MemberDescription
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.
VirtualLossless Lossy compression. This option removes image noisy pixels and compresses it at a smaller file size than Lossless.
RemoveBorder Lossy compression. This option removes image border if it exists and compresses it at a smaller file size than VirtualLossless.
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.
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. Provdes 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.
