Method Documentation

◆ convertPDFFile:saved_pdf_path:convert_to_version:progress_callback:()

- (FSResultInformation *) convertPDFFile: (NSString *)  src_pdf_path
saved_pdf_path: (NSString *)  saved_pdf_path
convert_to_version: (int)  convert_to_version
progress_callback: (id<FSComplianceProgressCallback>)  progress_callback 

Convert a PDF file to a specified PDF version.

Parameters
[in]src_pdf_pathA complete path of source PDF file to be converted. This should not be an empty string.
[in]saved_pdf_pathA complete path for saving the converted PDF file. This should not be an empty string.
[in]convert_to_versionAn integer that specifies the PDF version to convert to, for example value 14 means version "1.4", value 15 means "1.5", and etc. Currently, only support version values 13, 14, 15, 16, and 17. Specially, when version value is 13 (which means PDF 1.3):
  • if source PDF file contains transparency data, it will be converted to PDF 1.4 instead of PDF 1.3 (not support transparency). And user can check hit data in the returned FSResultInformation object for more details.
  • if source PDF file does not contain any transparency data, it will be converted to PDF 1.3 as expected.
