Utility functions for handling CvType values

Type Utility functions

  • Create CvType value from depth and channel values

    Declaration

    Objective-C

    + (int)makeType:(int)depth channels:(int)channels;

    Swift

    class func make(_ depth: Int32, channels: Int32) -> Int32

    Parameters

    depth

    Depth value. One of CV_8U, CV_8S, CV_16U, CV_16S, CV_32S, CV_32F or CV_64F
    channels
