Struct AppearanceStreamBuilder

Source

pub struct AppearanceStreamBuilder { /* private fields */ }

Expand description

Builds content stream operations for annotation appearance streams.

All coordinates are in the Form XObject’s local coordinate system, where (0,0) is the bottom-left of the annotation rectangle.
