Now I want to take the generated PDF and resave it as a compressed
PDF. (like automator can do)
How can I do that?
I looked into PDFKit and read about CGPdfContext but didnt find
anything.
If this is Leopard, it is pretty straightforward. You need to create a
QuatzFilter that does the compression (look in Quartz.framework/
Frameworks/QuartzFilters/ for the headers).
You can pass this QuartzFilter in a dictionary to -[PDFDocument
writeFile/URL: withOptions:] (a class in PDF Kit). I think the header
file for PDFDocument on Leopard has some comments to this effect. Here:
// Methods to record the current state of the PDFDocument as data or a
file. Passing a QuartzFilter object in the
// options dictionary with the key @"QuartzFilter" will allow you to
have the filter applied when saving the PDF.
- (NSData *) dataRepresentation;
- (BOOL) writeToFile: (NSString *) path;
- (BOOL) writeToFile: (NSString *) path withOptions: (NSDictionary *)
options;
- (BOOL) writeToURL: (NSURL *) url;
- (BOOL) writeToURL: (NSURL *) url withOptions: (NSDictionary *)
options;
