Description

I have following code in my java program

final String IMAGE_PATH = "c:\\test\\250dpi.jpg";
byte imageBytes[] = readImageBytes(IMAGE_PATH);

final ImageInfo imageInfo = Sanselan.getImageInfo(imageBytes);
final int physicalWidthDpi = imageInfo.getPhysicalWidthDpi();
final int physicalHeightDpi = imageInfo.getPhysicalHeightDpi();

System.out.println("physicalWidthDpi:"+physicalWidthDpi);
