Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A text transformation special effect processing method provided by an embodiment of the present invention, as shown in FIG. 2, mainly includes the following steps:

Step S110: Set a text deformation designer consisting of an initial rule rectangle and a plurality of control points, and the control point is used to control the rectangle of the text deformation designer to perform linear deformation or quadratic deformation.

Among them, setting the text deformation designer provides two working modes, one for designing linear deformation effects and the other for designing secondary deformation effects. In this embodiment, the text deformation designer is mainly composed of an initial regular rectangle and four control points, and the user designs the desired target shape by dragging four control points. The design of the text deformation designer is shown in Figures 3 and 4. When the rectangle that controls the text morphing designer is linearly deformed, the control point specifying the initial rectangle is four corner vertices, as shown in FIG. 3, LT, RT, RB, LB. When the rectangle of the text deformation designer is controlled to perform quadratic deformation, the control point of the designated initial rectangle is the midpoint on the four sides of the rectangle, as shown in FIG. 4, MT, RM, MB, LM. FIG. 3 is a schematic structural view of a text deformation designer for designing a linear deformation effect, by which a user can design a linear deformation effect; wherein, the linear deformation effect refers to a text deformation effect, and all the tensile deformations are straight lines. Type. The text deformation setter in FIG. 3 is composed of an initial regular rectangle 10 and four corner vertices LT, RT, RB, LB of the corresponding rectangle, and four corner vertices LT, RT, RB, LB are the text deformation designer of FIG. The four control points specify the initial coordinates of the four control points of the initial rectangle as LT(-1, 1), RT(1, 1), RB(1, -1), LB(-1,

-1).

Figure 4 shows the structure of the text deformation designer used to design the quadratic deformation effect. Through this designer, the user can design the quadratic deformation effect. Among them, the quadratic deformation effect refers to: The extension deformation is parabolic. In the embodiment shown in Fig. 4, four control points are set on the four sides of the rectangle, which are: MT, RM, MB, LM. The initial coordinates of the four control points specifying the initial rectangle are MT ( 0, 1 ), RM ( 1 , 0 ), MB (-1 , 0), LM (0, -1).

Step S120: Receive a text that needs to be deformed input by the user, convert the text that needs to be transformed into a vector graphic, and input it to the text deformation designer.

Vectors use lines and curves to describe graphics. The elements of these graphics are points, lines, rectangles, polygons, circles, and arcs, and so on. In the embodiment of the present invention, the text data to be deformed is input into the text deformation designer so that the text is deformed following the change of the text deformation designer.

Step S130: Receive an operation instruction that the user drags the control point of the text deformation designer, and linearly deforms the text vector graphic and/or the second-order deformation according to the mathematical model dynamically created by the text deformation designer.

In the embodiment of the present invention, the user's operation instruction is converted into a text deformation parameter, and the text is changed. The shape parameter includes an initial control point parameter and a vector motion parameter, wherein, in linear deformation, the four angular vertices LT, RT, RB, and LB as described above are the four control points of the text deformation designer of the FIG. The initial coordinates of the four control points of the specified initial rectangle are LT(-1, 1), RT(1, 1), RB(1, -1), LB(-1, -1), which are expressed as the initial of linear deformation. Control point parameters. In the quadratic deformation, the initial control point parameter is the initial coordinates MT( 0, 1 ) and RM( 1 , which specify the four control points of the initial rectangle.

0), MB (-1, 0), LM (0,

Type and user The target shape determined after stretching, abstracting the coordinates of each control point after transformation, outputting a parameter E indicating the deformation type and a matrix of 2 rows and 2 columns (ie vector motion parameters) are recorded as:

( Point 1 Point

M= (Formula 1).

Point 3 Point

The parameter E represents the type of text deformation, and the value is 1 or 2, 1 represents linear deformation, and 2 represents quadratic deformation. The four elements of the matrix M, Pointl, Point2, Point3, and Point4, respectively correspond to the positions of the four control points, and the linear deformations correspond to the relative coordinates of the four points LT, RT, LB, and RB in Figure 3, respectively. The deformations correspond to the relative coordinates of the four points of MT, RM, MB, and LM in FIG. 4, respectively.

The shape generates a thumbnail of the text deformation effect, which is convenient for the user to customize the text deformation effect template.

In addition, according to the mathematical knowledge, it is known that determining a straight line requires a minimum of two points, and determining a quadratic parabola requires a minimum of 3 points.

