Note that superimposing an image on a QR code is not officially recommended. It is easy to embed the image into the QR code.

Paste another image into an image with Python, Pillow.

or the #xxxxxx style.ДЇor more information about paste(), see the following articles: Specify fill_color and back_color using color names black, white, red, etc. You can set the color with the fill_color and back_color of the make_image() method. The default value is 4, which is the minimum width in the specification. The number of pixels in the margin width is box_size * border. You can use border to set the width (number of cells) of the outer margin. With box_size, you can set the size of the cell (square black and white dot) in pixels.Д®ven if version is the same (the number of cells is the same), you can change the size of the generated image by changing box_size. When generating a QR code image from string of the same length, increasing the error correction level increases the size of the generated QR code image.

_CORRECT_H (Approx 30%)ДЇor more information about the QR code error correction feature, refer to the official page of Denso Wave below.

The values in parentheses indicate error correction ability (error correction rate for all codewords). You can set the error correction level with error_correction. Note that even if you specify a smaller version, if the data does not fit, it will automatically be the minimum version that fits the data. The minimum value of version is 1, and the maximum is 40.Д«y specifying version, you can generate a QR code image larger than the optimal version (minimum size), so it is useful when you want to create multiple QR codes with different data contents with the same size.

Information capacity and versions of QR Code | | DENSO WAVEДЄs the value of version increases, the number of cells (square black and white dots) included in the QR code increases, and the image size and the information capacity increase.

The version of the QR code of the generated image can be set to version.ДЇor the relationship between the information capacity and versions of QR code, refer to the official page of Denso Wave below. QR code version of the generated image: version
