Meanwhile, in the process of drawing by using the preset point rendering function, the preset line rendering function and the preset surface rendering function respectively, if the size and format of the picture are specified, the picture may be generated according to a default value if the size and format of the picture are not specified, for example, the length and width of the picture are set to 50 respectively, specifically, the size and format of the picture may be set in a configuration file, and the generated picture may be added to the corresponding layer according to a second parameter (layer parameter) in the preset point rendering function, the preset line rendering function and the preset surface rendering function.
The drawing process of the graph in the embodiment of the invention is illustrated by taking a specific application scene as an example, but not limited to this, as shown in fig. 3, in the display map of the environmental protection project, the color of the river is drawn according to the actual water quality category, the actual water quality category changes along with time, the basic river map layer on the server cannot change the color along with the service, otherwise, the map layer cannot be popularized and applied, and the basic river map layer of the river cannot return all the flow directions of each river to be drawn by the service party, so that the basic map layer of the river is obtained from the server by combining the two data, only one color is provided on the basic map layer, the service data including the name of the river and the water quality category is obtained from the background service database, further, the matching rendering is performed by the service party according to different names of the river and water quality categories, that is how to perform the drawing specifically in different river areas, drawn in what style or presented in what color, the content may be set by the business party himself in the business code.
Furthermore, after the auxiliary layer is drawn, the different layers are overlaid to generate and output a display map, so that the display map can be seen in the page, thereby knowing that, in the embodiment of the present invention, all the contents related to the service are integrated into the service code, including the self-defined layer name in the service code, the preset map function component selects what layer is operated only according to the transmitted parameters, such as the identification information of the layer, the service data parameters, the layer parameters, and the like, the code related to the service is not specifically defined in the preset map function component, assuming that the layer name needs to be modified, only the layer name needs to be modified in the service code, and it is not necessary to consider whether the drawing of the map is affected, for example, the layer name is defined as the aloyer at the beginning, and the name of the map that cannot be seen when the method is called is mapup. Ready to change to river layer, then the MapSupport. renderRiver (data) can be done by only modifying the second parameter in the method call. Meanwhile, once the information on the server map layer is modified, the emphasis is only required to be placed in the mapUport.js, and because all the methods used in the service codes are called in the mapUport.js, the functions of the map are not touched, so that the separation of the map functional component and the service codes is completely realized, the map functional component or the service codes can be maintained at the later stage conveniently, and the reusability of the map functional component is improved.
