MemberDescription
MCMaximum compression. This option gives maximum compression. It is equivalent to a Q factor of 255.
MCQMaximum compression keeping quality. This option provides maximum compression while maintaining as high as possible image quality.
PQ1Perfect quality 1. This option compresses all colors of a 24-bit file and maintains the quality of the original image at a smaller file size. As the name suggests, there is no visual loss of color at this setting.
PQ2Perfect quality 2. This will produce a smaller file size than PQ1 while maintaining similar quality.
QFSQuality far more important than size. This option removes colors not noticed by the human eye. Most viewers cannot tell the difference between an image compressed at this level and the original image.
QMSQuality more important than size. While more colors are removed, most of them are colors or shades that are close to one another. The compressed image will appear very much like the original image. It will take some study to see the difference.
QSQuality and size equally important. This option provides the highest compression while maintaining good image quality. Try this option first, then move up or down the list accordingly to obtain acceptable compression size and image quality.
SQSSize more important that quality (sharp). This option is recommended for images that have sharp edges. For example, an image that has a text overlay or an image with many straight lines. While it creates a larger file than the next option, it retains better edges
SQTSize more important than quality (less tiling). This option produces less tiling in the image than the previous options. However, it may distort text or straight lines. It is a good option for image database applications.
Remarks
You can specify a quality factor when saving an image file to the LEAD (CMP) format, or one of the JPEG still image formats. The quality factor (Q factor) is a number that determines the acceptable degree of loss in the compression process. Values can be set from 2 to 255, where 2 is the highest quality and 255 is the most compressed.
