我试图以tiff文件格式保存图像。我已经使用Libraw来读取来自相机的原始数据,它给了我无符号的短数据。我对数据做了一些操作,我想将结果保存为Tiff文件格式的16位灰度(1通道)图像。但结果只是一张空白图片。即使我使用保留原始拜尔图像的缓冲区,它也不会正确保存。这是我用于保存的代码:将16位单通道图像写入Tiff
// Open the TIFF file
if((output_image = TIFFOpen("image.tiff", "w")) == NULL){
std::cerr << "Unable to write tif file: " << "image.tiff" << std::endl;
}
TIFFSetField(output_image, TIFFTAG_IMAGEWIDTH, width());
TIFFSetField(output_image, TIFFTAG_IMAGELENGTH, height());
TIFFSetField(output_image, TIFFTAG_SAMPLESPERPIXEL, 1);
TIFFSetField(output_image, TIFFTAG_BITSPERSAMPLE, 16);
TIFFSetField(output_image, TIFFTAG_ROWSPERSTRIP, 1);
TIFFSetField(output_image, TIFFTAG_ORIENTATION, (int)ORIENTATION_TOPLEFT);
TIFFSetField(output_image, TIFFTAG_PLANARCONFIG, PLANARCONFIG_CONTIG);
TIFFSetField(output_image, TIFFTAG_COMPRESSION, COMPRESSION_NONE);
TIFFSetField(output_image, TIFFTAG_PHOTOMETRIC, PHOTOMETRIC_MINISBLACK);
// Write the information to the file
tsize_t image_s;
if((image_s = TIFFWriteEncodedStrip(output_image, 0, &m_data_cropped[0], width()*height())) == -1)
{
std::cerr << "Unable to write tif file: " << "image.tif" << std::endl;
}
else
{
std::cout << "Image is saved! size is : " << image_s << std::endl;
}
TIFFWriteDirectory(output_image);
TIFFClose(output_image);
谢谢,问题与您提到的完全相同! – user3178756
