The use of "first," "second," and similar terms in the description and in the claims of the present application does not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. Also, the use of the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one.

The user-defined multi-watermark combination generation method disclosed by the embodiment provides a method for adding different watermarks in different service scenes aiming at a large number of documents generated in the drug research and development and declaration processes. Different clients can create, modify, delete, configure, combine, preview and add the watermark to the document according to different service scenes and different requirements on the watermark. The problem that the product is frequently subjected to secondary development due to watermark change is solved, and the long-term investment cost of a medicine enterprise in the aspect of software is reduced. As shown in fig. 1, this embodiment discloses a method for generating a customized multi-watermark combination, which may specifically include the following steps:

and step S1, acquiring the input parameters of each selected watermark type, and querying a watermark database according to the selected watermark type to acquire the preset parameters of the corresponding type.

Wherein different watermark attributes can be defined according to the watermark type in specific setting. The watermark types may include a first watermark type, a second watermark type and a third watermark type, wherein the first watermark type may be a text watermark, the second watermark type may be a picture watermark, and the third watermark type may be a two-dimensional code/bar code watermark.

The attributes of the first watermark type, i.e., the literal watermark, may include, but are not limited to, the following. Watermark content: the watermark content can be manually input to fix the watermark content, and the constant label can be clicked to add a constant field. The add custom variable field may also be clicked on. Therefore, the text watermark content may be a combination of fixed content, constant and variable. Font size: the method is used for setting the font size of the watermark characters, and the unit is pixel px. Watermarking font: the watermark font is used to define a watermark text style, which may be defaulted to "song body", for example. And (3) character color: the watermark color mainly defines the watermark text color, and may for example default to black. The date format is as follows: the watermark format is mainly used for some watermarks which need to contain time information, but different watermarks have different requirements on the date format, so that the definition of the date format is provided.

The attributes of the second watermark type, i.e. the picture watermark, may include, but are not limited to, the following. Uploading a watermark picture: and by uploading the picture document, the watermark picture to be added by the watermark of the picture type is customized. Height of the picture: and calculating the scaling of the uploaded picture according to the actual height of the uploaded picture and the set picture height.

The third watermark type, namely the attributes of the two-dimensional code/bar code watermark are similar to those of the image watermark, but are not fixed images, and when the watermark is used, the images are dynamically generated according to the information defined by the user.

Other common configuration attributes for each watermark may also be included, which may include, for example, but are not limited to, the following parametric content. Number of watermark arrangement: and if the tiling mode is set to 1-1, the tiling mode does not exist. If 2-3 is set, 3 rows and 2 columns are shown tiled, and 2 × 3-6 identical watermarks are displayed on a page. Watermark position: the watermark location may define a watermark start location, provided the choice is: upper left corner of document page, upper right corner of document page, lower left corner of document page, lower right corner of document page, center of document page. A lateral offset distance x, and a longitudinal offset distance y may also be defined. If the initial position of the watermark is the upper left corner of the document page or the center of the document page, xy refers to offset towards the lower right; if the initial position of the watermark is the upper right corner of the document page, xy refers to offset towards the lower left; if the initial position of the watermark is the lower left corner of the document page, xy refers to the offset towards the upper right corner; if the initial position of the watermark is the lower right corner of the document page, xy refers to the offset towards the upper left corner; the gas x, y, supporting negative numbers, is offset in opposite directions to that described above. Rotation angle: the rotation angle refers to the inclination of the watermark and supports 0-360 degrees of rotation, and the rotation is clockwise according to the central position of the watermark. Transparency: the transparency is set to support the coverage degree of the watermark on the document content in different scenes. If the watermark is loaded on the watermarked content, a transparency less than 100/100 may be set as desired to prevent overwriting the document content. If the watermark is added to the blank of the document, the transparency can be set to 100/100, and the watermark is added in an opaque manner.

In the specific operation, by filling in the template variables, after the watermark template to be used is determined, the self-defined parameters, namely the variables, configured in the template are obtained. And generating an input box according to the self-defined parameters, filling out related variables by a user, and transmitting the variables to the next module to generate the watermark picture.

