API Сканирование
API-сканирование преобразует PDF-документы в реалистичные отсканированные копии с помощью вызовов API для автоматизации и интеграции с приложениями. PDF-файлы загружаются для удалённой обработки, поэтому для этого процесса требуется интернет. Настройте цвет, шум, размытие, рамку и поворот и используйте API из любой среды разработки или языка программирования, поддерживающих отправку HTTP-запросов.
