Imwrite flags

Variants

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

Enable JPEG features, 0 or 1, default is False.

IMWRITE_JPEG_OPTIMIZE

Enable JPEG features, 0 or 1, default is False.

IMWRITE_JPEG_RST_INTERVAL

JPEG restart interval, 0 - 65535, default is 0 - no restart.

IMWRITE_JPEG_LUMA_QUALITY

Separate luma quality level, 0 - 100, default is 0 - don't use.

IMWRITE_JPEG_CHROMA_QUALITY

Separate chroma quality level, 0 - 100, default is 0 - don't use.

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

One of cv::ImwritePNGFlags, default is IMWRITE_PNG_STRATEGY_RLE.

IMWRITE_PNG_BILEVEL

Binary level PNG, 0 or 1, default is 0.

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

override EXR storage type (FLOAT (FP32) is default)

IMWRITE_WEBP_QUALITY

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

For PAM, sets the TUPLETYPE field to the corresponding string value that is defined for the format

IMWRITE_TIFF_RESUNIT

For TIFF, use to specify which DPI resolution unit to set; see libtiff documentation for valid values

IMWRITE_TIFF_XDPI

For TIFF, use to specify the X direction DPI

IMWRITE_TIFF_YDPI

For TIFF, use to specify the Y direction DPI

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.

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.
