[0074] Example 1

[0075] In order to effectively improve drawing efficiency, such as Figure 1 As shown, this embodiment of the invention provides a drawing method based on the Turtle library, including the following steps:

[0076] S11. Obtain drawing settings; the drawing settings include the number of graphics to be drawn in each row of the canvas, the coordinates of the first starting point of the first graphic to be drawn on the canvas, and the horizontal and vertical spacing between adjacent graphics to be drawn.

[0077] In order to arrange multiple graphics to be drawn in a reasonable manner on the drawing canvas, it is necessary to pre-set the number of graphics to be drawn in each row of the canvas (i.e., the number of graphics per row); as well as the coordinates of the first starting point of the first graphic to be drawn on the canvas, the horizontal spacing value between adjacent graphics to be drawn, and the vertical spacing value.

[0078] S12. Obtain the original coordinate data of each of the graphics to be drawn, wherein the original coordinate data includes X-axis data and Y-axis data;

[0079] In addition, it is necessary to obtain the original coordinate data of each graphic to be drawn; in practical applications, if the graphic is drawn based on the original coordinate data of each graphic, the graphic to be drawn may be of different sizes.

[0080] S13. Generate an X list and a Y list based on the original coordinate data of each of the graphics to be drawn; each sublist of the X list is the X-axis dataset in the original coordinate data of each of the graphics to be drawn; each sublist of the Y list is the Y-axis dataset in the original coordinate data of each of the graphics to be drawn; the sublists in the X list and the Y list correspond one-to-one, and two corresponding sublists in the X list and the Y list are the original coordinate data of the same graphics to be drawn;

[0081] To facilitate subsequent coordinate system transformation of the data, the original coordinate data needs to be preprocessed according to the corresponding storage format. In this embodiment of the invention, the original data is stored in a list format.

[0082] S14. Using the drawing settings as parameters, perform calculations and transformations on the data of each sublist in the X list and the Y list according to the preset formula, and convert the original coordinate data in the sublist into drawing coordinate data in the canvas coordinate system.

[0083] After setting the number of graphics in a single row, the coordinates of the first starting point of the first graphic to be drawn on the canvas, and the horizontal and vertical spacing between adjacent graphics to be drawn, the appropriate size and position of each graphic to be drawn after reasonable layout can be obtained (i.e., the number of rows and columns of the graphic to be drawn). In this way, according to the corresponding data conversion formula, the coordinate system can be transformed based on the original data of each graphic to be drawn, and the data values ​​of each graphic to be drawn in the canvas after reasonable layout can be generated.

[0084] In this embodiment of the invention, the method employed is to transform the X-axis data in the X list and the Y-axis data in the Y list respectively. Specific sub-steps may include:

[0085] S21. Based on the number of single-row graphics, the coordinates of the first starting point, and the horizontal and vertical spacing values, determine the uniform width and uniform height of each graphic to be drawn in the canvas.

[0086] After setting the number of single-row graphics, the coordinates of the first starting point of the first graphic to be drawn on the canvas, and the horizontal and vertical spacing between adjacent graphics to be drawn, the first thing that can be determined based on the overall size of the canvas is the uniform width (picture_width) and uniform height (picture_high) of the graphics to be drawn.

[0087] S22. According to the preset formulas: X=kx+b, and Y=k'y+b', perform preliminary calculations and transformations on the X-axis datasets in each sublist of the X list and on the Y-axis datasets in each sublist of the Y list, respectively; wherein:

[0088] The preset formula includes X=kx+b, which is used to perform calculations and transformations on the X-axis datasets in each sublist of the X list; where X is the transformed X-axis data; x is the X-axis data in the original coordinate data; k is the first scaling ratio; b is the horizontal coordinate offset; the first scaling ratio and the horizontal coordinate offset constitute a first transformation parameter combination, and the value of the first transformation parameter combination has a one-to-one correspondence with each sublist of the X list;

[0089] The calculation formula for the value of the first transformation parameter combination corresponding to the sublist in the X list includes:

[0090] The formula for calculating the value of the first scaling factor k of the nth sublist in the X list includes:

[0091] k= picture_width / (max_x[n]-min_x[n]);

[0092] Where, picture_width is the uniform width; max_x[n] is the maximum value of the X-axis data in the nth sublist of the X list; min_x[n] is the minimum value of the X-axis data in the nth sublist of the X list; n is a positive integer starting from 0;

[0093] The formula for calculating the x-coordinate offset b of the nth sublist in the X list includes:

[0094] b= (start_point_X+(n+1) * picture_width +(n-1) *pic_Distance_x)- max_x[n] * k;

[0095] Where start_point_X is the x-coordinate of the first starting point; pic_Distance_x is the horizontal spacing value;

[0096] The preset formula also includes Y=k'y+b', which is used to perform calculations and transformations on the Y-axis datasets in each sublist of the Y list; where Y is the transformed Y-axis data; y is the Y-axis data in the original coordinate data; k' is the second scaling ratio; b' is the ordinate offset; the second scaling ratio and the ordinate offset constitute the second transformation parameter combination, and the value of the second transformation parameter combination has a one-to-one correspondence with each sublist of the Y list;

[0097] The calculation formula for the value of the second transformation parameter combination corresponding to the sublist in the Y list includes:

[0098] The formula for calculating the value of the second scaling factor k' of the nth sublist in the Y list includes:

[0099] k '= picture_high / (max_y[n]-min_y[n])

[0100] Where picture_high is the uniform height; max_y[n] is the maximum value of the Y-axis data in the nth sublist of the Y list; min_y[n] is the minimum value of the Y-axis data in the nth sublist of the Y list; n is a positive integer starting from 0;

[0101] The formula for calculating the x-coordinate offset b' of the nth sublist in the Y list includes:

[0102] b = (start_point_Y+ picture_high )- max_y[n] * k

[0103] Where start_point_Y is the ordinate value of the first starting point; pic_Distance_y is the vertical spacing value;

[0104] S23. Based on the results of the preliminary calculation and transformation, generate the corresponding X' list and Y' list; each sublist of the X' list is the X-axis dataset after the preliminary calculation and transformation; each sublist of the Y' list is the Y-axis dataset after the preliminary calculation and transformation.

