Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Fig. 1 is a flowchart of an object placement method based on layout design according to the present invention, and the object placement method based on layout design according to the present invention will be described in detail with reference to fig. 1.
First, in step 101, a put command is initiated. In this step, a placing command containing this function is started, ensuring that the function can be used normally when an object is placed.
In step 102, coordinate information of the object to be placed recorded in the shear plate is read. In this step, when a placing command is initiated, the command functions to read coordinate information of an object to be placed in the clipboard.
In step 103, it is determined whether the function option of calculating relative position is turned on, if yes, step 104 is performed, otherwise step 105 is skipped. In the step, after the shape display of the actual object is started, a stage of selecting a placing mode is entered, and whether a corresponding switch is started or not is read to determine whether an algorithm for keeping a relative position or an algorithm for using a squared figure is used.
In step 104, the positional relationship between the placement point and the object to be placed is determined. In this step, a relative position preserving algorithm is used.
Preferably, the parameter information of the object to be placed in the clipboard is searched through the query function. In this step, the algorithm for maintaining the relative position searches for various types of parameter information of the object to be placed in the clipboard through the query function, such as type information of the object, coordinate point information of the object, object level information, and the like.
Preferably, a point function is used for obtaining coordinate point information of the object by taking out the query function, and a value x of the central coordinate of the object to be placed is obtainedObjectAnd yObjectReading the coordinate value x of the origin in the coordinate system of the object to be placedOrigin pointAnd yOrigin pointAnd storing the data into an array, and calculating the relative position of the object to be placed and the original point in the coordinate system by using a distance calculation formula after obtaining the data of the required point:
preferably, after the distance is obtained, the coordinate values of the object to be placed and the origin are compared respectively so as to determine the direction of the origin relative to the object to be placed, then the object obtained by query is placed in the object layout during placement, then the placement reference point is adjusted to replace the coordinate origin of the coordinate system where the object to be placed is located, and the adjusted placement reference point and the object to be placed still keep the relative position and distance obtained through calculation. In this step, the actual effect is equivalent to taking out the actual position relationship between the object and the origin and performing the moving operation, and the placement reference point coincides with the origin of the coordinate system where the object to be placed is located (at this time, the position relationship of the placement reference point of the object is equal to the position relationship between the origin and the object in the coordinate system where the object is located).
Fig. 2 is a schematic diagram of placing an object by applying a relative position relationship according to the present invention, as shown in fig. 2, the present invention places an object by applying a relative position relationship, and if the above condition is required to be satisfied, we only need to ensure that the relative position distance from the center point of the a object to be placed to the coordinate origin of the coordinate system of the a object satisfies the requirement (when a special relative position between the a object and the object is required to be considered during placement in a general Layout, an object meeting the condition with the origin is generally made).
After the function is started, various kinds of parameter information of the A object are obtained through a query function, then a center coordinate point of the A and an origin coordinate of a coordinate system where the A object is located are taken out through a point function, an actual distance between the A object and the origin coordinate is calculated through a distance formula, the A object is placed into the actual object, a placement reference point of the A object is adjusted to be overlapped with the origin coordinate of the coordinate system where the A object is located and replace the origin coordinate, the placement reference point keeps a relative position relation with the A object, the relative position relation between the A object and the placement reference point is called in a layout where the B object is located, and finally the relative position relation condition between the A object and the B object can be met by directly moving the placement reference point to a lower left corner point (a point needing to be placed) of the B object through a mouse, and the.
In step 105, a placement point is set on the object Bbox according to the squared figure. In this step, a Sudoku algorithm is used to adjust an object placement reference point within the object Bbox. As shown in fig. 3, by using the placing manner of the nine-square grid in the prior art, the distance between the upper right corner of the object a and the lower left corner of the object B needs to be 1 in the negative Y direction and 0.5 in the left X direction, a placing point needs to be found by using a measuring means, and then the placing reference point of the object a (adjusted to the upper right corner of the object a, and then the placing reference point of the object is moved to the point to be placed (coinciding with the placing reference point) to be placed by using the nine-square grid, which is complicated in process.
At step 106, the placement point is moved to the desired placement point for placement and ends.
The invention provides an object placing method based on layout design, which aims to solve the problem that when an object is placed by using a Sudoku method, a short plate which is complicated in process of considering the relative position relation of surrounding objects is needed, when a corresponding function is started, the object to be placed can meet the relative position relation with the rest object, the position coordinates of the object are detected firstly, and then the relative position relation with the original point is calculated after coordinate points of the object are obtained. Therefore, the relative position relationship between the actual object and the placing reference point when the function is started is determined (the placing reference point of the object is coincident with the original point of the object relative position after the function is started), and the purpose can be quickly achieved by using the function under the condition that the special relative position between the actual object and the object needs to be considered when the actual object is placed in the Layout of.
To achieve the above object, the present invention further provides a computer-readable storage medium, on which a computer program is stored, which when executed performs the steps of the layout design based object placement method as described above.
In order to achieve the above object, the present invention further provides an object placing apparatus based on layout design, including a memory and a processor, where the memory stores a computer program running on the processor, and the processor executes the steps of the object placing method based on layout design as described above when running the computer program.
