Description

Technical Field

[0001] The embodiments of the present invention relate to computer technology, and more particularly to a tag processing method, apparatus, electronic device, and storage medium. Background Technology

[0002] In the manufacturing sector, using multi-color labels to identify items has become a standard practice. Taking two-color labels as an example, their printing principle involves a thermal printer heating the two-color paper to different temperatures to produce different colors.

[0003] Before printing labels, the image to be printed is usually processed into a binary image and sent to the printing device. If two-color label printing is required, the binary image processing operation needs to be performed twice according to the two color identifiers, and the two binary images are sent to the printing device. The printing device combines the two received binary images to determine the printing color required for each printing area, and then prints the two-color label.

[0004] Existing solutions are cumbersome, resulting in low printing efficiency for printing equipment. Summary of the Invention

[0005] This invention provides a tag processing method, apparatus, electronic device, and storage medium, which can improve existing tag processing solutions.

[0006] In a first aspect, embodiments of the present invention provide a label processing method, including:

[0007] Obtain a printable image containing multiple printable areas, wherein the multiple printable areas include at least two color identifiers;

[0008] Based on the arrangement of the multiple areas to be printed, determine the target color identifier corresponding to each area to be printed, and obtain the printable label of the image to be printed;

[0009] The label to be printed is sent to the printing device so that the printing device prints the label according to the target color identifier.

[0010] Secondly, embodiments of the present invention provide a label processing apparatus, the apparatus comprising:

[0011] An image acquisition module is used to acquire a printable image containing multiple printable areas, wherein the multiple printable areas include at least two color identifiers;

[0012] The identifier determination module is used to determine the target color identifier corresponding to each of the multiple areas to be printed based on the arrangement of the multiple areas to be printed, and to obtain the printable label of the image to be printed;

[0013] The label sending module is used to send the label to be printed to the printing device, so that the printing device can print the label according to the target color identifier.

[0014] Thirdly, embodiments of the present invention also provide an electronic device, the electronic device comprising:

[0015] At least one processor; and

[0016] A memory communicatively connected to the at least one processor; wherein,

[0017] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the tag processing method according to any embodiment of the present invention.

[0018] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions that are used to cause a processor to execute the tag processing method described in any embodiment of the present invention.

[0019] The label processing scheme of this invention first acquires a printable image containing multiple printable areas, each including at least two color identifiers. Then, based on the arrangement of these areas, a target color identifier is determined for each printable area, resulting in a label for the printable image. Finally, the label is sent to a printing device, which prints the label according to the target color identifier. This embodiment, by pre-determining the color identifier for each printable area, only requires a single binary image conversion of the label with color identifiers. This allows the printing device to print the label based on the binary image marked with color identifiers, solving the problem of multiple binary image processing steps required in existing solutions based on the color type of the label. This simplifies the processing flow and improves printing efficiency.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] Figure 1This is a schematic flowchart of a label processing method provided in an embodiment of the present invention. This embodiment is applicable to situations where labels to be printed are processed before printing. The method can be executed by a label processing device, which can be implemented in hardware and / or software and can be configured in computer equipment such as a server. (Reference) Figure 1 The method may specifically include the following steps:

[0032] S110. Obtain the image to be printed, which contains multiple areas to be printed.

[0033] The image to be printed can be understood as the label image that the staff sets on the application integrated into the terminal device to be printed according to actual work needs. The terminal communicates with the printing device so that the printing device can perform the corresponding printing operation based on the label to be printed in subsequent steps. The terminal device can be a computer device or a smart mobile device (such as a smartphone or smart tablet). The specific type of terminal device is not limited here.

[0034] The area to be printed can be understood as the area corresponding to each attribute to be printed, edited in the text editing area of ​​the application; that is, one area to be printed can correspond to one attribute name. The current area to be printed can include product information areas, company information areas, barcode areas, and QR code areas, etc. The application may contain an attribute library that can meet the functional requirements of various types of labels to be printed, allowing staff to select the target attribute from the attribute library and then drag and drop it to the text editing area to form a printing area. Since labels generally contain multiple attributes, the image to be printed provided in this embodiment includes multiple printing areas.

