Interface: TransparencyGroup

PDF transparency-group attributes carried on a Form XObject's /Group dictionary.

These are properties of the form definition, not of any particular invocation: every Do of a transparency-group form composites the same way.

Properties

Property	Description
`isolated` `boolean`	PDF `/Group /I` — isolated groups composite against a fully-transparent backdrop instead of inheriting the parent's.
`knockout` `boolean`	PDF `/Group /K` — knockout groups composite each child directly against the group's backdrop instead of accumulating.
`blendColorSpace` `ColorSpaceRef` \| `null`	PDF `/Group /CS` — color space used for blending inside this group. `None` falls back to the parent's blending space.
