如何将位图数组转换为TIFF格式的全新图像，在这个新的tiff图像中添加所有位图作为帧？
使用.NET 2.0。
答案 0 :(得分：78)
从第一个位图开始，将其放入Image对象
Bitmap bitmap = (Bitmap)Image.FromFile(file);
将位图以tiff
的形式保存到内存中MemoryStream byteStream = new MemoryStream();
bitmap.Save(byteStream, ImageFormat.Tiff);
将Tiff放入另一个Image对象
Image tiff = Image.FromStream(byteStream)
准备编码器：
var encoderInfo = ImageCodecInfo.GetImageEncoders().First(i => i.MimeType == "image/tiff");
EncoderParameters encoderParams = new EncoderParameters(2);
encoderParams.Param[0] = new EncoderParameter(Encoder.Compression, (long)EncoderValue.CompressionNone);
encoderParams.Param[1] = new EncoderParameter(Encoder.SaveFlag, (long)EncoderValue.MultiFrame);
保存到文件：
tiff.Save(sOutFilePath, encoderInfo, encoderParams);
对于后续页面，请准备编码器：
EncoderParameters EncoderParams = new EncoderParameters(2);
EncoderParameter SaveEncodeParam = new EncoderParameter(
Encoder.SaveFlag,
(long)EncoderValue.FrameDimensionPage);
EncoderParameter CompressionEncodeParam = new EncoderParameter(
Encoder.Compression, (long)EncoderValue.CompressionNone);
EncoderParams.Param[0] = CompressionEncodeParam;
EncoderParams.Param[1] = SaveEncodeParam;
tiff.SaveAdd(/* next image as tiff - do the same as above with memory */, EncoderParams);
最后刷新文件：
EncoderParameter SaveEncodeParam = new EncoderParameter(
Encoder.SaveFlag, (long)EncoderValue.Flush);
EncoderParams = new EncoderParameters(1);
EncoderParams.Param[0] = SaveEncodeParam;
tiff.SaveAdd(EncoderParams);
这应该让你开始。

在Google上搜索了一下后发现了这篇文章。我尝试了'b'c'd'e'f'g'h'在帖子中的代码，但这对我不起作用。也许，我没有做正确的事情。
无论如何，我发现另一篇文章将图像保存到多页tiff。以下是帖子的链接：http://www.bobpowell.net/addframes.htm
此外，这里的代码对我有用。它应与该帖子相同。
Encoder encoder = Encoder.SaveFlag;
ImageCodecInfo encoderInfo = ImageCodecInfo.GetImageEncoders().First(i => i.MimeType == "image/tiff");
EncoderParameters encoderParameters = new EncoderParameters(1);
encoderParameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.MultiFrame);
// Save the first frame of the multi page tiff
Bitmap firstImage = (Bitmap) _scannedPages[0].RawContent;
firstImage.Save(fileName, encoderInfo, encoderParameters);
encoderParameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.FrameDimensionPage);
// Add the remaining images to the tiff
for (int i = 1; i < _scannedPages.Count; i++)
{
Bitmap img = (Bitmap) _scannedPages[i].RawContent;
firstImage.SaveAdd(img, encoderParameters);
}
// Close out the file
encoderParameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.Flush);
firstImage.SaveAdd(encoderParameters);

有用的话题。谢谢（你的）信息。我需要从base64编码的字符串数组中缝合多页图像。这是我根据此主题中的信息放在一起的内容。我不太清楚为什么我必须创建一个显式指定的图像格式的内存流，但这是最终工作，如果有更好的方法来处理这个请告诉我。感谢

