Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] The present invention proposes a stroke network conversation system and method, which mainly includes three modules of stroke encoding and decoding, stroke encoding data transmission, and stroke display synchronization, and finally realizes the synchronous display of strokes at each session end.

[0041] Described stroke coding, this coding comprises the coding of stroke code, stroke code page coding and stroke code book coding, specifically comprises the following steps:

[0042] 1. Encoding of stroke code:

[0043] Stroke B is the only stroke produced by a contact whose coordinates are P(x,y) and pressure intensity is f after the stroke attribute is selected. The stroke attributes include stroke size and shape T, and stroke color C(s1,s2 ...sm), stroke pressure sensitivity Q. Then an array (1) description available for a contact:

[0044] [T, C (s...

Abstract

The invention discloses a network session transmission method of handwritten strokes. The method comprises the following steps: stroke encoding: a server receives the handwritten strokes and packages the handwritten strokes into a stroke code book at last; the server transmits the stroke code book and a movable page number to each client through a network server; and synchronous display: the server displays movable pages in real time, the client decodes all strokes of the movable pages in the received stroke code book, and displays the strokes on each client. According to the network session transmission method disclosed by the invention, the handwritten input strokes are used as processing objects, the strokes are not formed into templates, and what is seen when what is written is realized; meanwhile, the strokes are processed with the strokes as units to keep the integrity and independency of the unit stroke data; and the network session transmission method has the advantages of being simple to realize and strong in flexibility, and can be widely used in teaching demonstration, meeting communication, network chat and other fields.

Description

technical field [0001] The invention relates to handwritten stroke input, in particular to a network session transmission method of handwritten strokes. Background technique [0002] Handwritten stroke input can be implemented in smart devices, but the input strokes still need to be converted into standard fonts or images before they can be transmitted on the network. This scheme has the following disadvantages: [0003] After the strokes are converted into standard fonts, they are stereotyped, lose the charm of "calligraphy", have no personality, and strokes that cannot be converted into standard fonts cannot be used; [0004] After the strokes are converted into images, they are merged with the background and cannot be edited in units of strokes. [0005] Therefore, it is necessary to provide a stroke-based encoding and decoding method, digitize the strokes, and transmit the strokes through the network to realize stroke-based network communication, so that each session e...
