SoConverterParametersSetCompressionLevel Method |
Set compression level.
Namespace: OIV.LDM.Converters
Like the -l command line argument. See also OIV.LDM.Converters.SoConverterParameters.SetCompressionName(System.String). The meaning of this parameter depends on the type of compression used:
gzip Level must be between 0 and 9: 0 gives no compression, 9 gives best compression but slower speed. Default is 3.
jpeg: Level must be between 0 and 100: 0 gives best compression but most loss of data, 100 gives minimum compression and minimum data alteration. Default is 85.
jp3d: A level of 0 specifies the lossless mode, and any other value sets the target PSNR (Peak Signal to Noise Ratio). Typical values for PSNR are: 70dB for near lossless mode, and 40dB for visually lossless mode.
