Implementations

impl ShapingParams

pub fn validate(&self) -> Result<(), ShapingError>

Validate shaping parameters against security limits

Returns an error if:

• Font size is not finite (NaN, +/-inf)
• Font size exceeds MAX_FONT_SIZE (currently 100,000 pixels)
• Font size is negative or zero

Example

use typf_core::ShapingParams;

let params = ShapingParams { size: 48.0, ..Default::default() };
params.validate().expect("valid params");

let bad_params = ShapingParams { size: 200_000.0, ..Default::default() };
assert!(bad_params.validate().is_err());
