FIG. 5 is a schematic view of a user operation interface in the handwriting generating method according to the embodiment of the present application. Fig. 6 is a schematic diagram illustrating an effect of the handwriting generating method according to the embodiment of the present application. The handwriting generating method is applied to terminal equipment, and can comprise the following steps:
In this embodiment, the display terminal specifically refers to a display device with a touch input function, and a touch screen is taken as an example here. The trigger condition of the touch operation may be that the user directly presses on the touch screen with a finger to trigger or presses on the touch screen with a touch pen to trigger. When a touch operation initiated by a user is detected, determining a sampling point of the initial of the handwriting to be generated according to the initiation position of the touch operation on the touch screen, as shown in fig. 2.
And 102, when the mobile operation acting on the display terminal is detected, sequentially collecting key sampling points on a mobile track corresponding to the mobile operation.
In the present embodiment, the trigger condition of the moving operation may be that the user directly touches the touch screen with a finger and moves in a specified direction, or that the user touches the touch screen with a utility stylus and moves in a specified direction. And after the initial sampling point of the handwriting is determined, sequentially collecting key sampling points on a moving track corresponding to the moving operation according to the detected moving operation.
For example, when a movement operation of a user on the touch screen is detected, sampling is performed on a movement track generated by the touch screen at a sampling frequency of 30ms each time, so that a plurality of key sampling points on the movement track input by the user on the current touch screen are obtained.
It should be noted that the preset frequency for sampling the moving track may be set based on the performance of different touch screens themselves, and therefore, it should be clear that the preset frequency for sampling the moving track is not limited by the present invention.
And 103, respectively constructing corresponding preset pen-touch patterns based on the initial sampling points and the key sampling points.
In order to construct the writing trace, in this embodiment, a preset stroke pattern is constructed based on the initial sampling point and the key sampling point to construct a model structure of the writing trace, and meanwhile, preparation is made for subsequently determining a common tangent line.
In some embodiments, the process of constructing the predetermined compiled pattern includes: constructing a preset pen-touch pattern by taking the initial sampling point or the key sampling point as a circle center and combining preset attribute information; wherein the preset pen touch pattern comprises an ellipse or a circle; the preset attribute information includes major and minor axes of an ellipse, or a radius of a circle.
It should be noted that the preset attribute information is preset and can be directly called, and once the attribute information is set, the attribute information is not changed in the writing process. The preset attribute information may be set based on the performance of the different touch screens themselves, and therefore, it should be clear that the present invention does not limit the preset attribute information.
In the actual running process of the program, the preset Brush pattern takes an ellipse as an example, when a user presses a finger or uses a touch pen on a touch screen, a Broad Brush class is created, the property and the width of the Brush are set, and the sizes of the long axis and the short axis of the Brush are initialized. And calling start Stroke () to calculate and draw the Path of the head track of the brush and record the initial collection point.
In some embodiments, the constructing the preset stroke pattern by using the initial sampling point or the key sampling point as a center of a circle and combining preset attribute information includes:
constructing an initial stroke pattern by taking the initial sampling point or the key sampling point as a circle center and combining preset attribute information
And rotating the initial pen-touch pattern by a preset angle relative to the initial sampling point or the key sampling point to obtain the preset pen-touch pattern.
In this embodiment, before obtaining the preset pen-touch pattern, the initial pen-touch pattern is rotated by a preset angle relative to the initial sampling point or the key sampling point to obtain the preset pen-touch pattern. For example, the initial stroke pattern is rotated by-25 °, so that the finally presented handwriting has a certain inclination angle, which is closer to the actual handwriting effect.
It should be noted that the preset angle can be set based on the performance of different touch screens themselves, and therefore, it should be clear that the preset angle is not limited by the present invention.
And 104, determining common tangent lines between the adjacent preset pen touch patterns, and constructing a closed area according to all the common tangent lines.
In this embodiment, as shown in fig. 3, between two adjacent sampling points, a line segment parallel to and tangent to two adjacent predetermined touch patterns is taken as a common tangent of the two adjacent predetermined touch patterns. After the common tangent line is obtained, tangent points on the common tangent lines on two sides of the preset pen touch pattern on the moving track are respectively determined, all the tangent points on the same side are successively connected according to the acquisition time to obtain two parallel area boundary lines, and the two parallel area boundary lines are connected in an ending mode to obtain a closed area.
In some embodiments, in order to simulate the handwriting effect more truly, a bezier curve is selected for connection in the process of connecting the tangent points. Bezier curves (also known as bezier curves or bezier curves) are mathematical curves applied to two-dimensional graphics applications, by which curves can be drawn accurately.
In some embodiments, prior to constructing the enclosed area according to all common tangents, the method further comprises:
judging whether the overlapping area between two adjacent preset pen touch patterns is larger than or equal to a preset threshold value or not;
and if the overlapping area between two adjacent preset pen touch patterns is larger than or equal to a preset threshold value, one tangent point on the same common tangent line is reserved for constructing the boundary line of the region.
In order to avoid that sampling points acquired on a moving track are too dense, even if sampling frequency is preset, erroneous acquisition is difficult to avoid, so that the situation that excessive overlapping occurs between preset pen touch patterns constructed and obtained according to the sampling points is caused, further, the trend of a common tangent line is frequently changed, and finally, the problem that the edge of a displayed handwriting has a sawtooth shape or a wavy shape is solved, namely, the connection part is not smooth enough, and the aesthetic feeling is influenced. Therefore, in this embodiment, by determining whether the overlapping area between two adjacent preset pen contact patterns is greater than or equal to the preset threshold, if the overlapping area between two adjacent preset pen contact patterns is greater than or equal to the preset threshold, one of the tangent points (i.e., the control points shown in fig. 3) located on the same common tangent line is retained for region boundary line construction, so as to solve the problem caused by excessive density of sampling points.
And 105, filling the pattern into the closed area to obtain the handwriting.
In this embodiment, after the closed area is obtained, pattern filling is performed on the closed area to obtain the handwriting. For example, the closed area is filled with preset colors, and handwriting close to the real writing effect is obtained.
In some embodiments, after the pattern filling of the closed area and before the writing is obtained, the method further comprises:
when a termination operation acting on the display terminal is detected, determining a sampling point of the termination of the handwriting to be generated according to an initiation position of the termination operation on the display terminal;
and constructing a preset pen-touch pattern at the terminated sampling point, and filling the preset pen-touch pattern.
In the embodiment, as shown in fig. 4, the trigger condition for terminating the operation may be that the user's finger or the touch pen is lifted off the surface of the touch screen to trigger. When the termination operation acting on the touch screen is detected, determining a sampling point of the termination of the handwriting to be generated according to the initiation position of the termination operation on the touch screen, constructing a preset pen-touch pattern at the sampling point of the termination, and filling the preset pen-touch pattern to simulate the termination of the real handwriting.
All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, in the handwriting generating method provided in the embodiment of the present application, when a touch operation acting on a display terminal is detected, according to an initiation position of the touch operation on the display terminal, a sampling point of an initiation of a to-be-generated handwriting is determined; when the mobile operation acting on the display terminal is detected, sequentially collecting key sampling points on a mobile track corresponding to the mobile operation; respectively constructing corresponding preset pen touch patterns based on the initial sampling points and the key sampling points; determining common tangent lines between the adjacent preset pen touch patterns, and constructing a closed area according to all the common tangent lines; and filling the pattern in the closed area to obtain the writing handwriting.
