Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Fig. 1 is a schematic flow chart of an image contour point adjusting method according to an embodiment of the present invention, as shown in fig. 1, the image contour point adjusting method includes the following steps:
S101, acquiring an original contour point and adjustment information corresponding to the original contour point;
That is to say, after the image to be processed is acquired, corresponding original contour points are extracted according to the image to be processed, and adjustment information of the user for the original contour points is acquired.
The method for extracting the original contour point corresponding to the image to be processed has been described in detail in the prior art, and is not described herein again.
The information contained in the adjustment information can be various; for example, including adjustment direction and adjustment distance; furthermore, the adjustment information may be acquired in various manners.
As an example, the adjustment information is determined by a value input by a user, and if the value input by the user is +50, the adjustment information is represented as outward expansion by 50 pixels (that is, the adjustment direction is a direction away from the image to be processed, and the distance is 50 pixels); and if the value input by the user is-50, it indicates that the adjustment information is to zoom in by 50 pixels (i.e., the adjustment direction is toward the image to be processed, and the distance is 50 pixels).
As another example, the adjustment direction is obtained according to operation information of the mouse by the user, after the user continuously clicks the mouse, the adjustment direction is obtained according to the moving direction of the mouse, and the adjustment distance is determined according to the distance between the position where the user finally releases the mouse and the position where the mouse is initially clicked.
As another example, first, an adjusting module corresponding to the adjusting information is set, where the adjusting module includes an adjusting slide bar and an adjusting block, initially, the adjusting block is at a critical point on the adjusting slide bar, when the user controls the adjusting block to move leftward, the adjusting direction is indicated as inward contraction, and an adjusting distance is determined according to a distance between the adjusting block and the critical point; when the user controls the adjusting block to move rightwards, the adjusting direction is outward expansion, and the adjusting distance is determined according to the distance between the adjusting block and the critical point.
S102, calculating corresponding original adjustment contour points according to the original contour points and the adjustment information;
That is, the original contour points and the adjustment information are calculated to obtain the original adjustment contour points corresponding to the original contour points.
There are various ways to calculate the corresponding original adjustment contour points according to the original contour points and the adjustment information.
As an example, calculating corresponding original adjusted contour points from the original contour points and the adjustment information includes: and calculating a normal corresponding to the original contour point according to the adjustment direction, and determining the original adjustment contour point corresponding to the original contour point according to the direction of the normal and the adjustment distance.

It should be noted that, the above-mentioned judging process is performed in sequence, that is, the judgment of the original contour point and the original adjustment contour point is performed in sequence according to the sequence of each point in the point list; for example, in the judgments of fig. 2 and 3, the profile runs counter-clockwise; and vice versa clockwise.
And S105, looping the step S103 and the step S104 until all the original contour points and the original adjustment contour points are judged, and determining final adjustment contour points according to the judgment result.
That is, the steps S103 and S104 are executed in a loop until all the original contour points and the original adjusted contour points are determined, so as to determine the final adjusted contour points according to the determination result.
As an example, when 6 original adjustment contour points (0,1,2,3,4,5,) are included in the point list; firstly, according to the sorting of points in the point list, judging whether the point 0 and the point 1 meet the conditions according to the step S103 and the step S104, if so, reserving the point 0 and the point 1, then judging whether the point 1 and the point 2 meet the conditions according to the step S103 and the step S104, and if so, reserving the point 1 and the point 2; then, judging whether the point 2 and the point 3 meet the conditions according to the step S103 and the step S104, and if not, deleting the point 2 and the point 3; next, it is determined whether or not the point 1 and the point 4 meet the conditions according to the step S103 and the step S104; and circulating until 6 points in the point list are judged.