[0035] Please refer to Figure 2 ,like Figure 2 As shown, Figure 2 This is a schematic diagram of a printable image provided by an embodiment of the present invention. In the diagram, company name, product number, brand, year, etc., can be understood as attributes selected by staff from an attribute library according to actual needs, forming corresponding printable areas. When all required printable areas are selected, a printable image containing multiple printable areas is obtained. For the content corresponding to each printable area, a stamp can be manually affixed to the label in the corresponding area after the label corresponding to the printable image is printed. Optionally, when all required printable areas are selected and the printable content corresponding to each printable area is filled in according to actual needs, a printable image containing multiple printable areas is obtained. Whether the printable image specifically includes the printable content corresponding to each printable area is not limited in this solution and depends on the actual application scenario.

[0036] The content and arrangement of the image to be printed are not limited to the illustration, and there may be cases where multiple areas to be printed completely overlap, partially overlap, or do not overlap.

[0037] The multiple printing areas provided in this embodiment of the invention include at least two color identifiers. The purpose of setting at least two color identifiers is to facilitate users' intuitive analysis of the corresponding content based on the different colors of the printed labels, serving as a prompt and distinction. Currently, the at least two color identifiers can be white, red, black, blue, or gray, etc., and the specific color type corresponding to the identifiers is not limited here, but depends on the actual function of the printing device. Figure 2 For example, the attribute names in the image to be printed and the colors corresponding to the attribute content of each attribute name can be set as the first color, and the colors corresponding to the QR codes and barcodes can be set as the second color; alternatively, the QR codes and barcodes can be set to different colors, etc. The specific color type corresponding to each area to be printed is not restricted here.

[0038] The color codes mentioned above can be represented by numbers, letters, and / or symbols. There are no restrictions on the specific way the color codes are represented, as long as the printing device can determine the corresponding color based on each color code.

[0039] S120. Determine the target color identifier corresponding to each area to be printed based on the arrangement of multiple areas to be printed, and obtain the print label of the image to be printed.

[0040] The target color identifier for each area to be printed can be determined in several ways. First, it can be determined during the user's editing of the area. For example, setting the text color of the current area to be printed to black will determine the target color identifier as black. Second, it can be determined after multiple areas to be printed have been edited. For example, after all areas to be printed have been defined, the text can be set to black and the graphics to red. The specific method for determining the color identifier for each area to be printed is not limited here.

[0041] For example, when a user edits the font, they can choose black as the font color; when setting the barcode, they can choose black as the barcode color; and when setting the QR code, they can choose red as the QR code color. For background areas or blank spaces on the image to be printed that do not have a set color, the user can manually set them to white, or they can leave them as white by default. This allows the target color identifier for each area to be printed to be obtained based on the arrangement of multiple areas to be printed. Once the target color identifier for each area to be printed is marked, the label to be printed on the image is obtained.

[0042] S130. Send the label to be printed to the printing device so that the printing device can print the label according to the target color code.

[0043] For labels to be printed that are marked with color identifiers, the labels to be printed can be converted into binary images before being sent to the printing device. The current binary image contains different color identifiers in different areas to be printed, so that the printing device can print the labels to be printed according to the target color identifiers.

[0044] In one implementation, after receiving a label to be printed containing a target color identifier, the printing device can print the label as follows: determine the heating temperature corresponding to each area to be printed based on the target color identifier; heat and print each area to be printed according to the heating temperature to obtain the printed label.

[0045] The printing device determines the target printing color for the current area to be printed based on the identified target color identifier, and heats and prints according to the heating temperature corresponding to the target printing color, so that different colors are displayed in different areas on the obtained printed label.

