NAME
    ppmlabel - add text to a portable pixmap

SYNOPSIS
    ppmlabel [-angle angle] [-background transparent | colour] [-colour
  colour] [-file filename] [-size textsize] [-text 'text
  string'] [-x column] [-y row] ... [ppmfile]

DESCRIPTION
    ppmlabel  uses the text drawing facilities of ppmdraw to add text to a
    portable pixmap.  The location, size, baseline angle, colour of the
    text and background colour (if any) are controlled by command line ar-
    guments.  The text can be specified on the command line or read from
    files. Any number of separate text strings can be added by one invoca-
    tion of ppmlabel, limited only by the maximum length of the command
    line.

    If no ppmfile is specified, ppmdraw reads its input pixmap from stan-
    dard input.

OPTIONS
    The arguments on the ppmlabel command line are  not options in the
    strict sense; they are commands which control the placement and appear-
    ance of the text being added to the input pixmap.  They  are executed
    left to right, and any number of arguments may appear.

    All flags can be abbreviated to their shortest unique prefix.

    -angle angle
   Sets the angle of the baseline of subsequent text. angle is
   specified as an integral number of degrees, measured counter-
   clockwise from the row axis of the pixmap.

    -background transparent | colour
   If the argument is ``transparent'', text is drawn over the
   existing pixels in the pixmap.  If a colour is given (see the
   -colour switch below  for information on how to specify
   colours), rectangles enclosing  subsequent text are filled
   with that colour.

    -colour colour
   Sets the colour for subsequent text. The colour can be spec-
   ified in five ways:

   o A name, assuming that a pointer to an X11-style colour
   names file was compiled in.

   o An X11-style hexadecimal specifier: rgb:r/g/b, where r
   g and b are each 1- to 4-digit hexadecimal numbers.

   o An X11-style decimal specifier: rgbi:r/g/b, where r g
   and b are floating point numbers between 0 and 1.

   o For backwards compatibility, an old-X11-style hexadec-
   imal number: #rgb, #rrggbb, #rrrgggbbb, or #rrrrgggg-
   bbbb.

   o For backwards compatibility, a triplet of numbers sep-
   arated by commas: r,g,b, where r g and b are floating
   point numbers between 0 and 1.  (This style was added
   before MIT came up with the similar rgbi style.)

    -file filename
   Reads text from the file filename and draws it on successive
   lines.

    -size textsize
   Sets the height of the tallest characters above the baseline
   to textsize pixels.

    -text 'text string'
   Draws the given text string (which must be quoted if it con-
   tains spaces). The location for subsequent text is advanced
   by 1.75 times the current textsize, which allows drawing mul-
   tiple lines of text in a reasonable manner without specifying
   the position of each line.

    -x column Sets the column at which subsequent text will be left justi-
   fied. Depending on the shape of the first character, the ac-
   tual text may begin a few pixels to the right of this point.

    -y row  Sets the row which will form the baseline of subsequent text.
   Characters with descenders, such as ``y'', will extend  below
   this line.

BUGS
    Text strings are restricted to 7 bit ASCII. The text font used by ppm-
    draw doesn't include definitions for 8 bit ISO 8859/1 characters.

    When drawing multiple lines of text with a non-transparent background,
    it should probably fill the space between the lines with the background
    colour. This is tricky to get right when the text is rotated to a non-
    orthogonal angle.
