/**
* Loads an image from a file.
*
* imread
*
* 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 REF: IMREAD_LOAD_GDAL to load the image,
* then the [GDAL](http://www.gdal.org) driver will be used in order to decode the image, supporting
* the following formats: [Raster](http://www.gdal.org/formats_list.html),
* [Vector](http://www.gdal.org/ogr_formats.html).
*
* -
* 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 REF: IMREAD_IGNORE_ORIENTATION
* or REF: 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
*
*
*
* param filename Name of file to be loaded.
