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

    Number of channels (from 1 to (CV_CN_MAX - 1))

  • Get number of channels for type

    Declaration

    Objective-C

    + (int)channels:(int)type;

    Swift

    class func channels(_ type: Int32) -> Int32

    Parameters

    type

    Type value
