CN101075243A - Method for scanning files by webpage - Google Patents

Abstract

A method for scanning file through web page includes realizing controls of scanner selection, scanning resolution-setting, holding format-setting and high speed scan file of driving scanner on scanner in ActiveX control element through its own Twain.dll package of Window system; realizing the scanning on file by calling on said ActiveX control element on web page and automatically uploading scanner result into server for realizing erection-free of scan file at user end.

Description

Method by the webpage scanned document

Technical field

The present invention relates to a kind of scan method of document, specifically is a kind of method by the webpage scanned document.

Background technology

Though the scan method of existing document can realize the scanning to document, needs each user that client software all is installed, brought inconvenience for the large tracts of land use of system.

Summary of the invention

The purpose of this invention is to provide a kind of method, be implemented in batch high-velocity scanning document on the webpage, a large amount of paper document electronization, convenient search and preservations by the webpage scanned document.

Technical scheme of the present invention is such: by the method for webpage scanned document, realize as follows:

One, the Twain.dll encapsulation that carries by use Windows system in ActiveX control comprises selection, scanning resolution setting, preservation formatting, the driven sweep instrument high-velocity scanning document of scanner to the control of scanner;

Two, raise with the scanning of above-mentioned ActiveX control realization at webpage, and scanning result is uploaded in the server automatically, realize that the user exempts to install scanned document document.

Above-mentionedly in ActiveX, use the Twain interface to obtain image to realize as follows:

1) opens DSM (Data Source Manager: the data source manager);

2) select DS (Data Source: data source);

3) open DS;

4) parameter is set;

5) reading scan interface;

6) obtain image;

7) close the scanning interface;

8) close DS;

9) close data source.

After adopting such scheme, the present invention adopts ActiveX control encapsulation scanner control function module, and the user only needs browsing page, does not need install software, just can realize the high-velocity scanning of document on webpage.

Description of drawings

Fig. 1 is a workflow diagram of the present invention.

Embodiment

The present invention as shown in Figure 1, realizes as follows by the method for webpage scanned document:

One, the Twain.dll encapsulation that carries by use Windows system in ActiveX control comprises selection, scanning resolution setting, preservation formatting, the driven sweep instrument high-velocity scanning document of scanner to the control of scanner.

The realization as follows of in ActiveX, using the Twain interface to obtain image:

1) opens DSM (Data Source Manager: the data source manager)

TWAIN is a data source administrator, and application program at first will be used MSG_OPENDSM message, opens the data source manager.Here need to specify a window handle, activex control is handled TWAIN message (MSG_PROCESSEVENT) in the message circulation of this window.

2) select DS (Data Source: data source)

Because may have a plurality of TWAIN equipment in the system, therefore must select a data source.Select data source that dual mode is arranged usually: to select default data source (MSG_GETDEFAULT) and show check number according to the source dialog box, select data source (MSG_USERSELECT) by the user.

3) open DS

Use MSG_OPENDS message to open data source.

4) parameter is set

Message is MSG_SET, and various parameters are set, as obtain manner, amount of images etc.Some parameter is just effective by the device drives support.

5) reading scan interface

Use MSG_ENABLEDS message, the user interface (UI) that provides is provided display device.

6) obtain image

If the user selects scanning and so on, can in the message circulation of window, get access to this incident (MSG_XFERREADY).At this moment, ActiveX control is provided with filename by DAT_SETUPFILEXFER, obtains image in file with DAT_IMAGEFILEXFER then.

7) close the scanning interface

In the message circulation of window, get access to MSG_CLOSEDSREQ or MSG_CLOSEDSOK message, can close scanning interface (MSG_DISABLEDS).

8) close DS

Message is MSG_CLOSEDS.

9) close data source

Message is MSG_CLOSEDSM.

Two, raise with the scanning of above-mentioned ActiveX control realization at webpage, and scanning result is uploaded in the server automatically, realize that the user exempts to install scanned document document.

The present invention adopts ActiveX control encapsulation scanner control function module, and the user only needs browsing page, does not need install software, just can realize the high-velocity scanning of document on webpage.

Claims (2)

1, by the method for webpage scanned document, it is characterized in that: realize as follows:

One, the Twain.dll encapsulation that carries by use Windows system in ActiveX control comprises selection, scanning resolution setting, preservation formatting, the driven sweep instrument high-velocity scanning document of scanner to the control of scanner;

Two, raise with the scanning of above-mentioned ActiveX control realization at webpage, and scanning result is uploaded in the server automatically, realize that the user exempts to install scanned document document.

2, the method by the webpage scanned document according to claim 1 is characterized in that: above-mentionedly use the Twain interface to obtain image in ActiveX to realize as follows:

1) opens DSM;

2) select DS;

3) open DS;

4) parameter is set;

5) reading scan interface;

6) obtain image;

7) close the scanning interface;

8) close DS;

9) close data source.
