Referring to fig. 1, fig. 1 is a schematic flow chart illustrating an electronic stroke error correction method according to an embodiment of the present invention. The electronic stroke error correction method provided by the embodiment of the invention can be applied to electronic equipment with a touch screen, and can correct the finished strokes, so that the finally reflected strokes meet the requirements of users. As shown in fig. 1, the method includes steps S110 to S160.
S110, acquiring a pen state value of an initial pen-dropping point, confirming a stroke weight corresponding to the pen state value of the initial pen-dropping point in a preset stroke weight library according to the pen state value of the initial pen-dropping point, and setting the stroke weight as the initial stroke weight.
In the embodiment of the invention, when a user writes electronically, the user usually writes on the touch screen through the touch pen, and the corresponding device displays the strokes written by the user in the preset display area. For a single character, the stroke sequence of electronic writing is the same as the stroke sequence of actual writing, for example, for a "king" character, a user will write a horizontal first, when writing a horizontal, the writing for a horizontal is generally completed at one time, and the initial pen-drop point refers to the pen-drop point when the user writes a horizontal, correspondingly, when the user completes the writing for a horizontal and lifts the pen, there will be a corresponding ending pen-drop point, for a "king" character, the "king" character includes four strokes, and therefore, generally, four initial pen-drop points and four ending pen-drop points are included, wherein, the error correction process for each stroke is the same, and only one stroke is written as an example to be described below.
When a user starts to write a stroke, an initial stroke falling point of the stroke is obtained, and an initial stroke weight corresponding to the initial stroke falling point is confirmed in a preset stroke weight library according to a pen state value of the initial stroke falling point, wherein the stroke falling point refers to a point on a touch screen where the user is sensitive to writing, generally, the pen state value is judged according to a contact area between the pen and the touch screen, the contact area can be divided, different intervals correspond to different pen state values, for example, the contact area is 1 square millimeter, the pen state value can be 10, and a number 5 font is corresponding to a range from 10 to 20 in the preset stroke weight library, or each pen state value can correspond to one stroke weight.
And S120, drawing a line according to the thickness of the initial stroke, and recording the pen state value of each pen point in the line drawing process.
In the embodiment of the invention, the user generally continues writing, so after the initial stroke weight is confirmed, the line is drawn according to the initial stroke weight, the stroke written by the user is displayed on the display screen, and simultaneously, the pen state value of each pen point in the line drawing process is recorded while the line is drawn.
In some embodiments, for example, in this embodiment, the step S120 may include the following steps: acquiring a pen moving mode selected by a user, wherein the pen moving mode comprises a pen moving mode and a conventional pen moving mode; if the pen-moving mode is the pen-moving mode, recording the thickness value of each pen-falling point and the speed value between adjacent pen-falling points, and taking the thickness value as the pen state value and the speed value as an adjustment value; and if the pen moving mode is the conventional pen moving mode, recording the thickness value of each pen falling point, and taking the thickness value as the pen state value.
In the embodiment of the invention, the pen moving mode can be generally divided into a pen moving mode and a conventional pen moving mode, the pen moving mode refers to that the thickness of the strokes is correspondingly changed in the same stroke, so that the strokes have water caltrops, and the stroke thicknesses of the conventional pen moving mode are the same. When writing, the user can select whether to carry out the pen-tip pen-moving or the conventional pen-moving in advance, so that the pen-moving mode selected by the user can be obtained. When the pen-moving mode selected by the user is pen-moving by front, the thickness value of each pen-falling point and the velocity value between adjacent pen-falling points need to be recorded, and the thickness value and the velocity value are respectively stored, for example, a time interval from when the user writes is sensed from a first pen-falling point to when the user writes is sensed from a second pen-falling point, and the distance from the first pen-falling point to the second pen-falling point is divided by the time interval to obtain the velocity value from the first pen-falling point to the second pen-falling point. And then, taking the thickness value as a pen state value and the speed value as an adjusting value, and adjusting the thickness of the stroke between each pen point through the adjusting value after the current stroke is completed, for example, the faster the speed between adjacent pen points is, the thinner the stroke is, and the slower the speed is, the thicker the stroke is. When the pen-moving mode selected by the user is the conventional pen-moving mode, the thickness value of each pen-falling point is recorded and serves as the pen state value.
And S130, confirming a reference interval between the initial pen-down point and the current pen-down point according to a preset rule.
In the embodiment of the invention, writing of a user is generally continuous, so that the method provided by the invention is used for acquiring the pen state value of each pen point in real time, when the reference interval is confirmed, the reference interval is confirmed between the initial pen point and the current pen point, if the stroke is short or the current pen point is closer to the initial pen point, the reference interval is not acquired, and the line is drawn by using the thickness of the initial stroke until the rule of acquiring the reference interval is met.
In some embodiments, for example, in this embodiment, the step S130 may include the following steps: judging whether the number of pen falling points between the initial pen falling point and the current pen falling point is greater than or equal to a second preset number M or not; if the number of the stroke falling points between the initial stroke falling point and the current stroke falling point is less than the second preset number M, drawing a subsequent stroke by using the thickness of the initial stroke falling point; if the number of the pen-down points between the initial pen-down point and the current pen-down point is greater than or equal to the second preset number M, continuously selecting M pen-down points between the initial pen-down point and the current pen-down point; and taking the interval formed by the selected pen-down points as the reference interval.
