With the popularization of mobile terminal devices, a large number of small programs or applications are emerging in the application market of the mobile terminal devices, wherein applications capable of realizing a graphic editing function are more and more popular with users, generally, the applications capable of realizing the graphic editing function can provide customized templates, primitive lists and other materials for users, meanwhile, the functions of zooming, rotating, editing characters and the like of primitives are supported, and the users can make personal electronic business cards and posters for picture refinement and the like after simple learning.
At present, when a user needs to perform small-amplitude position alignment adjustment on a certain primitive, one generally adopted method is to enlarge an area where the primitive is located, so as to assist the user in adjusting the position of the primitive, and in this case, the condition that the primitive display is fuzzy sometimes caused by the limitation of the size of a display screen of a mobile terminal or the setting of pixels, so that the user is not convenient to identify and operate the primitive; in another mode, the primitive is dragged by means of a reference line or a grid line, so that the position of the primitive is adjusted, under the condition, a user sometimes difficultly grasps the degree of the primitive adjustment, the position of the primitive is greatly deviated due to the fact that the speed of dragging the primitive is too high, or the speed of dragging the primitive is too low, the position of the primitive is not obviously changed, the user needs to repeatedly try and continuously adjust the position of the primitive, the whole process is time-consuming and labor-consuming, and the user experience is poor.
In order to solve the above problem, the present application provides a primitive alignment method, where an execution subject of the method includes but is not limited to at least one of a server, a terminal, and other electronic devices that can be configured to execute the method provided by the embodiments of the present application.

Referring to fig. 1, an embodiment of the present application provides a flowchart of a primitive alignment method, as shown in fig. 1, the primitive alignment method includes:
in the embodiment of the present application, the primitive is a short form of a graphic element, the page may be any graphic editing page, and the page may include a plurality of graphic elements such as a button element, a prompt box, an editing box, and a picture.
The primitive to be adjusted refers to a graphic element which moves in a page, and the reference primitive refers to a graphic element which does not move and has a fixed position in the page.
In the implementation, the operations of mouse clicking, mouse dragging and the like of a user are monitored to monitor whether the primitive to be adjusted is displaced, and if the primitive to be adjusted is monitored to be displaced, the distances between the primitive to be adjusted and all reference primitives positioned on the same page are calculated.
102, when monitoring at least one reference primitive of which the distance from the primitive to be adjusted is smaller than a first threshold value, respectively predicting an alignment mode of the at least one reference primitive and generating an adsorption line corresponding to the alignment mode;
in the embodiment of the present application, the value of the first threshold is not limited, and may be set according to actual requirements, for example, the first threshold is set to be 5 centimeters, 8 centimeters, and the like.
In the process of aligning the primitives, when the distance between the primitive to be adjusted and at least one reference primitive is monitored to be gradually reduced to a first threshold value, the at least one reference primitive is judged to be possibly the primitive to be aligned with the primitive to be adjusted, and adsorption lines corresponding to the at least one reference primitive are respectively generated.
When an adsorption line corresponding to the primitive to be adjusted and the reference primitive is generated for each reference primitive in the at least one reference primitive, firstly predicting an alignment mode of the primitive to be adjusted and the reference primitive according to a position relation of the reference primitive and the primitive to be adjusted, and then generating the adsorption line corresponding to the alignment mode according to the predicted alignment mode.
The absorption line may be a straight line, a radial line, a line segment, or other various forms, the direction of the absorption line is not limited in the embodiment of the present application, and the absorption line may be a horizontal line in a horizontal direction, a vertical line in a vertical direction, or an oblique line inclined in a certain direction.
As shown in fig. 2, the above alignment means includes, but is not limited to, left alignment, right alignment, up alignment, down alignment, and transverse center alignment, i.e., longitudinal center alignment.
103, when a target reference primitive with a distance smaller than a second threshold value from the primitive to be adjusted is monitored, positioning an alignment position in the primitive to be adjusted according to an alignment mode corresponding to an adsorption line of the target reference primitive;
in this embodiment of the application, specific values of the second threshold are not limited, but it should be noted that the values of the second threshold need to be smaller than the values of the first threshold.
In detail, when it is monitored that the distance between the primitive to be adjusted and the target reference primitive is further reduced to a second threshold, the alignment position in the primitive to be adjusted is positioned according to the adsorption line corresponding to the generated target reference primitive and the alignment mode corresponding to the adsorption line, wherein the alignment position in the primitive to be adjusted is the edge point of the primitive to be adjusted corresponding to the alignment mode.
Specifically, as shown in fig. 3, the primitive to be adjusted is left-aligned with the target reference primitive, and the adsorption line is generated on the left edge line of the target reference primitive, for example, at this time, the alignment position of the primitive to be adjusted is selected as the left edge point a of the primitive to be adjusted.
