IMWRITE_JPEG_QUALITY Python: cv.IMWRITE_JPEG_QUALITY | For JPEG, it can be a quality from 0 to 100 (the higher is the better). Default value is 95. |
IMWRITE_JPEG_PROGRESSIVE Python: cv.IMWRITE_JPEG_PROGRESSIVE | Enable JPEG features, 0 or 1, default is False. |

Note, for images whose depth is CV_32F, only libtiff's SGILOG compression scheme is used. For other supported depths, the compression scheme can be specified by this flag; LZW compression is the default. |
IMWRITE_TIFF_ROWSPERSTRIP Python: cv.IMWRITE_TIFF_ROWSPERSTRIP | For TIFF, use to specify the number of rows per strip. |
IMWRITE_TIFF_PREDICTOR Python: cv.IMWRITE_TIFF_PREDICTOR | For TIFF, use to specify predictor. See cv::ImwriteTiffPredictorFlags. |
IMWRITE_JPEG2000_COMPRESSION_X1000 Python: cv.IMWRITE_JPEG2000_COMPRESSION_X1000 | For JPEG2000, use to specify the target compression rate (multiplied by 1000). The value can be from 0 to 1000. Default is 1000. |
IMWRITE_AVIF_QUALITY Python: cv.IMWRITE_AVIF_QUALITY | For AVIF, it can be a quality between 0 and 100 (the higher the better). Default is 95. |
IMWRITE_AVIF_DEPTH Python: cv.IMWRITE_AVIF_DEPTH | For AVIF, it can be 8, 10 or 12. If >8, it is stored/read as CV_32F. Default is 8. |
IMWRITE_AVIF_SPEED Python: cv.IMWRITE_AVIF_SPEED | For AVIF, it is between 0 (slowest) and (fastest). Default is 9. |
