[0029] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The present disclosure will be described in detail below with reference to the drawings and embodiments.

[0030] Figure 1 An exemplary system architecture 100 to which the graphic element position adjustment method of the present disclosure can be applied is shown.

[0031] As Figure 1 shown, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 is used to provide a medium for communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, and generally may include wireless communication links and the like.

[0032] The terminal devices 101, 102, 103 interact with the server 105 through the network 104 to receive or send messages and the like. Various communication client applications may be installed on the terminal devices 101, 102, 103, such as instant messaging tools, email clients, etc.

[0033] The terminal devices 101, 102, 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be drawing devices with communication and control functions. The above-mentioned drawing devices can communicate with the server 105. When the terminal devices 101, 102, 103 are software, they can be installed in the above-mentioned terminals.

No specific limitation is made here.

[0034] The server 105 may be a server that provides various services, such as a drawing server that provides support for the drawing systems on the terminal devices 101, 102, 103. The drawing server can analyze and process the relevant information of each terminal in the network, and feedback the processing results (such as the adjusted positions of the graphic elements to be moved, etc.) to the terminal devices.

[0035] It should be noted that the server can be hardware or software.

When the server is software, it can be implemented as multiple software or software modules (such as software or software modules for providing distributed services), or as a single software or software module. No specific limitation is made here.

[0036] It should be noted that the method for adjusting the position of graphic elements provided by the embodiments of the present disclosure is generally executed by the server 105.

[0037] As Figure 2 , a flowchart 200 of an embodiment of the method for adjusting the position of graphic elements according to the present disclosure is shown. The method for adjusting the position of graphic elements includes the following steps:

[0038] Step 201, when moving the graphic element to be moved, obtain the initial position, current position of the actuator, the initial position of the graphic element to be moved, and the position data before movement.

[0039] In this embodiment, the actuator is a device for moving the graphic element to be moved in a graphic editor. For example, the mouse for moving a rectangular graphic element. When moving the graphic element to be moved through the actuator, the actuator first moves from the initial position to the current position. The graphic element to be moved may directly move the same distance as the actuator, or when the automatic adsorption function in the image editor is enabled, if the automatic adsorption condition is met, the graphic element to be moved automatically moves to the target point closest to the graphic element to be moved. The target point can be at the reference line closest to the graphic element to be moved or at the graphic element closest to the graphic element to be moved.

[0040] In this embodiment, the initial position of the graphic element to be moved is the initial position before the graphic element to be moved is affected by the adsorption function of the graphic editor and before one or more movements are performed. The position before movement of the graphic element to be moved is the position of the graphic element to be moved when the execution entity is performing the current movement operation. When the graphic element to be moved has not moved at all, the position before movement of the graphic element to be moved is equal to the initial position of the graphic element to be moved; when the graphic element to be moved has been moved multiple times before performing the current movement, the position before movement of the graphic element to be moved is not equal to the initial position of the graphic element to be moved.

[0041] In this embodiment, the pre-movement position data of the to-be-moved graphic element may include: the position value of the to-be-moved graphic element before movement and the attribute value of the to-be-moved graphic element, and the attribute value of the to-be-moved graphic element can be used to determine the reference line of the to-be-moved graphic element. The attribute value may include: the shape of the to-be-moved graphic element, the length value, width value, line parameters, etc. of the to-be-moved graphic element, where the line parameters are used to characterize the positional relationship between all the reference lines of the to-be-moved graphic element. For example, if the line parameter is 0.5, the vertical distance between any two reference lines of the to-be-moved graphic element needs to be greater than 0.5. For another example, if the pre-movement position data of a to-be-moved graphic element is B1(40, 40, 50, 50), then the position value of the to-be-moved graphic element is (40, 40), the length of the to-be-moved graphic element is 50 cm, and the width of the to-be-moved graphic element is 50 cm.

[0042] In this embodiment, the execution entity of the graphic element position adjustment method (such as Figure 1 the server shown) can obtain the initial position, current position of the actuator, the initial position of the to-be-moved graphic element, and the pre-movement position data in various ways. For example, the execution entity can obtain the initial position, current position of the actuator, the initial position of the to-be-moved graphic element, and the pre-movement position data stored therein from the terminal (such as Figure 1 the terminals 101, 102, 103 shown) through a wired connection method or a wireless connection method. For another example, the user can collect the initial position, current position of the actuator, the initial position of the to-be-moved graphic element, and the pre-movement position data through the terminal (such as Figure 1 the terminals 101, 102 shown). In this way, the execution entity can receive the data collected by the terminal and store these data locally.

