Tambahkan Anotasi Lampiran File Dari Stream

Anotasi lampiran file memungkinkan penyematan file sebagai ikon interaktif dalam halaman PDF. Dengan menggunakan pendekatan berbasis stream, Anda dapat melampirkan file secara dinamis tanpa bergantung pada jalur file fisik. Metode ini juga mendukung penyesuaian tampilan anotasi, termasuk opacity.

1. Buat objek PdfContentEditor.
2. Gabungkan PDF input.
3. Baca File Lampiran sebagai Stream.
4. Tambahkan Anotasi Lampiran File.
5. Simpan Document yang diperbarui.
