Save the drawing path into the object, and then write an algorithm to judge the two objects
Oops, this is complicated, I don’t understand. Let me guess, convert the image into valid data. For example, when you draw, look at the functions you called from the background, determine how the structure of your graphics is structured, and then divide your drawing into areas, such as the center The cross dividing line takes the pixel ratio of four areas to determine the symmetry of the drawn figure. First determine whether the figure you draw is symmetrical, and if so, what kind of symmetry it is. What is the angle of symmetry, etc., to determine the status of your graphics, it is determined by a series of segmentation and comparison calculations like this. (The above are my guesses for reference only)
