Theoretically CompressJpg allows you to compress every jpeg
image on your hard drive at one setting. Practically, the
multi-directory scan will allow you to compress any number of
directories, each having different compression settings as follows:
- target ratio or fixed quality
- smoothing factor
- contrast, brightness, color and hue
Use of the target ratiotm is an exclusive feature
designed to produce "same-size" images. The standard fixed quality can
produce panoramic images twice as large as closeups for the same
setting.
Either the standard fixed quality setting or the nonlinear target
ratio must be used for the entire run.
Image clipping is available in batch mode for same-size portrait and
landscape images as well.
