Class DngImage
Nome do espaço: Aspose.Imaging.FileFormats.Dng Assembleia: Aspose.Imaging.dll (25.4.0)
A API para processar o formato de arquivo de imagem DNG (Digital Negative) usado para o digitalnecessidades de fotografia, proporcionando suporte abrangente para arquivos crus e metadados.Projetado para uso com câmeras digitais em vários fabricantes, permiteDesenvolvedores para manipular aspectos como bits por pixel, extrair dados internos,e ajustar o equilíbrio da imagem de forma eficiente. com a capacidade de atualizar e salvar a imagemsem dados, esta API permite que os desenvolvedores trabalhem com arquivos DNG,Garantir resultados de alta qualidade e opções de processamento versáteis.
