Class DngImage
Nom dels espais: Aspose.Imaging.FileFormats.Dng Assemblea: Aspose.Imaging.dll (25.4.0)
L’API per al processament del format d’imatge DNG (Digital Negative) utilitzat per a digitalLes necessitats fotogràfiques proporcionen suport integral per a fitxers i metadades.Dissenyat per a ús amb càmeres digitals a través de diversos fabricants, permetdesenvolupadors per manipular aspectes com bits per píxel, extraure dades internes,i ajustar l’equilibri d’imatge eficientment. amb capacitats per actualitzar i salvar la imatgeAquesta API permet als desenvolupadors treballar amb els arxius DNG.Garantir resultats d’alta qualitat i opcions de processament versàtils.
