••• FONTOGRAPHER 4 TECHNICAL NOTES August 31, 1993•••
••• HINTING •••
—Improved TrueType Hinting
For converting PostScript fonts into TrueType fonts, use these steps
to produce the fuller range of hints needed to generate a properly
instructed TrueType font:
1. Select all the characters in the Font Window.
2. In the “Hints” menu, select “Vertical Alignment Zones…”
3. Press the “Recompute” button and then press “OK.”
4. Once again, go to the “Hints” menu and select “Autohint” if it is
not already checked.
Now full TrueType hinting will be applied to your font when it is
generated.
We have implemented the equivalent of the ‘vstem3’ hint for TrueType
fonts. This can greatly improve the “m.” The rules are the same as for
Type 1—you must have three vertical stem hints; all the outer hints
must be exactly the same width; and the distance from the center of the
outer hints to the center of the central hint must be equal. If these
conditions are met, the three stems will be hinted together and
preserve the symmetry of the stems.
••• TRUETYPE •••
—TrueType Spacing in MacWrite II
We discovered that some TrueType fonts will have better spacing when
MacWrite II has fractional widths turned on.
—“Include extra TrueType tables” button in TrueType options in the
“Generate Font Files…” dialog
When a TrueType font is read into Fontographer, all the tables in the
font are stored in the database. Some of these tables may be unique to
specific formats, such as GX or Windows. In most cases the extra tables
do not need to be in the TrueType output from Fontographer. For
example, if you open a GX font and want to output it as a Windows
TrueType, then you would not want to include the extra tables since
they would be superfluous and possibly confusing to Windows. However,
in cases where you will be outputing a modified GX font, you’ll want
those tables generated with it. However, Fontographer does not change
the contents of these extra tables, so if the glyph numbers have
changed the data may no longer be valid.
••• EMBEDDING PC TRUETYPE FONTS IN DOCUMENTS •••
Assume that you have created a font and want to send a document to an
associate across the world who does not own your font. But you do want
that document printed in your font. Font embedding — or encapsulation —
is your solution. There are three levels of font encapsulation. The
most common level is “none” or “full protection.” Such a font cannot
be sent with the file. The next level is “read-only.” In this case, the
document can be viewed and printed by the associate who does not have
the font, but they can’t make changes. The ultimate level is
“read-write” embedding which allows for full re-editing of the document
in the original font. Essentially, the whole font is sent along for
easy retrieval. These embedding values can be applied to the font after
it is compiled using PC Font Access (automatically installed with
Fontographer). But you can also have Fontographer apply the encapsulation
when you generate the font. Fontographer determines which level is
desired by parsing the “Notice:” field in “Font Info”. If you want
“read-write” encapsulation, you’ll need to type “RWE” at the end of
your copyright notice. For “read-only” embedding, type “ROE”. For “full
protection” — no font embedding — then do nothing special; just type in
your regular notice. If the “Notice:” field is blank, then “read-write”
encapsulation is assumed.
••• MAKING THE BEST USE OF FONT BLENDING •••
For best results, we recommend beginning with a “Clean Up Paths” of all
the characters that you wish to blend.
After blending you might get a dialog telling you how unsuccessful your
attempt was. Don’t panic. It is normal for some characters to fail.
Some characters may be garbled. Go to one such character in the two
source fonts, and follow these instructions:
1. Merge points to remove any extra points. You may have to do another
“Clean Up Path.”
2. Set the origin point at the lower right of the character, using the
“Selection Info” dialog after selecting that point. In some serif
fonts, Fontographer’s “Blend Fonts” thinks that the serif contains the
lower right point, and will set the origin there. By setting the origin
at the lower right of the character, instead of the serif, you will
override that.
3. If you have more than one path, do a “Correct Path Direction” for
the source characters.
4. Make sure that the paths are in the same order. (In Fontographer 4.0
the Arrange menu’s “Send to front” option marks the path as last.)
5. Now try “Blend Fonts” again on that character. Click the radio
button for “Select characters of destination font.” Click off the
checkbox for “Correct path direction first.”
If that does not solve the problem then other measures are necessary:
1. Select from “Preferences” the point display popup menu that shows
labels for all points. This will let you to see the order of the
points.
2. Insert similar kinds of points in the same order and position in
each source character and try again. This time also turn off the
checkbox “Insert points to match.”
If your fonts do not have the same ascent/descent you may have to
change these settings in the “Font Info” dialog. You also may have to
adjust how the characters fit on the baseline.
NOTE: If the two source characters have a different number of paths,
Fontographer will not blend them.
••• METRICS •••
—Metrics Assistance
While Metrics assistance is a great help in quickly spacing similar
characters, it is not bullet proof. It is possible to make an
equivalence between a first character and a second character, and then
make a different equivalence between that same second character and the
first character. Fontographer will let you do something like that, but
the results will not always be pleasing.
If you want to use the “File” button in Auto Kern, you must select an
AFM, or Altsys metrics file. It is much like “Importing metrics”
(kerning only).
—Auto Spacing
“Adjust left sidebearings” will move accents of referenced characters.
If you need the left adjusted, then first unlink the reference of all
your composite characters.
•••SOUNDS•••
Fontographer has the ability to play cool sounds during certain actions.
It plays sounds when you snap to a point or snap to a guide in the Outline
Window, and it plays a sound whenever the "Please Wait" dialog closes.
If you wish to use sounds in Fontographer you should do the following:
1) Find the file called “Fontographer Sounds” on the installation disks.
2) Place the file into the same folder as Fontographer.
3) Don't change the name of the file, because Fontographer looks for
that name specifically.
If you feel comfortable using ResEdit you can easily customize your sounds.
Here's how:
1) Get the sound you wish to use.
2) Convert the sound into a 'snd ' resource if necessary.
3) Use ResEdit to paste the snd resource into the “Fontographer Sounds”
file.
4) Then use ResEdit to name the resource as one of the following:
- “Snap to point”
- “Snap to guide”
- “Operation done”
(The spelling must be exact.)
That's it! Run Fontographer and you here the sounds. Have fun!!!
••• MULTIPLE MASTER •••
Multiple Master sample fonts are on the Fonts disk. They are in
compressed form. Since most people will never use them, we did not copy
them to your hard drive with the installation. If you’d like to dive
into Multiple Master fonts, there are a couple of things we recommend
you do first. Read the section in “Using Fontographer on your
Macintosh” about Multiple Master fonts. Get the Multiple Master system
extensions from Adobe, or get SuperATM®. You should have a working
knowledge of font hinting and the “Adobe Type 1 Font Format” book. Then
you can start looking at Fontographer’s multiple master feature and
have a clearer understanding of what it does.
••• LASERWRITER IINT and MULTIPLE MASTER FONTS •••
We have run afoul of the old “limited vertical stem widths bug” in
certain versions of PostScript in the LaserWriter IINT and PLW IINT. No
Multiple Master fonts, even Adobe’s own Multimaster fonts, will print
to our PLW IINT.
••• FONT ENCODING ON SUN® WORKSTATIONS •••
You may need to try both Adobe Standard and ISO Latin 1 encoding
vectors for your Sun fonts. Depending on the system you are using and
even the applications, you may see a difference in the character
mapping of characters in the upper ASCII range.
