FONTIMAGE(1) General Commands Manual FONTIMAGE(1)NAME
fontimage - produce a font thumbnail image
SYNOPSIS
fontimage [--help] [--width num] [--height num] [--pixelsize num] [--text string] [--o outputfile] [--usage] [--version] fontfile
DESCRIPTION
The program fontimage loads a font, which may be in any format fontforge(1) can read, and then produces an image showing representative
glyphs of the font.
OPTIONS --help Provide a description with a list of the available options.
--width num
Specifies the width of the output image. If this is omitted the image will be as wide as necessary to display the text.
--height num
Specifies the height of the output image. If this is omitted the image will be as high as necessary to display the text.
--pixelsize num
Specifies the pixelsize used to display the text. This argument may be specified multiple times and each refers to any --text lines
that follow it.
--text string
Specifies a line of text to be displayed. The string must be in UTF-8. This argument may be specified multiple times to provide
several lines of text. If no --text arguments are supplied fontimage will examine the font, looking for various scripts it knows
about, and will try to display something appropriate for each.
-o outfile
Specifies the output filename for the image. The type of image will be determined by the file's extension. Currently only ".bmp" and
".png" are recognized. If omitted fontimage will choose an output name based on the font's fontname field.
--usage
Display the usage description.
--version
Display the current version

pbmtext(1) General Commands Manual pbmtext(1)NAME
pbmtext - render text into a bitmap
SYNOPSIS
pbmtext [-font fontfile] [-builtin fontname] [-space pixels] [-lspace pixels] [text]
DESCRIPTION
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 newline have no effect on the formatting; like any
unprintable character, they turn into spaces.
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.
OPTIONS -font,-builtin
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 specify-
ing -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 window system of choice, display the following text in
the desired (fixed-width) font:
M ",/^_[`jpqy| M
/ !"#$%&'()*+ /
< ,-./01234567 <
> 89:;<=>?@ABC >
@ DEFGHIJKLMNO @
_ PQRSTUVWXYZ[ _
{ ]^_`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 pos-
sible case, so it might cause disastrous results.
-B -lspace pixels
Add pixels pixels of space between lines. This is in addition to whatever space above and below characters is built into the font,
which is usually enough to produce a reasonable line spacing.
pixels must be a whole number.
pixels may be negative to crowd lines together, but the author has not put much thought or testing into how this works in every pos-
sible case, so it might cause disastrous results.
USAGE
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 overlaying.
