Crate luminance_glyph

Expand description

A fast text renderer for luminance, powered by glyph_brush.

Initially forked and modified from glow_glyph by hecrj. Many thanks to hecrj!

Modules§

Extra: Default extra field type. Non-layout data for vertex generation.
FontId: Id for a font.
GlyphBrush: Object allowing glyph drawing, containing cache state. Manages glyph positioning cacheing, glyph draw caching & efficient GPU texture cache updating and re-sizing on demand.
GlyphBrushBuilder: Builder for a GlyphBrush.
GlyphVertex: Data used to generate vertex information for a single glyph
Instance
LeftTop: Vertex attribute type (representing #repr_ty_name).
Region: A region of the screen.
RightBottom: Vertex attribute type (representing #repr_ty_name).
Section: An object that contains all the info to render a varied section of text. That is one including many parts with differing fonts/scales/colors bowing to a single layout.
SectionGeometry
SectionGlyph: A positioned glyph with info relating to the SectionText (or glyph_brush Section::text) from which it was derived.
SectionText: Text to layout together using a font & scale.
TexLeftTop: Vertex attribute type (representing #repr_ty_name).
TexRightBottom: Vertex attribute type (representing #repr_ty_name).
Text: SectionText + extra.
VertexColor: Vertex attribute type (representing #repr_ty_name).

BuiltInLineBreaker: Built-in linebreaking logic.
HorizontalAlign: Describes horizontal alignment preference for positioning & bounds.
Layout: Built-in GlyphPositioner implementations.
LineBreak: Indicator that a character is a line break, soft or hard. Includes the offset (byte-index) position.
VerticalAlign: Describes vertical alignment preference for positioning & bounds. Currently a placeholder for future functionality.

GlyphBrushBackend
GlyphCruncher: Common glyph layout logic.
GlyphPositioner: Logic to calculate glyph positioning using Font, SectionGeometry and SectionText.
LineBreaker: Producer of a LineBreak iterator. Used to allow to the Layout to be line break aware in a generic way.

orthographic_projection: Helper function to generate a generate a transform matrix.
