Fig. 3 is a schematic flow chart showing a method of displaying a two-dimensional barcode according to an embodiment of the present invention.

Referring to Fig. 1, a method of generating a two-dimensional barcode is applied to a server 10. The server 10 includes at least a processing unit 110, a storage unit 130, and a network module 150, and the processing unit 110 is electrically connected to the storage unit 130 and the network module 150. The server 10 is connected to the network 30 by the network module 150. The remote device 20 includes at least a processing unit 210, a storage unit 230, a network module 250, and a user interface 270, and the processing unit 210 is electrically connected to the storage unit 230, the network module 250, and the user interface 270. The remote device 20 can connect to the network 30 via the network module 250. Therefore, the server 10 and the remote device 20 can communicate with each other via the network 30. The user interface 270 can be a touch screen, a combination of a general display screen and a plurality of physical buttons, or a combination of a touch screen and one or more physical buttons. For the convenience of explanation, The user interface 270 is used as a touch screen as an example for operation.

Referring to Figures 2 and 3, the processing unit 110 provides a setting web page (step S410). The processing unit 210 receives the setting webpage via the network 30 and displays it on the user interface 270 for the user to select, input and transmit information to the setting webpage through the user interface 270 (to the server 10) (step S610).

After the user completes the setting, the processing unit 210 outputs a setting signal via the network 30 using the setting web page (step S620). Then, the processing unit 110 receives the setting signal from the remote device 20 via the network 30 using the setting webpage (step S420), and generates corresponding bar code information according to the setting signal (step S430).

For example, in the case of an electronic ticket, a set web page can order a web page for a ticket. The processing unit 210 receives the ticket ordering webpage via the network 30 and displays it on the user interface 270 for the user to place a ticket order on the ticket ordering webpage through the user interface 270. After the user completes the order, the processing unit 210 outputs a purchase signal via the network 30 using the ticket ordering web page. Then, the processing unit 110 receives the purchase signal from the remote device 20 via the network 30 by using the ticket ordering webpage, and correspondingly generates the ticket information (ie, barcode information) of the ticket purchased by the user according to the order signal. Here, the ticket information may be an implementation time, an implementation time, an implementation location, a program name, a price, a seat, a member number, a serial number, a discount message, or a combination thereof.

In the case of authentication information, setting a web page can set a web page for a certification message. The processing unit 210 receives the authentication information setting webpage via the network 30 and displays it on the user interface 270 for the user to input and/or select the authentication information on the authentication information setting webpage through the user interface 270. After the user completes the input and/or selection, the processing unit 210 The setting information is output via the network 30 using the authentication information setting web page. Then, the processing unit 110 receives the setting signal from the remote device 20 via the network 30 by using the authentication information setting webpage, and correspondingly generates the corresponding authentication information (ie, barcode information) according to the setting signal. Here, the certification information may be a company name, a job number, a job title, a name, a serial number, or a combination thereof.

Then, the processing unit 110 calls the barcode generator to start and initialize the barcode generator (step S440). For example, in step S440, the processing unit 110 first creates a window element (FORM), then establishes a bar code generator in the security control element, and then adds the bar code generator to the window element. The security control component is mainly a software that can be executed under different operating system environments. For example, in this embodiment, the security control component can be an ActiveX control component developed by Microsoft Corporation and runs under the Windows operating system. In other embodiments, the security component can also be a software running under Android or other operating systems. Moreover, the security control component can be directly mounted on the server 10, or can be executed in a plug-in manner, and is not limited. When the security component is an ActiveX control component, the barcode generator can be AxSQRCmaker.

The processing unit 110 uses the barcode generator to convert the barcode information into a plurality of divided images in the form of a two-dimensional barcode, and sequentially draws the divided images into a picture element (step S450). Here, each divided picture has the same picture size. Moreover, each divided picture may be an independently readable two-dimensional barcode or an independently unreadable two-dimensional barcode. The independently readable 2D barcode means that scanning a single divided image can convert and obtain part of the barcode information carried by the image. An independent and unreadable 2D barcode means that a single scanned image cannot be converted to obtain part of the barcode information carried by it.

Among them, the 2D barcode can be Data Matrix, MaxiCode, Aztec code, QR code (Quick Response Code), Vericode, PDF417 code, Ultracode, Code 49, Code 16K, Code one, CP code, Codablock F code, Tian word code, or Han Xin code.

In an embodiment of step S450, referring to FIG. 4, taking the QR code as an example, after the barcode generator is initialized, setting the component attributes of the barcode generator (step S451), for example, drawing mode, number of divisions, and intermediate Blank size, border blank size, data content, etc. Taking AxSQRCmaker as an example, the component attributes to be set are shown in Table 1 below.

