CompactFile(string,string,int) Method

Summary

Compacts TIFF/BigTIFF files with default options.

Syntax

Objective-C

C++

public void CompactFile( 
   string srcFileName, 
   string destFileName, 
   int pages 
)

Public Overloads Sub CompactFile( _ 
   ByVal srcFileName As String, _ 
   ByVal destFileName As String, _ 
   ByVal pages As Integer _ 
)

- (BOOL)compactFile:(NSString *)sourceFile  
    destinationFile:(NSString *)destinationFile  
              pages:(NSUInteger)pages  
              error:(NSError **)error

public: 
void CompactFile(  
   String^ srcFileName, 
   String^ destFileName, 
   int pages 
)

Parameters

srcFileName
A String containing the name of the file being compacted. All the pages will be read from this file.

destFileName
A String containing the name of the file in which all the pages will be written.

pages
Value that represents the number of pages to copy. Use 0 to copy all the pages. If pages is > 0, only pages will be copied to destFileName.

Remarks

This method can also be used to copy or extract one or more pages from a TIFF/BigTIFF file and copy them without recompression to another TIFF/BigTIFF file.

This method can also be used to convert a TIFF file to BigTIFF or vice versa. The destination file will be Tiff or BigTiff depending on BigTiff.
