How to set field Orientation in tiff about libtiff.net HOT 9 CLOSED

        using (Tiff input = Tiff.Open(@"D:\1.tif", "a"))
        {
            input.SetDirectory(0);
           input.SetField(TiffTag.ORIENTATION, BitMiracle.LibTiff.Classic.Orientation.BOTLEFT);
            input.RewriteDirectory();
         }

Work!!!

but I need use
using (Tiff input = Tiff.ClientOpen("in-memory", "a", stream, new TiffStream()))

it does not work

from libtiff.net.

Please clarify what does "no working !!!" means.

from libtiff.net.

var stream = new MemoryStream(File.ReadAllBytes(@"D:\1.tif"));
using (Tiff input = Tiff.ClientOpen("in-memory", "a", stream, new TiffStream()))
{
input.SetDirectory(0);
var result=input.SetField(TiffTag.ORIENTATION, BitMiracle.LibTiff.Classic.Orientation.RIGHTBOT);
input.RewriteDirectory();
}

In this case the field ORIENTATION no save correctly
Open the tiff with irfanView, the image no show rotated

But use

using (Tiff input = Tiff.Open(@"D:\1.tif", "a"))
{
input.SetDirectory(0);
input.SetField(TiffTag.ORIENTATION, BitMiracle.LibTiff.Classic.Orientation.BOTLEFT);
input.RewriteDirectory();
}
works correctly !!!

I need to use the variant Tiff input = Tiff.ClientOpen("in-memory", "a", stream, new TiffStream())
because I have the memory tiff

from libtiff.net.

Please note that you use different values for TiffTag.ORIENTATION in the first and the second cases.

Please also note that the first code block affects memory stream only and you should save the memory stream into a file.

from libtiff.net.

Please also note that you create non-expandable memory stream.
