When we using PyQt5 tool to design the program graphical interface, sometimes maybe we want to hide the title bar to make our interface beauty:
Recently, because I have been studying the interface of the program, I got many strange problems.
I want to record today is how to merge two pictures. I found that if I simply use the composite() function in PIL, the second picture will be overwritten by the first picture. So, I started to try convert the background of the second picture to transparent.
After converting the image to a transparent background, the result of the merging is quite natural to me.
I will start to introduce how to merge two pictures in below.

Recently, the GUI I’m developing is often in a state of cessation. I think maybe I need “QThread” to help me. But when I learning how to use QThread, I was surprised to find one thing.
The tutorial in internet, it show me the LCD component is very slow, I need to use QThread to solve it ……
