Embodiment

In order to make the purpose, technical scheme and advantage of the disclosure clearer, the disclosure is made below in conjunction with attached drawing into One step it is described in detail, it is clear that described embodiment is only disclosure part of the embodiment, rather than whole implementation Example.Based on the embodiment in the disclosure, what those of ordinary skill in the art were obtained without making creative work All other embodiment, belongs to the scope of disclosure protection.

With the development of display technology, more and more terminals are provided with paintbrush function.There is the terminal energy of paintbrush Enough slides according to for display screen, display are used for the figure for characterizing the sliding trace of the slide.It is exemplary, the pin Slide to display screen can be：For the touch-control slide of touching display screen, alternatively, by mouse on a display screen Slide.

Fig. 1 is according to a kind of method flow diagram of sliding trace display methods of exemplary embodiment offer, the slip Track display method can be used for terminal.As shown in Figure 1, the sliding trace display methods can include：

In a step 101, according to a slide for display screen, the cunning for characterizing slide is determined successively Multiple points of dynamic rail mark.

In the embodiments of the present disclosure, " point " refers to the point on display screen with position feature, its position feature can be adopted With the coordinate representation in the preset coordinate system on display screen.

In a step 102, determine each to put corresponding sliding speed in multiple points.

In step 103, the figure of sliding trace is shown, the change of the width of the figure of sliding trace is corresponding with multiple points Sliding speed change it is negatively correlated.

The figure of the sliding trace refers to the figure for the form for reflecting the sliding trace.

In conclusion in the sliding trace display methods provided due to the embodiment of the present disclosure, it is previously determined at least one Corresponding sliding speed is each put in point, and then when according to the figure for each putting corresponding sliding speed display sliding trace, Enable to the change of the change sliding speed corresponding with multiple points of the width of the figure of the sliding trace negatively correlated, so that Figure and the user of sliding trace to slide on paper obtained figure using pen more similar, so, the figure of sliding trace The display effect of shape is distinguished smaller with hand-written effect.

Fig. 2 is according to the method flow diagram of another sliding trace display methods of exemplary embodiment offer, the cunning Dynamic track display method can be used for terminal.As shown in Fig. 2, the sliding trace display methods can include：

In step 201, after width instructions are received, the target trajectory width indicated by width instructions is obtained.

When user needs the paintbrush function in using terminal, user can set operation in the enterprising line width of terminal, with Triggering terminal generation is instructed for indicating that the width of target trajectory width is set, and is obtained the width and set indicated by instruction Target trajectory width.It that is to say, user needs to set the target trajectory width of paintbrush in terminal.

In step 202, according to a slide for display screen, the cunning for characterizing slide is determined successively Multiple points of dynamic rail mark.

Terminal can carry out one-time detection every preset time period to display screen, to determine to be directed to display screen in each detection The corresponding point of operation.During user carries out a slide for display screen, terminal can carry out display screen Multiple touch point collection is with the corresponding z point of the definite slide, z >=1, when this z point is continuous z collection in sequential Point determined by quarter.It should be noted that terminal can record this point on a display screen in each point in determining z point Coordinate in preset coordinate system, and the coordinate of z point can be according to time order and function sequential storage.

When a slide for display screen is the touch-control slide for touching display screen, user is for aobvious During slide of display screen, touch control object (such as finger or stylus) can be pressed touch-control successively and shown by user Screen, slide on touching display screen and lift touch control object from touching display screen.In this process, what terminal determined should The corresponding z point of slide includes：The initial point determined when touch control object is pressed touching display screen, the position with the initial point Identical point, and start position changes first after slide point and its point afterwards.

When a slide for display screen is by mouse slide on a display screen, user is for aobvious During slide of display screen, user can control mouse to click on display screen successively, clicking on the state of display screen Under slide on a display screen and stop click on display screen.In this process, the slide that terminal determines is z corresponding Point includes：Mouse clicks on the initial point determined during display screen, the point identical with the position of the initial point, and starts slide The point and its point afterwards that position changes first afterwards.

