The collection and production of seal images is the most important link in the application of electronic seals. Usually, they are generated by scanning, cutting out and retouching. In a normal temperature environment, ink or ink that matches the seal surface is used to continuously stamp 20 times on the stamping paper with a standard stamping force, and the most complete and clearest seal text is taken as the object of collection. Then the stamping paper containing the seal text is scanned and processed to generate image files in formats such as PNG, and then processed with drawing software such as Photoshop to finally generate the seal image. This method has low efficiency and poor accuracy in generating electronic seals, and also requires more manpower. Summary of the invention

[0070] The technical solutions in some embodiments of the present application will be described below in conjunction with the drawings in some embodiments of the present application.

[0071] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0072] At present, with the continuous development of science and technology, electronic seals have been rapidly and widely used. Electronic seals are data formats in which seal makers digitally sign the seal holder information and seal images. The seal image is a graphical representation of the appearance of the electronic seal. The collection and production of seal images is the most important link in the application of electronic seals. Usually, they are generated by scanning, cutting out and retouching. In a normal temperature environment, use ink or ink pad that matches the seal surface, and use standard stamping force to stamp on the stamping paper 20 times in a row. The most complete and clearest seal text is taken as the object of collection. Then, the stamped paper containing the seal text is scanned to generate an image file in a format such as PNG, which is then processed using drawing software such as Photoshop to finally generate a seal image. In this way, the efficiency and accuracy of generating an electronic seal are low, and a lot of manpower is also consumed. In view of this, some embodiments of the present application provide a method for generating an electronic seal image, the method comprising: obtaining drawing parameters of an electronic seal image to be drawn; determining a target electronic seal image information template corresponding to the drawing parameters based on the drawing parameters and a pre-stored electronic seal image information template; determining electronic seal description data corresponding to the drawing parameters based on the target electronic seal image information template and the drawing parameters; determining a target seal vector graphics file corresponding to the electronic seal description data based on pre-stored seal vector element components; determining a target electronic seal image corresponding to the drawing parameters based on the target seal vector graphics file. In the embodiments of the present application, electronic seal graphics are drawn using vector graphics drawing technology, which has the advantages of high visual quality of drawn graphics, not easy to deform, and low computer resource consumption, and can quickly and accurately generate electronic seal images, reduce manpower consumption, and improve the accuracy and efficiency of electronic seal image generation.

[0073] like Figure 1 As shown, an embodiment of the present application provides a method for generating an electronic seal image, the method comprising:

[0074] S101, obtaining drawing parameters of the electronic seal image to be drawn;

[0075] Specifically, the user inputs the drawing parameters of the electronic seal image to be drawn in the terminal device, and the terminal device obtains the drawing parameters, which include at least target text data and target drawing conditions, wherein the drawing parameters include at least the drawing parameters of the vector graphics and the drawing parameters of the seal, the drawing parameters of the vector graphics include at least the vector graphics width, the vector graphics height and the view area, and the drawing parameters of the seal include at least the attribute information of the seal shape, the attribute information of the text object, the attribute information of the coding object and the attribute information of the central pattern object.

[0076] S102, determining a target electronic seal image information template corresponding to the drawing parameters according to the drawing parameters and the pre-stored electronic seal image information template;

[0077] Specifically, the terminal device pre-stores an electronic seal image information template, which includes drawing sub-templates of various objects, which at least include templates of seal shape, text object, coding object, central pattern object and attachment, as shown in Table 1.

[0078] Set drawing sub-templates for different objects, and all drawing sub-templates constitute electronic seal image information templates. Electronic seal image information template is a complete set, only one, which specifies all seal elements involved in all seal types. In the process of seal image generation, users only need to fill the seal data into the template, and the elements not involved can be left blank. For example, if the drawing is not a double-ring seal, you don't need to set the template information items related to the double ring.

[0079] After obtaining the drawing parameters of the electronic seal image to be drawn, the terminal device selects drawing sub-templates of different objects corresponding to the drawing parameters from the electronic seal image information template according to the drawing parameters;

[0080] For example, if the drawing parameters include a seal shape and a text object, it is necessary to find a drawing sub-template corresponding to the seal shape and a drawing sub-template corresponding to the text object.

[0081] S103, determining electronic seal description data corresponding to the drawing parameters according to the target electronic seal image information template and the drawing parameters;

[0082] Specifically, after determining the target electronic seal image information template, the terminal device draws the target text data in the drawing parameters to obtain a vector graphics file corresponding to the drawing parameters.

