Description
Technical field
The present invention relates to the computer graphical process field, especially relate to a kind of implementation method and system of original handwriting.
Background technology
Because touch pad being widely used in intelligent terminal, handwriting input become the main flow input of intelligent terminal gradually.The process that the handwriting input imitation is write at paper with pen uses finger or time writer to write on touch pad, can obtain the mark of expectation on electronic equipment.The information that touch pad passes to master processor is a series of coordinate sequence, and master processor is depicted as the coordinate sequence of input the process of mark of user expectation, and we are called former handwriting usually.
During former handwriting was used, the coordinate that touch pad passes to main frame generally was comprised of three parameter x, y and p.X and y have determined the positional information of handwriting tracks, and pressure p has been transmitted the tactile impressions information in the hand-written process.The drawing process of former person's handwriting track pattern, namely according to the (x of handwriting tracks, y), simulate continuous quantity with discrete magnitude, thereby produce a plurality of graphical pointvs, and take corresponding graphical pointv as starting point, in the track pattern of the crisscross filling certain width of hand-written front line direction, how wide concrete pattern fills is, determined by pressure p and corresponding simulation pen type, pressure is larger, and the filling width is larger.The breadth extreme of simulation pen type, the form of a stroke or a combination of strokes that can simulate as required (such as pencil, pen, writing brush etc.), concrete display screen and user's experience effect are surveyed front mensuration in advance.
Computer display is comprised of grid matrix, and the drafting essence of former person's handwriting track pattern is exactly to use the grid of its covering of color filling of setting in the zone that track covers.If the edges of regions that former person's handwriting track covers is tangentially inconsistent with transverse axis, Z-axis, the boundary line is drawn at screen and is out just had ladder so, sawtooth will appear in the graphic limit of drawing out, also be, (aliasing) loses shape, losing shape to refer in the raster plotter represents the distortion that continuous quantity causes with discrete magnitude, shown in following Figure 1A, the 1B.

Embodiment
Fig. 2 is the process flow diagram of the implementation method embodiment one of original handwriting of the present invention, and the implementation method of this original handwriting comprises:
S1. the trajectory coordinates of Real-time Collection handwriting, described trajectory coordinates comprises horizontal ordinate location parameter, ordinate location parameter and pressure parameter;
S2. horizontal ordinate location parameter and the ordinate location parameter according to Real-time Collection calculates movement velocity;
S3. determine the width of track drafting according to default pen type and the pressure parameter that gathers, and before track the track pattern of the crisscross filling respective width of line direction, and, when drawing the edge of described track pattern, dynamically adjust the quantity of pattern edge grid according to the movement velocity of calculating, and according to the quantity of described edge grid the edge of described track pattern is carried out anti-aliasing processing.
In the above-described embodiments, the trajectory coordinates that gathers is the sample sequence at a same time interval, can calculate Euclidean distance d between adjacent two coordinates according to following formula, wherein, and (x
1, y
1) and (x
2, y
2) be respectively the location parameter in two trajectory coordinates inputting continuously.
And, can be with the mean value of the Euclidean distance of the two adjacent coordinates of continuous a period of time as movement velocity.Through empirical statistics, relatively good as movement velocity with the mean value of 5 adjacent left and right sides Euclidean distances.Because: if the number of adjacent Euclidean distance is very little, often since some redundant coordinates of reporting of touch pad so that two adjacent coordinate points location overlaps, the movement velocity saltus step of calculating is more frequent, and speed is unstable, and is inconsistent with the situation of true hand-written motion; If the number of adjacent Euclidean distance is many, the delay that can cause again finding speed to change can not reacted the promptness that former handwriting movement velocity changes.
As previously mentioned, there is the place of ladder in the image border, if pattern edge is used for level and smooth grid quantity very little, graphing had obvious sawtooth.If but it is too much to be used for level and smooth grid quantity; the accuracy that former person's handwriting edge is drawn and the fluency of writing be influential (can not writing out such as writing very little word again; touch pad contact position and former person's handwriting track drawing position distance widen); quantity and the former person's handwriting edge-smoothing of level and smooth grid; write accuracy, the relation between the fluent writing as shown in Table 1:
Table one
Therefore, when anti-aliasing processing, but based on motion speed is dynamically adjusted the quantity of level and smooth grid.Hand-written when moving slowly, the variation curvature of movement locus is larger usually, and the user is higher to the pattern position attention rate of drawing, so the number of level and smooth grid reduces accordingly; Hand-written when moving soon, so the smaller user of variation curvature of handwriting tracks wants the higher smoothly corresponding increase of quantity of grid to contact position and drawing position apart from tolerance is also relative.Specifically can calculate according to formula 1 quantity of the corresponding edge of friction speed grid:
t=(v-v
min)/(V
max-v
min)
N
t=(1-t) * N
Min+ t*N
MaxFormula 1
Wherein, t is scale-up factor, and v is the movement velocity that step S2 calculates, v
MinBe the minimum speed under the set corresponding pen type, V
MaxBe the maximal rate under the set corresponding pen type, N
MinBe the minimum grid number under the set corresponding pen type, N
MaxBe the maximum grid number under the set corresponding pen type, N
tQuantity for the edge grid under the corresponding pen type that calculates.
