[XeTeX] strange difference

[Apostolos Syropoulos]

Hello,
Thanks for having a look at this problem. I changed a bit the source files
by replacing 

\documentclass[border=9,tikz]{standalone}  

with 
\documentclass[a4paper,landscape]{article}
 Also, I added the command 

\thispagestyle{empty} 

just before the
 \end{document}
Then  compiled the files and then I used pdfcrop to crop the white space.

All files had the same size! Of course now I "understand" what the problem was,but I had the impression that since the image is placed within the bounding boxof the final output, it would not affect its final size. To me this is a bug. And the"recipe" I presented above shows why this is a bug. The bounding box of all imagesis the same.

Kindest regards,
Apostolos

You know that the size of the second \includegraphics with angle=45
is different?

The size of the second \includegraphics is a *square*. If w1 and h1
are the width and height of the first \includegraphics, then
the width w2 and h2 of the second \includegraphics with angle=45 are:

  w2 = h2 = sqrt(1/2) * (w1 + h1)

or
  w2 + h2
  ------- = sqrt(2) ≈ 1.4142
  w1 + h1

Yours sincerely
  Heiko