The point that terminal can by the point of position change first after beginning slide and its afterwards in step 202, is determined as Multiple points for the sliding trace for characterizing slide.It should be noted that the z point that terminal determines under normal conditions can be with Including a point identical with the position of the initial point, it is usually the case that sliding trace for characterizing slide is more A point is the point after second point in z point.

In step 203, determine each to put corresponding sliding speed in multiple points.

Corresponding sliding speed is each put in multiple points is：The slip that the upper point each put each is put to this Speed.Terminal is after each point is determined, it is possible to determines that this each puts corresponding sliding speed.It should be noted that should A upper point for first point in multiple points is：A upper point for the point in z point.Assuming that z point includes：Initial point, A point identical with initial point position and multiple points of the sliding trace for characterizing slide, then in the plurality of point A upper point for one point is a point identical with initial point position.Assuming that i >=2, i-th point in the plurality of point upper One point is：The i-th -1 point in the plurality of point.

Exemplary, terminal is after i-th point in determining multiple points, it is possible to obtains the in and multiple points at i-th point The coordinate of i-1 point, and obtain determine i-th point and the i-th -1 point time, and then according to i-th point of coordinate, i-th - The time of the coordinate of 1 point, the time for determining at i-th point and definite the i-th -1 point determines i-th point of corresponding slip speed Degree.Wherein, i-th point of corresponding sliding speedd_(i-1,i)For i-th point and the distance of the i-th -1 point, t_(i-1,i) To determine the absolute value of the time difference of and the i-th -1 point at i-th point.

For example, it is assumed that d_(i-1,i)About 71.81010064149748 unit lengths (such as the corresponding length of a pixel For a unit length), t_(i-1,i)For 17 milliseconds, then i-th point of corresponding sliding speed be about 4.2241235 unit lengths/ Millisecond.

In step 204, corresponding sliding speed is each put according in target trajectory width and multiple points, determined multiple Corresponding track width is each put in point.

It should be noted that each putting corresponding track width each puts corresponding sliding speed negative correlation with this, and should Each put corresponding track width and target trajectory width positive correlation.It that is to say, when user is faster in the sliding speed of some point When, the corresponding track width of point is smaller, and when user is slower in the sliding speed of some point, which gets over Greatly.

Optionally, Fig. 3 is a kind of method flow diagram of the definite track width provided according to an exemplary embodiment.w≥ 1, w-th point in multiple points is any one point in multiple points, in Fig. 3 will with determine in multiple points w-th point it is corresponding Exemplified by track width, step 204 is explained.As shown in figure 3, step 204 can include：

In step 2041, the corresponding maximum width of target trajectory width and most is determined according to default width correspondence Small width.

Width correspondence can be preset with terminal, which can include at least one track width pair The maximum width and minimum widith answered, and track width corresponding maximum width and minimum widith in the width correspondence Equal positive correlation.Terminal is after definite target trajectory width, it is possible to according to the default width correspondence, determines the target track The corresponding maximum width of stitch width and minimum widith.

In step 2042, determine that formula determines w-th point of corresponding reference width according to reference width.

W-th point of corresponding reference width in the plurality of point is L_cw, which determines that formula is

L_maxFor the corresponding maximum width of target trajectory width, L_minFor target trajectory The corresponding minimum widith of width, V_wFor the w-th point of corresponding sliding speed, V_yTo preset sliding speed.Exemplary, this is default Sliding speed can be 4 unit lengths/millisecond.

If formula is determined according to the reference width it is known that V_wMore than V_y, then L_cwIt is less than L_min；If V_wIt is equal to V_y, then L_cwIt is equal to L_min；If V_wLess than V_y, and V_wMore than zero, then L_cwIt is greater than L_min；If V_wIt is zero, then L_cwJust Equal to L_max。

In step 2043, by the corresponding minimum widith of target trajectory width and w-th point of corresponding reference width most Big width, is determined as w-th point of corresponding expected width.