And, in formula 1, the minimum value N of level and smooth grid
MinCan not less than 3, because can't realize color gradient less than the ladder of 3 grids, cannot eliminate sawtooth.The maximal value N of level and smooth grid number
MaxMeasure in advance according to selected different pen types and the density feature of display screen, this can not arrange very greatly such as the figure of simulating drafting pencil or pen, because the pencil pattern is thinner, former person's handwriting track is higher to position accuracy demand.According to the different qualities of display screen, maximal value is arranged to 4 or 5 usually; To thicker situations that draws a design such as writing brushes, the maximum number of level and smooth grid can be adjusted larger a little, because they will hang down a little to the susceptibility of drawing locus marginal position error, the maximum smoothly number of grid can be set to 8 or larger.Fig. 3 A, 3B be respectively the simulation pen writing " with " word and simulation brush writing " with " the test result figure of word.
Preferably, but the implementation method of original handwriting of the present invention also based on motion speed to the first stroke of a Chinese character and the vigour of style in writing when receiving control.After calculating former handwriting movement velocity, can be according to different touch pads, the different motion speed of writing determines the boundary value of judging the friction speed grade, the judgment basis that this speed class is processed as a follow-up receipts first stroke of a Chinese character vigour of style in writing.Table two is the movement velocity measured on touch pad and the measurement result of sport rank boundary value.
| Speed class | Very slow | Common writing | Comparatively fast write | Scribble fast |
| Movement velocity | 0～0.8 | 0.8～2.4 | 2.4～4.4 | 4.4～15 |
Table two
In the time of the general first stroke of a Chinese character, movement velocity is slow, will produce thick and heavy pen sense.When receiving pen, if movement velocity is slow, illustrates and write more steadily and surely, the vigour of style in writing should be thick and heavy; If write than comparatively fast, the vigour of style in writing should be elegant, and the tail end of writing is done elegant processing according to movement velocity, and speed is faster, and the vigour of style in writing is elegant more obvious.Control relation between speed class and the vigour of style in writing as shown in Table 3.
| Speed class | Very slow | Common writing | Comparatively fast write | Scribble fast |
| The vigour of style in writing is processed | Thick and heavy | Thick and heavy | Elegant | Very elegant |
Table three
About the thick and heavy processing of the vigour of style in writing, normally draw the wider a little circular pattern of conventional track width of ratio or other reticle pattern that configure in the place of movement locus.If at certain graphical pointv O
iThe place, the track drafting width that calculates according to default pen type and pressure parameter is r
iIf, do thick and heavy processing, can do suitable amplification correction according to the track drafting radius width of 2 pairs of these points of formula;
R
i'=К * R
iFormula 2
Wherein, wherein, R
iFor according to default pen type and determined this graphical pointv of the pressure parameter O that gathers
iThe width of the track drafting at place; R
i' for amplifying the width of revised track drafting; K is enlargement factor, and K〉1, and relevant with the pen type that sets, can get between 1.05 to 1.1 such as writing brush.For example, " in " word through the test result of the thick and heavy processing of the vigour of style in writing shown in Fig. 4 A.
About the elegant processing of the vigour of style in writing, suppose at graphical pointv P
i(x
i, y
i) locate to need to receive pen, this is put and previous graphical pointv P

i(x
i, y
i) be starting point, at θ
iDirection (be track before line direction) upward draw one and draw the continuity track that width narrows down to 1 pixel gradually.And the available formula 3 of the drafting length EL (Expand Length) of this continuity track calculates;
EL=(1-t)λ

i/Φ+tλ
2R
i/Φ
Wherein, EL is the length of continuity track; T is scale-up factor; λ

2Be constant, and λ
2λ
1, speed is faster like this, and EL is larger, and the vigour of style in writing that embodies is just more elegant; R
iBe the width according to default pen type and the determined track drafting of pressure parameter that gathers; Φ adjusts the factor, and 2＜Φ＜6, does corresponding adjustment according to the track drafting of different touch-screen density and different pen types, guarantees to prolong track both attractive in appearance, does not affect again the precision of actual track drafting.For example, " in " word through the test result of the elegant processing of the vigour of style in writing shown in Fig. 4 B.
