采用下拉菜单的方式实现数字插值方式的选择，并通过回调函数完成相应的插值算法和图像显示，在原始数据的输入和处理上，主要采用字符串的写入和读取与处理方式，实现对原始数据读入和分析。本次设计是对单选按钮的使用、按钮控件的应用及轴显示图形应用的综合设计，最终实现了多种插值算法的切换。通过设计与调试，本工具包集成了一维插值和二维插值中的最邻近插值，最小立方插值，线性插值等插值算法，最后达到对同一组数据可以用不同插值方法设计，通过优化处理得到适合插值算法。(The drop-down menu select digital interpolation method, and the callback function completed corresponding interpolation algorithm and image display, in the original data input and processing, mainly uses the string write and read and treatment, to read and analyze the original data. This design is on the radio button, button control application and axis shows the comprehensive design of graphics applications, finally realizes the switching of various interpolation algorithms. Through the design and debugging, the kit integrates the one-dimensional and two-dimensional interpolation method of the nearest interpolation, the smallest cubic interpolation, linear interpolation, such as interpolation algorithm, and finally achieve the same set of data can be designed using different interpolation methods. By optimizing the processing for the interpolation algorithm.)
