[0059] (1) Change the black area of the two-dimensional code image into color to generate a three-dimensional code color image;
[0060] Traverse the entire image on the black and white two-dimensional code image to obtain the size of the unit block that can form the black area of the image, define the size of the color block according to the size of the unit block, the size of the color block is an integer multiple of the size of the unit block, and convert the entire black and white two-dimensional code The image is divided according to the size of the color block. If the image size of the two-dimensional code is not an integer multiple of the color block, the remaining area is regarded as a color block, and the entire two-dimensional code image is traversed, and the black area corresponding to the same color block is randomly changed. One of the three colors of red, green, and blue (R, G, B), the white area remains unchanged, and finally a random color three-dimensional ...
