Description of how a string slice should be rendered as a text mesh.

Fields

text: &'a str

Text to render

size: f32

Font size used by the resulting mesh

raster_size: Option<f32>

Font size used for glyph rasterization; when None, TextRef::size will be used

line_height: Option<f32>

Line height scaling used by the resulting mesh

padding: Vec2

Padding used by the resuling mesh

color: Srgba

Font color used by the resulting mesh

shadow: Option<(Srgba, Vec2)>

Shadow color and offset user by the resulting mesh

character_color: Option<&'a dyn Fn(usize, usize, char) -> Srgba>

Function to generate per-character colors

align: TextAlign

Alignment used by the resulting mesh.

position: TextPosition

Position used by the resulting; see TextAlign for how this is computed

transform: Mat4

Transform used by the resulting mesh

character_transform: Option<&'a dyn Fn(usize, usize, char) -> (Mat4, Mat4)>

Function to generate per-character position and vertex transforms

Implementations

impl<'a> TextRef<'a>

pub fn new(text: &'a str) -> Self

Creates a new text description for the given string slice.

pub fn size(self, size: f32) -> Self

Specifies the font size used by the resulting mesh.

pub fn raster_size(self, raster_size: f32) -> Self

Specifies the font size used for glyph rasterization; when None, TextRef::size will be used.

pub fn line_height(self, line_height: f32) -> Self

Specifies the line height scaling used by the resulting mesh.

pub fn padding(self, padding: Vec2) -> Self

Specifies the padding used by the resulting mesh.

pub fn color(self, color: Srgba) -> Self

Specifies the font color used by the resulting mesh.

pub fn shadow(self, color: Srgba, offset: Vec2) -> Self

Specifies the shadow color and offset user by the resulting mesh.

pub fn character_color( self, color: &'a dyn Fn(usize, usize, char) -> Srgba, ) -> Self

Specifies the function to generate per-character colors.

These colors do overide the color set by TextRef::color.

pub fn align(self, align: TextAlign) -> Self

Specifies the alignment used by the resulting mesh.

pub fn position(self, position: TextPosition) -> Self

Specifies the position used by the resulting; see TextAlign for how this is computed.

pub fn transform(self, transform: Mat4) -> Self

Specifies the transform used by the resulting mesh.

pub fn character_transform( self, transform: &'a dyn Fn(usize, usize, char) -> (Mat4, Mat4), ) -> Self

Specifies the function to generate per-character position and vertex transforms

Trait Implementations

impl<'a> Default for TextRef<'a>

fn default() -> Self

Returns the “default value” for a type.
