OpenType Features
For fonts that include OpenType features, FlashFX exposes them in the Typography section:
| Feature | Description |
|---|---|
| Ligatures | Combines specific letter pairs into single glyphs (fi, fl, ff, ffi, ffl) |
| Contextual Alternates | Substitutes alternate glyphs based on surrounding characters |
| Stylistic Alternates | Switches to an alternative glyph design for specific characters |
| Swash | Decorative flourishes on selected characters (typically for display fonts) |
| Ordinals | Automatically raises and sizes ordinal suffixes (1st, 2nd, 3rd) |
| Fractions | Converts manually typed fractions (1/2, 3/4) to designed fraction glyphs |
| Tabular Figures | Forces all digits to use equal width (important for aligning numbers in columns) |
| Oldstyle Figures | Uses figures that descend below the baseline (0-9 with varying heights) |
| Lining Figures | Uses figures that sit on the baseline at cap height |
| Proportional Figures | Figures with widths based on their natural shape (default in most body text fonts) |
Text Rendering
Antialiasing Mode:
- -Default — browser-managed antialiasing
- -Crisp — optimized for screen legibility at small sizes; reduces blurring at pixel boundaries
- -Smooth — maximum smoothness, best for large display type
- -Geometric Precision — disables browser kerning hinting for consistent cross-browser rendering
Subpixel Rendering: On high-DPI displays, enables subpixel color channel antialiasing for sharper text at small sizes (browser-dependent support).