[0083] S104, determining a target seal vector graphics file corresponding to the electronic seal description data according to the pre-stored seal vector element components;

[0084] Vector element components: These are graphics that often appear in a seal, such as a five-pointed star or horizontal line, which can be used as a component. These components can be used to assemble a complete seal image.

[0085] Vector graphics drawing technology has the following advantages: 1) The technology has good scalability. Almost any graphic can be rendered using vector trajectories. (2) Vector images have higher visual quality. The seal image will not be distorted after arbitrary enlargement, reduction, and format conversion. (3) Vector images use less resources during the computer processing process, which is suitable for computer automation and has low cost.

[0086] S105 , determining a target electronic seal image corresponding to the drawing parameters according to the target seal vector graphics file.

[0087] Specifically, the terminal device converts the vector graphics file according to the image format requirements to obtain the target electronic seal image corresponding to the drawing parameters. Electronic seal and electronic seal image are not the same concept. In addition to electronic seal image, electronic seal also contains other data, such as: the digital signature value of the electronic seal issuing agency for the electronic seal data.

[0088] The embodiment of the present application provides a method for generating an electronic seal image, including: specifying the drawing parameters of the electronic seal image to be drawn, and filling the seal drawing parameters into the seal image information template to form complete electronic seal description data; drawing vector graphics according to the electronic seal description data, and selecting pre-set seal vector element components as needed during the drawing process to facilitate the drawing process; according to the vector graphics file, converting the vector graphics file into a target seal image. In the embodiment of the present application, by using vector graphics drawing technology to draw electronic seal graphics, it has the advantages of high visual quality of drawn graphics, not easy to deform, and low computer resource consumption. It can quickly and accurately generate electronic seal images, reduce manpower consumption, and improve the accuracy and efficiency of electronic seal image generation. Another embodiment of the present application further supplements the method for generating electronic seal images provided in the above embodiment.

[0089] Optionally, determining a target seal vector graphic file corresponding to the electronic seal description data according to the pre-stored seal vector element components includes:

[0090] Determine the target seal vector element component corresponding to the electronic seal description data according to the pre-stored seal vector element component;

[0091] The target seal vector element components are drawn to obtain a target seal vector graphics file corresponding to the electronic seal description data.

[0092] Optionally, the drawing parameters include at least the drawing parameters of the vector graphics and the drawing parameters of the seal, the drawing parameters of the vector graphics include at least the vector graphics width, the vector graphics height and the view area, and the drawing parameters of the seal include at least the attribute information of the seal shape, the attribute information of the text object, the attribute information of the coding object and the attribute information of the central pattern object.

[0093] Optionally, the drawing parameters of the seal also include: attribute information of the attachment object, attribute information of the double rings of the ellipse, and attribute information of the inner ring of the circle.

[0094] Optionally, the target seal vector element component is drawn to obtain a target seal vector graphics file corresponding to the electronic seal description data, including:

[0095] For the target seal vector element component, the main text object, double ring object, inner ring object, central pattern, horizontal line, attachment, and coding object are drawn in sequence from top to bottom and from left to right to obtain a vector graphics file corresponding to the drawing parameters.

[0096] Some embodiments of the present application, by drawing the main text object, double ring object, inner ring object, central pattern, horizontal line, attachment, and coding object in order from top to bottom and from left to right, obtain a vector graphics file corresponding to the drawing parameters, thereby improving the accuracy and efficiency of electronic seal image generation.

[0097] Optionally, the method is not only applicable to the drawing of circular seal images, but can also be applied to the drawing of seal images of shapes such as elliptical seals, square seals, triangular seals, and diamond seals.

[0098] Optionally, in the case where the electronic seal image is a circular seal, determining the electronic seal description data corresponding to the drawing parameters according to the target electronic seal image information template and the drawing parameters includes:

[0099] Determine the configuration parameters of the circular border according to the electronic seal image information template, wherein the configuration parameters at least include the coordinates of the center of the circle, the radius of the circle, the color of the circle, the width of the circle, and whether to fill it;

[0100] According to the curvature of the circular border, determine the curvature of each character in the text object;

[0101] According to the arc of each character, determine the total arc length of the text object;

[0102] Calculate the character spacing based on the total arc length, the arc of each character and the number of characters;

[0103] Calculate the font spacing based on the width and height ratio of the text;

[0104] Draw the text object according to the text spacing, font spacing and circular border;

[0105] The double ring object, the inner ring object, the central pattern, the horizontal line, the attachment, and the coding object are drawn in sequence to obtain a vector graphics file corresponding to the drawing parameters.

