我試圖以tiff文件格式保存圖像。我已經使用Libraw來讀取來自相機的原始數據,它給了我無符號的短數據。我對數據做了一些操作,我想將結果保存爲Tiff文件格式的16位灰度(1通道)圖像。但結果只是一張空白圖片。即使我使用保留原始拜爾圖像的緩衝區,它也不會正確保存。這是我用於保存的代碼:將16位單通道圖像寫入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);
謝謝,問題與您提到的完全相同! – user3178756
