reads a PNG file produced by

@b{unihex2png}
before or after editing, and converts it back into a Unifont .hex format
file. The PNG file contains a block of 256 Unicode code points
arranged in a 16 by 16 grid. Each code point appears in a 32 by 32 or a 40
by 40 pixel grid. Characters are either 16, 24 or 32 pixel rows high,
depending on the "@minus{}r" parameter specified by
@comment TROFF INPUT: .B unihex2png.
@b{unihex2png.}
They can be 8, 16, 24, or 32 pixel columns wide (widths of 32 are only
supported for 32 pixel row tall characters).

@subsection unipng2hex BUGS
@c DEBUG: print_menu("unipng2hex BUGS")
No known real bugs exist, but the optional pixel rows parameter is not
yet supported by all other Unifont utilities. Use of glyphs taller than
the default of 16 pixels is considered experimental. Currently
@comment TROFF INPUT: .B unihex2png, unipng2hex, hexdraw,
@b{unihex2png, unipng2hex, hexdraw,}
and
@comment TROFF INPUT: .B hex2bdf
@b{hex2bdf}
tentatively support glyphs that are 16, 24, and 32 pixels tall.
@comment TROFF INPUT: .PP
Also, this software does not perform extensive error checking on its
input files. If they're not in the format of the original PNG output from
@comment TROFF INPUT: .B unihex2png,
@b{unihex2png,}
all bets are off.
@comment TROFF INPUT: .PP
If the output file is for a "page" containing space code points and the
PNG file squares for those code points are not empty,
@comment TROFF INPUT: .B unipng2hex
@b{unipng2hex}
preserves the graphics as they are drawn.
@comment TROFF INPUT: .PP
@comment TROFF INPUT: .B unipng2hex
@b{unipng2hex}
is designed to work with black and white pixels; do not use other
colors.