In the embodiment of the present invention, the second preset number M is specified by the user, for example, 10, it is determined whether the number of the stroke falling points between the initial stroke falling point and the current stroke falling point is greater than 10 and less than 10, the subsequent stroke is drawn with the initial stroke thickness, and if the number is not less than 10, the requirement of obtaining the reference interval is met, and then 10 stroke falling points are continuously selected as the reference interval. In general, 10 pen-down points are sequentially selected from the initial pen-down point, or any 10 continuous pen-down points may be selected.
And S140, judging whether the pen state values of all the pen falling points in the reference interval are the same.
In the embodiment of the present invention, the reference interval includes a plurality of pen-down points and pen state values corresponding to the pen-down points, and it needs to further determine whether the pen state values of all the pen-down points in the reference interval are the same.
In some embodiments, for example, in this embodiment, the step S140 may be followed by the following steps: if the pen state value of at least one pen point in the reference interval is different from the pen state values of the rest pen points, determining a next reference interval between the initial pen point and the current pen point, and returning to the step of judging whether the pen state values of all the pen points in the reference interval are the same, wherein the pen points in any two reference intervals are not repeated; and if the number of the selected reference intervals is larger than a first preset number N, drawing subsequent strokes according to the initial stroke thickness.
In the embodiment of the present invention, when the pen status value of at least one pen drop point in the reference interval is different from the pen status values of other pen drop points, the next reference interval may be continuously determined according to the preset rule, where the pen drop points included in any two reference intervals are different, for example, 50 pen drop points are included in total from the initial pen drop point to the current pen drop point, 10 pen drop points may be selected from the initial pen drop point as the reference interval, and if the currently selected reference interval does not satisfy the requirement, 10 pen drop points are continuously selected from the eleventh pen drop point as the reference interval until the selected reference interval satisfies the requirement. When the number of the selected reference intervals is larger than the first preset number N, for example, larger than 4, it is indicated that the floating change of the contact area between the pen and the touch screen is large when the user writes, and the stroke weight required by the user cannot be accurately determined, so that the subsequent strokes can be completed by using the initial stroke weight, and under the normal condition, the initial stroke weight can reflect the stroke weight desired by the user.
And S150, if the pen state values of all the pen-falling points in the reference interval are the same, taking the pen state value in the reference interval as a reference pen state value, and determining the stroke weight corresponding to the reference pen state value in the preset stroke weight library.
In the embodiment of the present invention, when the pen state values of all pen-falling points in the reference interval are the same, the pen state value in the reference interval may be used as the reference pen state value, and the stroke weight corresponding to the reference pen state value is determined in the preset stroke weight library. When the pen state values of all the pen falling points in a certain reference interval are the same, the reference interval can accurately reflect the stroke weight desired by the user.
In some embodiments, for example, in this embodiment, the step S150 may include the following steps: if the pen-moving mode is the pen-moving mode, calculating a pen-tip thickness value between adjacent pen-falling points according to the thickness value and the speed value in the reference pen state value, and confirming the stroke thickness corresponding to the pen-tip thickness value in the preset stroke thickness library; and if the pen moving mode is the conventional pen moving mode, confirming the stroke weight corresponding to the thickness value in the preset stroke weight library according to the thickness value in the reference pen state value.
In the embodiment of the present invention, the contents of the pen state values of the pen-tip-moving pen and the conventional pen-moving pen are different, and therefore, when the reference pen state value is confirmed, the pen-moving mode selected by the user needs to be confirmed first. When the pen movement mode selected by the user is pen movement by the pen nib, the pen nib thickness value is calculated according to the thickness value and the speed value of the adjacent pen falling point, wherein the pen nib thickness value is inversely proportional to the speed value, the faster the speed is, the smaller the pen nib thickness value is, the thinner the corresponding stroke thickness is. When the pen-moving mode selected by the user is the conventional pen-moving mode, the thickness of the stroke is confirmed according to the thickness value.
And S160, redrawing the finished stroke and continuing to draw the subsequent strokes according to the stroke weight corresponding to the reference stroke state value.
In the embodiment of the present invention, after the reference pen state value is confirmed, the previously completed stroke may be redrawn according to the stroke weight corresponding to the reference pen state value, and if the user is still writing the current stroke, the subsequent stroke is drawn with the stroke weight corresponding to the reference pen state value.
In some embodiments, for example, in this embodiment, the step S160 may include the following steps: judging whether the reference interval contains the initial pen-down point; if the reference interval contains the initial stroke point, drawing a subsequent stroke by using the stroke weight corresponding to the reference stroke state value; and if the reference interval does not contain the initial stroke point, redrawing the finished stroke and continuing to draw the subsequent strokes according to the stroke weight corresponding to the reference stroke state value.
In the embodiment of the invention, if the reference interval contains the initial stroke-falling point, the selected stroke-falling point is indicated to start from the initial stroke-falling point, the previously drawn stroke is not required to be modified, and the subsequent stroke is directly completed.
