Interface DocumentLanguage

The aggregate language signal of a document from GigaPdfDoc.documentLanguage: its dominant reading direction, writing system, and a best-effort ISO-639-1 language code ("ar", "he", "zh"/"ja"…), undefined when the script does not pin a single language (e.g. plain Latin).

interface DocumentLanguage {
    direction: "ltr" | "rtl" | "neutral";
    script: string;
    lang?: string;
}
