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 arguments.  The text can be specified on the command line or
       read from files.  Any number of separate text strings can be added by  one  invocation  of
       ppmlabel, limited only by the maximum length of the command line.

       If no ppmfile is specified, ppmdraw reads its input pixmap from standard input.

OPTIONS

       The  arguments  on the ppmlabel command line are not options in the strict sense; they are
       commands which control the placement and appearance 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 counterclockwise 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 specified in five ways:

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

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

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

                 ·      For  backwards  compatibility, an old-X11-style hexadecimal number: #rgb,
                        #rrggbb, #rrrgggbbb, or #rrrrggggbbbb.

                 ·      For backwards compatibility, a triplet of numbers  separated  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 contains  spaces).   The
                 location  for  subsequent  text  is advanced by 1.75 times the current textsize,
                 which allows drawing multiple 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 justified.  Depending on
                 the shape of the first character, the actual 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 ppmdraw 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.