Next, the size of a single picture is obtained (step S452). And, the picture element is created in accordance with the size of the single picture (step S453), and the size of the picture element is set in accordance with the size of the single picture (step S454). In step S453, the processing unit 110 defines a storage block of the generated divided picture in the storage unit 150. In step S454, the processing unit 110 sets the height of the picture element to the height of a single picture, and sets the width of the picture element to be the sum of the widths of all the divided pictures.

Then, the processing unit 110 sequentially generates each divided picture according to the barcode information and the number of divisions. Here, the processing unit 110 first determines whether the picture index is greater than the number of divisions (step S455). When the picture argument is not greater than the number of divisions, the processing unit 110 calculates the drawing position using the current picture argument and the width of the single picture (step S456). Then, the processing unit 110 generates a divided picture according to the barcode information and the number of divisions, and draws the divided picture generated according to the drawing position position in the picture element (step S457). After the rendering is completed, the processing unit 110 increments the picture argument by one (step S458).

Next, returning to step S455, the processing unit 110 determines again whether the current picture index is greater than the number of divisions. If not, the processing unit 110 continues to perform step S456 to continue to generate the next divided picture. If so, the processing unit 110 completes the drawing of all the divided pictures. For example, referring to FIG. 5, assuming that the number of divisions is 4, the picture element 50 has four divided pictures 51, 52, 53, 54, and the divided pictures 51, 52, 53, 54 are sequentially arranged. Here, the divided pictures 51, 52, 53, 54 have the same size and form.

Then, the processing unit 110 performs transmission encoding on the picture element having the divided pictures to generate a transmission data (step S460), and uses the network module 150 to transmit the transmission data to the remote device 20 via the network 30 (step S470). ). For example, the processing unit 110 Re-encodes picture elements having such divided pictures into transmission data using Base64.

The processing unit 210 receives the transmission data returned by the server 10 via the network 30 by using the network module 250 (step S630), and converts the received data format of the transmission data to generate (revert back) the picture element (step S640). For example, in an embodiment of step S640, processing unit 110 decodes the transmission data using Base64 to transfer the transmission data back to the byte array. Processing unit 110 then converts the array of bytes into a picture file.

Next, the processing unit 210 stores the generated picture elements in the storage unit 230 and displays them on the user interface 270.

On the display, the processing unit 210 obtains the size of a single picture according to the number of pictures and the size of the picture element (step S650). The processing unit 210 sequentially cuts the picture elements according to the size of the single picture to sequentially obtain the divided pictures, and sequentially displays the divided pictures on the user interface 270 (step S660).

In an embodiment of step S660, referring to FIG. 6, the processing unit 210 first determines whether the picture index is greater than the number of pictures (step S661). Here, the number of pictures is the total number of pictures in the picture element.

When the picture argument is not greater than the number of pictures, the processing unit 210 crops the picture element according to the size of the single picture to obtain the first divided picture as the display picture (step S662).

After the display picture is obtained, the processing unit 210 adjusts the size of the display picture according to the display resolution of the user interface 270 (step S663), and then displays the display picture on the user interface 270 for a predetermined time (step S664). Here, the predetermined time is, for example, 50 milliseconds.

After the display, the processing unit 210 increments the picture argument by one (step S665). then Returning to step S661, the processing unit 210 again determines whether the current picture citation is greater than the number of pictures. If not, the processing unit 210 continues to perform step S662 to continue cutting the picture element to obtain the next divided picture as the display picture. If so, the processing unit 210 completes the display of all the divided pictures.

For example, taking the picture element 50 shown in FIG. 5 as an example, the number of pictures at this time is 4. Here, the processing unit 210 first displays the divided picture 51 as a display picture according to the picture index 1 and displays it on the display position P of the user interface 270 for 20 milliseconds (as shown in FIG. 7A), and increments the picture index by one. Next, the processing unit 210 displays the divided picture 52 as a display picture according to the current picture index 2 and displays it on the same display position P of the user interface 270 for 20 milliseconds (as shown in FIG. 7B), and adds 1 to the picture index. . Then, the processing unit 210 displays the divided picture 53 as a display picture according to the current picture index 3 and displays it on the same display position P of the user interface 270 for 20 milliseconds (as shown in FIG. 7C), and adds 1 to the picture index. . Subsequently, the processing unit 210 displays the divided picture 54 as a display picture according to the current picture index 4 and displays it on the same display position P of the user interface 270 for 20 milliseconds (as shown in FIG. 7D), and adds 1 to the picture index. .

Moreover, when the current picture citation is greater than the number of pictures, the processing unit 210 may reset the picture citation (step S667), and then return to step S662 to continue the subsequent steps to redisplay each of the divided pictures in sequence. And so on, until the user operation stops displaying. In other words, a complete dynamic two-dimensional bar code is formed by sequentially displaying a plurality of divided pictures, and the dynamic two-dimensional bar code is an electronic ticket or authentication information (for example, access control, identity authentication, etc., any open hard lock or software) The authentication required for the lock).

