环境
VS2017
libtiff 4.0.9
配置
上官网下载合适的版本后
打开控制台 切换当前目录到tiff-x.x.x,找到vs2017的vcvars64.bat脚本
控制台中执行 vcvars64.bat
然后 执行 nmake /f makefile.vc
本人操作如下
d:\tiff-4.0.9> D:\VS2017\VC\Auxiliary\Build\vcvars64.bat
d:\tiff-4.0.9> nmake /f makefile.vc
编译好的tifflib.dll tifflib.lib 以及头文件都在libtiff 目录中
链接器-输入加入:libtiff.lib
读写图片代码
各函数参数和用法强烈建议google!!
