A Parameterization-Based Card Surface Image Generation Method

Abstract

The invention discloses a method for generating a card face image based on parameterization, and relates to the technical field of card image generation, including that a user selects a card face basic element on a client terminal, and adds a new element by self-definition; and sets the new element on the card face basic element The size and position of the card form an image of the card surface; the client generates parameters based on the size and position of the new element on the basic elements of the card surface; the parameters that the client will generate, the new elements added by the user, and the serial numbers corresponding to the basic elements of the card surface selected by the user Send to the server; the server calls out the basic elements of the card surface stored in the server according to the received serial number, restores the card surface image according to the received parameters and new elements, and completes the card production according to the restored card surface image. The invention enables the data transmission between the client and the server in the form of parameters, effectively reduces the bandwidth consumption of data transmission, and improves the card making efficiency.

Description

technical field [0001] The invention relates to the technical field of card image generation, in particular to a method for generating card face images based on parameterization. Background technique [0002] As a product carrying personal information, IC card is widely used in banking, telecommunications, city card, transportation, education, social security, medical care, taxation and other fields due to its safety and portability. Usually, the card surface of an IC card contains a variety of card surface elements such as images, symbols, and text, and the card surface image may be composed of multiple vector graphics files or bitmap files, so the card surface image file of an IC card may The storage space occupied is large. [0003] The user independently designs the IC card card surface through the terminal, and will use the terminal photo as a part of the IC card card surface file, plus the IC card issuer's Logo image, card organization logo, text, card surface effect ...

Problems solved by technology

[0003] The user independently designs the IC card card surface through the terminal, and will use the terminal photo as a part of the IC card card surface file, plus the IC card issuer's Logo image, card organization logo, text, card surface effect rendering file, etc., resulting in card The card image file occupies a large amount of memory. When the user finally transmits the card image file to the background through the Internet, the terminal traffic occupied by the card image file is relatively large, and the transmission time is long, which increases the probability of transmission interruption and makes the user's Poor card making experience
