Struct emath::RectTransform

source · [−]

#[repr(C)]
pub struct RectTransform { /* private fields */ }

Expand description

Linearly transforms positions from one Rect to another.

RectTransform stores the rectangles, and therefore supports clamping and culling.

Implementations

source

pub fn scale(&self) -> Vec2

The scale factors.

source

pub fn inverse(&self) -> RectTransform

source

pub fn transform_pos(&self, pos: Pos2) -> Pos2

Transforms the given coordinate in the from space to the to space.

source

pub fn transform_rect(&self, rect: Rect) -> Rect

Transforms the given rectangle in the in-space to a rectangle in the out-space.

source

pub fn transform_pos_clamped(&self, pos: Pos2) -> Pos2

Transforms the given coordinate in the from space to the to space, clamping if necessary.
