Re-render

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I currently am working on a 2 page document.First time I create it everything is as expected.

The problem starts when I want to re-render to update it.
My process is the same for each render:
Delete All Pages (1 to PageCount)
Select Page 1  (always exists according to the documentation)
Add Page elements
New Page
Select Page 2
Add Page Elements.

On the second time through page 2 is overwriting page 1, but it is also on page 2 as well.
I can't figure out what I am missing.

I have just discovered that if I do NewPage after deleting all pages then it works as expected, except that I end up with a page 3. So all is well if I then delete page 3.
Seems inconsistent to me.

What should I be doing?

	PDF are picky about ContentStreams. We have encountered problems with pages overprinting each other as well, although under different circumstances. PDF allows you to create a content stream object and reuse it on more than one page. This can become problematic if you are not careful. You may need to be using ContentStreamSafe() and/or NewContentStream() to ensure the pages remain separate.