According to the parameter E output by the text deformation designer, the type of text deformation effect designed by the user can be known, that is, whether the target deformation shape is linear or quadratic parabola. a) The first deformation parabola is a straight line, that is, the text deformation designer is the line For the sexual deformation, the four corner vertices of the text deformation designer rectangle are the four control points. It is known that two points can determine a straight line, so the function of the parabolic model of the text deformation can be determined according to the data of the four vertices, and then the final text deformation effect can be generated by correspondingly processing the position of the text according to the function. The details are as follows.

As shown in FIG. 5, when the rectangle controlling the text deformation designer is linearly deformed, the control point is the coordinates of the four corner vertices, and the positions of the four control points before the change are set to a, b, c, d; After the text deformation designer, the four control points are located at a, b, c, d,. When the position of the two corners of the vertex b, c of the border is dragged to the position b ¹ , c ¹ , it can be seen that the shape of the border has changed. The text transformation effects corresponding to the above model are shown in Fig. 6a and Fig. 6b, Fig. 6a is the text before the change, and Fig. 6b is the text after the deformation effect is applied.

According to the deformation processing of the text deformation designer according to the embodiment of the present invention, the coordinates of the four corners of the character deformation designer rectangle before the change in FIG. 5 are respectively a(-l, 1), b(l, 1), c(l, -l), d(-l, -1), B In the linear text modification of Fig. 5, point B rises by 0.2 units to b', and point c rises by 1.1 units to c, then after deformation The matrix can be expressed as:

( (-1,1) (1,1.2)

(-1,-1) (1, 0.3

Output the coordinate data of the changed four control points, where Pointl , Point2, Point3 ,

Point4 represents the coordinates of a, b', c, d' after deformation. According to the known two points to determine a straight line, let the line equation y = kx + h, then Pointl (ie the coordinate of a (x, y) = (-1, 1)), Point2 (the coordinates of b' ( _x , y ) = (l , 1.2)) Two points are substituted into the linear equation y = kx + h, as follows:

l = k * (-l) + h

l .2 = k * l + h

Solved: k = 0.5, h = 0.7. Then we can determine a, b after deformation, the equation of this line is y = 0.5x + 0.7.

Similarly, the coordinates of the two ends of the straight line b, c, the straight line c, d, and the straight line d, a are sequentially substituted into the linear equation: y = kx + h (where x, y are coordinate value data), The linear equation function of the straight line a, b, the linear equation function of the straight line b'c', the linear equation function of the straight line c'd', and the linear equation function of the straight line d, a are obtained in sequence. This creates a linear mapping from the area abed to the areas a, b, c, d.

b) The case where the second parabola is a 2 parabola.

When the text deformation designer performs the quadratic deformation, as shown in FIG. 7, the midpoint on the four sides of the initial regular rectangle of the text deformation designer is the four control points; and the four control points before the change are set. The position is 6, f, g, h; the changed text deformation designer has four control point positions e, f, g, h.

The quadratic parabola in the present invention uses a parabola. It is known that three points can determine a parabola. Therefore, according to the coordinates of the four control points output by the text deformation effect designer, four vertices are added (in the quadratic deformation, four The data of a fixed point coordinate can determine the function of the text transformation parabola, and then the corresponding text transformation effect can be generated according to the function of the function.

As shown in Figure 7, the four corners of the border rectangle of the default text are set as a , b , c , d respectively. The positions of the four control points before the change are e, f, g, h; the positions of the four control points of the changed text deformation designer are e, f, g, h,; When the midpoints 6, f, g, and h are dragged to e, f, g, and h, the text transformation effects corresponding to the model are shown in Fig. 8a and Fig. 8b, and Fig. 8a is the text before the change. Figure 8b is the text after applying the text effect.

According to the deformation processing of the text deformation designer according to the embodiment of the present invention, four corners can be obtained. The coordinates are a(-l, 1), b(l, 1), c(l, -l), d(-l, -l). The coordinates of the e, f, g, and h points of the four control points before the change in Fig. 7 are respectively set to e (0, 1), f (l, 0), g (-l, 0), h (0, -1): In the linear text transformation example of Fig. 8, two points e and g are compressed inward by 0.3 units; f and h are expanded outward by 0.2 units, and the deformed matrix can be expressed as:

( Point 1 Point 2 ( (0,0.7) (1.2,0)

M=

Point 3 Point (0,-0.7) (-1.2,0) In this embodiment, Pointl, Point2, Point3, and Point4 represent the coordinates of e, f, g, and h after deformation, respectively. Let the linear equation y = Kx + h, Let the curve equation be: y = ίχ ² + jx + q (Equation 3).

