Members
ValueMemberDescription
0LosslessLossless compression. This option compresses a 1-bit file and maintains image data unchanged. Highest quality.
1VirtualLosslessLossy compression. This option removes image noisy pixels and compresses it at a smaller file size than Lossless.
2RemoveBorderLossy compression. This option removes image border if it exists and compresses it at a smaller file size than VirtualLossless.
3EnhanceLossy compression. This option cleans up the image, removes its border if it exists and compresses it at a smaller file size than RemoveBorder.
4Modified1Lossy 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.
5Modified1FastSame as Modified1 without the border remove or image clean processes.
6Modified2Lossy 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.
7Modified2FastLossy compression. This option compresses the image at a smaller file size than Modified1. However, it may distort some text or straight lines. Maximum compression.
8Modified3Lossy 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.
9Modified3FastSame as Modified3 without the border remove or image clean processes.
10LosslessFastFaster 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.
11LossyFastLossy compression. This is the fastest ABC lossy compression option. Does not produce compression ratios as high as the other lossy options.
