Lossless rotation of JPEG images
• With OLYMPUS Studio, JPEG images can be rotated without having to re-
compress the JPEG image data. This is called “lossless rotation”. Because
JPEG is a irreversible compression method in which the data is degraded at
the time of compression, when a compressed image is rotated and saved,
noise characteristic to JPEG appears in the image. In a lossless rotation,
however, the JPEG image can be rotated without being recompressed.
If, however, the JPEG image data that is rotated does not have height and
width as a multiple of 8, the lossless rotation is not performed immediately.
Instead, a dialog box appears, prompting you to select the processing method.
You can select either to have the image cropped and then perform a lossless
rotation or have the image rotated normally without being cropped.
