In my app I am generating HTML and want to create a PDF based on the

After lots of searching (list archives, Google, and so on) I have
gotten
some code working that will create a PDF file that is properly
paginated,
but in my case I want the PDF in memory not on disk.

I was hoping the WebView would be able to paginate by itself. I am
also a
web developer and I know there are CSS attributes out there that help
control printing so I am a little hesitant to manually cut out
pages since
I'd like to honor any Print CSS that is being used in the HTML.
I don't know about CSS and some of the other things. In the WebKit
sample code (installed in /Developer/Examples/WebKit on my machine)
is a project called CarbonWeb.
At one point in the past, the CarbonWeb printing code would generate
a PDF from a paginated web view (in memory using
dataWithPDFInsideRect:) and then print the resulting PDF . At the
time the pagination was done using the pagination routines of
NSView. It looks like the code has been modified since I implemented
that so that it is using a NSPrintOperation to do the pagination but
it should be fairly easy to pick up the PDF pages as they are
generated and stuff them into a CGPDFDocument in memory.
