libtiff x64 Visual Studio 2017:链接器问题 [英] libtiff x64 visual studio 2017 : Linker Issue
问题描述
我尝试为 libtiff 使用 nuget 包:=> Package <=
I tried to use nuget package for libtiff : => Package <=
我写了一小段代码来读取多帧图像 tif 文件.
I wrote a little piece of code in order to read a multiframe image tif file.
vector<Mat> LibTiffReader::ReadMultiframeTiff(std::string FilePath)
{
vector<Mat> Result;
TIFF* tif = TIFFOpen(FilePath.c_str(), "r");
if (tif)
{
//Si le tif est ouvert, on itère sur ce qu'il y'a dedans...
do
{
Mat Image;
unsigned int width, height;
uint32* raster;
// On récupère la taille du tiff..
TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &width);
TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &height);
uint npixels = width*height; // get the total number of pixels
raster = (uint32*)_TIFFmalloc(npixels * sizeof(uint32)); // allocate temp memory (must use the tiff library malloc)
if (raster == NULL) // check the raster's memory was allocaed
{
TIFFClose(tif);
cerr << "Could not allocate memory for raster of TIFF image" << endl;
return vector<Mat>();
}
if (!TIFFReadRGBAImage(tif, width, height, raster, 0))
{
TIFFClose(tif);
cerr << "Could not read raster of TIFF image" << endl;
return vector<Mat>();
}
Image = Mat(width, height, CV_8UC3); // create a new matrix of w x h with 8 bits per channel and 3 channels (RGBA)
// itterate through all the pixels of the tif
for (uint x = 0; x < width; x++)
for (uint y = 0; y < height; y++)
{
uint32& TiffPixel = raster[y*width + x]; // read the current pixel of the TIF
Vec3b& pixel = Image.at<Vec3b>(Point(y, x)); // read the current pixel of the matrix
pixel[0] = TIFFGetB(TiffPixel); // Set the pixel values as BGR
pixel[1] = TIFFGetG(TiffPixel);
pixel[2] = TIFFGetR(TiffPixel);
}
_TIFFfree(raster);
Result.push_back(Image);
} while (TIFFReadDirectory(tif));
}
return Result;
}
我需要使用 libtiff,因为我需要用我的图像的 exif 数据做一些 OpenCV 不允许我做的事情.
I need to use libtiff, because i need to do some stuff with exif data of my image what OpenCV don't allow me to do.
问题是当我想编译时,我有链接器错误:
The problem is that when i want to compile, i have linker errors :
Error LNK2001 unresolved external symbol inflateInit_ SIA <Path> iff.lib(tif_zip.obj) 1
Error LNK2001 LNK2001 unresolved external symbol inflateInit_ SIA <Path> iff.lib(tif_pixarlog.obj) 1
我的 package.config 文件是这样的:
My package.config file is like that :
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="libtiff-msvc-x64" version="4.0.7.8808" targetFramework="native" />
</packages>
当我继续我的项目属性时,我没有看到任何包参数.我尝试将手动链接器选项添加到 .lib 文件,但我遇到了同样的问题.
When i go on my project properties, i don't see any packages parameters. I tried to add manualy linker options to .lib files, but i have the same issues.
推荐答案
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="libjpeg" version="9.0.1.4" targetFramework="native" />
<package id="libjpeg.redist" version="9.0.1.4" targetFramework="native" />
<package id="libtiff" version="4.0.6.2" targetFramework="native" />
<package id="libtiff.redist" version="4.0.6.2" targetFramework="native" />
<package id="libtiff-msvc14-x64" version="4.0.7.7799" targetFramework="native" />
<package id="zlib" version="1.2.8.8" targetFramework="native" />
<package id="zlib.v120.windesktop.msvcstl.dyn.rt-dyn" version="1.2.8.8" targetFramework="native" />
<package id="zlib.v140.windesktop.msvcstl.dyn.rt-dyn" version="1.2.8.8" targetFramework="native" />
</packages>
可能是依赖问题.我的 nuget 包配置在上面.
Maybe dependency problems. My nuget packages config is above.
