In order to make the solution of the embodiment of the present invention better understood by those skilled in the art, the embodiment of the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

The embodiment of the invention provides a method and a device for adding watermarks to a contract, which automatically generate contract numbers and marking information after the examination of a contract file is completed; acquiring the contract file, reading the text of the contract file as a file stream, and writing the file stream into a text object; determining watermark correlation properties; and inserting the contract number and the marking information into the text object according to the watermark related attribute to generate a watermark version contract body, thereby realizing effective protection of the contract body.

As shown in fig. 1, a flowchart of a method for adding watermarks in a syndication according to an embodiment of the invention includes the following steps:

Step 101, automatically generating contract number and mark information after the examination of the contract document is completed.

The contract number may be automatically generated according to a predetermined rule, for example, the following contract number generation rule may be adopted:

sign-up subject number + contract underwriting department number + year (two digits) +contract type code + running number, such as: DQGW-ZH-23-ZL-001.

Of course, in practical application, the number generation rule may be set according to the actual needs of the user, which is not limited to the embodiment of the present invention.

And 102, acquiring the contract file, reading the text of the contract file as a file stream, and writing the file stream into a text object.

Specifically, the body of the contract file is read as a file stream BufferedInputStream, which is written into the Document object.

A Document object refers to an object in an HTML Document with which the HTML Document can be checked, modified, or added with content, and events within the Document processed. On a Web page, a Document object may be referenced by a Document attribute of a Window object, or directly.

Step 103, determining watermark correlation properties.

For example, watermark related attribute setting can be sequentially performed by using a seal generation tool method seal.

The watermark correlation attribute includes any one or more of the following: size (300), color (color. Light_GRAY), edge circle (e.g., set to line shape: dot-dashed line, width: 140, height: 140), inner edge circle (e.g., set to line shape: dot-dashed line, width: 132, height: 132), inner edge circle (e.g., set to line shape: dot-dashed line, width: 120, height: 120), main word (e.g., main word content is contract number, font size 30, gap 20), center word (e.g., center word content is empty string, font size 100), head-up (e.g., head-up content is empty string, font size 22, gap 10.0, gap 68).

After the setting is completed, the seal. Draw (newFile) is called, the watermark content is generated into a seal, and the seal is stored in a ZWSY. Jpg file under the appointed directory.

And step 104, inserting the contract number and the marking information into the text object according to the watermark correlation attribute to generate a watermark version contract body.

Specifically, the Aspose technical method may be invoked to transfer the Document object NEW PARAGRAPH (doc) object generated in the step 103, and transfer the doc object and set the watermark format as the picture format new Shape (doc, shape type.image).

Then, through the shape operation, the following information is set in order:

1) Watermark picture position GETIMAGEDATA (). SetImage (image),

2) Watermark gradient setRotation (0),

3) Brightness setBrightness (0.5),

4) Contrast setContrast (0.5),

5) Watermark width setWidth (60),

6) Watermark height SETHEIGHT (230),

7) Relative horizontal position

setRelativeHorizontalPosition(RelativeHorizontalPosition.PAGE)、

8) Relative vertical position

setRelativeVerticalPosition(RelativeVerticalPosition.PAGE)、

9) Text vertical alignment SETVERTICALALIGNMENT (center),

10 Text level alignment etHorizontalAlignment (horizontal alignment).

Then, watermark Para. Appendshield (shape) is called, and inserting the set watermark into the contract text.

According to the method for adding the watermark to the contract, after the examination of the contract file is completed, contract numbers and marking information are automatically generated; acquiring a contract file, reading the text of the contract file as a file stream, and writing the file stream into a text object; and then determining the watermark correlation attribute, and inserting the contract number and the marking information into the text object according to the watermark correlation attribute to generate a watermark version contract text. By adding contract number and mark information, the content of the watermark is enriched. Compared with the watermark of the fixed picture mode in the prior art, the method and the device automatically generate the watermark through programming, and improve the anti-tampering effect of the contract.

As shown in fig. 2, another flowchart of a method for adding watermarks in a syndication according to an embodiment of the invention includes the following steps:

in step 201, after the examination of the contract document is completed, the contract number and the mark information are automatically generated.

Step 202, acquiring the contract file, reading the text of the contract file as a file stream, and writing the file stream into a text object.

In step 203, watermark correlation properties are determined.

And 204, inserting the contract number and the marking information into the text object according to the watermark correlation attribute to generate a watermark version contract body.

It should be noted that, in a specific application, the marking information may be a setting frame, for example, a circular frame, a square frame, a diamond frame, and the like. In addition, the setting frame may be represented by a solid line or a broken line, and may have one or more layers. The embodiments of the present invention are not limited in this regard.

When the contract number and the mark information are inserted, the positions of the contract number and the mark information may be set arbitrarily, for example, the contract number may be placed in the setting frame or out of the setting frame, which is not limited to the embodiment of the present invention.

And 205, carrying out encryption setting on the watermark contract text to generate a watermark contract file.

For example, text may be saved as a watermarked file via a corresponding text control indiDocx, where the saved file is encrypted via control indiDocx, thereby limiting the editing process for the text.

Fig. 3 shows an example of the body of a contract after watermarking with the scheme of the present invention.

According to the method for adding the watermark to the contract, the watermark contract file is generated by encrypting the watermark contract body, so that editing processing of the body is effectively limited, and the safety of the body is ensured.

Further, in order to facilitate the user to browse the contract text, in another non-limiting embodiment of the present invention, the method may further include: and when receiving the online preview contract request, displaying the watermark version contract text.

Further, in order to meet the downloading requirement of the user on the contract, in another non-limiting embodiment of the present invention, the method may further include: and when receiving a contract downloading request, removing the watermark in the watermark version contract file, and storing the contract text after watermark removal.
