ImageGear24.Twain Assembly > ImageGear.TWAIN Namespace : ImGearJPEGQuality Enumeration
This enumeration specifies the kind of JPEG quantization tables that tradeoff quality versus compressed image size.

HIGHWrite-only; implies high quality; the images display the maximum quality that produces any kind of meaningful compression. Note that images at this setting are still considered to be lossy.
LOWWrite-only; implies low quality; the images are at the maximum compression recommended by the Source.
MEDIUMWrite-only; implies medium quality; the images are at the balance point between good compression and good images. This is an arbitrary setting on the part of the Source writer that is expected to best represent their device. This is the value that Applications are most encouraged to use.
UNKNOWNRead-only; must be the setting for this capability if the user sets the JPEG compression tables using DAT_JPEGCOMPRESSION, and the Source is not able to map theselected tables to a specific percentage of quality.
ImGearCapabilities.ICAP_JPEGQUALITY capability values.
