Implementations

impl FontCache

pub fn new() -> Self

pub fn is_loaded(&self) -> bool

pub fn loaded_from(&self) -> Option<&Path>

pub fn loaded_face_index(&self) -> u32

pub fn load_for_project(&mut self, project_dir: &Path) -> bool

pub fn load_for_project_named( &mut self, project_dir: &Path, requested_name: &str, ) -> bool

Select the effective engine font and load it if necessary.

Siglus resolves the active face in this order: local SCRIPT override, then the current SYSCOM configuration. tnm_update_font() clears the original glyph manager when that face changes. This method mirrors the same boundary and deliberately does not retain the first face forever.

pub fn requested_name(&self) -> &str

pub fn load_from_font_dir(&mut self, font_dir: &Path) -> bool

pub fn render_text( &self, images: &mut ImageManager, text: &str, font_px: f32, max_w: u32, max_h: u32, ) -> Option<ImageHandle>

pub fn render_mwnd_text( &self, images: &mut ImageManager, text: &str, font_px: f32, max_w: u32, max_h: u32, moji_space: Option<(i64, i64)>, ) -> Option<ImageHandle>

pub fn render_mwnd_text_styled( &self, images: &mut ImageManager, text: &str, font_px: f32, max_w: u32, max_h: u32, moji_space: Option<(i64, i64)>, style: TextStyle, ) -> Option<ImageHandle>

pub fn render_mwnd_text_styled_into( &self, images: &mut ImageManager, target: Option<ImageHandle>, text: &str, font_px: f32, max_w: u32, max_h: u32, moji_space: Option<(i64, i64)>, style: TextStyle, ) -> Option<ImageHandle>

pub fn render_positioned_glyphs_into( &self, images: &mut ImageManager, target: Option<ImageHandle>, glyphs: &[PositionedTextGlyph], min_w: u32, min_h: u32, ) -> Option<PositionedTextRender>

pub fn render_positioned_glyph_layer_into( &self, images: &mut ImageManager, target: Option<ImageHandle>, glyphs: &[PositionedTextGlyph], min_w: u32, min_h: u32, layer: Option<TextSpriteLayer>, ) -> Option<PositionedTextRender>

pub fn render_single_glyph_layer_into( &self, images: &mut ImageManager, target: Option<ImageHandle>, glyph: PositionedTextGlyph, layer: TextSpriteLayer, ) -> Option<PositionedTextRender>

Rasterize one glyph into a tight texture for the original shadow/fuchi/body-per-glyph sprite model. The returned offsets are relative to the requested glyph anchor and include outline/shadow padding and font bearing.

pub fn render_text_into( &self, images: &mut ImageManager, target: Option<ImageHandle>, text: &str, font_px: f32, max_w: u32, max_h: u32, ) -> Option<ImageHandle>

pub fn render_editbox_into( &self, images: &mut ImageManager, target: Option<ImageHandle>, text: &str, cursor_pos: usize, selection: Option<(usize, usize)>, composition_text: &str, composition_cursor: Option<(usize, usize)>, composition_range: Option<(usize, usize)>, scroll_x_px: i32, caret_visible: bool, font_px: f32, max_w: u32, max_h: u32, ) -> Option<ImageHandle>

pub fn render_text_rgba( &self, text: &str, font_px: f32, max_w: u32, max_h: u32, ) -> Option<RgbaImage>

pub fn text_line_metrics( &self, text: &str, font_px: f32, max_w: u32, max_h: u32, ) -> (usize, f32)

Rendered line count and line pitch of the layout Self::render_text_into would produce for the same arguments.

Text drawn as one image has no per-row rectangles, so hit-testing has to be derived from the layout. Reporting it from the renderer keeps the drawn rows and the clickable rows identical (an estimate such as “40 + lines * 30” drifts by rows as soon as the pitch or the wrapped line count differs).

pub fn render_mwnd_text_rgba( &self, text: &str, font_px: f32, max_w: u32, max_h: u32, moji_space: Option<(i64, i64)>, ) -> Option<RgbaImage>

pub fn render_mwnd_text_rgba_styled( &self, text: &str, font_px: f32, max_w: u32, max_h: u32, moji_space: Option<(i64, i64)>, style: TextStyle, ) -> Option<RgbaImage>

pub fn render_mwnd_text_layer_styled_into( &self, images: &mut ImageManager, target: Option<ImageHandle>, text: &str, font_px: f32, max_w: u32, max_h: u32, moji_space: Option<(i64, i64)>, style: TextStyle, vertical: bool, layer: TextSpriteLayer, ) -> Option<ImageHandle>
