Struct gfx_text::Renderer

pub struct Renderer<R: Resources, F: Factory<R>> { /* fields omitted */ }

Text renderer.

Methods

impl<R: Resources, F: Factory<R>> Renderer<R, F>

fn add(&mut self, text: &str, pos: [i32; 2], color: [f32; 4])

Add some text to the current draw scene relative to the top left corner of the screen using pixel coordinates.

fn add_anchored(
    &mut self,
    text: &str,
    pos: [i32; 2],
    horizontal: HorizontalAnchor,
    vertical: VerticalAnchor,
    color: [f32; 4]
)

Add text to the draw scene by anchoring an edge or mid-point to a position defined in screen pixel coordinates.

fn add_at(&mut self, text: &str, pos: [f32; 3], color: [f32; 4])

Add some text to the draw scene using absolute world coordinates.

fn draw<C: CommandBuffer<R>, T: RenderFormat>(
    &mut self,
    encoder: &mut Encoder<R, C>,
    target: &RenderTargetView<R, T>
) -> Result<(), Error>

Draw the current scene and clear state.

Examples

text.add("Test1", [10, 10], [1.0, 0.0, 0.0, 1.0]);
text.add("Test2", [20, 20], [0.0, 1.0, 0.0, 1.0]);
text.draw(&mut encoder, &color_output).unwrap();

fn draw_at<C: CommandBuffer<R>, T: RenderFormat>(
    &mut self,
    encoder: &mut Encoder<R, C>,
    target: &RenderTargetView<R, T>,
    proj: [[f32; 4]; 4]
) -> Result<(), Error>

Draw using provided projection matrix.

Examples

text.add_at("Test1", [6.0, 0.0, 0.0], [1.0, 0.0, 0.0, 1.0]);
text.add_at("Test2", [0.0, 5.0, 0.0], [0.0, 1.0, 0.0, 1.0]);
text.draw_at(&mut encoder, &color_output, camera_projection).unwrap();

fn measure(&self, text: &str) -> (i32, i32)

Get the bounding box size of a string as rendered by this font.
