Struct Code

pub struct Code {
    pub corners: [Point; 4],
    pub size: i32,
    pub cell_bitmap: [u8; 3917],
}

This structure is used to return information about detected QR codes in the input image.

Fields

corners: [Point; 4]

The four corners of the QR-code, from top left, clockwise

size: i32

The number of cells across in the QR-code. The cell bitmap is a bitmask giving the actual values of cells. If the cell at (x, y) is black, then the following bit is set:

    cell_bitmap[i >> 3] & (1 << (i & 7))

where i = (y * size) + x.

cell_bitmap: [u8; 3917]

Implementations