It should be noted that, because the value of the second threshold is smaller than the value of the first threshold, when the distance between the primitive to be adjusted and the target reference primitive is reduced to the second threshold, an adsorption line corresponding to the target reference primitive is necessarily generated in advance.
in the implementation, since the alignment position of the primitive to be adjusted is determined according to the alignment mode corresponding to the adsorption line of the target reference primitive, the alignment position of the primitive to be adjusted is overlapped with the adsorption line of the target primitive, so that the alignment of the primitive to be adjusted and the target reference primitive can be realized.
According to the method, the distance between the primitive to be adjusted and the reference primitive is calculated in real time, when the distance is reduced to the first threshold value, the adsorption line corresponding to the alignment mode of the reference primitive is generated, when the distance is further reduced to the second threshold value, the alignment position of the primitive to be adjusted is determined according to the alignment mode, the position of the primitive to be adjusted is adjusted according to the alignment position and the adsorption line, the effect of automatic alignment of the primitive to be adjusted and the reference primitive is achieved, a user does not need to manually adjust or move the primitive to be adjusted repeatedly, and therefore the primitive alignment operation efficiency and the user operation experience are improved.
As an optional implementation manner, in order to prevent an incorrect operation caused by the problem of hand sliding, the adjusting method further includes, after adjusting the position of the primitive to be adjusted until the alignment position in the primitive to be adjusted overlaps with the adsorption line of the target reference primitive:
monitoring an instruction for moving a primitive to be adjusted, and determining the moving speed and/or the displacement of the primitive to be adjusted;
when the moving speed is judged to be larger than a preset speed threshold value, the position of the primitive to be adjusted is adjusted according to the moving speed, and/or when the displacement is judged to be larger than a preset displacement threshold value, the position of the primitive to be adjusted is adjusted according to the displacement;
otherwise, judging the instruction for moving the primitive to be adjusted as an invalid instruction.
In implementation, after a primitive to be adjusted is aligned with a target reference primitive, when the movement of the primitive to be adjusted of a user is monitored, firstly, the movement speed and/or the displacement of the primitive to be adjusted is obtained, whether the operation of the user is a misoperation is judged according to the movement speed and/or the displacement, if the movement speed is greater than a preset speed threshold and/or the displacement is greater than a preset displacement threshold, the operation of the user is judged to be an effective operation, and the position of the primitive to be adjusted is adjusted according to the movement speed and/or the displacement of the corresponding primitive to be adjusted; otherwise, judging that the operation of the user is invalid operation, and not adjusting the position of the primitive to be adjusted.
In the embodiment of the application, the values of the preset speed threshold and the preset displacement threshold are not limited, and can be adjusted according to actual requirements.
It should be noted that the moving the primitive to be adjusted may only include moving the primitive to be adjusted aligned with the target reference primitive to a position not aligned with the target reference primitive, or may also include moving the primitive to be adjusted while maintaining alignment with the target reference primitive, for example, moving the primitive to be adjusted up and down while maintaining left alignment with the target reference primitive.
According to the method, compared with the method that the user moves the aligned primitive to be adjusted and the misaligned primitive to be adjusted, the user needs higher moving speed and/or larger displacement, the phenomenon of hand slip can be effectively prevented, and larger position deviation is avoided when the primitive to be adjusted is moved.
Referring to fig. 4, the following describes in detail a method for calculating distances between the primitive to be adjusted and the reference primitives located on the same page in step 101, and calculates the distances between the primitive to be adjusted and the reference primitives located on the same page, including the following steps:
in the implementation, a coordinate system is established first, and the distance between the primitive to be adjusted and the reference primitive is calculated based on the coordinate system.
in the implementation, when selecting the primitive to be adjusted and the reference point on each reference primitive, an optional implementation manner is to determine the primitive to be adjusted and the reference point on each reference primitive according to a predefined reference point position, for example, predefined to use the center point of the primitive as the reference point of the primitive; another optional implementation manner is to obtain the edge contour of the primitive to be adjusted and each reference primitive by using an edge detection algorithm, and determine the corresponding reference point according to the edge contour, for example, using any vertex in the edge contour map as the reference point of the corresponding primitive.
As an optional implementation manner, selecting a reference point on the primitive to be adjusted and the reference primitive respectively includes:
respectively determining the edge outlines of the primitive to be adjusted and the reference primitive by utilizing an edge detection algorithm;
selecting a first point in the edge contour point set of the primitive to be adjusted, and selecting a second point in the edge contour point set of the reference primitive, so that the distance between the first point and the second point is the closest;
and determining the first point as a reference point of the primitive to be adjusted, and determining the second point as a reference point of the reference primitive.
