Struct quicksilver::graphics::ImmiRender

pub struct ImmiRender<'a> { /* fields omitted */ }

The implementation of the Immi rendering code for Quicksilver

This allows Immi to draw the UI to an arbitrary mesh. Used with create_immi_ctx

Methods

impl<'a> ImmiRender<'a>

pub fn new(target: &'a mut Mesh, font: &'a Font) -> ImmiRender<'a>

Deprecated since 0.3.3:

please use new_with_view instead

Create an instance of the renderer, which should be done every frame

The renderer is a short-lived object that should not be stored

pub fn new_with_view(
    target: &'a mut Mesh,
    view: View,
    font: &'a Font
) -> ImmiRender<'a>

Create a new instance of the renderer with the given view

pub fn new_with_window(window: &'a mut Window, font: &'a Font) -> ImmiRender<'a>

Create a renderer from a Window

Trait Implementations

impl<'a> Draw for ImmiRender<'a>

type ImageResource = Image

Type of a resource that represents an image.

type TextStyle = FontStyle

Type of a resource that represents the style of a text: its font, color, etc.

fn draw_triangle(
    &mut self,
    texture: &Image,
    matrix: &Matrix,
    uv_coords: [[f32; 2]; 3]
)

Draws a single triangle that covers the top-left hand corner of the surface, pre-multiplied by the matrix.

fn get_image_width_per_height(&mut self, image: &Image) -> f32

Given an image, this functions returns its width divided by its height.

fn draw_glyph(&mut self, text_style: &FontStyle, glyph: char, matrix: &Matrix)

Does the same as draw_image, but draws a glyph of a text instead.

fn line_height(&self, _text_style: &FontStyle) -> f32

Returns the height of a line of text in EMs.

fn glyph_infos(&self, text_style: &FontStyle, glyph: char) -> GlyphInfos

Returns information about a specific glyph.

fn kerning(
    &self,
    text_style: &FontStyle,
    first_char: char,
    second_char: char
) -> f32

Returns the kerning between two characters for the given font.

fn draw_image(&mut self, name: &Self::ImageResource, matrix: &Matrix)

Draws an image that covers the whole surface (from -1.0 to 1.0 both horizontally and vertically), but multiplied by the matrix.

fn draw_image_uv(
    &mut self,
    name: &Self::ImageResource,
    matrix: &Matrix,
    top_left: [f32; 2],
    top_right: [f32; 2],
    bottom_right: [f32; 2],
    bottom_left: [f32; 2]
)

Draws an image that covers the whole surface (from -1.0 to 1.0 both horizontally and vertically), but multiplied by the matrix.
