Rotate pdf file less than 90 degree?
You can do that with ConTeXt.
- does not rasterize
- allows for individual angles for individual pages
- allows for varying page sizes
Versions before 2013.10.07 09:47
had a bug which cropped the pages, so make sure you use a version including the fix.
First create a file (e.g. rotatepdf.tex
) with the following content
\getfiguredimensions [\getdocumentargument{input}]
\starttext
\dorecurse{\noffigurepages}
{\startTEXpage
\externalfigure
[\getdocumentargument{input}]
[page=\recurselevel,
orientation=\getdocumentargument{rotation}]
\stopTEXpage}
\stoptext
Then you can rotate a PDF using the following command line:
context --input=somefile.pdf --rotation=10 rotatepdf.tex
Here is an example output:
I looked hard and long and could find no tool that allowed you to do this interactively that is a native PDF viewer type of tool. I did not try this but you might be able to use Inkscape or Gimp to do this. I think the only issue you'll likely run into with using them is the ability to batch rotate a multi-page document.
Even the command line tools such as PdfTk couldn't do rotation by degrees, which really surprised me.
However using ImageMagick you can rotate PDF files in 1 degree increments.
Examples
$ convert original.pdf -rotate 45 rot45.pdf
You can put any value you want in for the rotate argument. It will also take negative numbers so this is possible:
$ convert original.pdf -rotate -45 rot-45.pdf
The quality of the output will drop off dramatically using the default options so you'll likely need to include the -density
switch to increase the quality of the resulting PDF file.
$ convert -density 300x300 original.pdf -rotate 45 rot45.pdf
Resulting PDF
Here's a screenshot of Evince with the resulting PDF file.
This has also been asked on stackoverflow.com.
Another option is using LaTeX:
\documentclass{standalone}
\usepackage{graphicx}
\begin{document}
\includegraphics[angle=-1.5]{odd-scan}
\end{document}
In this case, I have the file odd-scan.pdf
(a slightly rotated one page scan) in the same folder as the LaTeX file rotated.tex
with the content above and then I run pdflatex rotated.tex
. The output is a file rotated.pdf
with the PDF rotated by 1.5 degrees clockwise.