Terminal is in the corresponding minimum widith of definite target trajectory width, can be with and after w-th point of corresponding reference width Compare the size of the minimum widith and the reference width, and the minimum widith and width maximum in the reference width are determined as W-th point of corresponding expected width.

It should be noted that terminal, after w-th point of corresponding expected width is determined, terminal also needs to judge at w-th point Whether meet the first preset condition, and judge whether meet the second preset condition at w-th point.Wherein, the first preset condition can With including：W-th point is first point in multiple points, and this slide be after receiving width and instruction be set the Slide；Second preset condition can include：W-th point is the point after first point in multiple points.

In step 2044, when meeting the first preset condition at w-th point, determine that w-th point of corresponding expected width is W-th point of corresponding track width.

It is first point in multiple points when w-th point, and this slide is after receiving width and setting instruction First time slide when, terminal can determine that w-th point of corresponding expected width is w-th point of corresponding track width. At this time, the w-th point of corresponding track width sliding speed corresponding with w-th point that terminal is determined is negatively correlated.

In practical application, when meeting the first preset condition at w-th point, terminal can also be to first point in step 2044 Corresponding expected width is handled, such as the corresponding expected width of first point add, subtracted, multiplied and except at least one of Computing.Afterwards, terminal may determine that the corresponding expected width of first point after processing, should whether in the range of predetermined width The upper limit of predetermined width scope is less than the corresponding maximum width of target trajectory width, and the lower limit of predetermined width scope is more than target track The corresponding minimum widith of stitch width.If the result of above-mentioned judgement is：The corresponding expected width of first point after processing is positioned at pre- If in width range, then terminal can be directly corresponding as first point using the corresponding expected width of first point after processing Track width；If the result of above-mentioned judgement is：The corresponding expected width of first point after processing is located at outside predetermined width scope, Then terminal can take a width at random as the corresponding track width of first point directly in the range of predetermined width.

In step 2045, when meeting the second preset condition at w-th point, determine that formula determines w according to the first width The corresponding track width of a point.

Wherein, i-th point of corresponding track width in multiple points is G_i, i >=2, the first width determines that formula is：

＆ represent and, G_i-1For the corresponding track width of the i-th -1 point, Y_iFor i-th point of corresponding expected width, i-th Point is i-th point of corresponding distance with the distance of the i-th -1 point, and i-th point of corresponding expected width is corresponding with the i-th -1 point The absolute value of the difference of track width is i-th point of corresponding absolute value, Z_iFor in i-th point of corresponding distance and absolute value Minimum value.

It that is to say, be the point (such as during w=2) in multiple points after first point when w-th point, terminal can determine the W point meets the second preset condition, and according to w-th point of track width corresponding with the distance of the w-1 point, the w-1 point, W-th point of corresponding expected width and the first width determine formula, determine the w-th point of corresponding track width.At this time, eventually The w-th point of corresponding track width determined and target trajectory width positive correlation, sliding speed corresponding with w-th point is held to bear Correlation, and track width corresponding to the w-1 point is related.

In step 2046, when being unsatisfactory for the first preset condition and the second preset condition at w-th point, determine at w-th point Corresponding expected width is last corresponding track width of point for characterizing the sliding trace of last slide.

It is first point (namely w=1) in multiple points when w-th point, and this slide is not to receive width When degree sets the first time slide after instruction, terminal can determine that be unsatisfactory for the first preset condition and second pre- at w-th point If condition.At this time, terminal can obtain last corresponding rail of point of the sliding trace for characterizing last slide Stitch width, and determine that last puts corresponding track width to w-th point of corresponding track width for this.

In practical application, in first corresponding track width of point in determining multiple points, this cunning can not also be judged It is dynamic operation whether be receive width set instruction after first time slide, but directly execution step 2044.

