pdf_harfbuzz

A companion package for pdf that provides HarfBuzz text shaping for complex scripts.

This package provides a HarfBuzzText widget that can be used to render text using the HarfBuzz shaping engine. This is particularly useful for rendering complex scripts like Arabic, Khmer, Thai, and Indic scripts correctly in PDF documents.

Usage

Add pdf_harfbuzz as a dependency in your pubspec.yaml file.

dependencies:
  pdf_harfbuzz: ^0.1.0

Then you can use HarfBuzzText just like you would use a regular Text widget in pdf:

import 'package:pdf/widgets.dart' as pw;
import 'package:pdf_harfbuzz/pdf_harfbuzz.dart';

// ...

pdf.addPage(
  pw.Page(
    build: (pw.Context context) {
      return pw.Center(
        child: pw.HarfBuzzText(
          'សួស្តីពិភពលោក', // Khmer for "Hello World"
          style: pw.TextStyle(
            font: khmerFont,
            fontSize: 24,
          ),
        ),
      );
    },
  ),
);
