[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0047] The following is combined with Figures 1 to 2 The method for drawing the working area of ​​the present invention is described.

[0048] This invention provides a method for drawing a work area. This method can be applied to smart terminals, such as mobile phones, computers, and tablets, as well as to servers and the controllers of machinery. The following description uses the application of this method to a server as an example; however, it should be noted that this is merely illustrative and not intended to limit the scope of protection of this invention. Other descriptions in this invention are also illustrative and not intended to limit the scope of protection of this invention, and will not be described in detail thereafter.

[0049] like Figure 1 As shown, the method includes:

[0050] Step 101: Obtain the drawing parameters of the drawing tool and the operating parameters of the operating machinery.

[0051] The drawing tools include drawing brushes, and the drawing parameters include brush color, brush thickness, etc. The brush color includes the brush's RGBA value, which is the brush's RGB value (the color values ​​of the three channels: red, green, and blue) and transparency value (A).

[0052] The operational parameters include: the starting point, ending point, width of the operational path, and all operational points along the path between the starting point and the ending point of the current operation of the machinery.

[0053] Specifically, drawing parameters and operation parameters can be obtained through manual input; they can also be obtained through communication with the drawing tools and operation machinery and transmitted through them; or they can be actively obtained from the drawing tools and operation machinery by establishing a communication connection with them.

[0054] Specifically, there are various drawing software programs in the existing technology, such as management software computer-aided design (CAD), drawing software, canvas software, etc.

[0055] The invention will now be described in detail using canvas software as an example:

[0056] The canvas itself does not have drawing capabilities; drawing requires the execution of scripts. Furthermore, the canvas provides methods for directly drawing vector graphics, which can be done by specifying path points. The canvas draws vector graphics on the canvas through the execution of scripts.

[0057] Step 102: Draw the current work area based on the drawing parameters and the work parameters.

[0058] Specifically, the current work area is drawn on the canvas. Based on the pre-set mapping relationship between the canvas and the overall work area, the work parameters and drawing parameters, the current work area is drawn on the canvas to obtain the image to be processed.

[0059] The overall work area refers to all work areas in the canvas, including the current work area. The scaling ratio between the overall work area and the canvas size is preset, i.e., the mapping relationship.

[0060] In this process, the image to be processed may contain one or more regions that have already been drawn, and may also contain regions that have not been drawn. The current working area of ​​this invention is the region drawn at the current moment.

[0061] Specifically, the `globalCompositeOperation` property, a built-in feature of the canvas, sets the overlay method when multiple drawings are performed on the canvas. For example, the `lighter` option in the `globalCompositeOperation` property adds the RGBA values ​​separately to distinguish the brush color for each drawing. When the overlay value exceeds 255, 255 is used as the final value.

[0062] This invention utilizes the globalCompositeOperation property built into canvas to draw the work area, enabling the work area to be drawn quickly.

[0063] Step 103: Obtain pixel data for each pixel in the current working area.

[0064] The pixel data includes the RGBA of each pixel, namely the color value and transparency value of the red, green and blue channels.

[0065] In one specific embodiment, the acquisition of pixel data is implemented as follows: based on a preset pixel extraction method, the transparency value of each pixel is extracted; based on the extracted transparency value, the target transparency value is obtained.

[0066] Specifically, there are various pixel extraction methods. For example, extracting pixel data one by one in a horizontal-then-vertical manner; extracting pixel data one by one in a vertical-then-horizontal manner; extracting pixel data of odd-numbered rows first and then even-numbered rows in a horizontal-then-vertical manner; or randomly selecting any pixel to extract its pixel data until all pixels have been extracted.

[0067] This invention does not limit the pixel extraction method; users can set it according to their actual needs.

[0068] Below, we will use the getImageData method provided by canvas to extract pixel data.

[0069] The `getImageData` method retrieves pixel data for each pixel. It extracts pixel data one by one, first horizontally and then vertically, returning an array of pixel data. Each array has a length of 4. The RGBA values ​​of each pixel are placed in a separate array, with the total array length being the product of the number of pixels and 4. Then, based on this array of pixel data, the transparency values ​​are obtained.

[0070] In one specific embodiment, after extracting the transparency value of each pixel based on a preset pixel extraction method, the extracted transparency values ​​are stored in an array, the maximum transparency value is obtained from the array, and the maximum transparency value is determined as the target transparency value.

[0071] Specifically, since the drawing areas may overlap each time, the topmost drawing area is the newest. Therefore, the maximum transparency value is obtained from the array. This can be done by comparing all transparency values ​​in the array to find the maximum; or by comparing the currently stored transparency values ​​to find the maximum.

[0072] This invention provides an effective data basis for obtaining the target color value corresponding to the current working area by acquiring the transparency value of each pixel.

[0073] Step 104: Determine the target color value corresponding to the pixel data.

[0074] The pixel data includes the target transparency value.

[0075] In one specific embodiment, obtaining the target color value is implemented as follows: based on the target transparency value, determine the current drawing layer corresponding to the pixel data; based on the pre-created first correspondence between the drawing layer and the color value, determine the first color value corresponding to the current drawing layer; and determine the target color value based on the first color value.

[0076] Of course, you can also directly obtain the target color value corresponding to the current drawing layer based on the first correspondence.

[0077] In one specific embodiment, obtaining the current drawing layer number is achieved by: obtaining the initial transparency value and the preset transparency change value; and obtaining the current drawing layer number corresponding to the pixel data based on the initial transparency value, the transparency change value, and the target transparency value.