In step 205, the sliding type each put in multiple points is determined.

Terminal is after determining at w-th point, it is possible to obtains w-th point of coordinate and the seat of the w-1 point in multiple points Mark, and then w-th point of sliding type is determined according to w-th point of coordinate and the coordinate of the w-1 point.

Wherein, w-th point and the w-1 point abscissa distance be more than ordinate apart from when, w-th point of slip side Formula is slides laterally mode (namely for tend to slide laterally caused point on a display screen) at w-th point, at w-th point and the W-1 point in preset coordinate system abscissa distance be less than or equal to ordinate apart from when, w-th point of sliding type is vertical To sliding type (namely w-th point is to tend to point caused by longitudinal sliding motion on a display screen).

For example, it is assumed that coordinate of the w-1 point in preset coordinate system is (1,2), w-th point in preset coordinate system Coordinate is (3,3), then terminal can determine that the abscissa distance of w-th point and the w-1 point is 2, and w-th point a with w-1 The ordinate distance of point is 1, namely the abscissa distance of w-th point and the w-1 point is more than ordinate distance, and terminal can at this time To determine w-th point of sliding type as in a manner of sliding laterally.

Assuming that coordinate of the w-1 point in preset coordinate system is (1,2), the w-th point of coordinate in preset coordinate system For (2,4), then terminal can determine that the abscissa distance of w-th point and the w-1 point is 1, w-th point with the w-1 point Ordinate distance is 2, namely the abscissa distance of w-th point and the w-1 point is less than ordinate distance, and terminal can be true at this time Sliding type w-th point fixed is longitudinal sliding motion mode.

In step 206, according to each putting corresponding track width in multiple points, and the slip side of each target point Formula, shows the figure of sliding trace.

Optionally, the point in the plurality of point in addition to first point can be determined as target point by terminal.It is namely multiple Target point in point includes at j-th point in multiple points, j >=2.Terminal can according to the corresponding track width of each target point, The each upper corresponding track width of a point of target point and the sliding type of each target point, show that each target point corresponds to Quadrangle.Wherein, j-th point of a upper point is -1 point of jth in multiple points, and j-th point of corresponding quadrangle includes： Be parallel to each other and opposite first while and when second, -1 point of jth is located at the midpoint on the first side, and j-th point positioned at the second side Midpoint, the length on the first side are equal to the corresponding track width of -1 point of jth, and the length on the second side is equal to j-th point of corresponding rail Stitch width.

Fig. 4 is a kind of schematic diagram of the j-th point of corresponding quadrangle provided according to an exemplary embodiment, such as Fig. 4 institutes Show, j-th point of corresponding quadrangle includes：Be parallel to each other and opposite first in B1 and second B2, -1 point of jth is positioned at the The midpoint of one side B1, the j-th point of midpoint for being located at the second side B2, the length of the first side B1 are equal to the corresponding track of -1 point of jth Width, the length of the second side B2 are equal to j-th point of corresponding track width.

It should be noted that when j-th point of sliding type is slides laterally mode, j-th point of corresponding quadrangle First in B1 and second axis of ordinates Ys of the B2 each parallel to preset coordinate system；It is longitudinal direction in j-th point of sliding type During sliding type, j-th point of corresponding quadrangle first in B1 and second horizontal seats of the B2 each parallel to preset coordinate system Parameter X.In Fig. 4 by taking j-th point of sliding type is in a manner of longitudinal sliding motion as an example.

Shown in terminal when finishing the corresponding quadrangle of each target point, all quadrangles composition that terminal is shown slides rail The figure of mark, at this time, the plurality of point are respectively positioned in the figure of sliding trace, and each in the plurality of point in the figure of sliding trace The width of point position is equal to this and each puts corresponding track width (namely each point place of this in quadrangle where each point The length on side).

