The sequence to make a font using paintfont, charfill, adjustfont, and totype1, goes like this:

1. paintfont new.of
2. charfill new.of
3. adjustfont new.of adj.of
4. totype1 adj.of FONTNAME 1.0
5. cp FONTNAME /usr/lib/DPS/outline/base
6. modify showcase fontmap in /usr/lib/showcase/font.map

adjust the character spacing and position of characters in a font (adjustfont);
convert Adobe font metric files into TEX font metrix files (afm2tfm);
make an .sgo object or some extruded text (bevelstring);

draw antialiased text using a polygonal outline font (charfill);
check a font for self intersections (checkfont);
use widths from one typeface in another font (clonewid);

create a set of screen slides of filled polygonal fonts (fntslide);
make an image of a string of text (fontimg);
test object fonts (fonttest);
convert a .pfa font into the Hex format (frompfa);

convert an Adobe type 1 font into .of or .sf format (fromtype1);
turn an outline font into a triangle mesh (meshfont);
convert Type1 font from resource part of mac file into an ascii Type1 font (mfrc);
run an interactive font creator paint program to create your own fonts (paintfont);
print out a text description of a font (printfont);
decode an encrypted type1 font (rawtohex);
read font data out of the resource fork of a macintosh file (restoraw);
simplify a font by removing similar verticies (simpfont);
make lower case chars print as small caps (smallcaps);
turn an outline font into a texture map (texfont);
use texture mapping to draw text made by texfont (textmap).
convert an outline font into a PostScript font (totype1);
eliminate duplicate points on a .of file (undup);
and/or warp outline font geometry (warpfont);

Adjust an object font.
this program may be used to adjust the character spacing and position of characters in a font.

Try:

adjustfont ../fonts/cave.of out.of

Use the up and down arrow keys or depress the middle mouse to flip through the characters in the font. Use the left mouse button to adjust character offsets. Hold down shift and use the left mouse to adjust character widths.

Convert Adobe font metric files into TEX font metrix files.
This program converts AFM files to TeX TFM files, and optionally to TeX VPL files that retain all kerning and ligature information. Both files make the characters not normally encoded by TeX available by character codes greater than 127.

The afm2tfm.1 raw man page is included in this directory as well as a "baked" version stored in afm2tfm.txt.

Make an .sgo object of some extruded text.
this creates extruded beveled characters from a spline of polygon font.

Try:

bevelstring ../fonts/cave.of string.sgo "Hi there"
../objtools/spin string.sgo

Make a font bold by convolving with a line.

Fill characters in a font.
this program draws antialiased text using a polygonal outline font.

Try:

charfill ../fonts/haeberli-oblique.of

If you type, characters will be drawn from the typeface. You can use the up and down arrow keys to change the point size on the screen. The left mouse button clears the screen, while the middle mouse button will cause all the characters in the typeface to be drawn

Check a font for self intersections!!

Use widths from another font.
this copies widths from one typeface to another.

Draw an object font.
this displays a typeface in a window.

Try:

drawfont ../fonts/fat.of

Use LEFTMOUSE and slide left to right to see a character big;
press MIDDLEMOUSE and drag around to see a maginified verison of character.

Make text slides.
this is an example application that fills polygonal fonts and is VERY USEFUL for whipping up slides to fill the entire graphics console.

Try:

fntslide

PAGEDOWN advance to slide n+1
PAGEUP go back to slide n-1
LEFTMOUSE move through the entire set of slides
ESCKEY exit

You need be sure the "slide.mf" file is in the same directory with fntslide when you invoke fntslide.

______________________________________________________________
fontimg.c usage: fontimg font.{of, type1} pixhigh out.bw xsize ysize
string xoffset linewidth

Make an image of a string of text.

Test object fonts.
this demonstrates drawing filled and outlined text.

Convert a .pfa font into the Hex format.

Convert a .psf font into the Hex format.
this program converts a .psf font into the hex format.

Convert an Adobe type 1 font into .of or .sf format.
this converts an Adobe Type1 font into a spline or polygonal font in sgi format. The last argument is a flatness tolerance on the polygonal shapes. If this tolerance is set to 0.0, a spline version of the font is saved.

Try:

fromtype1 Times-Roman font.of 5.0

or

fromtype1 Times-Roman font.sf 0.0

Turn an outline font into a triangle mesh.

this converts a polygonal outline font into a triangle mesh font. When this is drawn, it will be filled in solid.

Try:

meshfont ../fonts/prim.of prim.mf
drawfont prim.mf

Sometimes this process will fail if the input typeface has outlines that self intersect. Some typefaces from Adobe have this problem.

this converts a Type1 font from the resource part of a mac file into an ascii Type1 font.

An interactive font creator.
this is a paint program that lets you create you own fonts!!!

To make a new font do:

paintfont new.of

And follow the instructions that the program prints out to the window you invoked paintfont in --

right side: left mouse draws; middle mouse clears; right mouse erases
left side: left mouse saves character data

left side: right mouse shows large character

brush diameter : up and down arrow keys
brush delay : left and right arrow keys
brush shape: F1 key cycles round->diag->square
press h to get this message

You can paint using the left mouse button. And then point to the character you want to define. Do this for the whole font, and then exit the program. Next run charfill on the font to see what it looks like, and then also use adjust font to tune the character spacing. Finally convert the font to Adobe type1 format using totype1.

If you move into the paintfont window, hold the shift key down, and click down the left mouse on one corner of an area on the screen and move to the opposite corner and release the mosse button and the shift key this area will be copied (with a slight scale) into the painting window.

Print an object font.
this prints a textual description of a font.

Decode an encrypted type1 font.

read font data out of the resource fork of a macintosh file.

simplify a font by removing similar verticies.
this can be used to eliminate fine detail in an outline font.

Make lower case chars print as small caps.

Turn an outline font into a texture map.

Try:

texfont fontname.of fontname.bw

to generate a texture-mapped image of the font and then, run textmap on it:

Use texture mapping to draw text.
demonstrates using a texture-mapped font to draw text. you must have a machine that supports texture mapping like a VGX or a REALITY ENGINE and then run,

textmap fontname.bw

Convert an outline font into a PostScript font.

Eliminate duplicate points on a .of file.
this removes duplicate vertexes from a polygonal font.

Warp outline font geometry.
this program can be used to add slope or jitter to a font.
