Enumerator
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.
IMWRITE_JPEG_OPTIMIZE Python: cv.IMWRITE_JPEG_OPTIMIZE	Enable JPEG features, 0 or 1, default is False.
IMWRITE_JPEG_RST_INTERVAL Python: cv.IMWRITE_JPEG_RST_INTERVAL	JPEG restart interval, 0 - 65535, default is 0 - no restart.
IMWRITE_JPEG_LUMA_QUALITY Python: cv.IMWRITE_JPEG_LUMA_QUALITY	Separate luma quality level, 0 - 100, default is 0 - don't use.
IMWRITE_JPEG_CHROMA_QUALITY Python: cv.IMWRITE_JPEG_CHROMA_QUALITY	Separate chroma quality level, 0 - 100, default is 0 - don't use.
IMWRITE_PNG_COMPRESSION Python: cv.IMWRITE_PNG_COMPRESSION	For PNG, it can be the compression level from 0 to 9. A higher value means a smaller size and longer compression time. If specified, strategy is changed to IMWRITE_PNG_STRATEGY_DEFAULT (Z_DEFAULT_STRATEGY). Default value is 1 (best speed setting).
IMWRITE_PNG_STRATEGY Python: cv.IMWRITE_PNG_STRATEGY	One of cv::ImwritePNGFlags, default is IMWRITE_PNG_STRATEGY_RLE.
IMWRITE_PNG_BILEVEL Python: cv.IMWRITE_PNG_BILEVEL	Binary level PNG, 0 or 1, default is 0.
IMWRITE_PXM_BINARY Python: cv.IMWRITE_PXM_BINARY	For PPM, PGM, or PBM, it can be a binary format flag, 0 or 1. Default value is 1.
IMWRITE_EXR_TYPE Python: cv.IMWRITE_EXR_TYPE
IMWRITE_WEBP_QUALITY Python: cv.IMWRITE_WEBP_QUALITY	override EXR storage type (FLOAT (FP32) is default) For WEBP, it can be a quality from 1 to 100 (the higher is the better). By default (without any parameter) and for quality above 100 the lossless compression is used.
IMWRITE_PAM_TUPLETYPE Python: cv.IMWRITE_PAM_TUPLETYPE	For PAM, sets the TUPLETYPE field to the corresponding string value that is defined for the format.
IMWRITE_TIFF_RESUNIT Python: cv.IMWRITE_TIFF_RESUNIT	For TIFF, use to specify which DPI resolution unit to set; see libtiff documentation for valid values.
IMWRITE_TIFF_XDPI Python: cv.IMWRITE_TIFF_XDPI	For TIFF, use to specify the X direction DPI.
IMWRITE_TIFF_YDPI Python: cv.IMWRITE_TIFF_YDPI	For TIFF, use to specify the Y direction DPI.
IMWRITE_TIFF_COMPRESSION Python: cv.IMWRITE_TIFF_COMPRESSION	For TIFF, use to specify the image compression scheme. See libtiff for integer constants corresponding to compression formats. 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.
