Solves the challenge of rendering high-quality text by building and sampling GPU-friendly SDF, MSDF, and PSDF glyph atlases, enabling crisp, scalable text across sizes.
Use sdf-text to build and sample the atlas pipeline for rendering text in the canvas.

MSDF (multi-channel signed distance field) glyph atlases encode distance data in RGB channels to preserve sharp corners. Single-channel SDF atlases are simpler but can blur angular features, while PSDF provides optimized rendering for specific pipeline needs.
Crisp text rendering depends on integration with SDF, MSDF, or PSDF atlas types, SdfPenSnap, and SdfTextOptions definitions. You also need the associated shader and layout utilities to correctly sample and display the atlas textures.
SDF atlases use a single channel for distance data, while MSDF uses multiple channels to better preserve sharp corners. PSDF provides another variant for specific rendering pipeline needs, all building GPU-friendly textures for scalable text.
Yes, sdf-text applies directly to the core canvas text pipeline. It provides atlas construction, shader-based sampling via SkSL, and shared text-layout helpers to render scalable fonts within the canvas environment.
