[C++知识库]C++处理tiff图片--libtiff库（附读写图片代码）

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！！
常见函数文档

#include <vector>
#include "libtiff/tiff.h"

		return;
