Problems solved by technology

[0004] Due to the use of XML to mark non-text formulas such as mathematics and chemistry, the browser cannot display non-text formulas without installing the corresponding plug-in, which affects the normal browsing of the formulas by users and greatly hinders the distance teaching and training process. Teaching mathematics, chemistry, etc.

Embodiment 1

[0035] The formula editing system includes a sending end and a receiving end connected to the network, wherein the formula editing device provided by the embodiment of the formula editing device of the present invention is located in the sending end. Wherein, the sending end may be a user's computer that needs to send formula data, and the receiving end is a user computer that needs to receive and display formula data.

[0036] That is to say, the sender uses the formula editing device to edit and generate formula data with formula image information and send it to the receiver. Although the receiver's receiving end is not equipped with a formula editing device or any plug-in, because the data organization format of the formula image information in the formula data is common, for example, use the JPEG picture format to store the formula image information in the present embodiment, and will be corresponding The remark information of the formula is stored as additional EXIF ​​inf...

Embodiment 2

[0039] This situation may also exist in practice, and the formula editing device is located at the receiving end instead of the sending end, and in this case, browsing and editing of formulas can also be realized.

[0040] In this embodiment, it includes a sending end and a receiving end connected to the network, wherein the formula editing device provided by the embodiment of the formula editing device of the present invention is located in the receiving end.

[0041] After the receiving end receives the formula data transmitted from the sending end, the formula editing device is invoked to generate the formula image information when the formula data does not include the formula image information, and a picture display tool (in this embodiment, a browser) is adopted to browse the formula.

[0042] Similar to Embodiment 1, this embodiment may also include a server connected to the sending end and the receiving end, for receiving and storing the formula data sent by the sending...

Embodiment 3

[0044] Such as figure 2 As shown, this embodiment is based on the first embodiment of the formula editing system, and the formula editing device provided by the present invention is also located in the receiving end. Therefore, both the user at the sending end and the user at the receiving end can use the formula editing device to edit formulas and generate formula data. At the same time, this embodiment may also include the same server as that in Embodiment 1. In distance teaching, the server is a network server (usually a WEB server). In the interaction between the sending end, the receiving end and the server, use the formula editing device and the browser connected to the WEB server to edit the formula data from the server and / or send the edited formula data to the server to realize online editing of the formula.

[0045] The embodiment of the formula editing method corresponding to the present invention, such as image 3 shown, including the following steps:

Abstract

The invention relates to a formula editor, which comprises a formula editing module and a formula memory module, wherein, the formula editing module is used for receiving formula remark information, generating formula image information according to the formula remark information and transmitting the formula image information and the corresponding formula remark information to the formula memory module; the formula memory module is connected with the formula editing module and used for storing formula data which comprises the formula image information and the formula remark information. The invention also relates to a formula editing system, a formula editing method and a formula display method which are based on the device. The invention can realize browsing of non-text formulas by users and online editing of the non-text formulas under the condition that a browser is not provided with any plug-in.

Description

technical field [0001] The invention relates to a formula editing device, a formula editing system, a formula editing method and a formula display method. In particular, a formula editing device, a formula editing system, a formula editing method and a formula display method suitable for browsers belong to the technical field of the Internet. Background technique [0002] With the development of Internet technology, geographically dispersed users can gather in one place through the Internet, and conduct real-time information exchange and sharing at a distance. Therefore, distance learning has become one of the important applications of the Internet. In distance teaching, participants often need to browse and edit formulas through a browser, but in ordinary browsers, it does not support the input and editing of non-text formulas such as mathematics and chemical formulas. formulas, they cannot be edited in normal form. [0003] In the prior art, Extensible Markup Language (X...
