1、下载并安装Spire.Doc,并将Spire.Doc.dll文件引用到项目中。
2、 将代码放入Visual Studio中：
using Spire.Doc;
using Spire.Doc.Documents;
using System;
using System.Drawing;
using System.Drawing.Imaging;
namespace Word_to_Tiff2
{
class Program
{
static void Main(string[] args)
{
Document document = new Document("Sample.docx");
JoinTiffImages(SaveAsImage(document), "result.tiff", EncoderValue.CompressionLZW);
}
private static Image[] SaveAsImage(Document document)
{
Image[] images = document.SaveToImages(ImageType.Bitmap);
return images;
}
private static ImageCodecInfo GetEncoderInfo(string mimeType)
{
ImageCodecInfo[] encoders = ImageCodecInfo.GetImageEncoders();
for (int j = 0; j < encoders.Length; j++)
{
if (encoders[j].MimeType == mimeType)
return encoders[j];
}
throw new Exception(mimeType + " mime type not found in ImageCodecInfo");
}
public static void JoinTiffImages(Image[] images, string outFile, EncoderValue compressEncoder)
{
//use the save encoder
System.Drawing.Imaging.Encoder enc = System.Drawing.Imaging.Encoder.SaveFlag;
EncoderParameters ep = new EncoderParameters(2);
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.MultiFrame);
ep.Param[1] = new EncoderParameter(System.Drawing.Imaging.Encoder.Compression, (long)compressEncoder);
Image pages = images[0];
int frame = 0;
ImageCodecInfo info = GetEncoderInfo("image/tiff");
foreach (Image img in images)
{
if (frame == 0)
{
pages = img;
//save the first frame
pages.Save(outFile, info, ep);
}
else
{
//save the intermediate frames
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.FrameDimensionPage);
pages.SaveAdd(img, ep);
}
if (frame == images.Length - 1)
{
//flush and close.
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.Flush);
pages.SaveAdd(ep);
}
frame++;
}
}
}
}
3、运行代码后，生成result.tiff文档，在项目Bin文件夹下面手动选择用图片方式打开后，文档如下图所示：
