So if you want to do streaming you should have a TIFF_2_TIFF-F normalizer in the front of the pipeline and every filter in the pipeline should write according to TIFF-F. But as stated in the RFC the filters should be able to read non TIFF-F conforming TIFF format to be more generic.

And to place IFD in front of image data it should be enough to call TIFFCheckpointDirectory() after setting all tags. Something like:

    out = TIFFOpen("out.tif", "w");
    TIFFSetField(out, TIFFTAG_IMAGEWIDTH, image_width);
    TIFFSetField(out, TIFFTAG_PHOTOMETRIC, photo);
    TIFFSetField(out, TIFFTAG_ROWSPERSTRIP, TIFFDefaultStripSize(out, 0));


    for (i = 0; i < image_height; i++)
        TIFFWriteScanline(out, buf + i * image_width * spp, i, 0);


Just a suggestion fro those, who want to create TIFFs, suitable for sequental access.
