Maybe I was just thinking too far out of the box, but I was wondering if
it's possible to create output with different pages having different
orientation.
I tried just swapping the page-height and page-width attribute values
and had a couple of issues with it. For a PDF, if I set the first page
to portrait and the second page to landscape it was making both pages
landscape. On getting the output directly to the printer that was
somehow selecting the wrong tray.
I've tried setting the reference-orientation value to 90. I haven't
gotten a test that worked with portrait and landscape in the same
output, but this works well for landscape directly to the printer. The
problem with this value is when I create a PDF and try to view it, the
pages actually show as sideways.
On sending output directly to the printer I'm actually generating a
pageable object from the FOP output and using the
javax.print.PrintService class. I was wondering if just setting the
javax.print.attribute.standard.PresentationDirection and/or
javax.print.attribute.standard.OrientationRequested value would work
best for printing landscape, though of course this would not allow
portrait and landscape pages in the same output.
The only other way I can think of to get portrait and landscape
orientation in the same output would be to create different xml files
for each and process them separately, though of course this would
require some method of combining the output to get one PDF, and it would
break xsl code like fo:page-number-citation ref-id="last-page".

I'm using the reference-orientation=90 as a workaround until I get time
to test to get the other way to work.
The 90 reference prints fine. It just doesn't look right. If I load it
into preview or PDF it's just portrait turned sideways, so they have to
turn their head or their screen to read it.
I'll have to look at the one program we have thus far using landscape
but I believe it came out correct to PDF with appearance of 11" width
but never printed right. We had some users testing that program but it
wasn't actually implemented yet. It will be soon so I will need to
figure out how this should really work.

Hi Eric
I tried mine with option 2 and the landscape page does indeed print out
portrait.
So if you want a landscape page in the middle of portrait pages for
viewing only, option 2 is the better option. If you want the same to
print only, option 1 is the best. If you want both I think you have a
problem.
I am not sure if this would be considered a bug or something that could
be considered for a future FOP release.
Are you able to use two separate stylesheets, one using each option?
Kind regards
Stuart Scott

That is the reference-orientation=90 option I tried. That works well,
though I don't think users want to view it sideways.
There are 2 ways to print landscape, I've determined. See attached.
The first one involves setting page-height=11" and page-width=8.5" and
reference-orientation=90.
The second one involves setting page-height=8.5" and page-width=11" and
reference-orientation=0.
The issues with that:
1. The first method prints fine if I create a pageable object from the
FOP output (using embedded code with the output stream) and send it
straight to the printer using the Java PrintService with default
options, only assigning JobName.
The second method sent straight to the printer goes to tray 1 (manual
feed) instead of the default tray 3, asking for 8.50" x 11.00" paper,
and after putting the paper in it prints portrait.
2. I couldn't figure out how to get the second method working with mixed
output, getting one page to print portrait and the next to print
landscape.
The first method seems unusable if it can't turn sideways by default
when the users view the PDF, to read like the second one.
The second method seems unusable if I can't get it to come out on the
printer like the first one does.

RE: Placing the minus sign(-) to the RIGHT side of the number

I believe changing the format string to "##,###.00 ;#####.00-" (note the space before the semicolon) should do the trick.

Subject: Placing the minus sign(-) to the RIGHT side of the number
I am using FOP to produce an invoice in a .PDF. Everything works.
However, when a negative number is produced in my right justified table column, the minus sign causes the decimal point to be mis-aligned.
I found the "format-number" function and this addresses the problem. Now the issue is that my system generates a negative value in the form of:
233.94-
(the minus sign is always to the right of the value) This cannot be changed. When I submit the value to "format-number", it returns a "NaN" error.
select="format-number(inv-amt,'##,###.00;#####.00-')"
In summary, I need to produce a column of numbers, right justified, some of the values are negative with the minus sign to the right. At the same time, the vertical alignment of the decimal point is required.
Any ideas?
Thanks.

AW: Placing the minus sign(-) to the RIGHT side of the number
Posted by Georg Datterl <ge...@geneon.de>.
Hi Jeff,
If your problem is a simple format-number problem, maybe your are missing a , in the second definition.
If you need the - after the number, I'd guess the only way is to fake it. Either by using two columns, one with the numbers, the other with the sign, or by adding a right padding in blocks with positive numbers. I don't think you can tell fop to align blocks not based on their border but on a part of their content.

This seems relatively simple.
I assume the problem is that your data has 233.94- and
format-number requires -223.94.
I don't know the syntax offhand but there is a method in the xsl
to check the last character of the data field.
You could just use the value of (if {last character} = "-") for
an xsl:choose condition to parse the inv-amt input field, to move the
"-" to the front with a concat() function then pass the result into the
format-number.
(of course it's even easier the way I did it, where the program
generating the XML data already formats numbers into text and calculates
absolute positioning to print them)

RE: Orientation
Posted by Eric Douglas <ed...@blockhouse.com>.
If I assign the page-height=11" and page-width=8.5" and
reference-orientation=90 it works perfectly, except the PDF and print
preview appear sideways.
If I assign the page-height=8.5" and page-width=11" and
reference-orientation=0 it works for PDF and print preview but really
confuses the printer. After prompting for paper in the manual feed
tray, the printer prints it landscaped on portrait, so it's running off
the right edge and cutting off the bottom.
There is a workaround for this, but is there a solution? The most
obvious workaround is to transform it both ways keeping 2 copies in
memory, one for preview and PDF and one for sending to the printer.
This is acceptable only if the transform is a fast process and the
memory usage is small enough where doubling it is not a concern. I
can't reasonably hold just one or the other in memory if I want to be
able to send it to the printer while the preview is active...

portrait and landscape pages in the same output.
The only other way I can think of to get portrait and landscape
orientation in the same output would be to create different xml files
for each and process them separately, though of course this would
require some method of combining the output to get one PDF, and it would
break xsl code like fo:page-number-citation ref-id="last-page".
