map scale mapping of source code, demonstration of a wide range of map scale

MapInfo MapX是一个用来做地图化工作的OCX控件，它可以很容易地在您的应用程序中加入强大的制图功能。它可以把您的数据用地图的形式显示出来，更易于理解。地图形式可以比简单的图表、图形提供更多的信息，而且描述地图比描述数据表更加简单迅速。本章主要对mapx的安装和在编程语言中的使用进行讲解。-MapInfo MapX is used as a map of the OCX controls, it can very easily in your application into a powerful mapping function. It could use your data in the form of maps, and easier to understand. Maps can be more than a simple form of charts, graphics provide more information, and the descriptions over the map data sheet describes more simply and rapidly. This chapter primarily MapX in the installation and programming language on the use.

本文结合DCT变换的特性，利用分形的Peano一hilbert扫描曲线，对基于DCT变换的图像编码方法进行了研究，并提出了改进方法。主要工作分为两个部分: 一是在分块DCT基础上的改进。对分块后生成的各图像块矩阵，不直接作二维DCT变换，而是先进行扫描，使之重排成一维向量，再进行一维DCT变换，这样可以减少运算量。 其次是对层次余弦变换编码部分的改进。使用层次DCT变换与零树编码相结合的方法，并在扫描编码过程中，按Peano一hilbert扫描顺序进行编码。这样不仅可以减少“块效应”，而且可以加快编码速度。-this paper the characteristics of DCT, using fractal Peano a Hilbert scanning curve, the DCT-based image coding method for the study and improvement of methods. The work is divided into two main parts : First, the DCT block on the basis of improvements. Right after block production of the image block matrix, not for direct two-dimensional DCT, but first scan, so they line up in a heavy-dimensional vector and then a peacekeeping DCT, thus reducing the amount of computation. Secondly, the level of cosine transform coding some of the improvements. The use level of DCT and zero tree coding combination of methods, coding and scanning process, according to a Hilbert Peano code scanning sequence. This will not only reduce the "blocking
