public static class ZplCaches
Process-wide caches of the rendering engine (glyph masks, per-typeface metrics, HarfBuzz shapers, compiled property getters). All caches are thread-safe and bounded; ZplCaches.Clear releases them, e.g. after many downloaded (~DU/~DY) fonts were used and dropped.
Properties
| Property | Type | Description |
|---|
static GlyphCount { get; } | int | Number of glyphs currently cached (approximate). |
static MaxGlyphs { get; set; } | int | Maximum number of rasterised glyphs kept (default 20000, roughly 20–60 MB depending on font sizes). When exceeded the glyph cache is emptied and rebuilt on demand. 0 = unlimited. Lowering the limit below the current ZplCaches.GlyphCount empties the cache at once (not only when the next glyph is added). |
Methods
| Method Signature | Returns | Description |
|---|
static # Clear() | void | Empties all engine caches. Safe to call while other threads render. |
