Rect

Function

Rectangular structure for image cropping and pasting. It stores the coordinates of the upper left corner and lower right corner of a rectangle (an image).

Structure Definition

struct Rect {
    Rect()
        : x0(0), y0(0), x1(0), y1(0) {};
    Rect(const uint32_t leftTopX, const uint32_t leftTopY,
         const uint32_t rightBottomX, const uint32_t rightBottomY)
        : x0(leftTopX), y0(leftTopY), x1(rightBottomX), y1(rightBottomY) {};
    Rect(const Point leftTop, const Point rightBottom)
        : x0(leftTop.x), y0(leftTop.y), x1(rightBottom.x), y1(rightBottom.y) {};

    uint32_t x0 = 0;
    uint32_t y0 = 0;
    uint32_t x1 = 0;
    uint32_t y1 = 0;
};

Parameter Description

Parameter	Description
x0, leftTopX	Horizontal coordinate of the upper left corner of the rectangle. (The upper left corner of the image is taken as the origin of coordinates.)
y0, leftTopY	Vertical coordinate of the upper left corner of the rectangle. (The upper left corner of the image is taken as the origin of coordinates.)
x1, rightBottomX	Horizontal coordinate of the lower right corner of the rectangle. (The upper left corner of the image is taken as the origin of coordinates.)
y1, rightBottomY	Vertical coordinate of the lower right corner of the rectangle. (The upper left corner of the image is taken as the origin of coordinates.)
leftTop	Coordinates of the upper left corner of the rectangle in point structure.
rightBottom	Coordinates of the lower right corner of the rectangle in point structure.
