Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a node scaling method, device, equipment and storage medium. Background Art

[0002] In today's digital age, graphical user interfaces play a vital role in various software applications. In many graphical user interface applications, canvas is a common element, which is used to display and edit various graphic objects, such as text, images, shapes, etc. However, when there are a large number of graphic objects on the canvas or the size is large, the display may be incomplete or difficult to operate.

[0003] In the prior art, scaling nodes in the canvas usually adopts a fixed-ratio scaling or a free-ratio scaling input by the user. However, in the fixed-ratio scaling method, users can only choose preset scaling ratios, such as 1:1, 2:1, etc., which has poor flexibility and cannot meet the user's needs for different scaling ratios. Free scaling means that users can freely adjust the scaling ratio through mouse wheel or gesture operation, but this method may cause users to misoperate or it is difficult to accurately control the scaling ratio. After the nodes are scaled, they are easy to overflow the canvas, and the user's visual coordination cannot be guaranteed. Summary of the invention

[0033] Embodiment 1

[0034] Figure 1 A flowchart of a node scaling method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of using antv / G6 to draw pictures. The method can be executed by a node scaling device. The node scaling device can be implemented in the form of hardware and / or software. The node scaling device can be configured in a computer controller. Figure 1 As shown, the method includes:

[0035] S110: Determine a target node in the canvas, obtain node information based on the target node, and obtain canvas information.

[0036] The canvas refers to a virtual plane or area used to carry various graphics, elements, etc. The target node refers to a specific element in the canvas that is specially selected and needs to be operated or analyzed. The node information refers to the size and position information related to the target node. The canvas information refers to the information related to the canvas size.

[0037] Specifically, the controller determines the target node in the current canvas, which is the core object for subsequent zoom operations. Then, the controller obtains node information and canvas information based on the target node, including node width, node height, and target spacing value. Canvas information includes canvas width and canvas height.

[0038] Optionally, node information is obtained based on the target node, and canvas information is obtained, including: obtaining node width and node height based on the target node, and obtaining canvas width, canvas height and each canvas edge position; determining the spacing value from the target node to each canvas edge position, and taking the minimum spacing value among the spacing values ​​as the target spacing value; taking the node width, node height and target spacing value as node information, and taking the canvas width and canvas height as canvas information.

[0039] Specifically, the controller will obtain the width of the target node, that is, the size of the node in the horizontal direction, and the height of the target node, that is, its size in the vertical direction. At the same time, the controller will also obtain canvas information, including canvas width, that is, the size range of the entire canvas in the horizontal direction, canvas height, that is, the range in the vertical direction; and the specific positions of each edge of the canvas, such as the coordinates or limits of the top edge, bottom edge, left edge, and right edge. The controller will then determine the spacing value from the target node to each edge of the canvas, and find the smallest value from these spacing values ​​as the target spacing value. The target spacing value represents the minimum distance between the target node and the edge of the canvas.

[0040] S120 . Determine a width scaling ratio and a height scaling ratio according to the node information and the canvas information.

[0041] The width scaling ratio refers to the scaling factor of the target node in the horizontal direction, which is used to determine the scaling degree of the target node in width. The height scaling ratio refers to the scaling factor of the target node in the vertical direction, which determines the scaling extent of the target node in height.

[0042] Specifically, the controller will calculate the width scaling ratio and the height scaling ratio according to the acquired node information and canvas information using corresponding algorithms or rules. These two ratios will reflect the degree of scaling required in the width and height directions.

[0043] Optionally, determining the width scaling ratio and the height scaling ratio based on the node information and the canvas information includes: determining a first difference between the canvas width and the target spacing value, and determining a second difference between the canvas height and the target spacing; determining the width scaling ratio based on the node width and the first difference; determining the height scaling ratio based on the node height and the second difference.

[0044] Specifically, the controller determines a first difference between the width of the canvas and the target spacing value, and a second difference between the height of the canvas and the target spacing value, that is, the first difference is obtained by subtracting the target spacing value from the width of the canvas, and the second difference is obtained by subtracting the target spacing value from the height of the canvas. Then, the width scaling ratio is further determined according to the node width and the first difference, and the height scaling ratio is determined according to the node height and the second difference.

[0045] Optionally, determining the width scaling ratio based on the node width and the first difference includes: judging whether the node width is greater than the first difference, and if so, determining a first ratio of the first difference and the node width, and using the first ratio as the width scaling ratio; otherwise, determining the width scaling ratio to be 1.

[0046] Specifically, the controller compares the node width with the first difference. If it is determined that the node width is greater than the first difference, then a first ratio of the first difference to the node width needs to be further determined, and the first ratio is used as the width scaling ratio. However, if the node width is not greater than the first difference, then the width scaling ratio is directly determined to be 1. 1 means that the width of the target node in the current canvas does not need to be scaled, and only needs to maintain the original width state.

[0047] Optionally, the height scaling ratio is determined based on the node height and the second difference, including: determining whether the node height is greater than the second difference, if so, determining a second ratio of the second difference and the node height, and using the second ratio as the width scaling ratio; otherwise, determining the height scaling ratio to be 1.

[0048] Specifically, the controller compares the node height with the second difference. If it is determined that the node height is greater than the second difference, then it is necessary to further determine the second ratio of the second difference to the node height, and use the second ratio as the height scaling ratio. However, if the node height is not greater than the second difference, then the height scaling ratio is directly determined to be 1. 1 means that the height of the target node in the current canvas does not need to be scaled, and only needs to maintain the original height state.

[0049] S130 , determining a target scaling ratio according to the width scaling ratio and the height scaling ratio, and scaling the target node according to the target scaling ratio.

