How to generate a beautified art QR code?

Piglet Page"s beautified art QR code, such as the ninth workshop, is very beautiful and creative.

what I know so far is that there are many QR code generation libraries, such as php, phpqrcode,js and QRCode.js.
however, it seems that ordinary QR codes are generated and cannot be beautified.

logically, I guess, it is to replace the grid in the QR code with small flowers and small dinosaurs.
knows nothing about how to implement it.

do you know anything?

I've heard of some of your requirements. The QR code is 0 and 1 in a square, the white one is 0 and the black one is 1 to express the entire 01001001011101 binary, and then shoot through the camera, and then the light sensor chip inputs the storage device. The program extracts the whole picture for color difference comparison, and the dark one is 0 in light color, that is to say, as long as the QR code can express a large contrast between light and dark, it can be recognized

.

that is to say, most of the good-looking QR codes you see on the market are generated by the artist ps, and of course, a lot of program replacement is generated, but they are all core technologies, because this contrast data needs to be tested repeatedly, and then stored as a template, and when the next user generates, directly call the template to complete the replacement.

for example, there is a sentence

on this website you posted.

so you want to generate directly to accomplish two goals. First, you have templates, and second, you have algorithms for fetching templates and replacing them.
obviously, you have nothing.
Let's look at an open source project