Step S2, generating a plurality of watermark blocks of different types according to the input parameters and the preset parameters of each type of watermark, and adding the watermark blocks of different types to the same substrate with the transparent background to form a watermark template. The watermark block refers to a file element containing corresponding watermark content, the file element can be a png picture with a transparent background containing corresponding watermark content such as characters, pictures or two-dimensional codes, and can also be a file with other formats, and the file element can be added into a substrate to form a watermark template.

The stored watermark template is mainly used for storing the configured watermark template information, and any relational or non-relational database such as MySQL, SqlServer, Oracle, MongoDB, Elasticisarch and the like can be selected for carrying out the persistence of table structured data. The storage contains fields such as the template information field of fig. 2.

In this embodiment, as shown in fig. 3, the step S2 may further include:

step S21, obtaining the configuration information of all watermarks under the template according to the configured watermark template, and circularly following each watermark type configuration parameter, wherein the watermark types comprise a first type watermark and a second type watermark.

Step S22, generating at least one first watermark block according to the input parameters and preset parameters corresponding to the first type watermark, where the first watermark block is configured to be a watermark picture containing input text generated according to the input parameters of the first type watermark.

In step S23, at least one second watermark block including a barcode or a two-dimensional code picture is generated according to the input parameters of the second type of watermark, where the second watermark block is configured as a watermark picture including a barcode or a two-dimensional code generated according to the input parameters of the second type of watermark.

The step S2 further includes: and step S24, respectively acquiring page distribution parameters and layout rule parameters in the first type watermark and the second type watermark, copying corresponding quantity of the first watermark block and the second watermark block according to the respective page distribution parameters, and then sequentially adding and arranging the first watermark block and the second watermark block on the substrate according to the respective layout rule parameters to form the watermark template.

In a preferred embodiment, the step S2 further includes:

step S101, acquiring page distribution parameters and layout rule parameters of the second type of watermark, and calculating the position of a second area where each second watermark block is arranged on the substrate.

Step S102, obtaining page distribution parameters and layout rule parameters of the first type watermark, calculating a first initial area of each first watermark block arranged on the substrate, judging whether the first initial area and the second area are overlapped, if so, calculating a superposition coefficient of the overlapped corresponding first watermark block, if the superposition coefficient is lower than a preset value, not adjusting the position of the first initial area, otherwise, moving the first initial area to the direction of reducing the superposition until the first initial area is separated from the superposition, wherein the superposition coefficient is the proportion of the superposition part of the first initial area and the second area in the area of the second area, and if not, adding the corresponding first watermark block and the second watermark block in the first initial area and the second area on the substrate.

Specifically, the arrangement position, the arrangement number and the arrangement rule of the two-dimensional code watermark on the substrate are calculated according to the page distribution parameter and the arrangement rule parameter of the second type watermark, for example, the page distribution parameter may be 1 × 2 layout, that is, two-dimensional codes are arranged per page, and the arrangement rule parameter may be that the two-dimensional code watermarks are arranged only in the page and the footer area, or that the whole page includes the text. And finally confirming the second area positions of the two generated second watermark blocks on the substrate according to the size parameter and the position parameter of the second type watermark.

And then acquiring a first initial area position occupied by a first watermark block generated by the first type watermark on the substrate according to the same way. And then judging whether the first initial area and the second area are overlapped, wherein if the two-dimensional code in the two-dimensional code watermark is overlapped with the characters in the character watermark, the character watermark possibly covers a part of a two-dimensional code graph, so that the two-dimensional code watermark is difficult to identify, and therefore, when the combined watermark is generated, whether the two-dimensional code watermark is overlapped with other watermarks needs to be judged in advance. In this embodiment, whether the first watermark block needs to be adjusted may also be determined by determining a coincidence coefficient of a coincidence area of the first initial area and the second area. The coincidence coefficient may be a ratio of the coincidence area to the corresponding second area, or a depth of the coincidence area into the second area, and may be set according to specific conditions. If the coincidence coefficient is lower than the preset value, the position of the first initial area is not adjusted, otherwise, the first initial area is moved to the direction of reducing coincidence until the first initial area is out of coincidence, and if the coincidence coefficient is not in coincidence, corresponding first watermark blocks and second watermark blocks are added to the first initial area and the second area on the substrate.