[0046] The label processing method provided in this embodiment of the invention first acquires a printable image containing multiple printable areas, each printable area including at least two color identifiers; then, based on the arrangement of the multiple printable areas, it determines the target color identifier corresponding to each printable area, obtaining a printable label from the printable image; finally, it sends the printable label to a printing device, enabling the printing device to print the label according to the target color identifier. This embodiment, by pre-determining the color identifier corresponding to each printable area, only requires one binary image conversion of the printable label with color identifiers, allowing the printing device to print the label based on the binary image marked with color identifiers. This solves the problem in existing solutions that require multiple binary image processing steps based on the color type of the printable label, achieving the beneficial effects of simplified processing and improved printing efficiency.

[0047] Figure 3 This is another schematic flowchart of the label processing method provided in this embodiment of the invention. The relationship between this embodiment and the above embodiments further refines the corresponding features of the above embodiments. Figure 3 As shown, the method may include the following steps:

[0048] S210. Obtain the image to be printed, which contains multiple areas to be printed.

[0049] Multiple areas to be printed include at least two color codes.

[0050] S220. Perform grayscale processing on the image to be printed to obtain the grayscale value of each area to be printed.

[0051] The image to be printed generated by the terminal device is a color image that has already been set. In order to facilitate the determination of the target color identifier corresponding to each printing area in the image to be printed, the color image can be processed into grayscale. For the image after grayscale processing, the same color is represented by the grayscale value.

[0052] One method for grayscale processing of the image to be printed is to determine the grayscale value of each pixel using a floating-point method, and then obtain the grayscale value of each area to be printed based on each pixel.

[0053] The method of determining the grayscale value of each pixel using the floating-point method can be expressed by the following formula:

[0054] Gray=R*0.29891+G*0.58661+B*0.11448 (1)

[0055] In the above formula, Gray represents the grayscale value of the current pixel, and R, G and B represent the R, G and B values ​​corresponding to each pixel, respectively. The range of R, G and B values ​​is [0, 255], and the specific values ​​of R, G and B are based on the actual color of the current pixel.

[0056] S230. Obtain overlapping and non-overlapping areas according to the arrangement order of each area to be printed.

[0057] During the editing process of each area to be printed, there may be overlaps between them. For overlapping areas, the color inconsistency between the two areas may prevent intuitive color identification based on grayscale values. Therefore, it is necessary to determine the overlapping and non-overlapping areas based on the arrangement order of each area to be printed.

[0058] For an example, please refer to Figure 4 , Figure 4 This is a schematic diagram of another image to be printed provided in an embodiment of the present invention. Example Figure 4 For an image to be printed, assuming region A is arranged before region B, if region B is detected to overlap region A, then the image to be printed is determined to contain overlapping areas. The overlapping part is the shaded area in the figure. The remaining areas in the figure, excluding the shaded area, can be considered non-overlapping areas. Optionally, if region B is detected to overlap region A, both regions A and B can be determined to be overlapping areas, and the color indicators of the overlapping and non-overlapping parts in regions B and A can be further determined. Region C is a non-overlapping area, and so on. The specific method of dividing overlapping and non-overlapping areas is not limited here.

[0059] S231. Determine the target color identifiers for overlapping and non-overlapping areas based on the grayscale values ​​of each area to be printed.

[0060] Please continue to refer to Figure 4 When setting regions A and B, with region A as the first color and region B as the second color, and region C being the area in the image to be printed that is not covered by regions A and B, the default color (such as white) can be used. In this case, the target color identifiers corresponding to the overlapping and non-overlapping areas need to be determined based on the grayscale value of each region to be printed.

[0061] In one implementation, according to an embodiment of the present invention, determining the target color identifier corresponding to the non-overlapping area based on the grayscale value of each area to be printed can be achieved by: obtaining a standard grayscale value set, which includes standard grayscale values ​​corresponding to at least two color identifiers; and determining the target color identifier corresponding to the grayscale value of the non-overlapping area from the standard grayscale value set.

