shp演示程序
主要改正了使用点线符号(PointLineSymbol)绘制时的死机问题,并调整了几处不正确的bitmap用法。此外增加了小工具shp2esd,用来批量转换shapefile为esd文件。
把这几个目录覆盖掉1.0版的同名目录(先下载easymap1.0),重新编译就可以使用了。
-shp demo program to correct the use of the main points and lines symbols (PointLineSymbol) drawn at the time of death, and adjust the number of incorrect usage bitmap. In addition an increase of small tools shp2esd, used for bulk document conversion shapefile for esd. Several out this directory cover version 1.0 of the same name directory (first download easymap1.0), the compiler can re-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
