python - 如何从源代码查看opencv方法中的枚举器？

问题描述

我想在OpenCV-python的源码中找到特定方法的关键字参数的枚举类型常量。例如，cv2 中的“插值”。resize() 在官网上点击“interpolationflags”很容易找到，但是在源码中好像找不到“interpolationflags”。

解决方案

这里

enum InterpolationFlags{
    /** nearest neighbor interpolation */
    INTER_NEAREST        = 0,
    /** bilinear interpolation */
    INTER_LINEAR         = 1,
    /** bicubic interpolation */
    INTER_CUBIC          = 2,
    /* resampling using pixel area relation. It may be a preferred method for image decimation, as it gives moire-free results. But when the image is zoomed, it is similar to the INTER_NEAREST  method. */
    INTER_AREA           = 3,
    /** Lanczos interpolation over 8x8 neighborhood */
    INTER_LANCZOS4       = 4,
    /** Bit exact bilinear interpolation */
    INTER_LINEAR_EXACT = 5,
    /** Bit exact nearest neighbor interpolation. This will produce same results as
    the nearest neighbor method in PIL, scikit-image or Matlab. */
    INTER_NEAREST_EXACT  = 6,
    /** mask for interpolation codes */
    INTER_MAX            = 7,
    /** flag, fills all of the destination image pixels. If some of them correspond to outliers in the
    source image, they are set to zero */
    WARP_FILL_OUTLIERS   = 8,
    /** flag, inverse transformation
    For example, #linearPolar or #logPolar transforms:
    - flag is __not__ set: \f$dst( \rho , \phi ) = src(x,y)\f$
    - flag is set: \f$dst(x,y) = src( \rho , \phi )\f$
    */
    WARP_INVERSE_MAP     = 16
};
