As preferably, the way of intercepting the required graphic data of the test questions is to select the upper and lower boundary lines to select the corresponding range of the area of a certain question by selecting the upper and lower boundary lines according to the vertical Y-axis positioning mode, and calculate the two boundary lines in the picture. The Y-axis coordinate position of the intercepted part of the picture.

As a preference, the method of intercepting the graphic data required for the test question is to select the corresponding range of the area of a certain question by obtaining the coordinates (x, y) of the mouse click point, and by calculating the position of the point coordinates, and The difference between the x and y axis directions intercepts the part of the picture.

Preferably, the way of intercepting the graphic data required by the test questions is to select the range by clicking and dragging the mouse to extract the required pictures.

Preferably, the original test paper data is general document data or graphic data, the first conversion package converts the general document data or graphic data into PDF document data, and the PDF document data is then converted into test paper data in a displayable format in the browser.

As a preference, the edited test question data is converted into PNG or JPG test question data by the second conversion package in the server and stored in the storage package of the server for the WEB client to call and assemble the test questions.

Preferably, the original electronic test paper data loading includes at least two basic attribute information of name and creation time.

Preferably, the structured data information of the test questions includes at least two pieces of information: question type and answer.

Preferably, the WEB client is a terminal with a kernel browser control.

According to the technical scheme of the present invention: realize fast and efficient test question addition, so that the different test questions of all kinds of educators can be completed in the same adding module, and at the same time, the classification of test questions and the association of answers can be quickly completed, and the storage and storage of test questions and associated information can be automatically completed. typesetting.

In terms of the requirements for importing documents, this method is completely new. It can be used for general documents in network resources, and can also be scanned pictures of teaching plans, which is convenient for traditional users to upload their own educational resources to the network.

The use of Bitmap bitmap image data display is mainly to facilitate subsequent screenshots in the browser. The Bitmap bitmap image format is used, which is easier to convert and edit than the traditional screenshot method. It does not need to call the underlying data of the operating system, and can call the copy of bitmapdata The method to copy the picture of the desired location.

After the original test paper data is uploaded, the server automatically retrieves the corresponding conversion software through content recognition for conversion. After entering the screenshot interface, the method of adding topic information is novel and convenient, and the browser kernel’s own functions or plug-in structured data interactive controls are automatically provided by the system. The edit option in the button can automatically display the optional question type, and automatically call up the corresponding option for the question type, select or input to match the option answer or text answer to the question in the cut-out graphic , and stored in the test question database (storage package) at the same time. At the same time, the optional question types can be expanded, and users can add them to the question type information before entering the editing interface.
