[0030] Method Embodiment

[0031] According to an embodiment of the present invention, an online impression method is provided. Figure 1 : is a flow chart of an online impression method according to an embodiment of the present invention. Figure 1 As shown, the online impression method according to an embodiment of the present invention specifically includes:

[0032] In step S110, obtaining the user's online impression request and obtaining the impression template pre-stored in the database specifically includes:

[0033] When a user initiates an online impression request, the impression system obtains the impression template from the database of the backend server. The impression template refers to the standard pattern or model used to generate a seal, which usually includes information such as shape, text, pattern, and color.

[0034] In step S120, the impression collection form uploaded by the user is obtained and displayed on the client, which specifically includes:

[0035] When the user selects the impression collection form, the impression system provides the impression collection form from the background server. The user can transmit the impression collection form to the background in real time, or directly select an existing impression collection form from the background server. The impression collection form is a form or file for recording or saving seals;

[0036] In step S130, a specific seal template is selected from the seal templates, the specific seal template is customized to obtain a final seal, and the final seal is displayed in the preview area of ​​the client, specifically including:

[0037] After obtaining the impression collection table, select a specific seal template from the impression templates through the drop-down menu, convert the specific seal template into a hash value, and perform security verification through the hash value;

[0038] Since stamps have diverse characteristics, the specific stamp template is set to include custom options for width, height, color and sampling algorithm. Preferably, the custom options can be expanded according to actual conditions, such as coloring settings and shape changes. If the shape needs to be changed, the text remains unchanged while the outline is changed. In an embodiment of the present invention, the custom selection is implemented as an optional button, a numerical value filling or a sliding bar.

[0039] Among them, the sampling algorithm includes the original, scanned, Gaussian blurred and similar sampled parts of the specific seal template. The specific seal template is the original, so the button for the original is not displayed on the interface. The custom option is executed to obtain the final seal.

[0040] In step S140, the impression area marked by the user in the impression collection table is obtained, and the color of the impression area is checked. After the color is checked, the final seal is printed in the impression area to obtain the impression result;

[0041] Get the rectangular area marked by the user through the mouse click event as the template area.

[0042] During the stamping process, if the stamp base color is white or close to white, it can ensure that the text or pattern on the stamp is clearly visible, especially when using red or other dark-colored stamps. Therefore, it is necessary to check the stamp area for non-white colors, obtain the preset color threshold range, traverse the pixels in the stamp area, and take the pixels exceeding the color threshold range as non-white pixels;

[0043] In the embodiment of the present invention, no color format is required. Common color formats include RGB or HEX. The RGB model includes three channels: red, green, and blue. The numerical RGB three channels of pure white are (255, 255, 255). The color threshold range can be set from (240, 240, 240) to (255, 255, 255), and the HEX representation can be set from #F0F0F0 to #FFFFFF.

[0044] If the proportion of non-white pixels to the total pixels in the stamp area exceeds the ratio threshold, the non-white screening fails and the non-white pixels are processed in turn using the mean filtering method, that is, the average value of the surrounding pixel values ​​is calculated for the non-white pixels and the average value is assigned to the center; otherwise, the non-white screening passes and there is no need to process the non-white pixels, which does not affect the normal stamp display.

[0045] After color checking, the stamp needs to be printed in the stamp area. It is necessary to ensure that the final stamp can be placed in the center of the rectangular area specified by the user as much as possible to enhance the display effect;

[0046] Select the corresponding center point determination method according to the type of the final seal. If the type is a symmetrical figure, the center point determination method used is the centroid method. Otherwise, the center point determination method used is the minimum circumscribed rectangle determination method. The center point determination method is executed to obtain the seal center.

[0047] The centroid method is to calculate the average position of all points as the seal center, which is relatively simple to calculate. The minimum enclosing rectangle is to take the center of the minimum enclosing rectangle of the final seal as the seal center. If the shape of the figure is irregular and has a large deformation, the centroid method may lead to inaccurate results, but the minimum enclosing rectangle can adapt to irregular shapes.

[0048] Determine the matrix center of the stamp area, move the stamp center of the final stamp to coincide with the matrix center, and scale the final stamp completely into the stamp area, using full proportional scaling.

[0049] In step S150, the impression result is trimmed, adjusted and uploaded, which specifically includes:

[0050] The impression result is the final form of the impression area of ​​the final seal in the impression collection table. How to crop it depends on the specific application scenario. For example, if you only need to save part of the information in the table or there is interference outside the collection table, you can remove the redundant part by cropping.

[0051] The method further comprises:

[0052] In step S160, the impression template in the database is added or modified.

[0053] Figure 2 is a schematic diagram of the process architecture of an embodiment of the present invention, such as Figure 2 As shown, the interaction process between the user, the impression system and the server is demonstrated.

[0054] To sum up, in response to the existing problems, this invention provides an online imprinting method, in which users can choose existing templates to simplify operations during the imprinting process; in addition, it supports custom settings, and users can flexibly adjust according to actual needs. The parameters that can be set include width, height, color and sampling algorithm; in the stamping process, the stamping area marked by the user needs to be checked for non-white colors to ensure that the text or pattern on the seal is clearly visible; and according to the seal type, the checked seal is printed in the stamping area. If the type is a symmetrical figure, the center point determination method used is the centroid method, otherwise the center point determination method used is the minimum circumscribed rectangle determination method, which fully considers the characteristics of different shapes to ensure that the final seal can be placed in the center of the rectangular area specified by the user as much as possible to enhance the display effect.

[0060] Select a specific seal template from the stamp templates through the drop-down menu, convert the specific seal template into a hash value, and perform security verification through the hash value;

[0061] Set the specific seal template including custom options of width, height, color and sampling algorithm, where the sampling algorithm includes the original, scanned, Gaussian blurred and similar sampled parts of the specific seal template, and execute the custom options to get the final seal.

[0062] The impression module 36 is used to obtain the impression area marked by the user in the impression collection table, perform color screening on the impression area, and after the screening passes, print the final seal in the impression area to obtain the impression result, which is specifically used for:

[0063] Get the rectangular area marked by the user through the mouse click event as the template area.

[0064] Perform non-white screening on the stamp area, obtain a preset color threshold range, traverse the pixel points in the stamp area, and regard the pixel points exceeding the color threshold range as non-white pixel points;

[0065] If the proportion of non-white pixels to the total pixels in the stamp area exceeds the ratio threshold, the non-white screening fails and the non-white pixels are processed in turn using the mean filtering method; otherwise, the non-white screening passes.

[0066] Select the corresponding center point determination method according to the type of the final seal. If the type is a symmetrical figure, the center point determination method used is the centroid method. Otherwise, the center point determination method used is the minimum circumscribed rectangle determination method. The center point determination method is executed to obtain the seal center.

[0067] Determine the matrix center of the stamp area, move the stamp center of the final stamp to coincide with the matrix center, and scale the final stamp completely into the stamp area.