In other preferred embodiments, the step S2 can also include the following.

Step S201, respectively generating a first watermark block including a first type watermark and a second watermark block including a second type watermark according to different watermark parameters.

Step S202, obtaining the grade parameters set by the first watermark type and the second watermark type, performing priority arrangement on the second watermark type with higher priority, and calculating a second area of the second watermark block arranged on the watermark template according to the page distribution parameters and the arrangement rule parameters of the second watermark type.

Step S203, obtaining a page distribution parameter and an arrangement rule parameter of a first watermark type with a lower priority, calculating a first initial area of a first watermark block arranged on the watermark template, if the first initial area coincides with a second area, adjusting a part of variable parameters in the first watermark type to form a first watermark adjusting block, and adding the first watermark adjusting block and the second watermark block to the watermark template formed in the same substrate with a transparent background after the overlapping area of the first watermark adjusting block and the second watermark block conforms to an overlapping rule. The overlapping rule may be a ratio of the overlapping area to the corresponding second area as described in the foregoing embodiment, or a depth of the overlapping area entering the second area, which may be set according to specific situations.

In the embodiment, a grade parameter is added to each watermark type, and the adjustment priority of each watermark can be set in advance. For example, the watermark template of this time has a first watermark type and a second watermark type, and if the priority of the first watermark type is lower and the priority of the second watermark type is higher, when the watermark regions of the first watermark type and the second watermark type overlap and need to be adjusted, the watermark with higher priority can be kept still, the watermark block with lower priority is adjusted first, if there are a plurality of different types of watermarks, the watermark block with highest priority is kept still, and other watermark blocks are sequentially adjusted from low to high according to the priority. The hierarchical adjustment of the combined watermark is realized by setting the priority of each watermark type, and each type of watermark can be adjusted more reasonably according to the importance degree of each watermark type to avoid mutual influence.

In this embodiment, step S203 may further include:

step S2031, obtaining the page distribution parameters and layout rule parameters of the first watermark type with lower priority, generating at least one first watermark block, and calculating the location parameters of the first initial area correspondingly disposed on the watermark template.

Step S2032, if the first initial area and the second area are overlapped, acquiring a first variable with an adjustable attribute in the first watermark type, and correspondingly adjusting the first watermark block according to the attribute of the first variable to form a first watermark adjustment block.

If the first initial area and the second area are overlapped, a plurality of first variables with adjustable properties in the first watermark type are obtained. And comparing the changeable grades in the plurality of first variables, acquiring the parameter attribute of the first variable with the highest changeable grade, and performing corresponding changing operation on the first watermark block according to the parameter attribute to form a first watermark adjusting block.

For example, the first variable is a watermark angle parameter, a watermark position parameter and a watermark size parameter, and if the changeable level of the watermark angle parameter is the highest, the watermark angle parameter of the first watermark block is preferentially adjusted when the first initial area and the second area are overlapped. Specifically, the parameter attribute of the watermark angle parameter is acquired, if the first watermark type is a character watermark, the minimum watermark area of the character watermark is acquired, and a first watermark adjusting block is acquired after the minimum watermark area is rotated by a preset angle, wherein the first watermark adjusting block comprises the position information of the minimum watermark area.

Step S2033, acquiring a superposition area of the first watermark adjusting block and the second watermark block, calculating whether the superposition area meets a preset superposition rule, if so, adding the first watermark adjusting block and the second watermark block to a watermark template formed in the same substrate with a transparent background, and if not, returning to the previous step to adjust the first watermark adjusting block again until the superposition area meets the preset superposition rule.

In this embodiment, a changeable level is added to a parameter having an adjustable attribute in each watermark type, and the priority of the adjustment operation for each watermark can be set in advance. For example, the first watermark type in the current watermark template needs to be adjusted, the variable with the highest changeable level can be obtained for modification and adjustment, and then when the variable with the highest changeable level cannot meet the requirement of overlapping two watermark blocks after being adjusted, the variable with the second highest changeable level is modified and adjusted. The changeable grade is set for each adjustable variable in the watermark type, so that different sequential adjustment actions of a certain watermark type in the combined watermark are realized, and the watermark adjustment actions can be set more reasonably in a self-defined manner to combine the watermarks for adjustment so as to avoid mutual influence.

