Description

A Method of Realizing Automatic Typesetting Based on Clone Block

technical field

The invention belongs to the field of computer typesetting before printing, and in particular relates to a method for realizing automatic typesetting based on a clone block.

Background technique

At present, in the typesetting work, it is often encountered that a large amount of data needs to be arranged into the corresponding content of the layout. The style of these data is the same, but the content is different. For example, the telephone bills of all users of the mobile company, the bills of all users of the gas company, the statements of all users of the bank, and so on. If the method of manual typesetting is adopted, not only the workload is heavy, but also error-prone.

The automatic typesetting in the present invention refers to a computer typesetting technology that automatically generates typesetting results from batch data with the same structure according to pre-designed template styles and rules. The existing automatic typesetting technology is to create the corresponding typesetting object block according to the specific type, position, size, data content, style and other parameters of the typesetting object block set; Typesetting horizontally or vertically.

The main defect of the current method is that it is necessary to fully understand the various attributes of various layout object blocks that need to be automatically typeset, and the attributes of the layout objects that need to be set are numerous and complex, resulting in poor flexibility and consistency, and a high degree of dependence on the layout core. And a kind of typesetting method disclosed by the applicant on December 30, 2002 for "an automatic typesetting method" patent application (application number 02159177.6, published on June 18, 2003) is to divide the typesetting system into two types: The client and the server are equipped with a template library. The client user inputs the document title, text, pictures and layout template information, as well as the small layout and imposition template information required for imposition. The server is used to make the input from the client. The information is automatically processed into the content specified by the customer, including automatic production and layout and layout imposition. The server automatically feeds the processed layout and layout imposition to the client, and the client can modify it repeatedly until it meets the requirements. However, the problem to be solved by this method is to automatically synthesize the typesetting results of multiple people into a large version, but it cannot solve how to automatically arrange a large amount of data on the layout.

Contents of the invention

Aiming at the defects existing in the prior art, the object of the present invention is to provide a method for realizing automatic typesetting based on the clone block. This method can use a computer for automatic typesetting without having to know various specific attributes of various layout objects. It is necessary to obtain the unique identifier Id, starting point, width, and height of the layout object, so that an abstract logical block can be formed, and these logical blocks are typeset, and finally the automatic typesetting is completed through the offset of the block, so that it has a good Flexibility and consistency, ultimately greatly improving the efficiency of automatic typesetting.

In order to achieve the above object, the technical solution adopted in the present invention is: a method for realizing automatic typesetting based on clone blocks, comprising the following steps:

(1) Describe the data that needs to be automatically typeset using XML language;

(2) Use a typesetting engine to design the template layout, and the object blocks of each template layout have a unique identification Id, and then use XML language to describe the template layout, that is, use logic blocks to describe the object blocks of the template layout, and the logic blocks are objects Logical structure of the block;

(3) Realize the expansion of the automatic typesetting data in the template by adopting XPath technology, so as to obtain the logical blocks that need to be automatically typeset;

(4) Complete the data setting of each automatic typesetting layout object through the interface of setting data content;

(5) In the specified automatic typesetting area, the logical blocks recorded in the typesetting template are arranged horizontally or vertically for a series of squares at this time, and the position of each object block after typesetting is the horizontal position relative to the center of the typesetting. The coordinates and ordinates are written into the corresponding logic block parameters;

(6) Through the unique identifier Id of the object block recorded in the template, the corresponding object block on the layout is offset according to the position parameter in the logic block, so as to complete the automatic typesetting at last.

Further, in step (1), if the automatically typesetting data is not data in XML format, it is first converted into data in XML format.

Further, the logical blocks described in step (2) are text blocks, image blocks, graphic blocks and table blocks.

Further, in the logical block described in step (2), record the unique identifier Id of the layout object block, the position of the object block, that is, the abscissa and ordinate relative to the core, and the width and height of the object block.

Furthermore, when recording the unique identifier Id of the layout object block in step (2), the association between the object block and the corresponding node of the data record structure is realized through the node attribute of XML, namely databinding.

Further, in step (3), multiple logical block nodes will be obtained in the template after multiple records of the same data structure are expanded, and a corresponding number of logical blocks are copied according to the number.

