I want to know how to write a transparent window like Windows under DOS? What is the principle?

The principle should be to take the RGB values of each pixel of the window and the corresponding pixel in the background, and mix them in a certain proportion to allocate the "intermediate color". Hehe, I'm just guessing randomly.

DOS also writes these, it's too... In fact, the command line doesn't lie in beauty but in practicality

The principle of transparency is very easy. RGB(background) * background level + RGB(foreground) * foreground level. Background level + foreground level = 10.
