NAME

       pamtopdbimg - convert a Netpbm image to a Palm Pilot Image Viewer PDB Image

SYNOPSIS

       pamtopdbimg

       [-notefile=filename]   [-title=text]   [-compressed]   [-uncompressed]  [-maybecompressed]
       [-4depth] [-fixedtime]

       [netpbmfile]

DESCRIPTION

       This program is part of Netpbm(1).

       pamtopdbimg reads a Netpbm image as input and produced a Palm  Pilot  Image  Viewer  image
       (and Image record in a PDB file) as output.

       If  the  Netpbm  image  is black and white, the Pilot image is monochrome.  Otherwise, the
       Pilot image is either 4-level or 16-level grayscale, depending on the -4depth option.

OPTIONS

       In addition to the options common to all programs based on libnetpbm (most notably -quiet,
       see
        Common Options ⟨index.html#commonoptions⟩ ), pamtopdbimg recognizes the following command
       line options:

       -title=text
              The title of the image, to be included in the image.

       -compressed

       -uncompressed

       -maybecompressed
              You may specify only one of these.  -compressed  says  to  generate  the  image  in
              compressed  format.   -uncompressed  says  to  generate  the  image in uncompressed
              format.  -maybecompressed  says  to  generate  whichever  format  is  smaller  (the
              compression algorithm sometimes actually makes the data larger).

       -4depth
              This  option  makes  pamtopdbimg create the image in 16-level grayscale (4 bits per
              pixel) format.  If you don't specify this, pamtopdbimg uses  4-level  (2  bits  per
              pixel) format.

              This  option  has  no effect when the input is black and white (maxval 1).  In that
              case, pamtopdbimg generates the monochrome (1 bit per pixel) format regardless.

       -notefile=filename
              Attach the note in the specified file to the image.

              If you don't specify this, pamtopdbimg does not attach any note.

       -fixedtime
              Fake the mtime and ctime vaues in the PDB image with a value that is the same every
              time  you  run  the  program.  This facilitates testing and verification because it
              means with the same input you always get the same output.

              This option was new in Netpbm 10.98 (March 2022).

HISTORY

       pamtopdbimg was new in Netpbm 10.52 (September 2010).   It  was  modelled  after  Eric  A.
       Howe's imgvtopbm package, which dates back to September 1997.
