Force landscape orientation for printing via CSS

[Laszlo Szilagyi]

Hi,

I'm about to generate PDF files from URLs. Some of the web pages
contains dynamic tables, which can be wider than normal. So sometimes
the edge is cut off.

I need to figure out a solution to handle this situation. I can
compare the page width and the width on the PDF with this code:

renderer = new ITextRenderer(dotsPerPoint, dotsPerPixel);
renderer.setDocument(doc, url);
renderer.layout();

// width of the web page
d = renderer.getRootBox().getPaintingInfo().getOuterMarginCorner();

// width of the PDF page with the current settings
paperWidth =
((PageBox)renderer.getRootBox().getLayer().getPages().get(0)).getContentWidth(null);


Two questions:
1., How can I dynamically change the CSS for a renderer through the
API?
So when I detect that the table is too wide, I may want to switch to
another CSS, which is using landscape orientation.

2., How can I force the landscape mode for printing?
Here's what I've tried:

@page {size: 8.5in 11in landscape; margin: 0.25in;}
body{line-height:1;background-color:red;size: 8.5in 11in
landscape;margin: 0.25in;}

According to the documentation, these should work but they don't work
for me.

Thanks,
Laci

There isn't API to change the in-memory representation of the CSS
files. Your best is probably to modify the DOM and layout/render
again (although other users have found ways around this). You can use
named pages to add a bit of dynamic page size behavior though too.

Regarding (2) that should work. Do you have a sample file that
doesn't work for you?
