ArcGIS二次开发编程实例。全书分两部分：基础篇和提高篇。基础篇通过 100多个具体的实例详细地讲解了ArcGIS 二次开发过程中涉及到的各个主要的知识点；提高篇则以实际项目开发为例，综合运用基础篇的各个知识点，详细地展示ArcGIS 二次开发的流程、方法和各种开发技巧。-ArcGIS programming examples of secondary development. The whole book in two parts: the basis of papers and articles improve. The basis of more than 100 articles, through specific examples to explain in detail the process of secondary development of the ArcGIS involved in each of the major points of knowledge improve articles while the actual project development as an example, the integrated use of knowledge based on various papers, the detailed display ArcGIS secondary flow development, methods and development techniques.

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