[0043] Step 202: Calculate the position offset of the actuator based on the initial position and the current position of the actuator.

[0044] In this embodiment, the position offset of the actuator refers to the displacement of the actuator from the initial position to the current position. For example, if the coordinates of the initial position of the actuator are A1(x, y) and the current position is the coordinates D(x, y), the position offset E(Dx - A1x, Dy - A1y) is calculated according to the coordinates A1(x, y) and the coordinates D(x, y), abbreviated as: E(x, y).

[0045] Step 203: Determine the predicted displacement change amount of the to-be-moved graphic element based on the position offset, the pre-movement position data, and the initial position of the to-be-moved graphic element.

[0046] In this embodiment, the predicted displacement change amount is used to characterize the maximum displacement to be moved when the to-be-moved graphic element is dragged alone by the actuator. The predicted displacement change amount is also the displacement amount that the actuator can act on the to-be-moved graphic element when the adsorption function is enabled in the editor and the to-be-moved graphic element is affected by the adsorption function.

[0047] In some alternative implementation manners of this embodiment, determining the predicted displacement change amount of the to-be-moved graphic element based on the position offset, the position data before movement, and the initial position of the to-be-moved graphic element includes: adding the position offset to the initial position of the to-be-moved graphic element, and subtracting the position value corresponding to the position data before movement to obtain the predicted displacement change amount of the to-be-moved graphic element.

[0048] In this embodiment, the position value corresponding to the position data before movement is the position value corresponding to the to-be-moved graphic element affected by the adsorption function of the editor.

[0049] Specifically, the position data before movement is B1(x, y, w, h), the initial position of the to-be-moved graphic element is M(x, y), and the predicted displacement change amount O(Ex + Mx – B1x, Ey + My – B1y), abbreviated as: O(x, y), can be calculated according to E(x, y) and B1(x, y, w, h), M(x, y).

[0050] In this alternative implementation manner, adding the position offset to the initial position of the to-be-moved graphic element and subtracting the position value corresponding to the position data before movement can effectively predict the maximum displacement that the to-be-moved graphic element can move to under the influence of the adsorption function of the editor, providing a reliable basis for obtaining the predicted displacement change amount.

[0051] Optionally, determining the predicted displacement change amount of the to-be-moved graphic element based on the position offset, the position data before movement, and the initial position of the to-be-moved graphic element includes:

[0052] Determining the position before movement of the to-be-moved graphic element from the position data before movement; subtracting the position before movement of the to-be-moved graphic element from the initial position of the to-be-moved graphic element to obtain the movement distance of the to-be-moved graphic element; adding the movement distance to the position offset to obtain the predicted displacement change amount.

[0053] Optionally, determining the predicted displacement change amount of the to-be-moved graphic element based on the position offset, the position data before movement, and the initial position of the to-be-moved graphic element includes:

[0054] Determining the position before movement of the to-be-moved graphic element from the position data before movement; subtracting the position before movement from the initial position of the to-be-moved graphic element to obtain a displacement difference, and multiplying the displacement difference by the current position of the actuator after dividing by the position offset, so as to estimate and obtain the predicted displacement change amount.

[0055] Step 204, determining the dynamic reference line list of the to-be-moved graphic element based on the position data before movement of the to-be-moved graphic element.

[0056] In this embodiment, after the adsorption function of the graphics editor for editing the to-be-moved primitive is turned on, the reference lines of each primitive in the graphics editor can be calculated, and the reference lines can be determined based on the reference line calculation rules preset in the graphics editor. Among them, the reference line calculation rules can be: calculating horizontal alignment, calculating vertical alignment, calculating the center line, etc. Among them, the dynamic reference line list is the reference line of the to-be-moved primitive obtained from the pre-movement position data.

[0057] For example, the data A(x, y, w, h) of a primitive is (0, 0, 100, 100), and the reference lines obtained through the reference line calculation rules include: A1 horizontal line, A2 horizontal line, B1 vertical line, B2 vertical line.

[0058] In this embodiment, the to-be-moved primitive is the primitive that needs to be moved. Through the reference line calculation rules, all the reference lines of the to-be-moved primitive can be obtained; and during the movement of the to-be-moved primitive, all the reference lines corresponding to the to-be-moved primitive can also be calculated in real time, all the reference lines corresponding to the to-be-moved primitive.

