Syntax
sod_img sod_img_load_from_cv(const char *zFile, int nChannels);Description
Load an image from disk via OpenCV cvLoadImage(). The library must be compiled against OpenCV with the compile-time directive SOD_ENABLE_OPENCV defined. On success, a memory representation of the target image is returned in an instance of the sod_img object which can be processed or analyzed via the exported interfaces.
Parameters
const char *zFile
Source path of the target image to load.
int nChannels
Total number of color channels to load. Set this value to 0 for the default behavior. 1 for grayscale conversion or 3 for full color channels.
Return Value
Memory representation of the target image is returned in an instance of the sod_img object. if something goes wrong during loading (i.e. Invalid path, format or running out-of-memory), then an empty image is returned via sod_make_empty_image(). Once done, you must release the memory allocated to this object via sod_free_image() to avoid memory leaks.
Example
Checkout the introduction course, the C/C++ samples on the download page or refer to the SOD Github Repository.
