将多个 TIFF 文件合并为一个 TIFF 文件 [英] Merging multiple TIFF files in one TIFF file

问题描述

我一直在尝试使用发布在以下位置的 TiffUtil 类的 mergeTiffStreams 方法:

I've been trying to use the mergeTiffStreams method of the TiffUtil class posted at:

http://kseesharp.blogspot.com/2007/12/class-for-tiff-manipulation.html

然而，就像其他人对该线程的评论一样，最终结果是我收到一个只包含我的第一个 TIFF 文件的流.我在 MemoryStream 数组中传递的其他 TIFF 不包括在内.

However, like other people have commented on that thread, the end result is that I receive a Stream that only contains my first TIFF file. The other TIFFs that I passed in the MemoryStream array are not included.

有没有其他人遇到过这个问题?如果是这样，任何建议将不胜感激.

Has anyone else run into this problem before? If so, any advice would be most appreciated.

谢谢.

[更新]

这是我目前拥有的代码.它返回的流只包含传入数组中的第一个 TIFF.

Here's the code I have at the moment. The stream that it returns only contains the first TIFF from the array passed in.

    public MemoryStream mergeTiffStreams(MemoryStream[] tiffStreams)
    {
        if (tiffStreams == null)
            throw new ArgumentNullException("tiffStreams");

        Encoder enc = Encoder.SaveFlag;

        ImageCodecInfo info = null;
        foreach (ImageCodecInfo ice in ImageCodecInfo.GetImageEncoders())
            if (ice.MimeType == "image/tiff")
                info = ice;

        EncoderParameters ep = new EncoderParameters(1);
        ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.MultiFrame);
        MemoryStream tiffStream = new MemoryStream();
        Bitmap masterBitmap = new Bitmap(tiffStreams[0]);
        masterBitmap.Save(tiffStream, info, ep);

        ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.FrameDimensionPage);
        for (int x = 1; x < tiffStreams.Length; x++)
        {
            masterBitmap.SaveAdd(Image.FromStream(tiffStreams[x]), ep);
        }

        ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.Flush);
        masterBitmap.SaveAdd(ep);

        return tiffStream;
    }

推荐答案

您的问题可能在于您如何处理返回的流.例如，如果您想将其保存到 IO 使用:

Your problem might be in how you're handling the stream returned. If, for example, you want to save it to IO use:

File.WriteAllBytes(myPath, tiffStream.ToArray());

而不是从流中创建一个新的 Bitmap 对象.反正那是我的问题.

rather than creating a new Bitmap object from the stream. That was my problem anyway.