[0059] Step 205: Based on the dynamic reference line list, the predicted displacement change amount, and the pre-movement position data, determine the adjustment position, and adjust the to-be-moved primitive to the adjustment position.

[0060] In this embodiment, the adjustment position is the position where the to-be-moved primitive actually needs to move. This adjustment position is the position obtained based on the pre-movement position in the predicted displacement change amount and the pre-movement position data after excluding the adsorption influence of the dynamic reference line list on the to-be-moved primitive.

[0061] In some optional implementation manners of this embodiment, the above determining the adjustment position based on the dynamic reference line list, the predicted displacement change amount, and the pre-movement position data includes: calculating an adjustment offset based on the dynamic reference line list and the predicted displacement change amount; calculating the adjustment position based on the adjustment offset and the pre-movement position data.

[0062] In this optional implementation manner, the adjustment offset is the amount that the to-be-moved primitive needs to offset when it is at the position corresponding to the pre-movement position data.

[0063] In this optional implementation manner, by calculating the adjustment offset through the predicted displacement change amount and the pre-movement position data, and then obtaining the adjustment position from the adjustment offset, the calculation of the adjustment position can be simply and conveniently realized, improving the accuracy of the movement of the to-be-moved primitive.

[0064] Optionally, after obtaining the adjustment position, adjustment data can be calculated based on the adjustment position (that is, adding the attribute value of the to-be-moved primitive on the basis of the adjustment position), and the adjustment data can be used as the new pre-movement position data, thereby providing a basis for the next adjustment of the to-be-moved primitive.

[0065] In another alternative implementation of this embodiment, calculating the adjustment offset based on the dynamic reference line list and the predicted displacement change amount includes: generating a static reference line list based on all the graphic elements in the static layer of the graphic editor; respectively selecting the closest dynamic reference line and static reference line to the graphic element to be moved from the dynamic reference line list and the static reference line list based on the dragging direction corresponding to the predicted displacement change amount; and in response to determining that the absolute value of the difference between the distance between the dynamic reference line and the static reference line and the predicted displacement change amount is greater than the preset adsorption distance value, taking the predicted displacement change amount as the adjustment offset.

[0066] In this alternative implementation, the layer where the graphic element to be moved is located is a dynamic layer, which is the layer where the execution subject is currently operating, and the layers other than the dynamic layer in the graphic editor are all static layers. The reference lines of each graphic element can be obtained based on all the graphic elements in the static layer of the graphic editor, and the reference lines of all the graphic elements in all the static layers are combined to obtain the static reference line list. Specifically, as shown in Table 1 and Table 2, Table 1 is the data of the graphic elements in the static layer, and Table 2 is the static reference line list L.

[0071] As Figure 3 shown, according to the moving direction of O(x, y), match the two closest reference lines F1 (the dynamic reference line in the dynamic reference line list L1) and N1 (the static reference line in the dynamic reference line list L) to the static reference line list L in this moving direction from the dynamic reference line list L1, and the position corresponding to the predicted displacement change amount is Figure 3 the position corresponding to F2 in. The distance between F1 and N1 is P, the distance between F2 and F1 is M, M corresponds to O(x, y), and M can be Ox or Oy.

[0072] If the absolute value of the difference between P - Ox or P - Oy is greater than the preset adsorption distance value (that is, the graphic element to be moved will not be affected by the adsorption force of the reference line), then directly take O(x, y) as the adjustment offset without processing.

[0073] In this alternative implementation, by obtaining the closest static reference line and static reference line to the graphic element to be moved, it can be determined whether the predicted displacement change amount is affected by the adsorption force of the reference line, so as to effectively determine the adjustment offset of the graphic element to be moved.

[0074] Optionally, calculating the adjustment offset based on the dynamic reference line list and the predicted displacement change amount includes: generating a static reference line list based on all the graphic elements in the static layer of the graphic editor; respectively selecting the closest dynamic reference line and static reference line to the graphic element to be moved from the dynamic reference line list and the static reference line list based on the dragging direction corresponding to the predicted displacement change amount; in response to determining that the absolute value of the sum of the dynamic reference line minus the static reference line coordinates and the predicted displacement change amount is greater than a preset adsorption distance value, taking the predicted displacement change amount as the adjustment offset.

