Description

BORDER_CONSTANT: Constant colored border.
BORDER_REPLICATE: Last element replicated throughout. For example, aaaaaa|a*****h|hhhhhhh (where * indicates any image element).
BORDER_REFLECT: Reflection of border elements (included). For example, ba|abc*******fgh|hg (where * indicates any image element).
BORDER_REFLECT_101: Reflection of border elements (excluded). For example, cb|abc****fgh|gf (where * indicates any image element).

Defines the padding configuration for image processing. You can set the numbers of pixels for left, right, top, and bottom padding, padding color constants, and padding mode.

Structure Definition

    enum BorderType {
        BORDER_CONSTANT = 0,
        BORDER_REPLICATE,
        BORDER_REFLECT,
        BORDER_REFLECT_101
    };
    uint32_t left;
    uint32_t right;
    uint32_t top;
    uint32_t bottom;
    uint32_t channel_zero;
    uint32_t channel_one;
    uint32_t channel_two;
    BorderType borderType;
};

Parameters

Parameter	Input/Output	Description
left	Input	Number of pixels for left padding
right	Input	Number of pixels for right padding
top	Input	Number of pixels for top padding
bottom	Input	Number of pixels for bottom padding
channel_zero	Input	Value of channel 0. Must be in the range of [0, 255].
channel_one	Input	Value of channel 1. Must be in the range of [0, 255].
channel_two	Input	Value of channel 2. Must be in the range of [0, 255].
borderType	Input	Padding mode. BORDER_CONSTANT: Constant colored border. BORDER_REPLICATE: Last element replicated throughout. For example, aaaaaa\|a*h\|hhhhhhh (where * indicates any image element). BORDER_REFLECT: Reflection of border elements (included). For example, ba\|abc***fgh\|hg (where * indicates any image element). BORDER_REFLECT_101: Reflection of border elements (excluded). For example, cb\|abcfgh\|gf (where * indicates any image element).

channel_zero, channel_one, and channel_two correspond to the image channels. For example, when RGB is used, channel_zero corresponds to channel R, channel_one corresponds to channel G, and channel_two corresponds to channel B.