As shown in Fig. 8, the coordinate values a(-l, l), e, (0, 0.7), b(l, 1) of the three points a, e, and b are substituted into the curve equation (formula 3). As follows: l = ix(-iy + jx(-l + q; 0.7 = x0 ² + jxO + ^: 1 = XI ² + jl + q;

Solving: i=0.3, j=0, q=0.7, then the curve equation of the parabola a, e, and b after deformation is determined as: y = 0.3; c ² +0x; c + 0.7.

Similarly, the coordinate values of the two endpoints and one midpoint of each parabola in the parabola bf, c, parabola c g'd and parabola d h'a are substituted into the curve equation (Equation 3) to solve i, j, q, respectively. You can calculate the equations for several other parabolas. This creates a mapping model from the region efgh to the region e, f, g, h, transformed region.

Step S140: The text deformation designer outputs the transformed special effect text graphic.

It can be seen from the above that in the embodiment of the present invention, the models of linear deformation or quadratic deformation have been established, and then the GDI provided by the Windows system is used. (GraphicsDevicelnterface graphics device interface) + graphics library, save text

GraphicsPa th (a class in the Windows graphics library that records all the processes that the user draws, can provide the ability to draw all the content at once), where Graph icsPath is a class in the Windows graphics library that is used to record users. All the processes you draw can provide the ability to draw all the content at once. Then, the PathDa ta data can be obtained, and the data structure is a collection of control points of the recorded text, where PathData is a helper class in the Windows graphics library, used to record the data in the Graphicspath. Then, according to the established linear mapping relationship, after calculation, the position of a certain point in the transformation can be obtained. After all the points are completed, the target text deformation effect is obtained.

In step S140, the method further comprises: dividing the generated special effect character graphic, and generating independent sub-word blocks according to the number of input characters, and in the specific implementation, vertically projecting on the image line according to a blank gap between the words and the words The formed blank interval, and the interval between the Chinese characters are larger than the interval between the Chinese characters, and the generated special effect character graphics are divided into Chinese characters, and the independent sub-word blocks are generated according to the number of input characters.

Among them, word segmentation is to separate a single character image from the segmented text image lines. The correctness of the word segmentation directly affects the recognition result. The following is an example of a single Chinese character segmentation:

For example, the main method of word segmentation can be determined by means of the idea of segmentation of Chinese character image lines: a single character image is segmented by a blank space formed by the vertical gap between the word and the word on the vertical projection of the image line.

In fact, by analyzing the vertical projection of the image line, it can be found that the blank space portion on the vertical projection is not only not widened by the blank space between the lines, but also unevenly distributed. Because of In Chinese texts, the spacing of Chinese characters is far less obvious than that of line spacing. At the same time, there are a considerable number of Chinese characters in Chinese characters that are left and right structures or left, center, and right structures. The vertical projection of these Chinese characters will also have blank gaps inside a single word. , making word segmentation of text Chinese characters more difficult than row segmentation.

In order to solve this problem, it is possible to use the feature that the interval between Chinese characters is generally larger than the interval between Chinese characters to first perform coarse segmentation of Chinese characters, and then to perform fine segmentation based on the fact that Chinese characters are basically square graphics.

The specific implementation is as follows: According to the line segmentation of Chinese characters, the height information of the Chinese characters can be obtained, so that the basic width of the Chinese characters can be estimated; for each of the roughly divided Chinese characters, the width information is measured, and the starting position of the coarse segmentation is Starting point, search in the left and right directions, and make a slight adjustment to the starting position, so that the word segmentation is more accurate. This method not only ensures that the internal structure of a single Chinese character is not separated, but also avoids the edge of the Chinese character. The segmentation result basically extracts the complete Chinese character and eliminates the false cut of the stroke. In this way, the generated special effect text graphic is divided into a plurality of independent sub-word blocks, and the transformed special effect text graphic is output through the text deformation designer.

It can be seen from the above that the embodiment of the present invention reduces the labor cost for completing a text special effect, and at the same time reduces the research and development cost, and can realize different text shape special effects by adjusting the matrix parameters of the single tube, and no longer need Develop for specific effects. And the device adds a new function that can arbitrarily deform the text, and realizes segmentation of each glyph for the generated block, each glyph shape is coherent, and can be freely moved and edited, so that the user can easily make a favorite The text deformation effects provide convenience for the user and enhance the user experience.
