TIF图片格式本是网上有许多资料介绍。
这两天找了一些资料，用做切割TIF图片用的。

功能：把多页的TIF图片切割为单页的TIF多文件!

下面是C#代码(已封装)：

1 using System;
2 using System.IO;
3 using System.Drawing;
4 using System.Collections;
5 using System.Drawing.Imaging;
6
7 namespace SampleProject.Components {
8     class ImageSplit {
9         private FileInfo _imageFile;
10         private ArrayList _imagesName = new ArrayList();
11
12         public ArrayList ImagesName {
13             get { return _imagesName; }
14         }
15
16         public ImageSplit( FileInfo imageFile, string IncisionDir ) {
17             this._imageFile = imageFile;
18             Split( IncisionDir );
19         }
20
21         ///
22         /// Split image to folder
23         ///
24         ///
25         protected void Split( string IncisionDir ) {
26             try {
27                 Image img = Image.FromFile( _imageFile.FullName );
28                 Guid guid = (Guid)img.FrameDimensionsList.GetValue( 0 );
29                 FrameDimension dimension = new FrameDimension( guid );
30                 int totalPage = img.GetFrameCount( dimension );
31
32                 for ( int i = 0;i < totalPage;i++ ) {
33                     img.SelectActiveFrame( dimension, i );
34                     img.Save( IncisionDir + "//" + _imageFile.Name.Substring( 0, _imageFile.Name.LastIndexOf( '.' ) ) + "_" + i + ".tif", System.Drawing.Imaging.ImageFormat.Tiff );
35                     _imagesName.Add( _imageFile.Name.Substring( 0, _imageFile.Name.LastIndexOf( '.' ) ) + "_" + i + ".tif" );
36                 }
37
38                 img.Dispose();
39             }
40             catch {
41                 return;
42             }
43         }
44
45         ///
46         /// Move image to backup folder
47         ///
48         ///
49         public void MoveImage( string backupDir ) {
50
51             string strDir = backupDir + "//" + DateTime.Now.ToShortDateString();
52
53             if ( !Directory.Exists( strDir ) ) {
54                 Directory.CreateDirectory( strDir );
55             }
56
57             if ( File.Exists( strDir + "//" + _imageFile.Name ) ) {
58                 File.Delete( strDir + "//" + _imageFile.Name );
59             }
60
61             _imageFile.MoveTo( strDir + "//" + _imageFile.Name );
62         }
63     }
64 }

调用方法：

1 System.IO.DirectoryInfo sourceFolder = new DirectoryInfo( IMAGE_SOURCE_FOLDER );
2 FileInfo[] imageFile = sourceFolder.GetFiles();
3
4 for ( int i = 0;i < imageFile.Length;i++ ) {
5     Components.ImageSplit split = new Components.ImageSplit( imageFile[i], INCISION_FOLDER );
6     split.MoveImage( IMAGE_MOVETO_FOLDER );
7 }
