public enum ImwriteFlags

Fields

ExrType = 48

[48] override EXR storage type (FLOAT (FP32) is default)

Jpeg2000CompressionX1000 = 272

For JPEG2000, use to specify the target compression rate (multiplied by 1000). The value can be from 0 to 1000. Default is 1000.

JpegChromaQuality = 6

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

JpegLumaQuality = 5

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

JpegOptimize = 3

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

JpegProgressive = 2

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

JpegQuality = 1

For JPEG, it can be a quality from 0 to 100 (the higher is the better). Default value is 95.

JpegRstInterval = 4

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

PamTupleType = 128

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

PngBilevel = 18

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

PngCompression = 16

For PNG, it can be the compression level from 0 to 9. A higher value means a smaller size and longer compression time. Default value is 3.

PngStrategy = 17

One of cv::ImwritePNGFlags, default is IMWRITE_PNG_StrategyDEFAULT.

PxmBinary = 32

For PPM, PGM, or PBM, it can be a binary format flag, 0 or 1. Default value is 1.

TiffCompression = 259

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.

TiffResUnit = 256

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

TiffXDpi = 257

For TIFF, use to specify the X direction DPI

TiffYDpi = 258

For TIFF, use to specify the Y direction DPI

WebPQuality = 64

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.
