Ligatures fontforge1/1/2023 ![]() ![]() This is a standard ligature for the latin script. "f" + "f" + "i" should turn into "ffi", while the feature would say that So in the example above the lookup would contain the information that World outside the font about what that set of lookups can be expected toĭo. Is a collection of lookups and is a provides semantic information to the Of tables in the font which contain transformation information. In OpenType this is handled by lookups and features. In the font to say that the glyph is a ligature, and to say what components Simply creating a ligature glyph is not enough. Once you have named your ligature, and inserted its components (with BuildĬomposite), you probably want to open the glyph, "longs_longs_l", if you want to build a ligature out of Unicode 0D15, 0D4DĪnd 0D15 then name it "uni0D15_uni0D4D_uni0D15". If you want to buildĪ ligature out of the glyphs "longs", "longs" and "l" then name it Out that it is a ligature and what its components are. Name is important, if you name it correctly FontForge will be able to figure #LIGATURES FONTFORGE CODE#First addĪn unencoded glyph to your font (or if your font is a Unicode font, youĬould use a code point in the private use area), and name the glyph. There are a good many ligatures needed for the indic scripts, but Unicodeĭoes not provide an encoding for them. (Only Apple Advanced Typography and OpenType support this). Press the button and drag one of the caret lines to its correct location. Ligature you might want to move the pointer tool over to the origin line, Them on the origin FontForge will ignore them. FontForge places these on the origin, if you leave Is a ligature it will insert in it enough caret location lines to fit between As soon as FontForge notices that a glyph This it must have some information from the font designer giving the locations But if the word processor is to be able to do With a ligature and sees behavior very similar to what s/he would see if That the user of that word processor does not need to know s/he is dealing ![]() (with a caret position between each component of the ligature). Some word processors will allow the editing caret to be placed inside a ligature Here theįinally drag the ligature caret lines from the origin to more appropriate Then useĬomposite to insert references to the ligature components.Ĭommand to turn the references into a set of contours.Īdjust the components so that they will look better together. This makes it slightly easier (at least in latin) to design a ligature.ĭialog to name the glyph and mark it as a ligature. Again Unicode providesĪ database listing the components of each standard ligature.įontForge cannot create a nice ligature for you, but what it can do is putĪll the components of the ligature into the glyph with Unicode contains a number of ligature glyphs (in latin we have: Æ, You may need to adjust one or two (or you may even want to redesign So you should be prepared to look at your accented glyphs after creating (if the one of the two stems of "u" is slightly taller than the other theĪccent will be placed over it rather than being centered over the glyph), Over the highest point of the glyph), sometimes this will produce bad results This range which are not accented, and they will remain blank).įontForge has a heuristic for positioning accents (most accents are centered Glyphs at encodings 0xc0-0xff, and then pressĪll the accented glyphs will magically appear (there are a few glyphs in ![]() Glyph in Unicode and FontForge uses this).Īs an example, open the file: tutorial/Ambrosia.sfd, then select all the (The UnicodeĬonsortium provides a database which lists the components of every accented In "Ã" and then positioning the accent over the "A". Then if you change the shape of the A the shape of the A in "Ã" willīe updated automagically - as will the width of "Ã".īut FontForge knows that "Ã" is built out of "A" and the tilde accent,Īnd it can easily create your accented glyphs itself by placing the references It Into, and then again adjust the position of the accent over the A. The letter "A" you will need to regenerate all the accented glyphs builtĪ Reference to "A", and Paste it, the Copy a Reference to tilde and Paste This mechanism is not particularly efficient, if you change the shape of Then you open up "Ã" and position the accent so that it appears properly While Paste Into merges what was in the glyph with the what is in the clipboard). Paste clears out the glyph before pasting, The most obvious mechanism is simple copy and paste: Latin, Greek and Cyrillic all have a large complement of accented glyphs.įontForge provides several ways to build accented glyphs out of base glyphs.