For example, Fig. 5 is a kind of principle schematic of the figure of display sliding trace according to an exemplary embodiment, Glide direction at this time is direction F1 as shown in Figure 5, and terminal shows each corresponding quadrangle of target point in multiple points, and And the plurality of point is located on the side of these quadrangles, but initial point is not in these quadrangles.

Step 207, when multiple points include cross-goal point, the corresponding square of display cross-goal point, wherein, it is multiple Point includes next point of cross-goal point, and the slip of the sliding type of cross-goal point and next point of cross-goal point Mode is different.

Optionally, terminal is after the corresponding quadrangle of each target point is shown, if multiple points include the next of the target point It is a, then it may determine that whether the sliding type of the target point is identical with the sliding type of its next point, and in the target point Sliding type it is different from the sliding type of its next point when, it is cross-goal point to determine the target point, and shows intersection mesh The corresponding square of punctuate.Wherein, the corresponding four square vertex of cross-goal point include：Cross-goal point corresponding four Two ends on the first side in two endpoints when second in shape, and the corresponding quadrangle of next point of cross-goal point Point.

Fig. 6 is a kind of j-th point corresponding square schematic diagram provided according to an exemplary embodiment.Terminal is aobvious After showing the corresponding quadrangle of+1 point of jth, as shown in fig. 6, the sliding type for working as at j-th point is longitudinal sliding motion mode, jth+1 The sliding type of point shows j-th of target point for when sliding laterally mode, then terminal determines that be cross-goal point at j-th point Corresponding square.Wherein, this j-th point corresponding four square vertex include：In j-th point of corresponding quadrangle Two the endpoints D1 and D2 on two sides, and in the corresponding quadrangle of+1 point of jth the first side two endpoints D3 and D4.Namely It is that the place that sliding type switches in the figure of sliding trace can there are triangle white space K, terminal can show jth A point is corresponding square to make up triangle white space K, so that multiple quadrangle energy in the figure of sliding trace Enough gentle transition.

Optionally, the embodiment of the present disclosure is with when multiple points include cross-goal point, terminal shows that cross-goal point corresponds to Square exemplified by.In practical application, terminal can also show that cross-goal point corresponds to when multiple points include cross-goal point Right angled triangle.At this time, three vertex of the j-th point of corresponding right angled triangle include：J-th point, j-th point of correspondence Quadrangle in the second side an endpoint, and in the corresponding quadrangle of+1 point of jth the first side an endpoint, and right angle Any point in triangle is located at outside j-th point of corresponding quadrangle and the corresponding quadrangle of+1 point of jth.

In a step 208, determine next point of cross-goal point and a upper point be cross-goal point comparison point.

Last point of terminal in the plurality of point is determined, and show the corresponding quadrangle of each target point, and After the corresponding square of cross-goal point, it may be determined that next point of cross-goal point and a upper point are the cross-goal The comparison point of point.Please continue to refer to Fig. 6, j-th point is a cross-goal point, and terminal can be by -1 point of jth and jth+1 Point is determined as j-th point of comparison point, namely determines that each point adjacent with cross-goal point is the cross-goal point Comparison point.

In step 209, will be identical with the coordinates of targets of the cross-goal point in the corresponding square of cross-goal point In vertex, the close vertex of each comparison point of the cross-goal point is determined as the datum vertex of each comparison point.

Wherein, when the sliding type of each comparison point is slides laterally mode, coordinates of targets is in preset coordinate system Ordinate, when the corresponding sliding type of each comparison point is longitudinal sliding motion mode, coordinates of targets is in preset coordinate system Abscissa.Terminal is it needs to be determined that the datum vertex of each comparison point.

