Hi list,
i've seen this discussion before around 2006 but found no relevant answer, here goes:
We have a Foundation tool which adds annotations to a pdf and saves the pdf to disk again.
We use the PDFKit classes for that.
Now, when processing a pdf that has pdf-version 1.5 (Created from InDesign), after saving our pdf, it becomes version 1.4, we also noticed the same behavior with Preview.app, saving this same pdf also reduces the version to 1.4.
Question is, can we "force" the version to stay the same or is this a restriction in Quartz?
Below is a code snippet.
Thanks in advance,
Florian.
NSData *pdfData = [NSData dataWithContentsOfFile:pathToPDF];
PDFDocument *pdfDoc = [[PDFDocument alloc] initWithData:pdfData];
AddAnnotationsToPDF(pdfDoc, parsedAnnotations(xmlDoc));
// Saving the pdf
if(![pdfDoc writeToFile:pathToPDF])
{
NSLog(@"Could not save pdf file");
return -1;
}
