If I understand correctly your point, it seems that in the first
case, you
use the direct to data print operation and in the second case, you
use the
direct to file print operation then read back the file in memory
and send it
to Quick Look. Both methods use
QLPreviewRequestSetDataRepresentation(). Am
I right?
What do you mean when you say "does not display the content as
multipage".
What does it display?
You should try to dump on disk the data produced in the first case
and take
a look at it.

Hi all,
I am trying to generate multipage pdf data for display in a quick
look
preview from rich text attributed string data. Attributed strings
don't know
anything about pages, so it seems to me that I'll have to go
through the OS
printing architecture to generate the multipage pdf content.
Frustrating thing is, this works if I write the data to a file but
not if I
send it to quicklook. I can generate the pdf data with a custom
print info
specifying the page attributes, but quicklook does not display the
content
as multipage. If I use the same settings but a different print
operation,
writing the data to a temporary file instead, I get a correctly
paginated
document.
Code follows.
I understand that PDF content can be created with
CGPDFContextCreate and
the associated begin and end page calls, but the attributed string
doesn't
know about pages, so that seems like a dead end to me. If there's
a method
for doing it that way, I'm all for switching.
You might also suggest just sending RTF to Quick Look, but I'd
like the
text attachments to display. Converting it to html seems like even
more
work.
QuickLook support WebView contents, and the WebView support RTF data.
convert your attributed string into RTF (using -[NSAttributedString
RTFFromRange:documentAttributes:]), then send the data to QuickLook.
You may also generate html from your RTF , but I think the
convertion is sometime less accurate.
Sorry for the noise, I think I should read the whole message before
replying. That said, there is also an -
RTFDFromRange:documentAttributes: method. RTFD should include
attachement, I wonder if there is a way to send the generated data to
a Webview (and so to QuickLook).