Preferably, in the implementation method of original handwriting of the present invention, step S2 also comprises: calculate the angle changing of direction of motion according to the horizontal ordinate location parameter of Real-time Collection and ordinate location parameter, and whether identify current stroke according to the angle changing of described direction of motion be to roll over, collude, carry; Step S3 also comprises: when picture was rolled over, colluded, starts writing in drafting, the flex point of doubling, the picture that colludes, starts writing was carried out the mellow and full processing of the vigour of style in writing.In this embodiment, by judging the variation tendency of movement locus, sort out the motion flex point of former pen trace motion track, and increase the mellow and full vigour of style in writing processing of former person's handwriting in corner position, strengthen the aesthetic of former person's handwriting track.
Detect former pen trace motion variation tendency, also, the single change of coordinate on direction of motion or the variable quantity of accumulated change that detect follow-up input coordinate and input previously.As shown in Figure 5, move to the P3 point from the P1 point, movement direction angle has changed β, and we just can think that the movement locus variation tendency is β so, and unit is degree.If represent the vector of movement locus with polar coordinates (r, θ), the vector that P1P2 is corresponding is (d1, θ 1), the vector that P2P3 is corresponding (d2, θ 2), so β=θ 2 – θ 1.It should be noted that at this, can put P1(x1, y1 according to planimetric coordinates), P2 (x2, y2) with polar transformational relation, calculate first the tangent value tan θ 1=(y2-y1)/(x2-x1) of θ 1, calculate again the value of its arc-tangent value θ 1 according to the tangent value of θ 1.And, if absolute value | y2-y1| is far longer than absolute value | and x2-x1|, then cotangent value cot θ 1=(x2-x1)/(y2-y1) then calculates the value of its arc cotangent value θ 1 according to the cotangent value of θ 1.Similarly, available identical method calculates the value of θ 2.In addition, can stipulate the clockwise direction angle for just, counterclockwise angle is for negative.If double angle variable quantity symbol is consistent, the account for motion change direction is identical, otherwise, the motion change opposite direction.
Fig. 6 A-6F is the schematic diagram according to several situations of the angle changing identification stroke of direction of motion:
Situation 1: such as Fig. 6 A, the angle changing of two continuous flex points is all very little, and the direction of variation angle is consistent, this situation movement locus should be smooth motion, for example, writes " horizontal stroke ", " erecting ", " slash ", the basic stroke such as " right-falling stroke ", " O ", at this moment, flex point is not done particularization;
Situation 2: such as Fig. 6 B, the angle changing direction of two continuous flex points is just opposite, and to change angle be not very large, and the hand shake caused when this situation was generally write, and at this moment, flex point is not done special processing;
Situation 3: such as Fig. 6 C, the angle of flex point P2 changes β 1 near 90 degree, and the angle of flex point P3 variation β 2 is smaller, and this situation generally is identified as "fold" and draws, and at this moment, the P2 flex point need to be done mellow and full processing;
Situation 4: such as Fig. 6 D, the angle of flex point P2 changes β 1 about 145 degree, and the angle of flex point P3 variation β 2 is smaller, and this situation generally is identified as " colluding " and draws, and at this moment, the P2 flex point need to be done mellow and full processing;
Situation 5: such as Fig. 6 E, the angle of flex point P2 changes β 1 greater than 180 degree, and about 225 degree, and the angle of flex point P3 variation β 2 is smaller, and this situation generally is identified as " carrying ", and at this moment, the P2 flex point need to be done mellow and full processing;
Situation 6: such as Fig. 6 F, the angle of flex point P2 changes β 1 greater than 180 degree, and the angle of flex point P3 variation β 2 is smaller, and this situation generally is identified as " carrying " or " colluding ", and at this moment, the P2 flex point need to be done mellow and full processing;
Other situations are all pressed proper motion and are processed, and do not do special flex point and process.
About the mellow and full processing of the vigour of style in writing, the vigour of style in writing thick and heavy processing of the thick and heavy processing of the vigour of style in writing that can be when receiving during with the first stroke of a Chinese character superposes, thus the effect of inner round side side outside embodying.It should be noted that at this, but correction is amplified in the thick and heavy processing all width of 2 pairs of corresponding graphical pointvs of reference formula place track drafting, the thick and heavy processing difference of thick and heavy processing during the first stroke of a Chinese character when receiving only is that the enlargement factor of selecting is different, the corresponding enlargement factor of thick and heavy processing when the corresponding enlargement factor of thick and heavy processing when receiving generally speaking, is greater than the first stroke of a Chinese character.As shown in Figure 7, suppose at the P2 of track P1P2P3 point and need to realize the mellow and full vigour of style in writing, so at first receive a vigour of style in writing in thick and heavy circle of P2 point-rendering, shown in regional A1, guarantee like this in the outside of flex point it is round and smooth effect, be plotted to again P3 motion of point track take the P2 point as starting point, shown in regional A2.Because the track that the track that P2 point and P3 are ordered and P1 point are ordered to P2 has overlapping part, this part inboard effect that overlaps on flex point is exactly square effect.
