CompactFile(string,string,int) Method (original) (raw)
Summary
Compacts TIFF/BigTIFF, PNG or Exif JPEG files with default options.
Syntax
C#
Objective-C
C++/CLI
Python
- (BOOL)compactFile:(NSString *)sourceFile
destinationFile:(NSString *)destinationFile
pages:(NSUInteger)_pages_
error:(NSError **)error
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 .