[0050] Specifically, the controller will comprehensively consider the width scaling ratio and the height scaling ratio, and then determine a final target scaling ratio. The target scaling ratio is a unified ratio obtained by combining the scaling requirements in two directions. Finally, the controller will perform a scaling operation on the previously determined target node according to the determined target scaling ratio. By comprehensively considering the width scaling ratio and the height scaling ratio to scale the nodes in the canvas, it can be ensured that the nodes still maintain their original shape ratio after scaling, and will not be distorted, making the entire picture or layout more coordinated and beautiful, and avoiding overflow of the canvas after node scaling, and avoiding the rationality and logic of the overall layout being destroyed due to improper scaling in a single direction.

[0051] Optionally, determining the target scaling ratio according to the width scaling ratio and the height scaling ratio includes: judging whether the width scaling ratio is greater than the height scaling ratio, and if so, taking the height scaling ratio as the target scaling ratio; otherwise, taking the width scaling ratio as the target scaling ratio.

[0052] Specifically, the controller compares the two ratios, that is, determines whether the width scaling ratio is greater than the height scaling ratio. If the width scaling ratio is greater than the height scaling ratio, then the height scaling ratio is selected and determined as the target scaling ratio. However, if it is determined that the width scaling ratio is not greater than the height scaling ratio, then the width scaling ratio is determined as the target scaling ratio. That is, the smaller value of the width scaling ratio and the height scaling ratio is used as the target scaling ratio. By comprehensively considering the width scaling ratio and the height scaling ratio, the nodes can be scaled more comprehensively to adapt to different canvas sizes and layout requirements. This ensures that the nodes can maintain the appropriate ratio and size after scaling, thereby presenting a better effect in the canvas.

[0053] The technical solution of the embodiment of the present invention determines the width scaling ratio and the height scaling ratio by combining the node information and the canvas information, and determines the target scaling ratio by comprehensively considering the width scaling ratio and the height scaling ratio, and automatically performs a scaling operation on the target node, which can ensure that the node still maintains the original shape ratio after scaling and will not be distorted, making the entire picture or layout more coordinated and beautiful, better meeting the needs of users, avoiding the overflow of the canvas after the node is scaled, and also avoiding the destruction of the rationality and logic of the overall layout due to improper scaling in a single direction.

[0054] Embodiment 2

[0055] Figure 2 This is a flowchart of a node scaling method provided in the second embodiment of the present invention. This embodiment adds a specific process of determining the target node in the canvas based on the above-mentioned first embodiment. Among them, the specific content of steps S260-S270 is roughly the same as steps S120-S130 in the first embodiment, so they will not be repeated in this embodiment. Figure 2 As shown, the method includes:

[0056] S210: Determine each node in the canvas, and number each node in sequence to generate numbered nodes.

[0057] S220, determine whether the target number input by the user is received, if so, execute S230, otherwise, execute S240.

[0058] S230. Set the node corresponding to the target number as the target node.

[0059] S240: taking the numbered nodes as target nodes in sequence according to the numbering order.

[0060] Specifically, the controller will identify the entire canvas to obtain all the nodes therein. Then, in order to facilitate subsequent operations and management, the controller will number each of these identified nodes in turn. The controller determines the target node in two ways, one is to use the user-specified node as the target node, and the other is to use each node as the target node in sequence according to the numbering order. The controller will determine whether the target number entered by the user has been received. If the target number entered by the user is received, then the node corresponding to the target number is found from the numbered nodes as the target node. However, if the target number entered by the user is not received, then each numbered node will be processed as a target node in sequence according to the previously generated numbering order.

[0061] S250: Obtain node information based on the target node, and obtain canvas information.

[0062] Optionally, node information is obtained based on the target node, and canvas information is obtained, including: obtaining node width and node height based on the target node, and obtaining canvas width, canvas height and each canvas edge position; determining the spacing value from the target node to each canvas edge position, and taking the minimum spacing value among the spacing values ​​as the target spacing value; taking the node width, node height and target spacing value as node information, and taking the canvas width and canvas height as canvas information.

[0065] Optionally, determining the width scaling ratio based on the node width and the first difference includes: judging whether the node width is greater than the first difference, and if so, determining a first ratio of the first difference and the node width, and using the first ratio as the width scaling ratio; otherwise, determining the width scaling ratio to be 1.

[0066] Optionally, the height scaling ratio is determined based on the node height and the second difference, including: determining whether the node height is greater than the second difference, if so, determining a second ratio of the second difference and the node height, and using the second ratio as the width scaling ratio; otherwise, determining the height scaling ratio to be 1.

[0067] S270: Determine a target scaling ratio according to the width scaling ratio and the height scaling ratio, and scale the target node according to the target scaling ratio.

[0068] Optionally, determining the target scaling ratio according to the width scaling ratio and the height scaling ratio includes: judging whether the width scaling ratio is greater than the height scaling ratio, and if so, taking the height scaling ratio as the target scaling ratio; otherwise, taking the width scaling ratio as the target scaling ratio.

[0069] The technical solution of the embodiment of the present invention determines the width scaling ratio and the height scaling ratio by combining the node information and the canvas information, and determines the target scaling ratio by comprehensively considering the width scaling ratio and the height scaling ratio, and automatically performs a scaling operation on the target node, which can ensure that the node still maintains the original shape ratio after scaling and will not be distorted, making the entire picture or layout more coordinated and beautiful, better meeting the needs of users, avoiding the overflow of the canvas after the node is scaled, and also avoiding the destruction of the rationality and logic of the overall layout due to improper scaling in a single direction.
