Isso é converter qualquer imagem em formato de byte. Você pode converter o formato jpg ou png em formato de byte e salvar no banco de dados, se necessário, usando Java. Esse script também fornece propriedades de imagem, como largura e altura reais da imagem em pixels. Yuu pode obter propriedades de imagem com formato “largura x altura” em um formato de string.
