CxImage的编译及简单使用举例

1、  从http://sourceforge.net/projects/cximage/下载最新的CxImage 702源码；

2、  解压缩后，以管理员身份打开CxImageFull_vc10.sln工程，在编译之前先将每个工程属性的Character Set由原先的Use Unicode Character Set改为Use Multi-ByteCharacter Set，首先编译jasper、jbig、jpeg、libdcr、libpsd、mng、png、tiff、zlib这9个库，然后编译cximage，cximagecrtdll，在接着编译cximagemfcdll，在编译cximagemfcdll之前，先修改其属性，linker->input->Additional Dependencies,将$(OutDir)png.lib等改为../../Debug/png.lib(../../Release/png.lib)，最后编译demo、demodll；全部编译完后即可生成相应的静态库和动态库；

3、  目前CxImage支持的图像格式包括：bmp、gif、jpg、png、ico、tif、tga、pcx、wbmp、wmf、jp2、jpc、pgx、pnm、ras、jbg、mng、ska、raw和psd；

4、  CxImage中所包含的图像操作可通过打开index.htm来查看；        

5、新建一个控制台工程testCxImage，将Character Set设为Use Multi-Byte Character Set，各个文件的内容为：

stdafx.h:
