Embodiment 1

[0039] Embodiment 1, the specific method of writing and displaying it is as follows:

[0040] see Figure 5 ,

[0041] Step 100, program preparation, start the handwritten annotation function through the menu selection, subtract 1 second from the current system time (1 second is the set time value), save it as the pen-up time, and stop monitoring the mouse movement event;

[0042] After starting the handwriting function, in step 101, the program always monitors the keyboard to see if the Ctrl+C key is pressed, and if the Ctrl+C key is pressed, the current writing is ended, and the Ctrl+C key is not pressed at present;

[0043] Step 102, the program always monitors the mouse state. Determine if the left mouse button is pressed?

[0044] When the left mouse button is pressed (pen down) and the first stroke "丿" of the character "人" is ready to be written; enter module 1, see Figure 6 .

[0045] Step 201, subtract the current system time from the pen-up time of the last stro...

Embodiment 2

[0099] Embodiment 2, the specific method of writing and displaying it is as follows:

[0100] see Figure 5 ,

[0101] Step 100, program preparation, start the handwritten annotation function through menu selection, first set the pause time overtime flag to be true, so that it can avoid comparing with the set pause time every time to judge whether it is overtime.

[0102] Step 102, the program always monitors the mouse state. Determine if the left mouse button is pressed?

[0103] When the left mouse button is pressed and the first stroke "丿" of the character "人" is written, enter module 1, see Figure 8 :

[0104] Step 201, judging whether the pause time overtime flag is false? The initial value timeout flag is true;

[0105] Step 202, the pause time overtime flag is set to false (clear overtime);

[0106] Step 203, the program newly creates a data storage unit number D1, and creates a new stroke data list index I1,

[0107] Step 204, create a new blank bitmap G1;

[0...

Embodiment 3

[0166] Embodiment 3: When the page is turned to the page containing "person" and "two" on the blackboard, the system calls the bitmaps corresponding to the two display entities of "person" and "two" according to the content of the page, and displays them on the page , using only two steps. Instead of redrawing the first and second strokes of "person" and the first and second strokes of "two" as usual processing.

Abstract

The invention discloses a record broadcasting, class recording system writing stroke processing and displaying method. The method includes: judging whether the time interval between stop writing and start writing exceeds preset time; storing multiple strokes, not exceeding the preset time, in the same stroke storage unit, and drawing the multiple strokes in the same bitmap; if the preset time is exceeded, by the system, generating a new stroke data unit and a blank bitmap; displaying stroke data, as a display entity, of the same stroke data unit. By the method, the problems that the existing record broadcasting, class recording systems use a single stroke as a unit for storage, processing and display, moving and turning operations are complex, and display speed is slow are solved. During redisplay, the method does not need redrawing, stroke display information is called directly, and stroke display efficiency of the record broadcasting, class recording system in computers is increased.

Description

technical field [0001] The field that the present invention relates to is a method for processing and displaying written strokes in a recording, broadcasting and class recording system. Background technique [0002] As a new teaching and conference tool, recording, broadcasting and class recording systems have been applied in many schools and conference rooms. There are often a lot of blackboard writing in the teaching process. During the teaching process, it is often necessary to move these blackboard books or perform page-turning operations. For the display mode of the computer, it includes several layers of architecture such as hardware devices, device drivers, display interfaces, and application programs. Such as figure 1 The Windows system display architecture shown includes hardware devices, device drivers, GDI (graphics device interface), GDI+ engine for drawing graphics, images, and text, and platform layers (.NET, WIN32 / 64 (C++)). In order to facilitate porting,...