The effect of the present invention is: adopt the method described in the present invention, needn't know various concrete attributes of various layout objects when utilizing computer to carry out automatic typesetting, only need to obtain the unique identification Id of layout object, starting point, width, Abstract logical blocks composed of advanced parameters, typesetting these logical blocks, and finally completing automatic typesetting through block offsets, which not only ensures the reliability of the properties of the layout objects, but also greatly reduces the dependence on the typesetting core. It has good flexibility and consistency, greatly improving the efficiency of automatic typesetting.

Detailed ways

Below in conjunction with specific embodiment and accompanying drawing, the present invention will be further described:

This embodiment takes the production of a work permit as an example, as shown in Figure 1, a method for realizing automatic typesetting based on a clone block, the specific steps are as follows:

(1) Use XML language to describe batch data. For data whose original format is not XML, it needs to be converted to XML format data.

The original format of the data file used in this embodiment is: Name department position Telephone photo Zhang San Development Department engineer 1501 zhangsan.jpg Li Si Marketing Department manager 1267 lisi.jpg Wang Wu Finance Department Accounting 1359 wangwu.jpg Saturday Administration Department Director 1201 zhouliu.jpg

After the above data is described in XML language, it will be expressed as a file in the following format:

</personnel information>

For XML language, please refer to XML Base W3C Recommendation 27 June 2001.

(2) Use the typesetting engine in the typesetting system to design the template layout, as shown in Figure 2, including text, images, graphics and other content, and make each template layout object block have a unique identification Id; that is, use logic blocks to describe the template The object block of the layout, the logic block is the logical structure;

Then adopt XML language to describe the logical structure (ie logic block) of the object block of the template layout described in this step, three kinds of abstract logic blocks, namely text block, image block and graphic block, are used to describe the object block of the template layout. The description of the logic block includes: record the unique identifier Id of the layout object block, the position of the block is the abscissa x-start, the y-start y-start relative to the core, the width of the block, and the height of the block; record the layout object block When the unique identifier Id is used, the association between the template layout object block and the corresponding node of the data record structure in the XML data file is recorded through the node attribute databinding, and the association between the object block and the node is one-to-one correspondence;

(3) Using XPath technology, according to the relationship between the node attribute databinding of the logical block and the data file, the expansion of the automatic typesetting data in the template is realized, so as to obtain the final logical block that needs to be automatically typeset. For the same data structure After multiple records are expanded, multiple logical block nodes will be obtained in the template, and the corresponding number of logical blocks will be copied according to the number, as shown in Figure 3, and the parameters of the corresponding logical blocks will be written into the corresponding template nodes; The Id of each logical block is set to the Id of the same template layout object block, and the content of each logical block is set according to the record content of the data file (text content for the text block; image file name for the image block; then not set); for each logic block, the typesetting engine clones a new layout object block according to the Id recorded in the logic block. There are two ways of cloning: one is realized by calling the clone block interface function provided by the typesetting engine , another method is to call the typesetting engine to copy and paste the selected block command to realize cloning. The only difference between the new layout object block and the original layout object block is that the Id is different;

For the XPath language, please refer to XML Path Language (XPath) Version 1.0W3C Recommendation 16 November 1999.

(4) Complete the data setting of each automatic typesetting layout object block through the interface of the setting data content of the typesetting engine (for the text block, replace its text content; for the image block, replace the image content; for the graphic block, do not need to replace), and Write the parameters of the corresponding logic block into the corresponding template node;

(5) In the specified automatic typesetting area, the logic blocks recorded in the typesetting template are arranged horizontally or vertically for a series of squares, and the position of each object after typesetting (x-start, y-start ) into the corresponding logic block parameters, the result is as shown in Figure 4;

(6) Through the unique identifier Id of the block recorded in the template, the corresponding object block on the layout is offset according to the position parameter in the logic block, so as to complete the automatic typesetting at last. The final result is shown in Figure 5.

After adopting the method of the present invention, it is not necessary to add description attributes in the template file for new attributes; and the existing implementation method needs to add a lot of attributes in the template file to describe the attributes of the block, such as the rotation and scaling of the block, the text Lace shading and more. Moreover, it can be seen from the above embodiments that the present invention does not need to know various specific attributes of various layout objects when using a computer for automatic typesetting, and only needs to obtain the unique identifier Id, starting point, width, and height of the layout object, etc. The abstract logical blocks composed of parameters, typesetting these logical blocks, and finally complete the automatic typesetting through the offset of the blocks.

The method described in the present invention is not limited to the examples described in the specific implementation manners, and those skilled in the art can obtain other implementation manners according to the technical solutions of the present invention, which also belong to the technical innovation scope of the present invention.
