
58
59       -colors=N
60              The  maximum  number of colors allowed in the overall image.  If
61              it would otherwise have more colors than these,  pnmindex  quan‐
62              tizes the result.  The default is 256.
63
64              However,  this  value is meaningless if you specify the -noquant
65              option.
66
67
68       -black This controls the color of the padding between the images;  nor‐
69              mally  it's  white  and  the labels are black lettering on white
70              background, but the -black option reverses this.
71
72
73       -title=title
74              Specifies a title top place at the top of the image.  Default is
75              no title.
76
77
78       -quant Enables  quanization (to the number of colors specified by -col‐
79              ors).  Quantization is on by default but you can disable it with
80              -noquant.
81
82
83       -noquant
84              See -quant.
