Enum TextAlign 

pub enum TextAlign {
    ScreenAbsolute(i32, i32),
    ScreenRelative(i32, i32),
    Viewport(i32, i32),
    Scene(Vec3, i32, i32),
}

Specifies how the position property of a TextRef is applied.

Variants

ScreenAbsolute(i32, i32)

Positions the text relative to the bottom left corner of the screen, then anchors it with respect to its bounding box.

Examples

• TextAlign::Screen(0, 0): Anchors at the center
• TextAlign::Screen(1, -1): Anchors at the upper left corner

ScreenRelative(i32, i32)

Positions the text relative to the center of the screen, then anchors it with respect to its bounding box.

Examples

• TextAlign::Screen(0, 0): Anchors at the center
• TextAlign::Screen(1, -1): Anchors at the upper left corner

Viewport(i32, i32)

Anchors the text to the edges of the viewport (as set by TextBuilder::set_viewport), then positions it with respect to its bounding box.

Examples

• TextAlign::Viewport(0, 0): Anchors at the lower left corner of the viewport
• TextAlign::Viewport(1, 0): Anchors at the right edge of the viewport

Scene(Vec3, i32, i32)

Anchors the text to the projected position of the 3D point (as described by TextBuilder::set_projection_view), then positions it with respect to its bounding box.

Examples

• TextAlign::Scene(vec(0.0, 0.0, 0.0), 0, 0): Projects the scene’s origin then anchors at the center

Implementations

impl TextAlign

pub fn into_global_and_local_offset( self, world_to_screen: Mat4, viewport: Vec2, bounds: Vec2, ) -> Option<(Vec2, Vec2)>

Calculates the global and local offets required to align a rectangle with the given bounds inside the specified viewport.

Important: This assumes that the rectangle’s lower left corner is at the coordinates 0, 0.
