Can I use sed (or vi) to edit a PDF? or will it cause bad things to happen?<br />
<br />
I want to change all occurences of <br />
<br />
/Rotate 0<br />
<br />
to <br />
<br />
/Rotate 90<br />
<br />
I was told that this will corrupt the PDF. &nbsp;Something about offsets within the PDF and the change in the file size.<br />
<br />
I haven't run into the problem with acrobat reader 6.0 or 7.0 when viewing the PDF after modifying them in such a fashion.<br />
<br />
Should I be concerned?<br />
<br />
Is there another tool I can use in a UNIX environment to perform the rotate I am trying to achieve?<br />
<br />
If so, what is the tool and the syntax I need to use?<br />
