Поддержка BlwhResource

Поддержка BlwhResource

BlwhResource содержит данные слоя коррекции черно-белого в Adobe Photoshop. Aspose.PSD поддерживает BlwhResource в файлах PSD. Для этого API предоставляет класс BlwhResource.

В следующем фрагменте кода показано, как Aspose.PSD поддерживает BlwhResource.