private void SaevAsMultiPageTiff(string sOutFile, string[] pagesbase64Array)
{
System.Drawing.Imaging.Encoder encoder = System.Drawing.Imaging.Encoder.SaveFlag;
ImageCodecInfo encoderInfo = ImageCodecInfo.GetImageEncoders().First(i => i.MimeType == "image/tiff");
EncoderParameters encoderParameters = new EncoderParameters(1);
encoderParameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.MultiFrame);
Bitmap firstImage = null;
try
{
using (MemoryStream ms1 = new MemoryStream())
{
using (MemoryStream ms = new MemoryStream(Convert.FromBase64String(pagesbase64Array[0])))
{
Image.FromStream(ms).Save(ms1, ImageFormat.Tiff);
firstImage = (Bitmap)Image.FromStream(ms1);
}
// Save the first frame of the multi page tiff
firstImage.Save(sOutFile, encoderInfo, encoderParameters); //throws Generic GDI+ error if the memory streams are not open when this is called
}
encoderParameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.FrameDimensionPage);
Bitmap imagePage;
// Add the remining images to the tiff
for (int i = 1; i < pagesbase64Array.Length; i++)
{
using (MemoryStream ms1 = new MemoryStream())
{
using (MemoryStream ms = new MemoryStream(Convert.FromBase64String(pagesbase64Array[i])))
{
Image.FromStream(ms).Save(ms1, ImageFormat.Tiff);
imagePage = (Bitmap)Image.FromStream(ms1);
}
firstImage.SaveAdd(imagePage, encoderParameters); //throws Generic GDI+ error if the memory streams are not open when this is called
}
}
}
catch (Exception)
{
//ensure the errors are not missed while allowing for flush in finally block so files dont get locked up.
throw;
}
finally
{
// Close out the file
encoderParameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.Flush);
firstImage.SaveAdd(encoderParameters);
}
}

在处理和创建标准化格式的文件方面，我不赞成微软的跟踪记录，我建议使用ImageMagick，以MagickNet的形式提供.Net库（请注意，{{3目前有一个间谍软件弹出窗口，我已经提醒网站所有者）。

这是multi-tiff文件的拆分操作。它就像字符串子串函数一样工作。第一个图像索引将是您的MasterBitMap，您将继续向MasterBitmap添加框架，直到索引结束。
public void SaveMultiFrameTiff(int start, int end)
{
string outputFileName = "out.TIF";
string inputFileName = "input.TIF";
try
{
Bitmap MasterBitmap = new Bitmap(inputFileName ); //Start page of document(master)
Image imageAdd = Image.FromFile(inputFileName ); //Frame Image that will be added to the master
Guid guid = imageAdd.FrameDimensionsList[0]; //GUID
FrameDimension dimension = new FrameDimension(guid);
// start index cannot be less than 0 and cannot be greater than frame count
if (start < 1 || end > MasterBitmap.GetFrameCount(dimension)) { return; }
EncoderParameters ep = new EncoderParameters(1);
//Get Image Codec Information
ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();
ImageCodecInfo codecInfo = codecs[3]; //image/tiff
//MultiFrame Encoding format
EncoderParameter epMultiFrame = new EncoderParameter(System.Drawing.Imaging.Encoder.SaveFlag, (long)EncoderValue.MultiFrame);
ep.Param[0] = epMultiFrame;
MasterBitmap.SelectActiveFrame(dimension, start - 1);
MasterBitmap.Save(outputFileName, codecInfo, ep);//create master document
//FrameDimensionPage Encoding format
EncoderParameter epFrameDimensionPage = new EncoderParameter(System.Drawing.Imaging.Encoder.SaveFlag, (long)EncoderValue.FrameDimensionPage);
ep.Param[0] = epFrameDimensionPage;
for (int i = start; i < end; i++)
{
imageAdd.SelectActiveFrame(dimension, i);//select next frame
MasterBitmap.SaveAdd(new Bitmap(imageAdd), ep);//add it to the master
}
//Flush Encoding format
EncoderParameter epFlush = new EncoderParameter(System.Drawing.Imaging.Encoder.SaveFlag, (long)EncoderValue.Flush);
ep.Param[0] = epFlush;
MasterBitmap.SaveAdd(ep); //flush the file
}
catch (Exception ex)
{
throw ex;
}
}
}
