Reliable delivery of fonts is a requirement for SVG. Designers need to create SVG content with arbitrary fonts and know that the same graphical result will appear when the content is viewed by all end users, even when end users do not have the necessary fonts installed on their computers. This parallels the print world, where the designer uses a given font when authoring a drawing for print, and the graphical content appears exactly the same in the printed version as it appeared on the designer's authoring system.
Typically, the WebFonts are saved in a location relative to the referencing document. One disadvantage to the WebFont facility to date is that specifications such as CSS2 do not require support of particular font formats. The result is that different implementations support different Web font formats, thereby making it difficult for Web site creators to post a single Web site using WebFonts that work across all user agents.
This facility is called SVG fonts. SVG fonts can improve the semantic richness of graphics that represent text. For example, many company logos consist of the company name drawn artistically. The purpose of SVG fonts is to allow for delivery of glyph outlines in display-only environments. SVG fonts that accompany Web pages must be supported only in browsing and viewing situations.
Graphics editing applications or file translation tools must not attempt to convert SVG fonts into system fonts.
Instead, each content creator will need to license the given font before being able to successfully edit the SVG file. SVG fonts contain unhinted font outlines. Because of this, on many implementations there will be limitations regarding the quality and legibility of text in small font sizes.
For increased quality and legibility in small font sizes, content creators may want to use an alternate font technology, such as fonts that ship with operating systems or an alternate WebFont format.
Because SVG fonts are expressed using SVG elements and attributes, in some cases the SVG font will take up more space than if the font were expressed in a different WebFont format which was especially designed for compact expression of font data.
For the fastest delivery of Web pages, content creators may want to use an alternate font technology. In some situations, it might be appropriate for an SVG font to be the first choice for rendering some text.
In other situations, the SVG font might be an alternate, back-up font in case the first choice font perhaps a hinted system font is not available to a given user. In this model, various font metrics, such as advance values and baseline locations, and the glyph outlines themselves, are expressed in units that are relative to an abstract square whose height is the intended distance between lines of type in the same type size.
This square is called the em square and it is the design grid on which the glyph outlines are defined. Unlike standard graphics in SVG, where the initial coordinate system has the y-axis pointing downward see The initial coordinate system , the design grid for SVG fonts, along with the initial coordinate system for the glyphs, has the y-axis pointing upward for consistency with accepted industry practice for many popular font formats.
SVG fonts and their associated glyphs do not specify bounding box information. Because the glyph outlines are expressed as SVG graphics elements, the implementation has the option to render the glyphs either using standard graphics calls or by using special-purpose font rendering technology, in which case any necessary maximum bounding box and overhang calculations can be performed from analysis of the graphics elements contained within the glyph outlines. An SVG font can be either embedded within the same document that uses the font or saved as part of an external resource.
First referenced SVG font file:. These two alternatives are processed differently see below. CSS2 selectors can be applied to the original i. CSS2 selectors cannot be applied to the conceptually cloned DOM tree because its contents are not part of the formal document structure.
The team behind FontSelf created this excellent guide over on colorfonts. To see what web browsers support SVG fonts, plus a bunch of other great information, visit colorfonts.
In Photoshop you must be in RGB color mode, and apply a color overlay. This is done by using your layers panel to add a Layer Style fx. In Illustrator you must also be in RGB color mode.
At large sizes they may pixelate. If you have more tips or tricks to share when it comes to using OpenType SVG fonts, comment below or send as email at hello pixelsurplus. By downloading free items from Pixel Surplus you agree to receive communications via our newsletter.
With the rising number of service providers for web fonts such as Google fonts , Font Squirrel , etc. Pros: Wide selection of fonts available. There's more than fonts in Google, and rest assured, the list will continue to grow.
But this can be easily negated by using Nano to embed optimized fonts into your SVG so it works well on any browsers, while maintaining a small SVG file size. Comment below on your common practices of using fonts in SVG and if there's any best practices to share!
Founder at vecta. There are currently 3 different ways to use fonts in SVG. Using SVG fonts When the SVG standard was first devised, web fonts usage was not easily accessible among browsers causing typography issues. Using web-safe fonts Using web-safe fonts ensures fonts in SVG is displayed in most major systems and this is by far the easiest approach. Using web fonts Using web fonts is by far the best way to ensure cross-browser support in SVG with support from Microsoft IE6 all the way to the latest browsers.
This should covers all the available methods of using fancy fonts in your SVG.
