GlyphTypeFace: Specifies a physical font face that corresponds to a font file on the disk., useful to parse a.TTF file and build glyphs from it. GlyphRun: Represents a sequence of glyphs from a single face of a single font at a single size, and with a single rendering style, with many usefull properties and methods (for example, you can build. Press Start 2P is a bitmap font based on the font design from 1980s Namco arcade games. Although the design of uppercase letters and digits dates back to Atari's 'Sprint' (1977), the specific glyph forms in this TrueType conversion are based on those from 'Return of Ishtar' (1986), one of the first games to include and regularly use lowercase as well as uppercase letters in its screen font.
Font > Generate Glyphs is used for creating new glyphs when any of the following situations apply:
- You want to add a glyph with a custom or arbitrary name.
- You have base Latin glyphs and diacritical marks (accents) and you want the quickly build the combined accented glyphs, and you want more control than is offered by Add Glyphs
- You have two (or more) base glyphs and you want to add a ligature that refers to them.
- You want to create a set of alternates (small caps or some other set of glyphs) for OpenType layout.
- You know the standard glyph name you need, and do not want to search for it in Codepages, Encodings, etc.
If you want to add glyphs that correspond to standard Unicode characters, especially if there are many of them, Add Glyphs may be the right option instead.
With Generate Glyphs, you can choose whether the resulting glyphs should be simple, composite or auto glyphs .
Controlling the result of glyph generation»
There are several options in the left portion of the Generate Glyphs dialog:
Use anchors will make use of any Anchors you have created in the source glyphs to position them together. This is usually desirable, and is most commonly used for better positioning of diacritical marks (accents).
Link as references will create the generated glyphs using References to the Elements in the original glyphs. This too is commonly used for accented glyphs, and sometimes for ligatures as long as no changes are needed to the elements.
Rebuild existing glyphs will cause FontLab to overwrite existing glyphs, if the new glyphs have the same names.
Create auto layers will generate the glyphs as auto glyphs : elements will be added as references, anchors will be used to position them if present in the primary glyphs, the advance width will be inherited from the base glyphs, and the contents of the generated glyphs will automatically fill and update over time as you add new base and mark glyphs. The recipes that you’ve used to generate the auto glyphs will be copied into the glyph recipe field of the glyphs’ auto layers.
Use legacy (FLS5) code (in “Custom” tab only): when turned on, FontLab VI will expect the glyph recipes to be written using the “legacy” syntax that was used in the “Generate Glyphs” dialog of FontLab Studio 5. When turned off, FontLab VI will expect the glyph recipes to be written using a syntax that is largely compatible with the GlyphConstruction syntax. When Create auto layers is turned on, you can use only the “legacy” glyph recipe syntax.
All masters vs Active master only: choose to generate the glyphs in all masters or only in the current master.
Open new glyphs for editing: when turned on, FontLab will generate the requested glyphs and then immediately open them for editing in a new Glyph window. When turned off, FontLab will just generate the glyphs.
Flag new glyphs (at bottom left) allows you to color-code the cells for your newly-generated glyphs, so you can distinguish them more clearly/easily from others.
There are five tabs under Generate Glyphs: Characters, Ligature, Variants, Precomposed and Custom. The first four tabs work based on a selection in the Font Window or the Glyph Window. The Custom tab allows you to type or paste your own glyph recipes using a special syntax.
Selection-based glyph generation»
If you select glyphs or empty glyph cells in the Font Window, or if you select some glyphs or characters (including those that don’t exist in the font yet) in a Glyph Window, you can use Generate Glyphs to build a series of Unicode characters, a ligature, a series of glyph variants or a precomposed glyph. To use the selection-based glyph generation, before you invoke Generate Glyphs:
- If you’re in the Font Window, select some glyph cells in the Font Window. You can include empty (gray) glyph cells in your selection if you have a particular encoding or codepage active in the Font Window.
- If you’re in the Glyph Window, do one of the following:
- type or paste arbitrary text using the Text tool
- type or paste text or glyphtext (using the
/glyphname
anduXXXX
notation) into the text field in the content sidebar - choose a text from the Text dropdown menu in the content sidebar
- choose a text from the Pairs and Phrases panel.
When the Text tool is active in the Glyph Window, you can optionally select some portion of the text visible in the Glyph Window. If another tool is active, the entire text visible in the Glyph Window will be treated as the selection.
