If it is documented, please feel free to send a link! If not, I'm hoping you'd be willing to share your perspective and insights on this.
I've searched around the issues here, but couldn't find documented reasoning around this. I imagine you probably have a good reason for using calt, but I wanted to clarify my understanding of why.
#G DOCS LIGATURES CODE#
Lining numbers are commonly used in tables and forms.Hey Nikita, I am looking into implementing code ligatures in a font of my own, and as I'm thinking through it, I've come to a question: might it make more sense (and fit the OpenType spec better) for code ligatures to use discretionary ligatures ( dlig) rather than contextual alternates ( calt)? In Lining number form all numbers have the same height. Number Form Optionsĭefault: For this option based on the font selected the default number form specified for that particular font will be applied. Cambria, Calibri and Consolas fonts comes with tabular spacing by default. This is especially useful when using tables as the numbers will be aligned equally in a column irrespective of its width. In this option each number is given the same space or width.
Three fonts that use proportional spacing by default are Candara, Constantia and Corbel. For example 1 and 2 are proportionally spaced as 1 requires less space when compared to 2. Number Spacing Optionsĭefault: For this option based on the font selected the default number spacing specified for that particular font will be applied.Īs the name suggests numbers are spaced proportionally based on its width. Both these ligatures are not used commonly but only for certain sections of the text based on specific needs.Īll: In this option all ligature combinations that are available for a particular font will be applied to the text. Historical and Discretionary: Historical ligatures are usually used for that “period” effect and Discretionary ligatures are used for specific purposes. The combination of standard and contextual ligatures gives you the set of ligatures which can be used commonly. Standard and Contextual: Contextual ligatures as the name suggests are based on specific fonts and can be used with only those fonts. The standard set of ligatures contains the most commonly used ligatures like “f” and “t” but it varies based on language. To enable OpenType ligatures type some text in OpenType font like “Calibri” in a document.įrom Home | Font choose the ‘WordArt’ pull-down menu to Ligatures: For this reason we’ll be using Gabriola in all these examples. Gabriola font supports advanced OpenType features with extensive use of stylistic sets. Not all fonts are OpenType and not all OpenType fonts include Ligatures. OpenType was developed by Microsoft and Adobe. OpenType is a relatively new format for scalable computer fonts that’s replacing the stalwart of Window fonts, TrueType. Most common ligatures are ff, fl, fi, ffi and ffl.Ĭombining the “f” and “i” or “f” and “l” into a single letter makes the “f” look more stable rather than giving an impression of falling on “i” or “l”. Ligatures avoid the unattractive collision that occurs in some typefaces. About LigaturesĪ Ligature is a special character that combines two or three letters into a single character or glyph. Not all ligatures and styles need to be so extreme and they are best used sparingly and subtly. Gabriola font normal (top) and with Ligatures – style set 7 (bottom)
