Interface: TransparencyGroupOptions

Options for transparency groups.

Transparency groups allow a set of drawing operations to be composited as a single unit before being blended with the page content.

Properties

optional colorSpace: "DeviceRGB" | "DeviceCMYK" | "DeviceGray"

Color space for the transparency group. Default: 'DeviceRGB'.

optional isolated: boolean

When true, the group is composited against a fully transparent backdrop rather than the existing page content. Default: true.

optional knockout: boolean

When true, earlier objects in the group are knocked out (replaced) by later objects, rather than composited on top. Default: false.