[0062] For uncovered areas, the color corresponding to each area can be determined by converting it to a grayscale image and comparing the obtained grayscale value with the standard grayscale values ​​corresponding to at least two color identifiers contained in the standard grayscale value set. When the values ​​are consistent, the target color identifier for each non-overlapping area can be determined based on the color identifier corresponding to the standard grayscale value.

[0063] For another implementation method, please refer to Figure 5 , Figure 5 This is another flowchart illustrating the label processing method provided in this embodiment of the invention. In this embodiment, determining the target color identifier corresponding to the overlapping area based on the grayscale value of each area to be printed can be achieved by the following steps S310 to S350:

[0064] S310. Obtain the target sub-region from the overlapping region.

[0065] For overlapping regions, the overlapping region can be divided into multiple sub-regions. Each sub-region includes a preset number of adjacent pixels. The current preset number can be 1, 2, 3, or 5, etc. The specific value of the preset number is not limited here.

[0066] For example, taking a preset quantity of 1 as an example, the target sub-region is determined by taking the target pixel as the center and the area formed by the pixels adjacent to the target pixel as the target sub-region. Then the current target sub-region can contain 9 pixels.

[0067] The target sub-region mentioned above is any one of the multiple sub-regions contained in the overlapping region.

[0068] S320. Calculate the average pixel grayscale value of the target sub-region based on the grayscale value of each pixel in the target sub-region.

[0069] In the current step, the average pixel grayscale value of the target sub-region is calculated by obtaining the grayscale value of each pixel, accumulating the grayscale values ​​of each pixel, and then calculating the average value.

[0070] S330. Determine the target color identifier corresponding to the target sub-region based on the average pixel grayscale value.

[0071] The method for determining the target color identifier corresponding to the target sub-region by the pixel grayscale mean can be as follows: for multiple areas to be printed that include at least two color identifiers, the grayscale value corresponding to each color can be obtained. When the pixel average of the target sub-region is closest to a certain color, the current color is determined as the target color identifier corresponding to the target sub-region.

[0072] In a preferred embodiment, the color identifier includes a first color identifier and a second color identifier; the standard grayscale value corresponding to the first color identifier is a preset value. In this step, taking red as the first color and black as the second color as an example, the grayscale value corresponding to red is 78, and the grayscale value corresponding to black is 0. Specifically, the above step S330 can be implemented in the following way:

[0073] When the average pixel grayscale value is greater than a preset value, all pixels in the target sub-region are designated as the first color identifier; when the average pixel grayscale value is not greater than the preset value, all pixels in the target sub-region are designated as the second color identifier.

[0074] Please continue to refer to Figure 4 Taking region A as red, region B as black, and the overlapping region as all regions composed of region A and region B as an example, if the average pixel grayscale value of the target sub-region is greater than 78, the target sub-region can be marked as red; otherwise, it is marked as black.

[0075] It should be noted that in all regions consisting of region A and region B, where the overlapping area is not included, all pixels in region A that do not include the overlapping part are red, and the corresponding gray value is 78. In region B, all pixels that do not include the overlapping part are black, and the corresponding gray value is 0. To simplify the calculation, steps S310 to S350 can be performed only on the overlapping part (i.e. the shaded part in the figure).

[0076] S340. Determine whether all pixels in the overlapping area have been identified to the corresponding target color identifier.

[0077] If not, then obtain the next sub-region from the overlapping region, and use the next sub-region as the target sub-region, repeating steps S310 to S330.

[0078] If so, proceed to step S350.

[0079] S350, Obtain the target color identifier corresponding to the overlapping area.

[0080] Once all pixels in the overlapping region are identified to their corresponding target color identifiers, the target color identifier for the overlapping region can be obtained based on the marked target color identifiers. The target color identifier for the current overlapping region is either red or black, as shown in the example above.

[0081] S240: Obtain the label to be printed from the image to be printed.

[0082] Once the color marking of all areas in the image to be printed is complete, the label to be printed is obtained.

