Problems solved by technology

The problem is: (1) In large-scale software, contour analysis is only a small part of its huge functions. For meteorological service products that only need to make contour analysis as the core, it is bulky, complicated to operate, Poor controllability and scalability, it is difficult to meet the flexible and diverse product requirements of meteorological services
It becomes very difficult to deal with large-scale graphic analysis, especially to automatically generate pictures in the required format without human intervention to support real-time updated dynamic services (such as websites, etc.), and it is even more difficult to embed them as a graphic processing sub-module in in other systems

Embodiment Construction

[0010] The method for automatically generating contour image files adopts the following steps: (1) using VC++6.0 as a program development platform to establish a project file of an MFC application program. (2) Establish the contour analysis class, take the station and auxiliary points as the grid points, use the triangular grid to conduct contour analysis, and establish an OnDraw() function to call the functions associated with various display signs. (3) Save the information related to the automatic analysis of graphics (such as: analysis level information, color filling information, grid information, grid point information, professional line information, background picture, etc.) in the corresponding file. (4) Information related to the image output format (such as: whether to display the site, whether to superimpose professional lines, whether to display the title, whether to display the color spot map or contour map, whether to display the background color, whether to displa...

Abstract

The invention discloses a method to automatic generate isoline picture file, which comprising the following steps: (1) constructing triangle grid; (2) keeping the relative information with the isoline automatic analyzing in the relative file; (3) using the relative information with the picture output form as display signal; storing in the picture output form file; (4) embodying the all controlled information in a controlling file; using as command line parameter; transmitting to program; (5) constructing a analyzing case of the isoline; (6) constructing structure array with the picture output form; loading the relative display signal in the picture output form file; (7) sending order information of the automatic generate picture file; (8) sending the information; pulling out program. This method can be used as submodule to embed into other system.

Description

(1) Technical field [0001] The invention relates to a method for automatically generating contour picture files, which automatically performs contour analysis and automatically generates picture files in a predetermined format. It belongs to the field of computer graphics analysis. (2) Background technology [0002] With the development of the economy and the advancement of science and technology, the original meteorological products mainly based on text tables are far from keeping up with the pace of the times. Graphic products are more and more popular with people for their image and intuitive advantages. The development of graphic products , Improving service quality and improving service capabilities have become urgent problems to be solved. There are many softwares that can perform isoline analysis and output graphics, such as sufer in the United States, micaps in the China Meteorological Administration, and various geographic information systems. Many provincial meteo...
