Members

Member	Description
Enhance	Lossy compression. This option cleans up the image, removes its border if it exists and compresses it at a smaller file size than RemoveBorder.
Lossless	Lossless compression. This option compresses a 1-bit file and maintains image data unchanged. Highest quality.
LosslessFast	Faster lossless compression than Lossless. This option compresses a 1-bit file and maintains image data unchanged. Highest quality. Does not produce compression ratios as high as Lossless.
LossyFast	Lossy compression. This is the fastest ABC lossy compression option. Does not produce compression ratios as high as the other lossy options.
Modified1	Lossy compression. This option cleans up the image, removes its border if it exists and compresses it at a smaller file size than Enhance. However, it may distort some text or straight lines.
Modified1Fast	Same as Modified1 without the border remove or image clean processes.
Modified2	Lossy compression. This option cleans up the image, removes its border if it exists and compresses it at a smaller file size than Modified1. However, it may distort some text or straight lines. Maximum compression.
Modified2Fast	Lossy compression. This option compresses the image at a smaller file size than Modified1. However, it may distort some text or straight lines. Maximum compression.
Modified3	Lossy compression. Provides faster encode and decode speed than Modified1 or Modified2. if one exists and compresses it at a smaller file size than Modified1 or Modified2. Provides the maximum compression.
Modified3Fast	Same as Modified3 without the border remove or image clean processes.
RemoveBorder	Lossy compression. This option removes image border if it exists and compresses it at a smaller file size than VirtualLossless.
VirtualLossless	Lossy compression. This option removes image noisy pixels and compresses it at a smaller file size than Lossless.
