Struct GsvText 

pub struct GsvText { /* private fields */ }

Geometric stroke vector text renderer.

Renders text using a built-in stroke-based font. Each character is described as a series of stroked line segments, making the output resolution-independent.

Port of C++ gsv_text.

Implementations

impl GsvText

pub fn new() -> Self

pub fn set_font(&mut self, font: Option<&'static [u8]>)

Set the font data. If None, uses the loaded font (if any).

pub fn flip(&mut self, flip_y: bool)

pub fn size(&mut self, height: f64, width: f64)

pub fn space(&mut self, space: f64)

pub fn line_space(&mut self, line_space: f64)

pub fn start_point(&mut self, x: f64, y: f64)

pub fn text(&mut self, text: &str)

pub fn load_font_data(&mut self, data: &[u8])

Load font data from a byte slice (replaces C++ file-based load_font).

pub fn text_width(&mut self) -> f64

Compute the bounding width of the current text.

Trait Implementations

impl Default for GsvText

fn default() -> Self

Returns the “default value” for a type.

impl VertexSource for GsvText

fn rewind(&mut self, _path_id: u32)

Reset the vertex source to the beginning of the given path. path_id selects which sub-path to iterate (0 for the first/only path).

fn vertex(&mut self, x: &mut f64, y: &mut f64) -> u32

Return the next vertex. Writes coordinates to x and y, returns a path command. Returns PATH_CMD_STOP when iteration is complete.