[0106] Specifically, the embodiment of the present application takes a circular electronic seal as an example, and the specific description is as follows:

[0107] 1) Drawing of circular border:

[0108] The circular border mainly determines the coordinates of the circle center, the radius of the circle, the color of the circle, the width of the circle, and whether to fill it.

[0109] cx, cy: represent the coordinates of the center of the circular seal; r: represents the radius of the circular seal; stroke: represents that the color of the seal is red;

[0110] stroke-width: indicates the width of the circular edge; fill: indicates whether to fill the circular area, such as the following example:

[0111] <circle cx="2250.0000"cy="2250.0000"r="2200.0000"stroke="#00FF00"stroke-width="100.0000"fill="none" / >

[0112] 2) Draw the seal text along the arc

[0113] To draw the seal text along the arc, it is necessary to determine the starting point of the arc path where the seal text is distributed, the end point of the arc, the radius of the arc, the content of the text, the font name, color, font size, and font spacing. The calculation of font spacing is the key factor in ensuring that the text is evenly distributed on the arc.

[0114] The calculation formula for font spacing on the lower arc is described in detail below:

[0115] First, calculate the arc length of each character, such as Figure 8 As shown, line segment AB is the width of the character, r is the radius of the character baseline, and the angle φ can be calculated based on AB and r, and then the arc length of AB can be calculated through φ, thereby obtaining the arc length of each character;

[0116] According to the given parameter, the included angle of the seal body is used to calculate the total arc length of the seal body;

[0117] According to the total arc length, the calculated arc length of each character, and the number of characters in the seal text, the space between characters is calculated, space = (total arc length - arc length of each character × number of characters) / number of spaces;

[0118] The font spacing (litter-spacing) is calculated according to the aspect ratio of the text, where litter-spacing = space / text aspect ratio.

[0119] For example Figure 7The path of the defs node defines an arc path for the seal text. M9323820 indicates the starting point of the arc, 3568 3820 indicates the end point of the arc, and A2050 2050 indicates the radius of the arc. The font-family="simsun" of the text node indicates that the font is Songti, font-size:200.00 indicates the font size, the node value "36.9311" of letter-spacing indicates the font spacing value, and the node value "Beijing Co., Ltd. Test" of the textPath indicates the content of the seal text.

[0120] <defs>

[0121] <path id="path2"d="M932 3820A2050 2050 0 0,0 3568 3820" / >

[0122] < / defs>

[0123] <text font-family="simsun"xml:space="preserve"style="fill:#00FF00;font-size:200.00;font-weight:bolder">

[0124] <textPath xlink:href="#path2"textLength="2936.2021"letter-spacing="36.9311"lengthAdjust="spacingAndGlyphs"> Test of a Beijing Limited Liability Company

[0125]

[0126] Optionally, determining a target electronic seal image corresponding to the drawing parameters according to the target seal vector graphics file includes:

[0127] According to a preset format conversion algorithm, the target seal vector graphics files are converted into target electronic seal images in target formats corresponding to the preset format conversion algorithm. The target electronic seal images in target formats at least include: raster images or layout images.

[0128] Among them, the seal image format conversion and delivery mainly involves format conversion of vector graphics as required. The embodiment of the present application provides three types of format converters. According to the pre-specified target image format, different image converters can be created to respectively realize conversion from vector graphics to raster images (PNG, JPEG or TIFF format), from vector graphics to other vector formats (such as EPS, WMF format, etc.), and from vector graphics to layout formats (such as PDF, OFD format, etc.).

[0129] See the seal image format conversion and delivery process for Fig. 9 .

[0130] [1] Read vector graphics files;

[0131] [2] Convert the target image format to raster format such as PNG, JPEG, etc. as shown in the figure, and create corresponding format converters such as PNGTranscoder, JPEGTranscoder, etc.

[0136] [5] Close the input and output streams and the conversion is complete.

[0137] The above processes [2], [2'], and [2”] need to be selected according to the specific target image format. For examples of converted image files, see Fig.10 .

[0138] Some embodiments of the present application convert vector graphics into images of different formats as required, thereby realizing a method for automatically generating complex style seal images. This method is completely implemented using code programming and does not require professional image processing personnel. The cost of seal image generation can be greatly reduced, and the speed of manually making seal images is also multiplied.

The filling method can be input through the system page and then automatically filled in by the system code, or the upper system directly reads the data from the database and then automatically fills in through system code programming.
