Problems solved by technology

[0005] The graphics processing function in the android / windows system is a collection of existing packaged functions, which have the function of drawing various graphics including drawing barcodes. Therefore, the graphics processing function has a large amount of data and takes up a lot of storage space , in this way, it is not conducive to use in wearable devices (such as wristbands) with small storage space

Abstract

The invention discloses a method and device for generating a barcode image, and belongs to the field of computer technologies. The method comprises the steps that a wearable device receives a barcode generation instruction and acquires an original barcode plaintext corresponding to the barcode generation instruction; the wearable device performs code conversion on the original barcode plaintext according to a coding rule pre-stored in a firmware code to obtain a barcode value; and the wearable device draws the barcode value into a barcode image according to the firmware code and displays the barcode image. By means of the method, equipment similar to the wearable device having a small storage space can integrate the firmware code in a system program so as to implement generation of a barcode image under an embedded platform.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for generating barcode images. Background technique [0002] A barcode is a graphic identifier that arranges multiple black and white bars according to certain coding rules to express a set of information. Bar codes can be used to identify various information such as product names, book classification numbers, mail numbers, etc., so they are widely used in many fields such as commodity circulation, book management, postal management, and banking systems. [0003] The current process of generating barcodes generally adopts a platform based on the android (Android) / windows (windows operating system) system, calls the existing graphics processing function in the android / windows system, uses the barcode plaintext as the function input value, and uses the graphics processing After processing by the function, a drawn barcode can be obtained, wherein the plain tex...
