Description

Technical Field

[0001] This invention relates to the field of computers, and in particular to a visual modification method, apparatus, and related components for cutting and modifying files. Background Technology

[0002] Currently, generating traditional screen cutting files requires specialized drawing software. After obtaining the cutting file, the die-cutting machine performs the cutting operation on the screen protector according to the input cutting file.

[0003] If there are data errors in the cutting file during this cutting process (due to unadjusted dimensions or hardware damage), the processed mobile phone screen protector will be scrapped, seriously affecting production efficiency and yield. Therefore, the cutting outline of the cutting file needs to be checked before cutting. If any deviation is found, the cutting file needs to be modified accordingly to meet the user's needs.

[0004] However, modifying the cut files using professional drawing software is a complex and time-consuming process, requiring personnel with certain drawing skills, which is quite troublesome. In other words, mobile users face the problem of not being able to quickly modify and create cut files themselves. Summary of the Invention

[0005] The purpose of this invention is to provide a visual modification method, apparatus, and related components for cutting files, aiming to solve the problem that mobile users cannot quickly modify and create cut files.

[0006] To solve the above-mentioned technical problems, the objective of this invention is achieved through the following technical solution: providing a visual modification method for cutting files, comprising:

[0007] Read the cut file and extract the path array of the cut file, wherein the path array contains multiple paths and each path contains multiple path marking points;

[0008] Create a Canvas and draw the path array on the Canvas to obtain the cutting outline;

[0009] The cutting contour is modified and output according to the preset selection rules.

[0010] Furthermore, the technical problem to be solved by the present invention is to provide a visual modification device for cutting documents, which includes:

[0011] A reading unit is used to read a cut file and extract a path array from the cut file, wherein the path array contains multiple paths and each path contains multiple path marking points;

[0012] A drawing unit is used to create a Canvas and draw the path array on the Canvas to obtain the cutting outline;

[0013] The modification unit is used to modify and output the cutting contour according to a preset selection rule.

[0014] In addition, this embodiment of the invention provides a computer device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the visual modification method for cutting files described in the first aspect above.

[0015] In addition, embodiments of the present invention also provide a computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, causes the processor to perform the visual modification method for cutting files described in the first aspect above.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0027] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0028] Please see Figure 1 , Figure 1 A flowchart illustrating the visual modification method for cutting files provided in an embodiment of the present invention;

[0029] like Figure 1 As shown, the method includes steps S101 to S103.

[0030] S101. Read the cut file and extract the path array of the cut file, wherein the path array contains multiple paths and the path contains multiple path marking points;

[0031] S102. Create a Canvas and draw the path array on the Canvas to obtain the cutting outline;

[0032] S103. Modify and output the cutting contour according to the preset selection rules.

[0033] In this embodiment, before the cutting file is input into the film cutting machine, the mobile user receives the cutting file using their mobile device. After receiving the input information for the cutting file, the application reads the cutting file and extracts the path array within it, for example... Figure 2 As shown, one path array includes 5 paths, and each path is formed by connecting multiple path inscription points. It should be noted that the path in this application is formed by multiple path inscription points forming a closed loop. In actual cases, the path can also be defined as extending from a starting point in one direction, so this embodiment will not elaborate further.

[0034] Since the cutting file consists of a series of x and y coordinates, such as (PD0, 3; PU3, 4; PD5, 6), where PD represents cutting down and PU represents cutting up, the command "PD x, y" means cutting down first and then moving to the (x, y) coordinate; the command "PU x, y" means cutting up first and then moving to the (x, y) coordinate. Directly opening the cutting file makes it impossible to see where the size of the cutting contour is too large or the position is off. Therefore, this application first creates a Canvas, then draws the path array on the Canvas, thereby making the cutting contour in the cutting file visible and convenient for users to view. Finally, the cutting contour is modified and output according to the preset selection rules.

[0035] In this embodiment, in order to solve the problems in the prior art that modifying the cutting file requires personnel with professional drawing knowledge, and that modifying the cutting contour in existing drawing software is cumbersome and time-consuming, the visual modification method for cutting files provided in this application can visualize the cutting contour on a mobile device, thereby making it convenient for users to check whether the cutting contour meets the requirements. If it does not meet the requirements, the cutting contour can be directly modified and output according to the preset selection rules, which is simple and convenient to operate.

[0036] In one specific embodiment, step S102 includes the following steps:

[0037] S10. Obtain the preset Canvas properties and create a Canvas based on the Canvas properties;

[0038] S11. Obtain the position coordinates of all the path inscription points, and based on the preset screen coordinate system on the Canvas, draw all the path inscription points at the corresponding positions on the Canvas to obtain the cutting contour.

[0039] In this embodiment, the Canvas properties can be pre-configured, such as the length and width of the Canvas, the background color of the Canvas, and the transparency of the Canvas, so that the cutting outline can be clearly displayed on the Canvas. Since each path inscription point has its own coordinate position information, the cutting outline can be drawn on the corresponding position of the Canvas according to the actual size of the cutting outline according to the position coordinates of each path inscription point. This application establishes a screen coordinate system on the Canvas, wherein the origin of the screen coordinate system is set at the lower left corner of the Canvas.

[0040] In one specific embodiment, step S103 includes the following steps:

[0041] S20. Based on the user's selection command, select the target path in the cutting contour;

[0042] S21. Based on the user's modification command, perform a modification operation on the target path;

[0043] S22. After all modification operations are performed, update the path array and output the target split file.

[0044] In this embodiment, after the user checks the displayed cutting contour, if some paths need to be modified, the user selects the paths based on the user's selection command. After the path is selected, the length of the selected path is adjusted and modified according to the actual size of the cutting contour. After checking the entire cutting contour and making corresponding modifications, a new path array is obtained. The new path array is stored or directly overwrites the original cutting file to obtain the target cutting file and output it.

