Threshold function used for creating alpha masks for images.

const vector<FImagePtr> vector of images
const int threshold all pixels above this thresshold are set to 255, others to 0
const uint16_t flags flags for setting the behavior possible values are: THRESHOLD_DONTCARE – applies only simple threshold ONE_UNMASKED – if pixel should be black in all images after applying threshold leave it in one image (where the pixel value is highest) white, default