[0078] Specifically, a layer number calculation formula can be created in advance, and the current drawing layer number can be obtained based on the layer number calculation formula, as follows:

[0079] Input the target transparency value, transparency change value, and initial transparency value into the preset layer number calculation formula to obtain the current drawing layer number output by the layer number calculation formula.

[0080] Specifically, the initial brush color is preset, and the brush thickness corresponding to the width of the current work path is determined based on the preset matching relationship between the width of the work path and the brush thickness. Then, the current work area is drawn according to the work parameters.

[0081] For example, if the initial brush color is RGBA(0,0,0,0.01), then the corresponding initial opacity value is 0.01.

[0082] Specifically, the transparency change value of each working area is preset. Based on the superimposed transparency value, the transparency value of the current working area can be obtained, and thus the current drawing layer number can be obtained.

[0083] In this context, the number of layers and the number of layers drawn are the same concept.

[0084] Specifically, the formula for calculating the number of layers is shown in formula (1):

[0085] C=(MT-CT) / B+1 (1)

[0086] Where C is the current layer number, MT is the target transparency value, CT is the initial transparency value, and B is the transparency change value. The initial transparency value is not 0.

[0087] Specifically, a first correspondence between layer numbers and color values ​​is pre-created. At this stage, the color values ​​only include RGB values. This first correspondence is stored as a dictionary. After obtaining the current drawing layer number, the target color value corresponding to the current drawing layer is retrieved using the first correspondence. Of course, arrays, sequences, linked lists, or other storage methods can also be used.

[0088] Different layers correspond to different color values.

[0089] For example, the first correspondence is shown in Table 1:

[0090]

[0091]

[0092] Table 1 First Correspondence Relationship

[0093] In one specific embodiment, obtaining the target color value is achieved by: determining a second color value corresponding to the target transparency value based on a pre-created second correspondence between transparency values ​​and color values, and determining the target color value based on the second color value.

[0094] Of course, the target color value corresponding to the target transparency value can also be obtained directly through the second correspondence.

[0095] Different transparency values ​​correspond to different color values.

[0096] Specifically, a second mapping between transparency values ​​and color values ​​can be pre-created. In this case, the color values ​​only include RGB values. This second mapping is stored as a dictionary. After obtaining the target transparency value, the target color value corresponding to that value is retrieved using the second mapping. Alternatively, arrays, sequences, linked lists, or other storage methods can also be used.

[0097] This invention obtains the target color value of the current working area by creating a first correspondence between the number of layers and the color value and / or creating a second correspondence between the transparency value and the color value, thus providing an effective data foundation for rendering the current working area.

[0098] Step 105: Render the current working area based on the target color value.

[0099] For example, the canvas's image data rendering method (putImageData) can be used to render the current work area using the target color value and then redisplay it on the canvas.

[0100] Below, through Figure 2 The present invention will be described in detail below:

[0101] Step 201: Obtain the drawing parameters of the drawing pen and the operating parameters of the operating machinery.

[0102] Step 202: Draw the current working area in the current image based on the drawing parameters and the working parameters to obtain the image to be processed.

[0103] Step 203: Extract the pixel data of each pixel one by one using the method of first horizontal and then vertical, and store it in an array.

[0104] Step 204: Traverse the array, read and compare each transparency value, obtain the maximum transparency value, and use the maximum transparency value as the target transparency value.

[0105] Step 205: Based on the target transparency value, obtain the current drawing layer number.

[0106] Step 206: Based on the pre-created first correspondence between layer number and color value, determine the target color value corresponding to the currently drawn layer number.

[0107] Step 207: Render the current work area using the target color value and display it on the canvas.

[0108] This invention sets an initial transparency value, a transparency change value, and a first correspondence relationship. Based on the superimposed transparency value (target transparency value), a target color value is obtained, enabling different colors to be displayed for different drawing layers for visual management.

[0109] In one specific embodiment, the present invention pre-creates a thread pool; starts a sub-thread to perform the steps of obtaining the drawing parameters of the drawing tool and the operating parameters of the operating machinery; drawing the current operating area based on the drawing parameters and the operating parameters; obtaining the pixel data of each pixel in the current operating area; determining the target color value corresponding to the pixel data; and starts the main thread to perform the steps of rendering the current operating area based on the target color value.

[0110] The thread pool includes the main thread and child threads.

[0111] Alternatively, image processing can be performed by deploying sub-threads:

[0112] Existing browsers provide worker objects for running and executing scripts (JavaScript code), which communicate with the main thread via messages. A worker object is created when a web page starts, and a canvas is created within the worker object. Upon receiving job parameters, the image data is processed using a method of overlaying opacity and modifying colors. The processed data is then sent to the main thread in a queue (first-in, first-out) manner within the worker object. The main thread then handles rendering and display.

[0113] The child thread is used to execute the operations corresponding to steps 101-104.

[0114] This invention improves page rendering speed by processing image data in a sub-thread and then rendering and displaying the image in the main thread. Furthermore, it reduces the number of times the page is drawn on the visible canvas, using the main thread to completely draw the current working area on the page.

[0115] The main thread is used to execute the operation corresponding to step 105.

[0116] The method for drawing a work area provided by this invention involves acquiring the drawing parameters of the drawing tool and the work parameters of the machine; drawing the current work area based on the drawing parameters and work parameters, thus demonstrating the correspondence between the current work area and the actual work area of ​​the machine; acquiring pixel data for each pixel in the current work area; determining the target color value corresponding to the pixel data; and rendering the current work area based on the target color value. This invention determines the target color value corresponding to the current work area to effectively distinguish work areas corresponding to different drawing layers, thereby achieving effective differentiation of the work layers of the machine.
