@The Gamemaster:
Woops. I misunderstood how -follow works. Still, probably better to use -L.

@Yoda:
Nice catch.

‘-follow'

This option forms part of the “expression” and must be specified after the file names, but it is otherwise equivalent to ‘-L'. The ‘-follow' option affects only those tests which appear after it on the command line. This option is deprecated. Where possible, you should use ‘-L' instead.
If the it is otherwise equivalent to `-L' clause is true (which, as far as I can tell it is), then why is it followed by further qualifications.

If The ‘-follow' option affects only those tests which appear after it on the command line. were true, then a -follow at the end of a command would have no effect. If this were correct, then Yoda's -follow would have no effect since it occurs at the end of a command line, with nothing to affect after it.

I just ran a few tests and confirmed that Yoda's find does indeed work. In my opinion, that success contradicts the GNU find manual.

This is not something that troubles me deeply, since I don't depend on a GNU userland; I just thought it might be worth pointing out.

ppmtosixel

ppmtosixel(1)                                                 General Commands Manual                                                ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.  The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
              pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order  of  magni-
              tude larger than a compressed file and prints much slower.

       -margin
              If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
              fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater  than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
