I try to use the list add x to the list, but the output is [matrix ([[0.37160519]]), matrix ([[0.37160091]]), matrix ([[0.37159685]]), matrix ([[0.371593]]), matrix ([[0.37158934]]), matrix ([[0.37158587]]), matrix ([[0.37158256]]), matrix ([[0.3715794]]), matrix ([[0.37157639]]), matrix ([[0.37157351]]), matrix ([[0.37157076]]), matrix ([[0.37156813]]), matrix ([[0.37156561]]), matrix ([[0.37156319]]), matrix ([[0.37156086]]), matrix ([[0.37155863]]]], how to get onto the x in the picture? Thank you

First you need to find a can be a bitmap graphics library operation, and then write the color value of each pixel in lattice way
