Hello,
executing the following code adds an additional frame to the result. Looks like the addition is a preview, I don't know for sure, though. The second frame may or may not have a different size and/or colorspace.
This works with all tiff images I tested.

Code:

using (var reader = ImageReader.Create(TiffResource))
using (var writer = new TiffWriter(result))
{
    Console.Out.WriteLine("Starting with {0} Frames.", reader.Frames.Count); // 1 Frame

    var settings = new TiffSettings(CompressionType.Lzw)
                        {
                            Exif = reader.Exif // this is the culprit
                        };
    writer.Setup(settings);

    (reader + writer).Run();
}

using (var resultReader = ImageReader.Create(result))
{
    Console.Out.WriteLine("Now there are {0} Frames.", resultReader.Frames.Count); // 2 Frames
}


Is this intended behaviour? Is there a builtin way to prevent this or do I have to scan the exif for bitmaps and remove them?

Regards,
Sebastian

Hi Sebastian,

Unfortunately, we could not reproduce the problem with our TIFF files.
Could you post here your one?

Hi Sebastian,

Sorry for the long delay.
Thank you for your image.

We have fixed the issue. From the next release, Exif thumbnails will not be included in a reader's frame collection.
Best regards,
Eugene Kosmin.

The fix is available with just published GM 9.1.33. Please check the NuGet repository.
