Hur man konverterar bild till byte, få bildbredd och höjd med hjälp av Java



Detta är att konvertera alla bilder till byte format. Du kan konvertera jpg- eller png-format till byteformat och spara till databasen om det behövs med Java. Detta skript ger också bildegenskaper som den faktiska bildbredden och höjden i pixlar. Yuu kan få bildegenskaper med formatet "bredd x höjd" i ett strängformat.
