5. Working with PhotoLine / 5.7 Creating Images For The Web
Options/File/JPEG controls the way JPEG files will be saved.
The switch Progressive JPEG causes PhotoLine to save JPEG files in a way, that allows web browsers to display the file quickly in a coarse way, enhancing it stepwise. But this option is also more memory consuming and some image processing applications have problems reading them.
JPEG-Compression controls the reduction of the resulting file size. The higher the value the better will be the image quality, but the larger will be the file size.
