The quality of the rotated pdfs, which are images, drops off a little.
For example, some characters are not so sharp as in the original pdf.

If I use GraphicsMagick I would remedy this with the parameter -density
as in:
gm convert -density 300x300 original.pdf -rotate 45 rotated.pdf

Thanks, it works fine.

I noticed that the resolution of the rotated pages decreases. Is there
any possibility to maintain or increase the resolution of the rotated
pages?

Many thanks in advance,

[NTG-context] rotating some pages of a pdf

2017-01-04 Thread Cesar Romani 

I'm using the following code, rotate.tex, to rotate all the pages of
file.pdf, using: context --input=file.pdf --rotation=45 rotate.pdf

rotate.tex
==
\getfiguredimensions [\getdocumentargument{input}]
\starttext
  \dorecurse{\noffigurepages}
{\startTEXpage
  \externalfigure
[\getdocumentargument{input}]
[page=\recurselevel,
 orientation=\getdocumentargument{rotation}]
\stopTEXpage}
\stoptext

How could I use this code to rotate, say, the page five, 7º clockwise,
and the page twenty, 15º counterclockwise?

Many thanks in advance,
