@C1@c@b@_ JPEG Options
Basic parameters for JPEG compression.
@b Q(uality) value
Higher the Q value, the larger the JPEG file and closer the output
image will be to the input image. The practical value should be
between 50 and 95. The default 75 is often about right.
@b Smoothing
Smooth the input image to eliminate dithering noise. Often useful when
converting 8bit images to JPEG. A moderate smoothing factor of 10 to 50
may be used in certain situations.
@b Optimize
Produces a somewhat smaller file and runs a little slower and uses
much more memory.
@b Note
All these settings are ballpark figures. Different image may
require different settings to get the best quality/minimum file size.
Experiment!
