◆ imread() [1/4]

static Mat OpenCVForUnity.ImgcodecsModule.Imgcodecs.imread ( string  filename,
int  flags 
)
static

Loads an image from a file.

The function imread loads an image from the specified file and returns it. If the image cannot be read (because of missing file, improper permissions, unsupported or invalid format), the function returns an empty matrix ( Mat::data==NULL ).

Currently, the following file formats are supported:

  • Windows bitmaps - *.bmp, *.dib (always supported)
  • JPEG files - *.jpeg, *.jpg, *.jpe (see the Note section)
  • JPEG 2000 files - *.jp2 (see the Note section)
  • Portable Network Graphics - *.png (see the Note section)
  • WebP - *.webp (see the Note section)
  • AVIF - *.avif (see the Note section)
  • Portable image format - *.pbm, *.pgm, *.ppm *.pxm, *.pnm (always supported)
  • PFM files - *.pfm (see the Note section)
  • Sun rasters - *.sr, *.ras (always supported)
  • TIFF files - *.tiff, *.tif (see the Note section)
  • OpenEXR Image files - *.exr (see the Note section)
  • Radiance HDR - *.hdr, *.pic (always supported)
  • Raster and Vector geospatial data supported by GDAL (see the Note section)
Note
  • The function determines the type of an image by the content, not by the file extension.
  • In the case of color images, the decoded images will have the channels stored in B G R order.
  • When using IMREAD_GRAYSCALE, the codec's internal grayscale conversion will be used, if available. Results may differ to the output of cvtColor()
  • On Microsoft Windows* OS and MacOSX*, the codecs shipped with an OpenCV image (libjpeg, libpng, libtiff, and libjasper) are used by default. So, OpenCV can always read JPEGs, PNGs, and TIFFs. On MacOSX, there is also an option to use native MacOSX image readers. But beware that currently these native image loaders give images with different pixel values because of the color management embedded into MacOSX.
  • On Linux*, BSD flavors and other Unix-like open-source operating systems, OpenCV looks for codecs supplied with an OS image. Install the relevant packages (do not forget the development files, for example, "libjpeg-dev", in Debian* and Ubuntu*) to get the codec support or turn on the OPENCV_BUILD_3RDPARTY_LIBS flag in CMake.
  • In the case you set WITH_GDAL flag to true in CMake and IMREAD_LOAD_GDAL to load the image, then the GDAL driver will be used in order to decode the image, supporting the following formats: Raster, Vector.
  • If EXIF information is embedded in the image file, the EXIF orientation will be taken into account and thus the image will be rotated accordingly except if the flags IMREAD_IGNORE_ORIENTATION or IMREAD_UNCHANGED are passed.
  • Use the IMREAD_UNCHANGED flag to keep the floating point values from PFM image.
  • By default number of pixels must be less than 2^30. Limit can be set using system variable OPENCV_IO_MAX_IMAGE_PIXELS
Parameters
filenameName of file to be loaded.
flagsFlag that can take values of cv::ImreadModes

◆ imwrite() [1/2]

static bool OpenCVForUnity.ImgcodecsModule.Imgcodecs.imwrite ( string  filename,
Mat  img,
MatOfInt  _params 
)
static

Saves an image to a specified file.

The function imwrite saves the image to the specified file. The image format is chosen based on the filename extension (see cv::imread for the list of extensions). In general, only 8-bit unsigned (CV_8U) single-channel or 3-channel (with 'BGR' channel order) images can be saved using this function, with these exceptions:

  • With OpenEXR encoder, only 32-bit float (CV_32F) images can be saved.
    • 8-bit unsigned (CV_8U) images are not supported.
  • With Radiance HDR encoder, non 64-bit float (CV_64F) images can be saved.
    • All images will be converted to 32-bit float (CV_32F).
  • With JPEG 2000 encoder, 8-bit unsigned (CV_8U) and 16-bit unsigned (CV_16U) images can be saved.
  • With PAM encoder, 8-bit unsigned (CV_8U) and 16-bit unsigned (CV_16U) images can be saved.
  • With PNG encoder, 8-bit unsigned (CV_8U) and 16-bit unsigned (CV_16U) images can be saved.
    • PNG images with an alpha channel can be saved using this function. To do this, create 8-bit (or 16-bit) 4-channel image BGRA, where the alpha channel goes last. Fully transparent pixels should have alpha set to 0, fully opaque pixels should have alpha set to 255/65535 (see the code sample below).
  • With PGM/PPM encoder, 8-bit unsigned (CV_8U) and 16-bit unsigned (CV_16U) images can be saved.
  • With TIFF encoder, 8-bit unsigned (CV_8U), 16-bit unsigned (CV_16U), 32-bit float (CV_32F) and 64-bit float (CV_64F) images can be saved.
    • Multiple images (vector of Mat) can be saved in TIFF format (see the code sample below).
    • 32-bit float 3-channel (CV_32FC3) TIFF images will be saved using the LogLuv high dynamic range encoding (4 bytes per pixel)

If the image format is not supported, the image will be converted to 8-bit unsigned (CV_8U) and saved that way.

If the format, depth or channel order is different, use Mat::convertTo and cv::cvtColor to convert it before saving. Or, use the universal FileStorage I/O functions to save the image to XML or YAML format.

The sample below shows how to create a BGRA image, how to set custom compression parameters and save it to a PNG file. It also demonstrates how to save multiple images in a TIFF file:

Parameters
filenameName of the file.
img(Mat or vector of Mat) Image or Images to be saved.
paramsFormat-specific parameters encoded as pairs (paramId_1, paramValue_1, paramId_2, paramValue_2, ... .) see cv::ImwriteFlags

◆ imwrite() [2/2]

static bool OpenCVForUnity.ImgcodecsModule.Imgcodecs.imwrite ( string  filename,
Mat  img 
)
static

Saves an image to a specified file.

The function imwrite saves the image to the specified file. The image format is chosen based on the filename extension (see cv::imread for the list of extensions). In general, only 8-bit unsigned (CV_8U) single-channel or 3-channel (with 'BGR' channel order) images can be saved using this function, with these exceptions:

  • With OpenEXR encoder, only 32-bit float (CV_32F) images can be saved.
    • 8-bit unsigned (CV_8U) images are not supported.
  • With Radiance HDR encoder, non 64-bit float (CV_64F) images can be saved.
    • All images will be converted to 32-bit float (CV_32F).
  • With JPEG 2000 encoder, 8-bit unsigned (CV_8U) and 16-bit unsigned (CV_16U) images can be saved.
  • With PAM encoder, 8-bit unsigned (CV_8U) and 16-bit unsigned (CV_16U) images can be saved.
  • With PNG encoder, 8-bit unsigned (CV_8U) and 16-bit unsigned (CV_16U) images can be saved.
    • PNG images with an alpha channel can be saved using this function. To do this, create 8-bit (or 16-bit) 4-channel image BGRA, where the alpha channel goes last. Fully transparent pixels should have alpha set to 0, fully opaque pixels should have alpha set to 255/65535 (see the code sample below).
  • With PGM/PPM encoder, 8-bit unsigned (CV_8U) and 16-bit unsigned (CV_16U) images can be saved.
  • With TIFF encoder, 8-bit unsigned (CV_8U), 16-bit unsigned (CV_16U), 32-bit float (CV_32F) and 64-bit float (CV_64F) images can be saved.
    • Multiple images (vector of Mat) can be saved in TIFF format (see the code sample below).
    • 32-bit float 3-channel (CV_32FC3) TIFF images will be saved using the LogLuv high dynamic range encoding (4 bytes per pixel)

If the image format is not supported, the image will be converted to 8-bit unsigned (CV_8U) and saved that way.

If the format, depth or channel order is different, use Mat::convertTo and cv::cvtColor to convert it before saving. Or, use the universal FileStorage I/O functions to save the image to XML or YAML format.

The sample below shows how to create a BGRA image, how to set custom compression parameters and save it to a PNG file. It also demonstrates how to save multiple images in a TIFF file:

Parameters
filenameName of the file.
img(Mat or vector of Mat) Image or Images to be saved.
paramsFormat-specific parameters encoded as pairs (paramId_1, paramValue_1, paramId_2, paramValue_2, ... .) see cv::ImwriteFlags