In a specific embodiment, the generating of the watermark picture is to generate the watermark picture according to attribute information configured by each watermark under the configuration of the watermark template. And the system acquires the configuration information of all watermarks under the template according to the selected/configured template and circularly tracks the configuration information of each watermark. If the watermark is a character watermark or a two-dimension code/bar code watermark, the system can analyze the watermark content and user input variables, global variables and fixed contents to generate final watermark content. The two-dimension code/bar code can be drawn according to the watermark content to generate a bar code/two-dimension code picture, and the bar code/two-dimension code watermark type is changed into a picture watermark type. Then generating a watermark picture according to watermark configuration, which mainly comprises the following steps:

a transparent watermark template background is drawn with a java. According to the definition (for example, the definition is n), the length and the width of the template background need to be n times of the document page to be watermarked, and the larger the value of n, the larger the background pixels, and the higher the definition of the final generated watermark template image. When all watermarks under the template are generated, the length and the width of a picture, the size of characters, the offset distance and the like are also amplified by n times. And then slicing the background of the template according to the tiling configuration. E.g. 2 x 3, i.e. 2 watermarks are tiled per row and 3 watermarks are tiled per column, then 6 tiles are needed. The width of each slice is half of the width of the template background, and the height of each slice is one third of the height of the template background. The upper left corner position coordinates of each sheet are then recorded, as well as the width and height of each sheet.

In case of text watermarking, the system needs to create a java.aawt.font object according to the font style, font color, and font size configured by the watermark, where the font size needs to be enlarged according to the definition, and the enlargement ratio of the font is, if the definition n × 3/4. And then creating and generating a java. Then, a java.aawt.dimension object is created according to the java.aawt.fontmetrics and the watermark content, and then the height and width of the character watermark are obtained according to the java.aawt.dimension object. Where java.aawt.font is used to define font information such as font size, font type, font lines. java, at, graphics2d is used to define a painting brush, which can define the painting range, i.e. the length and width of the background picture of the watermark, whether the background picture is transparent, the color of the painting brush, and other information. Font measurement attribute of java, at, fontmetrics, the font measurement information can be obtained by specifying the brush attribute and the font attribute and calculating.

Dimension information of java, a wt, dimension can define the font content, and the length and width of the specified font content can be obtained by combining the font measurement attribute.

If the image watermark is the image watermark, the system firstly obtains the image object and amplifies the length and the width of the image by n times according to the definition n. And if the height of the watermark of the picture is configured, scaling according to the proportion of the actual height of the picture to the configured height, and then acquiring the height and the width of the watermark picture.

And then circularly dividing the slices according to the position coordinates of the upper left corner of each slice. And generating an upper left corner coordinate object java. It should be noted here that the starting position of the offset is different, and the direction of the offset is also different. And then acquiring the coordinates of the upper left corner of the watermark on each fragment according to java. And circulating the coordinates of the upper left corner of each watermark, judging whether a rotation angle rotate is configured, rotating the rotation angle rotate by the coordinates of the center of each watermark, and then drawing the watermark picture or the watermark character on the background. It should be noted here that when the watermark of the next segment is drawn, the center of the above segment of watermark is taken as the center of the circle to reversely rotate, and then the center of the current segment of watermark is rotated. The upper left corner of each slice is a watermark tiling slice, and then the central position of the watermark is positioned according to the upper left corner coordinate of each slice, the offset position and the length and width of the watermark, and the watermark rotates by taking the central position of the watermark as the center of a circle. And finally combining the watermarks to generate a template watermark picture, namely, circulating the steps, and placing all the watermark pictures under the template on the same watermark template background to finally generate a watermark template picture.

Step S3, converting the document to be processed into a target document in PDF format, reading each page of the target document circularly, adjusting the layout of different watermark blocks in the watermark template according to the content position of the page, and adding the watermark blocks to the corresponding page of the target document to generate a watermark document.