Please continue to refer to Fig. 6, j-th point of corresponding square has four vertex, is respectively D1, D2, D3 and D4.This four The abscissa of D1 and D2 in a vertex are identical with j-th point of abscissa, D3 and the ordinate of D4 and j-th point of ordinate It is identical.When comparison point for jth -1 when, if the sliding type of -1 point of jth is longitudinal sliding motion mode (as shown in Figure 6), Terminal can be using the reference in the D1 and D2 in this four vertex close to the vertex (such as D1) of -1 point of jth as -1 point of jth Vertex.In addition, if the sliding type of -1 point of jth is slides laterally mode, terminal can by the D3 in this four vertex and Close to datum vertex of the vertex of -1 point of jth as -1 point of jth in D4.

It should be noted that when comparison point for jth+1 when terminal determine+1 point of jth datum vertex process, May be referred to when comparison point for jth -1 when terminal determine -1 point of jth datum vertex process, the embodiment of the present disclosure exists This is not repeated.

In step 210, determine identical with the sliding type of each comparison point in multiple points and continuous at least one Point is traveled through, wherein, at least one traversal point includes each comparison point and does not include each cross-goal point, and at least one The coordinates of targets for traveling through point is arranged successively along the direction of the coordinates of targets away from cross-goal point.

After the datum vertex of+1 point of jth is determined, terminal can judge in multiple points successively since+1 point of jth Whether+1 point of jth and each point after it meet at least one first condition in three first conditions.It is exemplary, this Three first conditions can include：(1) point currently judged is last point in multiple points；(2) multiple points include jth+1 Point after a point, and when the point after+1 point of jth in multiple points judges, the sliding type of the point currently judged and The sliding type of j+1 point is different；(3) multiple points include the point after+1 point of jth, and+1 point of jth in multiple points When point afterwards judges, the coordinates of targets of the point currently judged and the coordinates of targets of cross-goal point are all higher than judgement The coordinates of targets of point, or the coordinates of targets of the coordinates of targets of the point currently judged and cross-goal point are respectively less than a judgement Point coordinates of targets, or the point currently judged coordinates of targets be equal to upper one judgement point coordinates of targets.

When some point meets at least one first condition in three first conditions, terminal can stop to jth+1 Point and its point afterwards are judged, and will currently have determined the condition (2) being unsatisfactory in these three first conditions and bar The point of part (3) is as at least one traversal point.So that slip side of the sliding type of each traversal point with+1 point of jth Formula is identical, and at least one traversal point is continuous, and the coordinates of targets of these traversal points is more and more far away from cross-goal point Coordinates of targets.

After the datum vertex of -1 point of jth is determined, terminal can judge in multiple points successively since -1 point of jth Whether -1 point of jth and each point before it meet at least one second condition in three second conditions.It is exemplary, this Three second conditions can include：(1) point currently judged is first point in multiple points；(2) multiple points include jth -1 Point before point, the and when point before -1 point of jth in multiple points judges, the sliding type and jth of the point currently judged - The sliding type of 1 point is different；(3) multiple points include -1 point of jth before point, and in multiple points -1 point of jth it When preceding point judges, the coordinates of targets of the point currently judged and the coordinates of targets of cross-goal point are all higher than a point judged Coordinates of targets, or the coordinates of targets of the coordinates of targets of the point currently judged and cross-goal point be respectively less than one judgement Point coordinates of targets, or the point currently judged coordinates of targets be equal to upper one judgement point coordinates of targets.

When some point meets at least one second condition in three second conditions, terminal can stop to jth -1 Point and its point before are judged, and will currently have determined the condition (2) and condition being unsatisfactory in three second conditions (3) point is as at least one traversal point.The sliding type of each traversal point is identical with the sliding type of -1 point of jth, and At least one traversal point is continuous, and the coordinates of targets of these traversal points is more and more far away from the coordinates of targets of cross-goal point.

In step 211, the coordinates of targets of cross-goal point is respectively positioned on being somebody's turn to do in the coordinates of targets of at least one traversal point When between the coordinates of targets of the datum vertex of each comparison point, the target time of each comparison point at least one traversal point is determined Go through a little.
