Struct BurnSubsConfig 

pub struct BurnSubsConfig {
    pub entries: Vec<SubtitleEntry>,
    pub default_font: SubtitleFont,
    pub frame_width: u32,
    pub frame_height: u32,
    pub shadow_enabled: bool,
    pub antialias: bool,
}

Configuration for the subtitle burn-in operation.

Fields

entries: Vec<SubtitleEntry>

All subtitle entries to burn in.

default_font: SubtitleFont

Default font for all entries without a font override.

frame_width: u32

Video frame width in pixels.

frame_height: u32

Video frame height in pixels.

shadow_enabled: bool

Whether to enable soft-shadow rendering.

antialias: bool

Whether to enable anti-aliased text rendering.

Implementations

impl BurnSubsConfig

pub fn new(frame_width: u32, frame_height: u32) -> Self

Creates a new burn-subs configuration.

pub fn add_entry(self, entry: SubtitleEntry) -> Self

Adds a subtitle entry.

pub fn with_default_font(self, font: SubtitleFont) -> Self

Sets the default font.

pub fn active_at(&self, timestamp_ms: u64) -> Vec<&SubtitleEntry>

Returns all entries active at the given timestamp.

pub fn compute_position( &self, entry: &SubtitleEntry, text_width: u32, text_height: u32, ) -> (u32, u32)

Computes the pixel position for an entry based on its anchor.

pub fn estimate_text_size(&self, text: &str, font: &SubtitleFont) -> (u32, u32)

Mock font rasterization: returns estimated text dimensions.

In a real implementation this would call a font rendering library.

pub fn validate(&self) -> Vec<String>

Validates all subtitle entries.

Returns a list of validation errors (empty if valid).