[0045] like Figure 3 As shown, in one specific embodiment, step S20 includes the following steps:

[0046] S30. Calculate the distance data between each of the path marking points and the edge line of the Canvas to obtain a distance data sequence;

[0047] S31. Traverse the distance data sequence and extract the baseline path marking point corresponding to the distance data with the smallest value;

[0048] S32. Based on the preset judgment rules, determine whether the minimum distance data is greater than the distance threshold. If the minimum distance data is greater than the distance threshold, then execute step S33. If the minimum distance data is less than the distance threshold, then execute step S34.

[0049] S33. Perform a proportional scaling operation on the canvas to make the updated minimum distance data of the reference path inscription points equal to the distance threshold.

[0050] S34. Perform a proportional scaling operation on the canvas so that the minimum distance data of the updated reference path plotting points is equal to the distance threshold.

[0051] In this embodiment, during the actual visualization process, the Canvas may be much larger than the cutting outline, resulting in a smaller display area for the cutting outline and making it inconvenient for users to view the cutting outline. Alternatively, the path of the cutting outline may be too close to the edge of the Canvas, also causing inconvenience for users to view the cutting outline.

[0052] To address the aforementioned issues, this embodiment first calculates the distance between each path's annotation point and the edge of the Canvas. For example, path annotation points A, B, C, and D are the closest annotation points to the Canvas edge on the left, top, right, and bottom paths of the cutting contour, respectively. Specifically, the distance between path annotation point A and the left edge of the Canvas is 10, the distance between path annotation point B and the left edge of the Canvas is 15, and the distance between path annotation point C and the Canvas edge is... The distance from the left edge of the canvas is 13, and the distance from the D path inscription point to the left edge of the canvas is 17. Therefore, the A path inscription point is selected as the reference inscription point. Assuming the distance threshold is 8, it can be determined that the minimum distance between the A path inscription point and the left edge of the canvas is greater than the distance threshold. Therefore, the canvas needs to be enlarged so that the minimum distance between the updated reference path inscription point is equal to the distance threshold. Since the canvas is enlarged, the coordinates of each path inscription point of the cutting contour remain unchanged, which facilitates the modification of the path later.

[0053] In one specific embodiment, step S20 includes the following steps:

[0054] S40. Based on the user's selection command, select the target path in the cutting contour and generate an edit box on the Canvas, wherein the target path is located within the edit box;

[0055] S41. Based on the Canvas properties, generate zoom and displacement buttons on the edit box.

[0056] In this embodiment, since the selected target path may be small, to make it easier for the user to modify the cutting contour, after the user selects the corresponding target path, an edit box for wrapping the target path is automatically generated on the Canvas, such as... Figure 4 The dashed box shown in the image generates corresponding zoom and shift buttons on the edit box, as shown below. Figure 4 The four directional arrow images and the zoom button image shown on the dashed box allow users to zoom or pan the target path by clicking the corresponding button.

[0057] In one specific embodiment, step S20 includes the following steps:

[0058] S50. Based on the user's selection command, select the target path in the cutting contour and highlight all path marking points on the target path.

[0059] In this embodiment, to further facilitate users in modifying the selected target path, all path marking points on the target path are highlighted, for example, the selected target path is converted to an easily distinguishable color.

[0060] In one specific embodiment, step S21 includes the following steps:

[0061] S60. Receive and respond to the user's modification command for the zoom button or displacement button, so that the position coordinates of the path marking points on the target path are scaled or translated.

[0062] In this embodiment, as Figure 4 As shown, when a user places two fingers on the screen and moves them closer together or further apart, they send a modification command to the application to zoom in or out of the target path. The application responds to the modification command by zooming in or out of the target path proportionally. Similarly, when a user clicks the corresponding pan image button, they can pan the target path until the specified position is reached.

[0063] Even better, this application can operate on multiple cut files. If multiple cut files are input, such as... Figure 4 As shown, multiple selection boxes are generated at the bottom of the Canvas. Each selection box has a cutting outline that corresponds to one of the multiple cutting files. When the user selects the corresponding selection box, the corresponding cutting outline is displayed in the middle of the Canvas.

[0064] In one specific embodiment, step S22 includes the following steps:

[0065] S50. After all modification operations are performed, update the path array to obtain the target split file;

[0066] S51. Based on the plt file rules, convert the target cutting file into a plt format file and output it.

[0067] In this embodiment, all edited paths are obtained, and a PLT format file is generated according to the PLT file rules. In the PLT file, 1mm corresponds to 40 units. PD in the PLT represents tool entry, and PU represents tool retraction. The command "PD x, y" means to first enter the tool and then move to the (x, y) coordinate. The command "PU x, y" means to first retract the tool and then move to the (x, y) coordinate. It should be noted that the PLT file starts with IN and ends with "PG; @".

[0068] Finally, based on the user's instructions, the application sends the generated plt format file to the film cutting machine for contour cutting.

[0069] This invention also provides a visual modification apparatus for cutting documents, which is used to execute any embodiment of the aforementioned visual modification method for cutting documents. Specifically, please refer to... Figure 5 , Figure 5 This is a schematic block diagram of a visual modification device for cutting files provided in an embodiment of the present invention.

[0072] The drawing unit 502 is used to create a Canvas and draw the path array on the Canvas to obtain the cutting outline.

[0073] Modification unit 503 is used to modify and output the cutting contour according to preset selection rules.

[0074] This device can visualize the cutting outline on a mobile device, allowing users to easily check whether the cutting outline meets the requirements. If it does not meet the requirements, the cutting outline can be modified and output directly according to preset selection rules, making the operation simple and convenient.