It should be noted that the reference points selected on the primitive to be adjusted are selected according to the corresponding reference primitives, and the reference points selected on the primitive to be adjusted may be the same or different for different reference primitives.
It should be noted that, if there are multiple groups of first points and second points in the edge contour point set of the primitive to be adjusted and the edge contour point set of the reference primitive, so that the distance between the first point and the second point is the closest, any one of the groups of first points and second points is selected, the first point is determined as the reference point of the primitive to be adjusted, and the second point is determined as the reference point of the reference primitive.
As shown in fig. 5, in the edge contour point set of the primitive to be adjusted, the first point of the reference primitive 1 is a point B in the graph, and the first point of the reference primitive 1 is a point C in the graph, when selecting the reference point on the primitive to be adjusted, the point B is selected as the reference point of the primitive to be adjusted for the reference primitive 1, and the point C is selected as the reference point of the primitive to be adjusted for the reference primitive 2.
Referring to fig. 6, the method for generating the adsorption line in step 102 is explained in detail as follows:
as an optional implementation manner, predicting an alignment manner with the at least one reference primitive, and generating a suction line corresponding to the alignment manner respectively includes the following steps:
601, generating a minimum circumscribed rectangle frame of the at least one reference primitive;
In the implementation, there may be a plurality of auxiliary lines corresponding to various alignment manners in step 602, and as an optional implementation, the auxiliary lines include at least one of the following:
a straight line (first auxiliary line) where the left frame of the minimum circumscribed rectangle frame corresponding to the left alignment mode is located;
a straight line (second auxiliary line) where a right frame of the minimum circumscribed rectangle frame corresponding to the right alignment mode is located;
a straight line (third auxiliary line) where the upper frame of the minimum circumscribed rectangle frame corresponding to the upper alignment pattern is located;
a straight line (fourth auxiliary line) on which the lower frame of the minimum bounding rectangle corresponding to the lower alignment mode is located;
a horizontal central line (a fifth auxiliary line) where the central point of the minimum circumscribed rectangle frame corresponding to the horizontal centering alignment mode is located;
and a longitudinal central line (sixth auxiliary line) where the central point of the minimum circumscribed rectangular frame corresponding to the longitudinal centered alignment mode is located.
The six auxiliary lines can assist in achieving the effects of left alignment, right alignment, upper alignment, lower alignment and center alignment between the graphic primitive to be adjusted and the reference graphic primitive, and in practical application, the types of the auxiliary lines can be increased or decreased according to actual needs.
As an optional implementation manner, in step 603, predicting, according to the positions of the primitive to be adjusted and the at least one reference primitive, that the auxiliary line corresponding to the closest alignment manner is the adsorption line includes:
determining a measuring point with the shortest distance to an auxiliary line corresponding to the alignment mode in the graphics primitive to be adjusted according to each alignment mode of each reference graphics primitive in the at least one reference graphics primitive, and calculating the distance between the measuring point and the auxiliary line corresponding to the alignment mode;
and for each reference primitive in the at least one reference primitive, determining the alignment mode corresponding to the shortest distance in the distances as the closest alignment mode, and predicting the auxiliary line corresponding to the closest alignment mode as the adsorption line.
In the embodiment of the invention, if the alignment mode corresponding to the shortest distance is a left alignment mode, determining a first auxiliary line where a left frame of a minimum circumscribed rectangular frame corresponding to the left alignment mode is located as an adsorption line; if the alignment mode corresponding to the shortest distance is the upper alignment mode, the third auxiliary line where the upper border of the minimum circumscribed rectangular frame corresponding to the upper alignment mode is located is determined as the adsorption line, and when the alignment mode corresponding to the shortest distance is the other alignment mode, the method for determining the adsorption line is similar to that, and is not repeated here.
As shown in fig. 7, an embodiment of the present application provides a schematic diagram of an adsorption line in a primitive alignment process, where in a graphics editing page shown in fig. 7, a primitive to be adjusted, a reference primitive 1, and a reference primitive 2 are included, taking three positions of the primitive to be adjusted in a moving process as an example, the position 1 is an initial position of the primitive to be adjusted, when the primitive to be adjusted moves to the position 2, a distance between the primitive to be adjusted and the reference primitive 1 is reduced to a first threshold, and is determined according to a distance between a measurement point in the primitive to be adjusted corresponding to different alignment modes and an auxiliary line in the reference primitive 1, and when an alignment mode corresponding to the shortest distance is a left alignment mode, a first auxiliary line corresponding to the reference primitive is used as the adsorption line, and the adsorption line 1 as shown in the figure is generated on the reference primitive 1;
