merge images

[Zeeway]

hi,everyone
I have a question about merging images. I want to merge serval tiff
images into one file using C#,that means the final file has multiple
frames.My problem is that I want each frame in the final file is of
single-strip,but when I want to merge serval images which has been of
singe-strip,the final file my codes produced contains images which are all
of multiple-strips. My codes is listed below:

public static bool MergeTifs(ref string mergedFile,Arra yList
fileList)
{
int counts = fileList.Count;
if (counts < 1)
{
return false;
}
try
{
EncoderParamete rs eps=new EncoderParamete rs(2);

eps.Param[0] = new

EncoderParamete r(Encoder.SaveF lag,(long)Encod erValue.MultiFr ame);
eps.Param[1] = new EncoderParamete r(Encoder.Compr ession,
(long)EncoderVa lue.Compression CCITT3);

System.Drawing. Image mergedImage =
System.Drawing. Image.FromFile( (string)fileLis t[0]);

//Get the correct encoder from the list of available
encoders

ImageCodecInfo[] infos = ImageCodecInfo. GetImageEncoder s();

int n=0;
while(infos[n].MimeType!="ima ge/tiff")
n++;

//save the first page
System.Drawing. Image imageToAdd = null;
mergedImage.Sav e(mergedFile,in fos[n],eps);
Bitmap firstBmp = new Bitmap((string) fileList[0]);
int first_num = firstBmp.GetFra meCount(FrameDi mension.Page);
for(int j = 1; j < first_num; j++)
{
firstBmp.Select ActiveFrame(Fra meDimension.Pag e,j);
eps.Param[0]=new
EncoderParamete r(Encoder.SaveF lag,(long)Encod erValue.FrameDi mensionPage);
mergedImage.Sav eAdd(firstBmp,e ps);
}
firstBmp.Dispos e();
for(int i = 1; i< counts; i++)
{
string fileToAdd = (string)fileLis t[i];
imageToAdd = System.Drawing. Image.FromFile( fileToAdd);
int num =
imageToAdd.GetF rameCount(Frame Dimension.Page) ;
for(int k = 0; k < num; k++)
{

imageToAdd.Sele ctActiveFrame(F rameDimension.P age,k);
eps.Param[0]=new
EncoderParamete r(Encoder.SaveF lag,(long)Encod erValue.FrameDi mensionPage);
mergedImage.Sav eAdd(imageToAdd ,eps);
}
imageToAdd.Disp ose();
}
eps.Param[0]=new

EncoderParamete r(Encoder.SaveF lag,(long)Encod erValue.Flush);
mergedImage.Sav eAdd(eps);
mergedImage.Dis pose();
return true;
}
catch
{
return false;
}
}

the first parameter is the file name of the final file.
Could anyone kindly help me? Thank you in advance.
