Preprocessor Macro around sod_img_load_from_file() for grayscale colorspace conversion during image loading.
Source path of the target image to load.
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.
