Renderings: 

 Some friends may exist, no additional text watermark effect problem, it may be pictures of width and height have a problem, need to adjust the code of x, y coordinates.

Note: the upper left corner of the picture for the origin of the coordinate (0,0) such as testing two characters coordinates (3196, 150)

My artwork is 4090 * 2160
