       ppmlabel - add text to a portable pixmap

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

       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

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

       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-

                 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

       -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.

       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.

       The -size, -x, and -y options MUST precede the -text option  specifying
       the  string they apply to, or they will be silently ignored in favor of
       the defaults.
