NAME

6       unipng2hex  -  Portable  Network Graphics to GNU Unifont .hex file con‐
7       verter
8

SYNOPSIS

10       unipng2hex -i input_file.png [-o output_file.hex ] [-w width ]
11

DESCRIPTION

13       unipng2hex reads a PNG file produced  by  unihex2png  before  or  after
14       editing, and converts it back into a Unifont .hex format file.  The PNG
15       file contains a block of 256 Unicode code points arranged in a 16 by 16
16       grid.   Each code point appears in a 32 by 32 or a 40 by 40 pixel grid.
17       Characters are either 16, 24 or 32 pixel rows high,  depending  on  the
18       "-r"  parameter  specified by unihex2png.  They can be 8, 16, 24, or 32
19       pixel columns wide (widths of 32 are only supported for  32  pixel  row
20       tall characters).

OPTIONS

23       -i          Specify the input file.
24
25       -o          Specify the output file.  If omitted, a file in the Unifont
26                   .hex format is written to STDOUT.
27
28       -w width    Specify the minimum width of the output glyphs.  Valid val‐
29                   ues are 16, 24,
30                    and 32.  The default is no minimum width.
31
32       -h          Print a help message of options and exit.

AUTHOR

51       unipng2hex was written by Andrew Miller, starting  by  converting  Paul
52       Hardy's unibmp2hex C program to Perl.

BUGS

63       No known real bugs exist, but the optional pixel rows parameter is  not
64       yet  supported  by  all  other Unifont utilities.  Use of glyphs taller
65       than the default of 16 pixels is  considered  experimental.   Currently
66       unihex2png, unipng2hex, hexdraw, and hex2bdf tentatively support glyphs
67       that are 16, 24, and 32 pixels tall.
68
69       Also, this software does not perform extensive error  checking  on  its
70       input  files.   If they're not in the format of the original PNG output
71       from unihex2png, all bets are off.
72
73       If the output file is for a "page" containing space code points and the
74       PNG  file  squares for those code points are not empty, unipng2hex pre‐
75       serves the graphics as they are drawn.
76
77       unipng2hex is designed to work with black and white pixels; do not  use
78       other colors.
