How to reset text on a new page?
Hi,
I get that one starts text with contentStream.beginText() and ends text
with contentStream.endText(). And I get that one gets a new page with doc
.addPage(page). But when I use all this to print two pages, I end up with
two pages each with the same text (the merge of the contents of the two
pages). How can I clear the page contents for a new page? (I didn't see
an example that printed two pages in the examples.)
Thanks!

I should have stated that I am using 2.x.
Thanks.

Thanks. I actually got it working. I have even switched between text mode
and line drawing mode. I'm now working on being able to switch back to
text mode.
Thanks for the help!

No. It is possible to have the same content stream for several pages. It
is even possible to have the same page object several times. This is
possible, but would not be very useful, obviously. And that may be what
happened to you.
And it is also possible to have an array of content streams for one
page, but that is a different story.
If still you don't know what went wrong, please post your code (rather,
the shortest possible code that reproduces the problem).

Thanks, but getting a little confused here. Let me ask this:
Each page in a document has its own PDPageContentStream _and_ PDPage. This
means that there is a one-to-one relationship between PDPageContentStream's
and PDPage objects. Is that (always) true?
Thanks.

You must create a new content stream object for each page. And of course
also a new PDPage object too.