In some embodiments, referring to FIG. 8, the processing unit 210 is based on a rotation angle. The display pictures are sequentially displayed on the user interface 270 (step S664'), and the rotation angle is increased by a predetermined angle after each display (step S666). Wherein, the predetermined angle can be a fixed value or a random value.

For example, taking the picture element 50 shown in FIG. 5 and the predetermined angle as 15 degrees, the number of pictures is 4 at this time, and the rotation angle is initially set to 0. First, the processing unit 210 uses the divided picture 51 as a display picture according to the current picture index 1, and rotates the current display picture (ie, the divided picture 51) counterclockwise according to the current rotation angle (ie, 0 degree). The processing unit 210 then displays the rotated divided picture 51 on the user interface 270 (as shown in FIG. 9A), and increments the picture index by one and increases the rotation angle by 15 degrees. Next, the processing unit 210 uses the divided picture 52 as a display picture according to the current picture index 2, and rotates the current display picture (ie, the divided picture 52) counterclockwise according to the current rotation angle (ie, 15 degrees). The processing unit 210 then displays the rotated divided picture 52 on the user interface 270 (as shown in FIG. 9B), and then increments the picture index by one and increases the rotation angle by 15 degrees. Then, the processing unit 210 takes the divided picture 53 as a display picture according to the current picture index 3, and rotates the current display picture (ie, the divided picture 53) counterclockwise according to the current rotation angle (ie, 30 degrees). The processing unit 210 then displays the rotated divided picture 53 on the user interface 270 (as shown in FIG. 9C), and then increments the picture index by one and increases the rotation angle by 15 degrees. Subsequently, the processing unit 210 takes the divided picture 54 as a display picture according to the current picture index 4, and rotates the current display picture (ie, the divided picture 54) counterclockwise according to the current rotation angle (ie, 45 degrees). The processing unit 210 then displays the rotated divided picture 54 on the user interface 270 (as shown in FIG. 9D), and then increments the picture index by one and increases the rotation angle by 15 degrees. When the picture argument is greater than the number of pictures, the processing unit 210 directs the picture The number is reset to 1, and then the segmentation picture 51 is rotated counterclockwise according to the current picture citation 1 and the current rotation angle (ie, 60 degrees) and the rotated segment picture 51 is displayed on the user interface 270 (eg, Figure 9E shows), and then increase the picture argument by 1 and increase the rotation angle by 15 degrees. And so on, until the user operation stops displaying. In this way, the user interface 270 displays a two-dimensional bar code (electronic ticket or authentication information) that is rotated counterclockwise by different divided pictures. Here, although the counterclockwise rotation is taken as an example, the present invention is not limited thereto, and each divided picture may be rotated clockwise to display a clockwise rotated two-dimensional barcode on the user interface 270.

In some embodiments, referring to FIG. 10, prior to step S460, processing unit 210 embeds an advertisement picture between any two-part pictures in the picture element (step S459). For example, referring to FIG. 11, assuming that the number of divisions is four, the picture element 50 has four divided pictures 51, 52, 53, 54 and an advertisement picture 55. Here, the advertisement picture 55 is embedded between the divided pictures 52, 53. Subsequently, in step S460, the processing unit 110 performs transmission encoding on the picture element having all the divided pictures and the advertisement picture to generate a transmission material.

At the time of display, each time step S662 is performed, the processing unit 210 sequentially crops the picture elements according to the size of the single picture to obtain one of the pictures (ie, the divided picture or the advertisement picture) as the display picture. Then, the processing unit 210 displays the obtained display picture on the user interface 270 directly or according to the rotation angle.

For example, taking the picture element 50 shown in FIG. 11 and the predetermined angle as 20 degrees, the number of pictures is 5 at this time, and the rotation angle is initially set to 0. First, the processing unit 210 displays the divided picture 51 according to the picture argument 1 and the current rotation angle (ie, 0 degrees). On the user interface 270 (as shown in Figure 12A), and increasing the angle of rotation by 20 degrees. Next, the processing unit 210 displays the divided picture 52 on the user interface 270 according to the picture argument 2 and the current rotation angle (ie, 20 degrees) (as shown in FIG. 12B), and then increases the rotation angle by 20 degrees. Then, the processing unit 210 displays the advertisement picture 55 on the user interface 270 according to the picture argument 3 and the current rotation angle (ie, 40 degrees) (as shown in FIG. 12C), and then increases the rotation angle by 20 degrees. Subsequently, the processing unit 210 displays the divided picture 53 on the user interface 270 according to the picture index 4 and the current rotation angle (ie, 60 degrees) (as shown in FIG. 12D), and then increases the rotation angle by 20 degrees. Execute like this and so on until the user operation stops displaying.

In some embodiments, each of the picture elements is displayed at the same display position of the user interface 270 when displayed.

In addition, the processing unit 210 may also read out the previously stored picture elements from the storage unit 230, and then perform step S650 to sequentially display the pictures in the picture elements.
