The format type IDs for cv::imwrite and cv::inencode
Namespace: OpenCvSharp
Assembly: OpenCvSharp.dll
Syntax
public enum ImwriteFlagsFields
| Name | Description |
|---|---|
| ExrType | [48] override EXR storage type (FLOAT (FP32) is default) |
| Jpeg2000CompressionX1000 | For JPEG2000, use to specify the target compression rate (multiplied by 1000). The value can be from 0 to 1000. Default is 1000. |
| JpegChromaQuality | Separate chroma quality level, 0 - 100, default is 0 - don't use. |
| JpegLumaQuality | Separate luma quality level, 0 - 100, default is 0 - don't use. |
| JpegOptimize | Enable JPEG features, 0 or 1, default is False. |
| JpegProgressive | Enable JPEG features, 0 or 1, default is False. |
| JpegQuality | For JPEG, it can be a quality from 0 to 100 (the higher is the better). Default value is 95. |
| JpegRstInterval | JPEG restart interval, 0 - 65535, default is 0 - no restart. |
| PamTupleType | For PAM, sets the TUPLETYPE field to the corresponding string value that is defined for the format |
| PngBilevel | Binary level PNG, 0 or 1, default is 0. |
| PngCompression | 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 | One of cv::ImwritePNGFlags, default is IMWRITE_PNG_StrategyDEFAULT. |
| PxmBinary | For PPM, PGM, or PBM, it can be a binary format flag, 0 or 1. Default value is 1. |
| TiffCompression | 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 | For TIFF, use to specify which DPI resolution unit to set; see libtiff documentation for valid values |
| TiffXDpi | For TIFF, use to specify the X direction DPI |
| TiffYDpi | For TIFF, use to specify the Y direction DPI |
| WebPQuality | 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. |
