Struct Font

pub struct Font {
    pub bitmap_file: String,
    pub width: u32,
    pub height: u32,
    pub gl_id: Option<NativeTexture>,
    pub tile_size: (u32, u32),

}

BTerm’s representation of a font or tileset file.

Fields

bitmap_file: String

width: u32

height: u32

gl_id: Option<NativeTexture>

tile_size: (u32, u32)

explicit_background: Option<RGB>

font_dimensions_glyphs: (u32, u32)

Implementations

impl Font

pub fn new<S>( filename: S, width: u32, height: u32, tile_size: (u32, u32), ) -> Font

where S: ToString,

Creates an unloaded texture with filename and size parameters provided.

pub fn load<S>( filename: S, tile_size: (u32, u32), explicit_background: Option<RGB>, ) -> Font

where S: ToString,

Loads a font file (texture) to obtain the width and height for you

pub fn setup_gl_texture( &mut self, gl: &Context, ) -> Result<NativeTexture, Box<dyn Error + Send + Sync>>

Load a font, and allocate it as an OpenGL resource. Returns the OpenGL binding number (which is also set in the structure).

pub fn bind_texture(&self, gl: &Context)

Sets this font file as the active texture

Trait Implementations

impl Clone for Font

fn clone(&self) -> Font

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for Font

fn eq(&self, other: &Font) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
