Enum MagnificationHandlerRequest

Source 
pub enum MagnificationHandlerRequest {
    SetClipSpaceTransform {
        x: f32,
        y: f32,
        scale: f32,
        responder: MagnificationHandlerSetClipSpaceTransformResponder,
    },
}
Expand description

Exposes a privileged magnifier API for camera control, typically on a fuchsia.ui.policy.Presentation.

Variants§

§

SetClipSpaceTransform

Sets clip-space x-offset, y-offset, and scale for the presentation. x and y are in Vulkan NDC and are applied after scaling, which occurs about the center of the presentation. The callback indicates when the update has been presented. The identity transform (0, 0, 1) is the natural state.
