The following describes a method for adjusting a pattern according to an embodiment of the present invention with reference to a specific embodiment.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for adjusting a pattern according to an embodiment of the present invention, where the method includes the following steps 101-105.
Specifically, the star to be adjusted may be a positive star or a non-positive star, and the application does not limit this.
In an implementation manner of the present invention, the vertex angle number may be obtained by obtaining a vertex angle number of a star to be adjusted, which is input by a user. For example, the electronic device may generate a dialog box on the display interface, and the user inputs the number of vertices of the star to be adjusted in the dialog box, so that the electronic device obtains the number of vertices input by the user.
In another implementation manner of the invention, the vertex of the star to be adjusted can be identified, and the vertex angle number of the star to be adjusted is obtained according to the vertex number of the star to be adjusted.
And 102, acquiring the width of the star to be adjusted as the representation information under the condition that the number of the vertex angles is even.
Specifically, in an implementation manner of the present invention, the width may be obtained by obtaining a width of the star to be adjusted, which is input by a user. For example, the electronic device may generate a dialog box in the display interface in which the user enters the width of the star to be tuned, so that the electronic device obtains the width entered by the user.
In another implementation manner of the present invention, the vertex of the star to be adjusted may be identified, the coordinates of the identified vertex may be obtained, and the width of the star to be adjusted may be calculated according to the identified vertex coordinates.
In another implementation manner of the present invention, the width of the circumscribed rectangle of the star to be adjusted can be obtained, and the obtained width is used as the width of the star to be adjusted. Specifically, referring to fig. 2, the width of the five-pointed star to be adjusted can be obtained by identifying the width of the circumscribed rectangle.
And 103, acquiring the height of the star to be adjusted as the representation information under the condition that the number of the vertex angles is odd.
Specifically, the implementation manner of this step is similar to that of step 102, and the height of the star to be adjusted may be obtained by means of user input, vertex recognition, circumscribed rectangle recognition, or the like, which is not described in detail herein.
And step 104, calculating the distance from the center point to the vertex of the positive star determined by the vertex angle number and the representation information according to the vertex angle number and the representation information.
In one embodiment of the present invention, the distance r may be calculated by the following expression:
wherein m represents the above characterizing information, n represents the number of vertex angles, and a, b, and c represent preset parameters.
Specifically, the value of a may be 2, the value of b may be 3, and the value of c may be 2. Under the condition, if the number of the vertex angles of the star to be adjusted is 6 and the characterization information is 20 pixel points, the distance from the center point to the vertex of the regular hexagon star with the width of 20 pixel points can be calculated according to the formula:
the distance from the center point to the vertex of the regular hexagon star with the width of 20 pixel points is 12 pixel points obtained by calculation.
In addition to the above, the values of a, b, and c may be other values, for example, a may be 1, 1.5, 2.5, 3, etc., b may be 2.5, 3.5, 4, etc., and c may be 1, 1.5, 2.5, 3, etc. The embodiments of the present invention are described above as examples, and the schemes provided by the embodiments of the present invention are not limited.
And 105, adjusting the star to be adjusted according to the vertex angle number, the representation information and the distance to obtain an adjusted star with the same vertex angle and the same side length.
The inventor finds that the star has different characteristics when the star has different vertex angles in the experimental process. In view of this, in one embodiment of the present invention, if the number of the star points to be adjusted is even, the first value is calculated according to the following expression, and the height of the star to be adjusted is adjusted to the first value while keeping the number of the star points to be adjusted and the width unchanged:
wherein mod represents a remainder operator, n represents a vertex angle number, r represents the distance, m represents characterization information, and d represents a preset parameter.
Specifically, the value of d may be 4. Under the condition, if the number of the vertex angles of the star to be adjusted is 6 and the width is 20 pixel points, the height of the hexagonal star with the width of 20 pixel points can be calculated according to the formula:
the height of the hexagonal star with the width of 20 pixel points is 24 pixel points through calculation.
In addition to the above, the value of d may be other values, for example, the value of d may be 3, 5, 6, and so on. The embodiments of the present invention are described above as examples, and the schemes provided by the embodiments of the present invention are not limited.
In another embodiment of the present invention, when the number of the star points to be adjusted is odd, a second value is calculated according to the following expression, and the width of the star to be adjusted is adjusted to the second value while the number of the star points to be adjusted and the height of the star to be adjusted are kept unchanged:
wherein mod represents a remainder operator, n represents the number of the vertex angles, r represents a distance, and e and f represent preset parameters.
Specifically, the value of e may be 5, and the value of f may be 4. In this case, if the number of the vertex angles of the star to be adjusted is 5 and the height is 20 pixel points, the width of the regular five-pointed star with the height of 20 pixel points can be calculated according to the formula as follows:
the calculation results show that the width of the regular five-pointed star with the height of 20 pixel points is 21 pixel points.
In addition to the above, the values of e and f may be other values, for example, the value of e may be 3, 4, 6, etc., and the value of f may be 2, 3, 5, etc. The embodiments of the present invention are described above as examples, and the schemes provided by the embodiments of the present invention are not limited.
It can be seen that, when the graph is adjusted by applying the schemes provided by the embodiments of the present invention, since the first numerical value and the second numerical value obtained by calculation are results obtained by calculation according to the positive star, the star to be adjusted is adjusted according to the calculation results, and an adjusted star having the same vertex angle and the same side length is obtained, and the adjusted star can be considered as the positive star. Compared with the prior art, when the scheme provided by the embodiment of the invention is applied to star adjustment, the judgment by naked eyes is not needed, and the graph adjustment is carried out according to the height, the width and the vertex angle of the star, so that the influence of subjective factors of a user on an adjustment result can be reduced, and the accuracy of adjusting the star to be a positive star is improved.
