转Word文档为Tiff格式

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;usi艘绒庳焰ng 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：
