Packages

Egami is a family of packages. Each is fully managed C# with no dependencies outside the family, and you add only the ones you use. Packages at 1.0 or above keep their public API compatible within the major version; packages at 0.x may still change. Egami, Egami.Drawing, Egami.Fonts, Egami.Svg, Egami.Css, Egami.Heic, Egami.Formats.Extended, Egami.Cli and Egami.Cli.Host share one version and release together; the other packages have versions of their own. Each package name links to its source code.