The glyphs or text that you have selected will be treated as the input selection for the Generate Glyphs dialog, and depending on the Generate Glyph tab, FontLab will use different methods to interpret the input selection. When you have a selection, choose Font > Generate Glyphs. Now you can use one of the four tabs in the Generate Glyphs dialog to choose the glyph generation method:
Characters: this method will treat the input selection as a string of Unicode characters, so for every character in your input selection, FontLab will try to generate a new glyph. This method is most useful if you have a pre-existing text that contains various Unicode characters, and you’ve pasted that text into the Glyph Window (remember, you can always select just a portion of the text using the Text tool before invoking Generate Glyphs). Using the Characters tab is a very easy method to generate all glyphs required to render a particular Unicode text. So if your input selection was the text
fön
, FontLab will try to generate the glyphs f
, odieresis
and n
. Ligature: this method will form a ligature. It will generate exactly one glyph which horizontally combines the glyphs from the input selection. The advance width of the resulting glyph will be the sum of the advance widths of the input selection. So if your input selection was the text
fön
, FontLab will try to generate the glyph f_odieresis_n
. This method works sensibly if you type in some text in the Glyph Window and then select a few characters using the Text tool. Variants: this method will generate a series of glyphs that are intended to be variants of the glyphs from the input selection. This method works well if you made your input selection in the Glyph Window or in the Font Window. For each selected glyph, FontLab VI will try to generate a new glyph with identical contents and metrics, but adding a suffix to each glyph’s name. You can specify the suffix in the left portion of the dialog. So if your input selection was the text
fön
and you specify the suffix ss01
, FontLab will try to generate the glyphs f.ss01
, odieresis.ss01
and n.ss01
. Precomposed: this method will generate exactly one glyph which overlays all glyphs from the input selection into one glyph. The advance width of the new glyph will be equal to the width of the first glyph from the input selection. This method will position the overlaid glyphs using Anchors if they are present in the source glyphs.
Custom glyph generation»
The last tab of the Generate Glyphs dialog, Custom, allows you to enter (type or paste) your own glyph generation code using one of two code syntaxes: the legacy syntax and the extended syntax. See Glyph Recipe Syntax for more details.
Anchors in generated glyphs»
Auto layers and composite glyph layers inherit anchors from all component glyphs used to generate the layer, but without duplicated anchors.
For example: When FontLab generates the
Aringacute
manual or auto layer using the A+ringcomb+acutecomb
legacy glyph recipe, and all three component glyphs have a top
anchor, the final glyph will get the top
anchor from acutecomb
, placed accordingly. Anchors not present in acutecomb
will be inherited from ringcomb
, and finally, those not present there, from A
.Introduction
In some cases a font may lack a glyph that is essential for its use in your application. Arabic fonts present special issues here, because the shape of the glyph depends not only on its position in the word, but also on the attributes of the letter itself. Thus, using the nonsense sequence babab, the letter beh has three different shapes depending on whether it comes initially, medially, or finally. However, using the nonsense sequence dadad, the letter dal has only one shape, no matter where it occurs in the word.
Fonts under open licenses (e.g., GPL or OFL) allow the user to make modifications. If you adapt a font that was originally under an open license and then distribute it, you must retain the original author’s copyright notices and licensing information, although you can append a note at the end of the copyright notice covering your contribution.
This chapter walks through adding a glyph to an Arabic font. The font we will use is Graph, and the glyph we will add is peh (U+067E), which does not occur in Arabic itself, but designates p in some languages for which Arabic script is used. (For a full listing of the glyphs available for Arabic script, see the Unicode charts.)
Make a working copy of the font
Download the font from the webpage and unzip it. Launch FontForge and load the font. Save it as an sfd file, editing the suggested name to read GraphNew.sfd before saving.
Rename the font
Why should I rename the font?
If you do not rename the font, your adapted font will not install separately from the original — you will have to uninstall the original font first. It is also sensible to rename the font if you are going to distribute your adaptations — if the original author of the font has reserved the font name under the Reserved Font Name (RFN) mechanism, that original name can only be used with the original author’s version of the font.
Change the name data
Select Element > Font Info, and in the PS Names panel, change Fontname, Family Name, and Name For Humans to GraphNew.
If desired, you can place an ‘Additional glyphs added by’ message after the text already in the entry for Copyright.
In the TTF Names panel, the names for Family and Fullname are taken from the PS Names entries, and should already be showing GraphNew (you cannot edit them directly). Change the entries for Preferred Family and Compatible Full to GraphNew. These name changes will now allow you to install this font alongside the original one if you wish.
If desired, you can place an ‘Additional glyphs added by’ message after the text already in the entry for Designer.
Click OK to save these changes. You will get a message about generating a new UniqueID (XUID) for the font — click Change.
Add the glyph for the isolated form of peh
Go to the Arabic section of the font chart: select View — Go to, click the dropdown box and select Arabic, then click OK.
Clicking on a cell in the font chart will show its Unicode number and name in blue at the top of the panel. Go to position 1662 , which will show in blue as 1662 (0x67e) U+067E “uni067E” ARABIC LETTER PEH. The cell below the reference glyph contains a grey X, showing that the font does not include this glyph.
We will make peh by copying beh (U+0628) and swapping its single dot for three dots.
Click on the beh cell (position 1576), then right-click and select Copy. Then right-click on the peh cell and select Paste. Now that beh is now copied into the peh cell, the next thing is to change the dot.
Find a glyph with three dots — sheen (position 1588, U+0634) will do. Double-click on the cell — this will open a glyph design panel. Press V to ensure the pointer tool (arrowhead) in the toolbox is selected, and press Z and enlarge the panel to give you a good view of the glyph.
Click and drag so that the nodes of the three dots above sheen change color from pink to beige. If you accidentally include or omit a node, deselect or select it by pressing Shift and clicking. Press Alt + C to copy.
