Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
Fig. 1 is a kind of stroke synchronous method that the embodiment of the present invention provides, and the method comprises the following steps.
S101, obtains the dot information of writing of the first predetermined number, writes dot information and comprises and write the stroke mark of a place stroke and write a little coordinate of the pixel of correspondence on screen.
First terminal, according to user's mouse or gesture operation, is recorded writing a little on screen.Often record writing a little of some, be just packaged as an instruction and send, thereby the handwriting data that whole writing process is produced becomes fluidized state.
The quantity of writing that every instruction comprises arranges in advance in system.First terminal obtains the dot information of writing of the first predetermined number, and this is write dot information and comprises the stroke mark of writing a place stroke, and writes the some pixel coordinate of correspondence on screen.This stroke mark comes from middle control end, is used for identifying this and writes a little affiliated stroke.By first terminal, by recording user, the operation of writing on screen obtains this pixel coordinate.
For example, this first predetermined number to write dot information as follows:
{″Offset″：0，″OP″：0，″Data″：″[{\″Index\″：-516824730，\″Points\″：[{\″X\″：628.66，\″Y\″：356.37}，{\″X\″：601.09，\″Y\″：360.87｝，{\″X\″：571.07，\″Y\″：366.43}，{\″X\″：505.39，\″Y\″：383.12}，{\″X\″：471.52，\″Y\″：395.96}，{\″X\″：438.8，\″Y\″：414.29}，{\″X\″：408.29，\″Y\″：432.85}，{\″X\″：381.62，\″Y\″：453.14}，{\″X\″：359.37，\″Y\″：473.84}，{\″X\″：342.61，\″Y\″：494.2}，{\″X\″：330.58，\″Y\″：513.0}，{\″X\″：323.55，\″Y\″：529.95}，{\″X\″：320.44，\″Y\″：544.35}，{\″X\″：320.36，\″Y\″：554.16}，{\″X\″：322.48，\″Y\″：564.63}，}\″X\″：326.0，\″Y\″：574.04}]}]″，″InkStartData″：null，″UID″：-963320124，″TID：2，″From″：″831″}
Wherein, the order of Offset presentation directives; OP has 5 values, 0 (writing state), 1 (stroke is wiped in expression), 2 (wiping all person's handwritings), 3 (convergent-divergents), 4 (notice has handwriting information midway); Data is the set of stroke; Points is the set of point, and the value of the inside represents respectively X-axis a little and the coordinate of Y-axis, and Index is that stroke identifies.InkStartData and UID are used as other; TID has three values: 0 (fluidisation finishes), 1 (fluidisation starts), 2 (fluid mapper processes); From represents the source terminal that comes of this instruction.
S102, dot information to the second terminal of writing that sends the first predetermined number is carried out simultaneous display.
First terminal is packaged as the dot information of writing of the first predetermined number of record an instruction and is sent to the second terminal, carries out simultaneous display for the second terminal.
First terminal is cut apart whole writing process according to a quantity of writing of record, the dot information of writing of every record the first predetermined number is just packaged as an instruction and is distributed to each the second terminal, thereby realized the fluidization treatment of the data of identifying the handwriting, make each second terminal can with first terminal simultaneous display written handwriting.
In an embodiment of the present invention, writing each in dot information, to write a little corresponding pixel on screen be multiple.For the ease of eye recognition and embody the thickness of stroke, each to write a little corresponding writing on screen be a little multiple, makes the bandwagon effect of written handwriting better and be convenient to eye recognition.
In an embodiment of the present invention, write dot information also comprise write some pixel corresponding on screen pressure sensitivity parameter, write any one or more parameter in color parameter, the thickness parameters of a place stroke.
This pressure sensitivity parameter embodies the writing physical strength of user at each pixel of screen, and can be used for the written handwriting of each pixel to carry out the processing of vigour of style in writing effect.
This color parameter represents to write a color for place stroke, and first terminal and the second terminal show corresponding stroke according to this color parameter.
This thickness parameters represents to write a default line weight of place stroke, in conjunction with pressure sensitivity parameter, the local thickness of written handwriting lines is done to further adjustment.
For example, writing of can being illustrated above adds above-mentioned pressure sensitivity parameter, color parameter and thickness parameters in dot information.
