CN102455996A - System for automatically converting multiple document formats to swf (shock wave flash) in batch - Google Patents

Abstract

The invention provides a system for automatically converting multiple document formats to swf (shock wave flash) in batch, mainly solving the problem that the contents of documents in formats of word, ppt (power point) and the like can not be read on line in the internet field. The system is characterized in that the interfaces of microsoft office are mainly called to convert the documents in formats supported by microsoft office to PDF (portable document format) documents and then a pdf2swf tool is used to convert the PDF documents to swf documents and generate corresponding thumbnail documents. The system has the following beneficial effects: the document application websites can utilize some players to upload and play the swf documents, thus achieving the function of online document reading; meanwhile, the system can achieve the aims of using the foreground to upload documents and using the background system for automatic batch conversion by calling the windows service interfaces and performing certain technical processing based on the automatic batch processing mechanism without manual intervention.

Description

Document formats to swf batch automated conversion system

Technical field

Native system is a kind of file conversion system based on microsoft office, and this system can be automatically converted to the swf form with the document of multiple form in batches at server end.

Background technology

In the epoch of internet information blast now, the circulation way of Word message is variation more, waits until the electronic graph-text on the computing machine from traditional paper book, magazine, newspaper, and then internet news in vogue, forum, blog, microblogging etc. by now.The mode of spreading network information is more efficient, and is more convenient, and very environmental protection.Technology such as technology such as optical scanning, picture and text identification from traditional papery Word message to electronic document have been applied to every field; But how can high convenient be propagated by electronic graph-text on the internet? On internet information spreading; Compare out of Memory medium (like news, forum, blog etc.); The quantity of information that possesses document runs off few, the convenient characteristics that need not the secondary editor rapidly.But the internet of electronic document propagation at present possesses following shortcoming again simultaneously:

1, inconvenience: the user has to manually the literal in the own document copied out, pastes in the editing machine in the webpage, but also must go the composing that complicates.

2, poor user experience: existing many documentation websites are a download website mostly just, the user at all can not preview before downloading with read the content in the document, caused certain customers not meet the demand of oneself at the document of having downloaded meeting discovery download.

In order to address this problem, the external client software of existing minority can convert document into the swf form, and that the swf form possesses with browser compatibility is good, picture and text quality high definition, the advantage of the suitable Internet communication of the little grade of size.Electronic document just can online reading and drop-out amount not like this.But these softwares are faced with compatibility issues such as document format and contents and distribution's coding simultaneously, and most of software has only through manual operations, do not have the function handled automatically in batches, can't adapt to the demand that a large amount of electronic documents are propagated through the internet.。

It is swf that several companies of the U.S. and Germany mainly change document through the next batch of the interface of open office, propagates in order to the internet of electronic document.But there is compatible problem in the microsoft office document of the open office and the market mainstream, and conversion efficiency is low, and output quality is relatively poor.

The converting system of our exploitation has overcome the external disadvantage of switch technology usually, has effectively satisfied the demand that the electronic document internet is propagated.

Summary of the invention

1, document is changed the mechanism: native system has called the interface of microsoft office in order to document is converted into the pdf form, converts the pdf document into swf through development sequence again

2, in batches automatic Transformation Service: native system is through calling the windows service interface, and overall arrangement document conversion queuing mechanism makes server under open state, just can change document in batches automatically, and generates corresponding thumbnail.

Description of drawings

Fig. 1 is the switch process process flow diagram of system.

Embodiment

As shown in Figure 1, the detailed switch process of native system is following.For ability batch processing document, can in database, create station table, storage corresponding document path and transition status in table.Configure after the corresponding database connection; This system can read from tables of data automatically needs the document of conversion (can limit the quantity that at every turn reads; Here for the ease of explanation, get a line item earlier), after system's reading of data; Create a timing process simultaneously, be used to prevent that big document is long switching time.Afterwards system can judge the form of the document that will change whether correct, if incorrect, the convert failed that then reports an error, and revise corresponding transition status and be failure, otherwise continue.System begins to call the interface of office through the cipher mode opening document, if document comprises password, and the convert failed that then reports an error, and revise corresponding transition status and be failure, otherwise continue.Through the office interface document is converted into after the PDF, read the number of pages of PDF, if number of pages surpasses certain numerical value, the convert failed that then reports an error, and revise corresponding transition status and be failure, otherwise continue.This moment system will begin with the pdf document that generates page by page convert corresponding swf into, and generate the file of certain rule, the swf that generates is placed in this file.System can produce the thumbnail of first swf afterwards.If the step of above conversion surpass certain in limited time, the process that the timing process of before creating can closeall relevant conversion, and revise corresponding transition status and be failure.So far, the EOC of this document.And the conversion that gets into next document.

Claims (3)

1. a document formats is to swf automated conversion system in batches, it is characterized in that the interface through calling microsoft office and then converts document into swf, and can carry out batch automatically and change document and the corresponding thumbnail of generation.

According to claims 1 described document formats to swf automated conversion system in batches, the generation that it is characterized in that swf is through calling the interface of microsoft office, and the document conversion of having called the pdf2swf tool implementation.

3. according to claims 1 described document formats to swf batch automated conversion system, it is characterized in that adopting the windows service interface, can carry out batch automatically and change document.