Go back to the font chart and double-click on the peh cell — this will load peh into another tab in the glyph design panel, alongside the sheen tab.

Click and drag to highlight the dot below peh, then press Delete. Press Alt + V to paste in the three dots, which will likely appear above the body of peh. Leave the dot nodes highlighted so that you can invert and move them more easily.
Invert the dots: select the flip tool (two triangles with a red dashed line between them) from the toolbox. (Alternatively, right-click in the middle of the dots, and select Flip the selection from the popup.) Click on one of the dot nodes and drag the mouse slightly left or right.
Move the inverted dots: press V to select the pointer tool again, click on one of the dot nodes, and drag them down below the body of the glyph. Position them centrally, above the ArabicBelow mark.
Close the glyph design panel. There should now be a new glyph for peh in the font chart. Save the adapted font (File > Save).
Add the glyphs for the connected forms of peh
However, this is only the isolated (standalone) form of the glyph. If you try to use your adapted font, you will find that initial, medial and final forms are not available. These have to be created separately.
The[se] forms are built as unencoded glyphs (glyphs whose encoding is -1 in FontForge conventions). Th[ey] have no predefined slots.” (Khaled Hosny)
Select Encoding > Add Encoding Slots and enter the number of the glyphs you want — in this case, 3. FontForge will add the same number of slots at the very end of the font, and you will be moved there in the font chart. The last three cells (positions 65537, 65538, 65539) have a question mark as a reference glyph, and it is in those cells that you will add the unencoded glyphs by repeating the process above.
Note that if by mistake you start typing when the font chart still has focus, you get moved to the European section at the top. To get back to the bottom, select View > Go to, click the dropdown box and select Not a Unicode Character, and then click OK.
Create the final form
Roll the font chart up a bit until you come to a set of Arabic glyphs at position 65152 (U+FE80) onwards. At U+FE90 (position 65168) you will see a behfinal glyph — click on it and press Ctrl + C to copy it. Roll down to the third last cell in the chart (position 65537), click on it, and press Ctrl + V to paste in the behfinal glyph.
Right-click on the cell and select Glyph Info. The naming convention is to use the number of the isolated glyph + a suffix for the form, so change Glyph Name to uni067E.fina, and click OK. The question mark in the reference cell will change to peh.
Get the three dots: double-click on sheen (U+FEB5) to load it into the glyph design panel, select the three dots and press Ctrl + C.
Double-click on the new pehfinal to load it into the glyph design panel, click and drag to highlight the nodes of the dot and press Delete.
Ctrl + V to insert the three dots from sheen, flip them, and move them into position below the glyph body. Press Ctrl + S to save the revised font chart.
Create the initial and medial forms
Copy the initial form U+FE91 (position 65169) to the penultimate cell (position 65538), delete the single dot and paste in the three dots. Cardhop 1 0 6 – manage your contacts without.
Right-click the cell, select Glyph Info, change Glyph Name to uni067E.init, and click OK.
Copy the medial form U+FE92 (position 65170) to the last cell (position 65539), delete the single dot and paste in the three dots.
Right-click the cell, select Glyph Info, change Glyph Name to uni067E.medi, and click OK.
Select File > Save to save the revised font chart.
Add the lookups
The isolated form has to be mapped (linked) to its initial, medial and final forms.
Select Element > Font Info > Lookups.
Click on the + beside the entry ‘init’ Initial Forms in Arabic lookup 2. This will open a submenu of the same name. Click on this submenu.
The Edit Data button on the right will now become available — click it.
In the Lookup Subtable panel that pops up, ensure that the Unicode button is checked. Roll the list of characters down until you come to the end.

In the box beside Default Using Suffix, enter the relevant suffix (in this case, init), and then click Default Using Suffix.
A new mapping will be added to the list of characters, from uni067E (the isolated form of peh) to uni067E.init (the initial form).Click OK.
Do the same for the submenus under the entries ‘medi’ Medial Forms in Arabic lookup 2 and ‘fina’ Terminal Forms in Arabic lookup 2, choosing medi and fina as the relevant suffix.
Click OK again to close the panel, and save the font chart (Ctrl + S).
Note that Default Using Suffix only seems to work on glyphs in the Unicode 06 (Arabic) block — glyphs in Unicode 07 (Arabic Supplement), e.g. ain with two dots may have to be added manually by clicking the line marked New and typing in the names.

Generate the adapted font
Select File > Generate Fonts.
In the dropdown showing PS Type 1 (Binary), select TrueType, and check that the filename reads GraphNew.ttf.
Navigate to where you want to save the font, and then click Generate. Click Yes and Generate to the two information messages that come up.

You can then use your normal font installation procedure to install the adapted font. The new glyph peh can then be used alongside the existing glyphs in the same nonsense examples as at the beginning of this chapter:
Note that if you are using a font in LibreOffice and make changes to that font, you need to restart LibreOffice to have it see any changes — otherwise it will use the previous version of the font, and not the one with the new changes.
Thanks to Khaled Hosny for his advice on using FontForge to edit Arabic glyphs.
