noChromaDiscrimFlag bool noChromaDiscrimFlag;: Disables CbCr discrimination - only intended for testing. If true, the Y quantization table is also used for the CbCr channels.
quality int quality;: Quality: 1-100, higher is better. Typical values are around 50-95.
subsampling JpegSubsampling subsampling;: subsampling: 0 = Y (grayscale) only 1 = YCbCr, no subsampling (H1V1, YCbCr 1x1x1, 3 blocks per MCU) 2 = YCbCr, H2V1 subsampling (YCbCr 2x1x1, 4 blocks per MCU) 3 = YCbCr, H2V2 subsampling (YCbCr 4x1x1, 6 blocks per MCU-- very common)
twoPass bool twoPass;
