       pbmtext - render text into a bitmap

       pbmtext [-font fontfile] [-builtin fontname] [-space pixels] [text]

       Takes  the  specified  text,  either a single line from the command line or multiple lines
       from standard input, and renders it into a bitmap.

       In the bitmap, each line of input is a line of output.  Formatting characters such as new-
       line have no effect on the formatting; like any unprintable character, they turn into spa-

       The bitmap is just wide enough for the longest line of text, plus margins, and  just  high
       enough  to  contain the lines of text, plus margins.  The left and right margins are twice
       the width of the widest character in the font; the top and bottom margins are  the  height
       of  the	tallest character in the font.	But if the text is only one line, all the margins
       are half of this.

	      By default, pbmtext uses a built-in font called bdf (about a 10  point  Times-Roman
	      font).  You can use a fixed width font by specifying -builtin fixed.

	      You  can	also specify your own font with the -font flag.  The fontfile is either a
	      BDF file from the X window system or a PBM file.

	      If the fontfile is a PBM file, it is created in a very specific way.  In your  win-
	      dow system of choice, display the following text in the desired (fixed-width) font:

		  M ",/^_[`jpqy| M

		  /  !"#$%&'()*+ /
		  < ,-./01234567 <
		  > 89:;<=>?@ABC >
		  { \]^_`abcdefg {
		  } hijklmnopqrs }
		  ~ tuvwxyz{|}~  ~

		  M ",/^_[`jpqy| M

	      Do  a  screen grab or window dump of that text, using for instance xwd, xgrabsc, or
	      screendump.  Convert the result into a pbm  file.   If  necessary,  use  pnmcut  to
	      remove  everything  except  the text.  Finally, run it through pnmcrop to make sure
	      the edges are right up against the text.	pbmtext can  figure  out  the  sizes  and
	      spacings from that.

       -space pixels
	      Add  pixels  pixels  of  space between characters.  This is in addition to whatever
	      space surrounding characters is built into the font, which  is  usually  enough  to
	      produce a reasonable string of text.

	      pixels  may  be  negative  to  crowd text together, but the author has not put much
	      thought or testing into how this works in every possible case, so  it  might  cause
	      disastrous results.

       Often,  you  want  to place text over another image.  One way to do this is with ppmlabel.
       ppmlabel does not give you the font options that pbmtext does, though.

       Another way is to use pbmtext to create an image containing the text, then use pnmcomp  to
       overlay	the  text  image onto your base image.	To make only the text (and not the entire
       rectangle containing it) cover the base image, you will need to give pnmcomp a  mask,  via
       its  -alpha  option.   You  can just use the text image itself as the mask, as long as you
       also specify the -invert option to pnmcomp.

       If you want to overlay colored text instead of black, just use  ppmchange  to  change  all
       black  pixels to the color of your choice before overlaying the text image.  But still use
       the original black and white image for the alpha mask.

       If you want the text at an angle, use pnmrotate on the text image (and alpha mask)  before
