根据您对字节操作部分的描述，您似乎正在将图像数据从8位正确转换为1位 . 如果是这种情况，并且您没有特定的理由使用自己的代码从头开始，则可以使用System.Drawing.Bitmap和System.Drawing.Imaging.ImageCodecInfo简化创建有效TIFF文件的任务 . 这允许您保存未压缩的1位TIFF或具有不同压缩类型的压缩文件 . 代码如下：

// first convert from byte[] to pointer

IntPtr pData = Marshal.AllocHGlobal(imgData.Length);

Marshal.Copy(imgData, 0, pData, imgData.Length);

int bytesPerLine = (imgWidth + 31) / 32 * 4; //stride must be a multiple of 4. Make sure the byte array already has enough padding for each scan line if needed

System.Drawing.Bitmap img = new Bitmap(imgWidth, imgHeight, bytesPerLine, PixelFormat.Format1bppIndexed, pData);

ImageCodecInfo TiffCodec = null;

foreach (ImageCodecInfo codec in ImageCodecInfo.GetImageEncoders())

if (codec.MimeType == "image/tiff")

{

TiffCodec = codec;

break;

}

EncoderParameters parameters = new EncoderParameters(2);

parameters.Param[0] = new EncoderParameter(Encoder.Compression, (long)EncoderValue.CompressionLZW);

parameters.Param[1] = new EncoderParameter(Encoder.ColorDepth, (long)1);

img.Save("OnebitLzw.tif", TiffCodec, parameters);

parameters.Param[0] = new EncoderParameter(Encoder.Compression, (long)EncoderValue.CompressionCCITT4);

img.Save("OnebitFaxGroup4.tif", TiffCodec, parameters);

parameters.Param[0] = new EncoderParameter(Encoder.Compression, (long)EncoderValue.CompressionNone);

img.Save("OnebitUncompressed.tif", TiffCodec, parameters);

img.Dispose();

Marshal.FreeHGlobal(pData); //important to not get memory leaks