[0075] In this optional manner, if the absolute value of the difference between N1 and (F1 + Ox) or (F1 + Oy) is greater than the preset adsorption distance value, then O(x, y) is directly taken as the adjustment offset without processing.

[0076] In some optional implementation manners of this embodiment, calculating the adjustment offset based on the dynamic reference line list and the predicted displacement change amount includes: generating a static reference line list based on all the graphic elements in the static layer of the graphic editor; respectively selecting the closest dynamic reference line and static reference line to the graphic element to be moved from the dynamic reference line list and the static reference line list based on the dragging direction corresponding to the predicted displacement change amount; in response to determining that the absolute value of the difference between the distance between the dynamic reference line and the static reference line and the predicted displacement change amount is less than or equal to the preset adsorption distance value, obtaining the adjustment offset based on the distance value between the dynamic reference line and the static reference line.

[0077] In this optional implementation manner, if the absolute value of the difference between P and Ox or P and Oy is less than or equal to the preset adsorption distance value (that is, the graphic element to be moved is affected by the adsorption force of the reference line), then the adjustment offset is obtained based on P. For example, the adjustment offset is T(N1x - F1x, N1y - F1y). It should be noted that: the adsorption has a direction. If there is no adsorption in one direction and there is adsorption in the other direction, then only the adjustment offset in the direction with adsorption is calculated. For example, if the graphic element to be moved only adsorbs the vertical reference line, then the adjustment offset is T(N1x - F1x, Oy).

[0078] In this optional implementation manner, by obtaining the closest static reference line and dynamic reference line to the graphic element to be moved, the distance value corresponding to the influence of the predicted displacement change amount by the adsorption force of the reference line is determined, thereby effectively determining the adjustment offset of the graphic element to be moved.

[0079] Optionally, calculating the adjustment offset based on the dynamic reference line list and the predicted displacement change amount includes: generating a static reference line list based on all the graphic elements in the static layer of the graphic editor; respectively selecting the dynamic reference line and the static reference line closest to the graphic element to be moved from the dynamic reference line list and the static reference line list based on the dragging direction corresponding to the predicted displacement change amount; in response to determining that the absolute value of the sum of the coordinates of the dynamic reference line minus the static reference line and the predicted displacement change amount is less than or equal to the preset adsorption distance value, obtaining the adjustment offset based on the distance value between the dynamic reference line and the static reference line.

[0080] In this optional method, if the absolute value of the difference between N1 and (F1 + Ox) or (F1 + Oy) is less than or equal to the preset adsorption distance value, the adjustment offset is obtained based on P. For example, the adjustment offset is T(N1x - F1x, N1y - F1y). It should be noted that adsorption has a direction. If there is no adsorption in one direction and adsorption in the other direction, only the adjustment offset in the direction with adsorption is calculated. For example, if the graphic element to be moved only adsorbs the vertical reference line, the adjustment offset is T(N1x - F1x, Oy).

[0081] The graphic element position adjustment method provided by the embodiments of the present disclosure first obtains the initial position, current position, initial position of the graphic element to be moved, and position data before movement of the actuator when moving the graphic element to be moved; secondly, calculates the position offset of the actuator based on the initial position and current position of the actuator; thirdly, determines the predicted displacement change amount of the graphic element to be moved based on the position offset, position data before movement, and initial position of the graphic element to be moved; fourthly, determines the dynamic reference line list of the graphic element to be moved based on the position data before movement of the graphic element to be moved; finally, determines the adjustment position based on the dynamic reference line list, predicted displacement change amount, and position data before movement, and adjusts the graphic element to be moved to the adjustment position. Thus, based on the position offset of the actuator, the initial position of the graphic element to be moved, and the position data before movement of the graphic element to be moved, the adjustment position of the graphic element to be moved is obtained, realizing the reference adsorption function of separately splitting out the reference line. Without considering its own business logic, different systems or technologies can quickly access the reference adsorption function, so that based on the parameter passing requirements of the reference adsorption function, the reference line data can be quickly obtained, improving the development efficiency of the reference line and the user experience.

[0082] In this embodiment, after generating a static reference line list for all graphic elements in the static layer based on the graphic editor, the static reference line list and the dynamic reference line list can be matched to obtain matching reference lines; the matching reference lines are displayed. In this embodiment, the matching reference lines are obtained by comparing the reference lines in the static reference line list with the reference lines in the dynamic reference line list one by one for similarity. In response to determining that the similarity between two reference lines is greater than the similarity threshold (e.g., 90%), any one of the two reference lines is used as a matching reference line. Please refer to Figure 4 , which shows the flowchart 400 of another embodiment of the graphic element position adjustment method provided by the present disclosure. The graphic element position adjustment method may include the following steps:

[0083] Step 401, when moving a graphic element to be moved, obtain the initial position, current position of the actuator, the initial position of the graphic element to be moved, and the position data before movement.

