Icon types

There are 3 types of icon items in IconSet: "icon", "variation", "alias".

"icon" represents a full unique icon.

"variation" represents variation of another icon. It has the following properties:

  • parent, string. Name of parent icon.

and at least one of the transformations:

  • rotate rotation by 90, 180 or 270 degrees.
  • hFlip horizontal flip.
  • vFlip vertical flip.

Variations make it easy to create clones of icons, such as arrow-left after creating arrow-right.

"alias" is an alternative name for icon. It has the following property:

  • parent, string. Name of parent icon.

Aliases can be created to have different name for icon. If you have renamed some icon, alias can be used to allow users to use old name.
