pbmtopk - convert a PBM image into a packed (PK) format font


pbmtopk pkfile[.pk] tfmfile[.tfm] resolution [-s designsize] [-p num param...] [-C codingscheme] [-F family] [-f optfile] [-c num] [-W width] [-H height] [-D depth] [-I ital] [-h horiz] [-v vert] [-x xoff] [-y yoff] [pbmfile ...]


This program is part of Netpbm(1)

pbmtopk reads PBM images as input and produces a packed (PK) font file and a TFM (TeX font metric) file as output. The resolution parameter indicates the resolution of the font, in dots per inch. If the filename ’-’ is used for any of the filenames, pbmtopk uses Standard Input or Standard Output.


-s designsize
 Sets the design size of the font, in TeX’s points (72.27pt to the inch). The default design size is 1. The TFM parameters are given as multiples of the design size.

-p num param...
 Sets the first num font parameters for the font. The first seven parameters are the slant, interword spacing, interword space stretchability, interword space shrinkability, x-height, quad width, and post-sentence extra space of the font. Math and symbol fonts may have more parameters; see The TeXbook for a list of these. Reasonable default values are chosen for parameters which are not specified.

-C codingscheme
 Sets the coding scheme comment in the TFM file.

-F family
 Sets the font family comment in the TFM file.

-f optfile
 Reads the file optfile, which should contain a lines of the form:

filename xoff yoff horiz vert width height depth ital

The PBM files specified by the filename parameters are inserted consecutively in the font with the specified attributes. If any of the attributes are omitted, or replaced with ’*’, a default value will be calculated from the size of the bitmap. The settings of the -W, -H, -D, -I, -h, -v, -x, and -y options do not affected characters created in this way. The character number can be changed by including a line starting with ’=’, followed by the new number. Lines beginning with ’%’ or ’#’ are ignored.

-c num Sets the character number of the next bitmap encountered to num.

-W width
 Sets the TFM width of the next character to width (in design size multiples).

-H height
 Sets the TFM height of the next character to height (in design size multiples).

-D depth
 Sets the TFM depth of the next character to depth (in design size multiples).

-I ital
 Sets the italic correction of the next character to ital (in design size multiples).

-h horiz
 Sets the horizontal escapement of the next character to horiz (in pixels).

-v vert
 Sets the vertical escapement of the next character to vert (in pixels).

-x xoff
 Sets the horizontal offset of the next character to xoff (in pixels).

-y yoff
 Sets the vertical offset of the next character to yoff (in pixels, from the top row).