[0084] Step 402, calculate the position offset of the actuator based on the initial position and the current position of the actuator.

[0085] Step 403, determine the predicted displacement change amount of the graphic element to be moved based on the position offset, the position data before movement, and the initial position of the graphic element to be moved.

[0086] Step 404, determine the dynamic reference line list of the graphic element to be moved based on the position data before movement of the graphic element to be moved.

[0087] It should be understood that the operations and features in the above steps 401 - 404 respectively correspond to the operations and features in steps 101 - 104. Therefore, the descriptions of the operations and features in the above steps 101 - 104 also apply to steps 401 - 404 and will not be repeated here.

[0088] Step 405, generate a static reference line list based on all graphic elements in the static layer of the graphic editor.

[0089] In this embodiment, the layer where the graphic element to be moved is located is a dynamic layer, and the layers other than the dynamic layer in the graphic editor are all static layers. The reference lines of each graphic element can be obtained based on all graphic elements in the static layer of the graphic editor, and the reference lines of all graphic elements in all static layers are combined to obtain a static reference line list, as specifically shown in Table 1 and Table 2. Table 1 is the data of the graphic elements in the static layer, and Table 2 is the static reference line list L.

[0090] As shown in Table 3 is the data of the graphic element to be moved in the dynamic layer, and Table 4 is the dynamic reference line list L1.

[0094]

[0095]

[0096] Step 406: Match the static reference line list and the dynamic reference line list to obtain the matching reference line.

[0097] In this embodiment, after matching L1 and L, matching data is obtained and the matching data is returned. The matching reference line can be drawn through the matching data. For example, when matching the reference lines in Table 2 and Table 4, C2 and A2, C4 and A4 can be matched. Then, C2 and C4 can be used as the matching reference line, or A2 and A4 can be used as the matching reference line.

[0098] Step 407: Display the matching reference line.

[0099] In this embodiment, the matching reference line can be a static reference line in the static reference line list or a dynamic reference line in the dynamic reference line list, and the matching reference line can be displayed after moving the to-be-moved graphic element and after moving the to-be-moved graphic element.

[0100] Step 408: Based on the dragging direction corresponding to the predicted displacement change amount, respectively select the dynamic reference line and the static reference line closest to the to-be-moved graphic element from the dynamic reference line list and the static reference line list.

[0101] Step 409: In response to determining that the absolute value of the difference between the distance between the dynamic reference line and the static reference line and the predicted displacement change amount is greater than the preset adsorption distance value, use the predicted displacement change amount as the adjustment offset.

[0102] Step 410: Based on the adjustment offset and the position data before movement, calculate the adjusted position and adjust the to-be-moved graphic element to the adjusted position.

[0103] In an example, the predicted displacement change amount of a to-be-moved graphic element is O(3, 3), and the position data before movement is B1(34, 17, 100, 100). Based on the data before movement, the dynamic reference line list is shown in Table 5. By matching the static reference line list in Table 2, the two reference lines B3 and F3 with the closest distance can be obtained. The sum of F3 and Ox is 37. At this time, the difference 40 - 37 < 5 (the preset adsorption distance value), meeting the adsorption requirement. At this time, the adjustment offset obtained is T(40 - 34, 3), that is, T(6, 3).

[0106]

[0107] Using the graphic element position adjustment method provided in this embodiment to obtain the reference line module, only the basic data and coordinate information required by the reference line module need to be given to complete the reference line matching and the calculation of the adjusted position. That is, two initial information, namely the initial position of the actuator and the initial position of the graphic element to be moved, are given to the reference line module, and subsequently, only the current coordinates of the actuator and the current position of the graphic element to be moved are required to complete the calculation of the adjusted position.

[0108] In the process of adjusting the graphic element to be moved, the graphic element position adjustment method provided in this embodiment matches the static reference line list with the dynamic reference line list to obtain the matching reference line, and displays the matching reference line, which can display in real time the matching reference line of the graphic element to be moved when moving and matching with the static reference lines of the static layer, providing a reliable hint for the user to draw a graph.
