Method and system for generating two-dimensional code with color pattern

The invention discloses a method and system for generating a two-dimensional code with a color pattern. Generation of each two-dimensional code is decomposed into several groups of functions. The method is characterized by, to begin with, carrying out composition layout; calculating the size of the two-dimensional code to be generated, and the size of a colour picture or a LOGO; generating the two-dimensional code according to the size and arranging the generated two-dimensional code in color printing composition; then, enabling the colour picture or the LOGO to be covered in the two-dimensional code; and finally, generating the two-dimensional code with the colour picture or the LOGO. The method and system are low in cost and high in qualified rate. 本发明公开了种带彩色图案的二维码的生成方法及系统，其通过将每个二维码的生成分解为几组功能，首先进行排版布局，计算需要生成二维码的大小、彩色图片或LOGO的大小，按照大小来生成二维码，并布局在彩印排版中，然后将彩色图片或LOGO覆盖在二维码中，最后生成个带彩色图片或LOGO的二维码，成本较低且良品率较高。
