Hi Chris,
thanks for the advice - I know that 8 decimal places is overkill, but I
have tried rounding to a variety of digits; if it rounds up it works, if
it rounds down it doesn't. Your first suggestion works for example, but
rounded to 2 digits doesn't as that is rounded down. I am experimenting
with simply adding a fixed number (0.001) to see if this is enough to
fix it.
Adding digits to a number doesn't make it smaller btw; 0.431 is bigger
than 0.43 - it's only when rounding that a number with more digits can
be smaller than one with less.
Again cheers for the feedback, always appreciated!

Did you perchance try,
pdf2swf -p 1 -s zoom=54.43365479 -s jpegquality=90 -S -z
page_01.pdf -o page_01.swf
pdf2swf -p 1 -s zoom=54.4336548 -s jpegquality=90 -S -z page_01.pdf
-o page_01.swf
pdf2swf -p 1 -s zoom=54.433655 -s jpegquality=90 -S -z page_01.pdf
-o page_01.swf
pdf2swf -p 1 -s zoom=54.43366 -s jpegquality=90 -S -z page_01.pdf
-o page_01.swf
pdf2swf -p 1 -s zoom=54.4337 -s jpegquality=90 -S -z page_01.pdf -o
page_01.swf
pdf2swf -p 1 -s zoom=54.434 -s jpegquality=90 -S -z page_01.pdf -o
page_01.swf
??
Just maybe using .43365478 is rather overdoing the accuracy? Remember
that the more decimal places one adds, the smaller, theoretically, the
number gets.
Regards,
Chris.

Hi all,
I am having a minor issue with swfs being sized incorrectly. An example pdf is
here:
http://ps1.sk.im/7/8/78826/PDFs/page_01.pdf
PDF size info:
width/height: 595.22x842 points (209.98x297.04 mm)
Our system converts pdfs to 450px wide, so I calculate the "-s zoom=" param
with the formulae (450/widthInPoints)*72, this gives me a dpi of 54.43365478
So pdf2swf get run like this:
pdf2swf -p 1 -s zoom=54.43365478 -s jpegquality=90 -S -z PDFs/page_01.pdf -o
hiRes/page_01.swf
This generates an sdf that is 449 pixels wide. Not a huge difference I know,
but it gives us headaches down the line. This happens in about 7% of PDFs that
I convert, and when it does happen it's always 449 - never 451 which is why I
thought it may be a rounding issue.
In case it helps, I get the size info out using pdf2text (www.pdftron.com)
using the command line:
pdf2text --pages 1 --pageinfo PDFs/page_01.pdf
which spits out:
595.22, 842, 0, 0, 595.22, 842, 0, 0, 595.22, 842, 180
which is page width height mw mh pw ph cropLeft
cropBottom nw nh rotation
These dimensions match what I get from Acrobat as well.
Sorry for the long email - I have been trying to fix this for what feels like
my entire natural life.
Cheers all,
ben.