As shown in fig. 4, the step S3 includes: the method comprises the steps of obtaining the page size of a target document, adjusting the size of a watermark template to a preset multiple of a target document page, and amplifying a first watermark block and a second watermark block in the watermark template by the same multiple in equal proportion.

In this embodiment, the step further includes:

step S31, identifying each page of the target document to be added with the watermark, and acquiring the region of the text content in each page; and marking the target document page as a plurality of page types respectively according to the layout of the text content in each page, and identifying the maximum text area in the first page type as the text page. Wherein the maximum text area is a rectangular area where the text is located.

Meanwhile, pages with the same maximum text area in the target document page can be marked as a first page type, other pages can be marked as a second page type, and the maximum text area is a rectangular area. In a document, pages with the largest text area are often text pages, so the text pages are marked as a first page type, and other pages are marked as a second page type, wherein the second page type can be other pages such as a directory page, an index page, a content partition page and the like.

Step S32, judging whether at least one second watermark block exists in the initial watermark template, if so, calculating a second area of the second watermark block arranged on the initial watermark template according to the page distribution parameter and the arrangement rule parameter of the second watermark type; the second watermark block is configured to generate a watermark picture containing a bar code or a two-dimensional code according to the input parameters of the second type watermark. If the initial watermark template only has the first watermark block, generating a first area of the first watermark block arranged on the initial watermark template according to the page distribution parameters and the arrangement rules of the first watermark type, and adding the initial watermark template to each target page marked as the first page type.

Step S33, if the second region and the maximum text region overlap or the overlap region does not conform to the set overlap rule, adjusting part of the variable parameters in the second watermark type to form a second watermark adjustment block, replacing the second watermark block with the second watermark adjustment block in the initial watermark template to form a first watermark template corresponding to the first page type, and adding the first watermark template to each target page marked as the first page type. And adding a second watermark block in the initial watermark template to form a second watermark template corresponding to the second page type, and adding the second watermark template to each target page marked as the second page type.

In this embodiment, the step S33 may further include the following steps: if the second area and the maximum character area have coincidence or the coincidence area does not accord with the set coincidence rule, judging whether the line number in the watermark layout parameter in the second watermark type is more than 2, if so, modifying the line number of the layout parameter to be 2. And modifying the watermark position parameters in the second watermark type, and respectively modifying the two second watermark blocks positioned at the upper part and the lower part to enable the corresponding second areas to move upwards and downwards to form two second watermark adjusting blocks. And the second area corresponding to the second watermark adjusting block does not coincide with the maximum character area or the coinciding area accords with a set coinciding rule. And replacing the second watermark block with a second watermark adjusting block in the initial watermark template to form a first watermark template corresponding to the first page type, and adding the first watermark template to each target page marked as the first page type. Specifically, the area where the generated two-dimensional code watermark belonging to the second watermark type is located on the page text, which may cause the two-dimensional code partial pattern to coincide with the text, so that the text may damage the two-dimensional code pattern, thereby possibly causing the reduction of the two-dimensional code identification efficiency. Therefore, the position of the two-dimensional code watermark needs to be adjusted, and the position of the two-dimensional code watermark can be moved upwards or downwards to a header or footer area of a page, so that the interference of text content on the two-dimensional code watermark is avoided.

In the embodiment, the watermark template is selected/configured, so that the watermark templates used at different positions can be configured and bound according to different service requirements, and the corresponding watermark template is taken out for use according to the configuration binding information when in use; some watermark templates can be more flexibly brought out with authority, and the watermark template to be used is selected by self. Each different position refers to different functional points in the system, and the bound watermark template is obtained according to a certain rule (binding information configuration) of the service system, which is a flexible application mode of a use scene. The document file to be processed is converted into pdf, in some embodiments, word conversion pdf can also be realized by jaclob, and the template watermark is added to pdf through itextpdf, so as to finally generate a new document.

Specifically, for example, a watermark is required, a text watermark is added to the upper left corner of a file, 2 x 2 picture watermarks are tiled on the content of the file, and a two-dimensional code watermark is added to the lower right corner of the file. The system is equivalent to a watermark template and is provided with three watermarks, the type of the first watermark is a character, the defined position is at the upper left corner, and the system firstly prints the character on the upper left corner of the transparent template through character configuration information.