[0105] In this embodiment of the invention, a two-stage data conversion method is adopted. After the initial calculation conversion, the scaling conversion is performed to unify the size of each graphic to be drawn. That is, according to the layout setting, each graphic to be drawn is scaled to a suitable size. The data of all graphics to be drawn are preprocessed into a layout arranged in a single line.

[0106] S24. Perform secondary operations and transformations on the data of each sublist in the X' list and the Y' list respectively to generate the final plotting data, wherein:

[0107] The formulas for performing secondary operations on the data in each sublist of the X' list include:

[0108] X'= X - (picture_width + pic_Distance_x)*(m-1)*col_mun;

[0109] Where X' is the X-axis data used as the final drawing data; X is the X-axis data after preliminary calculation and transformation; col_mun is the number of graphics to be drawn in each row of the canvas; m is the row number of the graphics to be drawn corresponding to the sublist in the canvas;

[0110] The formulas for performing secondary operations on the data in each sublist of the Y' list include:

[0111] Y'=Y - (picture_high+pic_Distance_y)*(m-1)

[0112] Where Y' is the Y-axis data used as the final plotting data; Y' is the Y-axis data after preliminary calculation and transformation.

[0113] In this step, position offset is performed through secondary calculations, which can convert each graphic to be drawn into the final drawing data when it is in the correct row and column position, as determined by the drawing settings.

[0114] In practical applications, the specific implementation method for performing preliminary calculation conversion in this embodiment of the invention can be as follows:

[0115] The step involves performing calculations and transformations on the X-axis datasets in each sublist of the X list and the Y-axis datasets in each sublist of the Y list, according to the preset formulas: X=kx+b and Y=k'y+b', including:

[0116] Simultaneously, operations and transformations are performed on the data in each sublist of the X list and the Y list, including:

[0117] The X-axis data of each sublist in the X list are read sequentially, and the updated X-axis data of each sublist are calculated according to the first transformation parameter combination corresponding to the sublist using the preset formula: X=kx+b.

[0118] The Y-axis data of each sublist in the Y list are read sequentially, and the updated Y-axis data of each sublist are calculated according to the second transformation parameter combination corresponding to the sublist using the preset formula: Y=k'y+b'.

[0119] To facilitate establishing a one-to-one correspondence between the first conversion parameter combination and each sublist in the X list, and between the second conversion parameter combination and each sublist in the Y list, in this embodiment of the invention, both the first and second conversion parameter combinations can be stored in list form. Specifically:

[0120] Each of the first conversion parameter combinations is stored in a preset first conversion parameter list, with each list element in the first conversion parameter list being a list element; each list element in the first conversion parameter list corresponds one-to-one with each sublist in the X list;

[0121] Each of the second conversion parameter combinations is stored in a preset second conversion parameter list, with the second conversion parameter combination as a list element; each list element in the first conversion parameter list corresponds one-to-one with each sublist in the Y list.

[0122] Furthermore, in embodiments of the present invention, it may also include:

[0123] S15. Use the drawing command call in the turtle library to convert the drawing coordinate data in the canvas coordinate system and draw on the canvas.

[0124] After the final drawing data is generated, it can be stored in the turtle library. By calling the drawing commands in the turtle library, the graphics to be drawn can be drawn sequentially onto the canvas according to the layout settings.

[0125] In practical software implementation, the graphics in each row of the canvas can be drawn from bottom to top. Each completed row of graphics can be considered a loop, and the drawing of all graphics can be completed through multiple loops. A `break` command can be added to each loop to interrupt the drawing process. When the number of drawings completed in a single loop reaches a set value (i.e., the number of graphics per row), the loop is interrupted; then, the next loop continues to the next row to continue drawing until the drawing is finished. Specifically, this includes:

[0126] After calculating the updated X-axis data of a sublist in the X list and the updated Y-axis data of the sublist in the Y list corresponding to the sublist in the X list, the updated X-axis data and updated Y-axis data are called using the drawing commands in the turtle library, and the corresponding graphic to be drawn is drawn on the canvas.

[0127] When the number of the graphics to be drawn reaches an integer multiple of the number of graphics in a single row, the drawing of the current row is stopped by the break interrupt command and the drawing continues to the next row.

[0128] In summary, in this embodiment of the invention, after obtaining the original coordinate data of each graphic to be drawn, as long as the row and column arrangement of the multiple graphics to be drawn in the computer drawing software is set, the original coordinate data of the multiple graphics to be drawn can be automatically converted into drawing coordinate data in the canvas coordinate system, and each graphic to be drawn can be adjusted to be presented in the canvas with an appropriate image size.

[0129] Because of the embodiments of the present invention, when drawing multiple images on the same canvas, it is no longer necessary to invest a lot of effort in programming multiple times to match the function program of the graphics with the various parameters of the canvas in the Turtle library, thus effectively improving the drawing efficiency.