[0083] S250: Send the label to be printed to the printing device so that the printing device can print the label according to the target color code.

[0084] Another implementation involves batch printing, where the current print job includes multiple images to be printed, each image including a variable area and a fixed area.

[0085] Batch printing can be understood as printing multiple sheets consecutively in a single printing process. During batch printing, there may be situations where all content in all areas to be printed is exactly the same, or there may be situations where some content needs to be changed depending on the number of sheets printed and the printing time. For example, the current number of sheets to be printed, the current printing time, etc.

[0086] For batch printing, in order to quickly obtain the label corresponding to each image to be printed, the area where all the printed content is the same can be defined as a fixed area, and the area where the printed content varies can be defined as a variable area.

[0087] For the current image to be printed, the method further includes: obtaining the target color identifier corresponding to the previous image to be printed in the fixed area; performing the operation step of determining the target color identifier corresponding to each printing area in the variable area based on the arrangement of multiple printing areas; and obtaining the label to be printed for the current image to be printed based on the target color identifier corresponding to the fixed area and the target color identifier corresponding to the variable area.

[0088] The target color identifiers corresponding to the fixed areas identified in the previous image to be printed are saved. Only the target color identifiers corresponding to each printable area are determined for the variable areas in each image to be printed, thus obtaining the label to be printed for the current image. The advantage of this approach is that it speeds up label processing and reduces computational load. During continuous printing, it prevents printer lag caused by delayed label processing.

[0089] The label processing solution provided in this invention only requires one binary image conversion process for images to be printed that contain at least two color identifiers, shortening the image processing flow and thus improving the transmission speed. It is suitable for processing labels with various label materials and color identifiers, and has a wider range of applications.

[0090] Figure 6 This is a schematic diagram of a label processing device provided in an embodiment of the present invention. This device is suitable for executing the label processing method provided in an embodiment of the present invention.

[0092] The identifier determination module 420 is used to determine the target color identifier corresponding to each of the multiple areas to be printed based on the arrangement of the multiple areas to be printed, and to obtain the printable label of the image to be printed;

[0093] The label sending module 430 is used to send the label to be printed to the printing device, so that the printing device prints the label according to the target color identifier.

[0094] The label processing device of this invention first acquires a printable image containing multiple printable areas, each printable area including at least two color identifiers; then, based on the arrangement of the multiple printable areas, it determines the target color identifier corresponding to each printable area, obtaining a printable label from the printable image; finally, it sends the printable label to a printing device, so that the printing device prints the label according to the target color identifier. The solution provided in this embodiment, by pre-determining the color identifier corresponding to each printable area, only requires one binary image conversion of the printable label with color identifiers, enabling the printing device to print the label based on the binary image marked with color identifiers. This solves the problem in existing solutions that require multiple binary image processing steps based on the color type of the printable label, achieving the beneficial effects of simplified processing and improved printing efficiency.

[0099] The identifier determination unit is used to determine the target color identifiers corresponding to the overlapping areas and the non-overlapping areas based on the grayscale values ​​of each of the areas to be printed.

[0100] In one embodiment, the identifier determination unit is specifically used to obtain a standard grayscale value set, the standard grayscale value set including at least two standard grayscale values ​​corresponding to the color identifier; and to determine the target color identifier corresponding to the grayscale value of the non-overlapping region from the standard grayscale value set.

[0102] In one embodiment, the color identifier includes a first color identifier and a second color identifier; the standard grayscale value corresponding to the first color identifier is a preset value;

[0103] The identifier determination unit is further configured to, when the average pixel grayscale value is greater than the preset value, determine all pixels of the target sub-region as the first color identifier; and when the average pixel grayscale value is not greater than the preset value, determine all pixels of the target sub-region as the second color identifier.

[0104] In one embodiment, when the current print job is a batch print job, the current print job includes multiple images to be printed, and each image to be printed includes a variable area and a fixed area;
