Special-shaped two-dimensional matrix barcode construction method

Abstract

The invention provides a special-shaped two-dimensional matrix barcode construction method. The method includes the steps: acquiring the image print resolution of a printing device; acquiring boundary dimensions of a special-shaped two-dimensional matrix barcode symbol area to be printed on a text; defining module dimensions; defining overall dimensions of a special-shaped two-dimensional matrix barcode symbol; determining a module quantity initial value M as X4 / X3; determining the final module quantity M1 and a version V corresponding to the module quantity M1; and defining completed special-shaped two-dimensional matrix barcode parameters meeting the requirements as: the module quantity M1, the version V and the module dimensions, and generating a required special-shaped two-dimensional matrix barcode symbol image by the aid of the standard generating algorithm according to the special-shaped two-dimensional matrix barcode parameters. By the method, support for a printer with unequal image print resolutions to print two-dimensional barcodes in the X direction and in the Y direction is achieved, and requirements of special texts on the two-dimensional barcodes in nonpositive directions are met.

Description

technical field [0001] The invention relates to the field of barcodes, in particular to a method for constructing special-shaped matrix two-dimensional barcodes. Background technique [0002] The matrix two-dimensional barcode is composed of several modules with equal side lengths spliced ​​in the same number in the X and Y directions. As a whole, the matrix two-dimensional barcode symbol is also a square image symbol with equal side lengths. The modules represent information in black and white respectively. 0 and 1, the matrix two-dimensional barcode can express a data packet. The larger the module, the larger the image of the matrix two-dimensional barcode symbol, and the size of the module is proportional to the size of the matrix two-dimensional barcode symbol. If the area of ​​the matrix two-dimensional barcode symbol is limited, then if you want to accommodate more information, you need to define the size of the module to be relatively small, but the size of the modul...

Problems solved by technology

In some special applications, this kind of matrix two-dimensional barcode symbols and special equipment printing or printing cannot be implemented. For example, barcode printers cannot be used in practical applications, and the printing equipment used does not support X direction and The image printing resolution is the same in the Y direction, that is to say, the normal square matrix two-dimensional barcode cannot be printed; also, when the area reserved for the text is expected to print a rectangular matrix two-dimensional barcode

The above problems are usually problems that the existing barcode technology cannot solve and realize well.
