Dear list,

I have the following imposition sample:

  \startbuffer[newbuff]
  \showframe\showgrid
  \setuppapersize[A3, landscape]
  \setuplayout[width=middle]
  \starttext
  \dorecurse{4}{\null\page}
  \stoptext
  \stopbuffer
  \startmode[*first]
  \savebuffer[newbuff][A3page.tex, prefix=no]
  \executesystemcommand{context --purgeall A3page.tex}
  \stopmode
  \showframe
  \setuplayout[page]
  \setuppapersize[A5][A4, landscape]
  \setuparranging [2UP]
  \setupinteractionscreen[option={landscape, paper}]
  \starttext
  \doiffile{A3page.pdf}
  {\def\Doc{A3page.pdf}
  \getfiguredimensions[\Doc]
  \dorecurse{\noffigurepages}
    {\ifodd\recurselevel
      \rotate[rotation=90]
        {\externalfigure[\Doc][page=\recurselevel, width=\textheight]}
    \else\rotate[rotation=270]
        {\externalfigure[\Doc][page=\recurselevel, width=\textheight]}
    \fi}}
  \stoptext

I’m afraid that if rotation values are 270 or 180, the imposed page has
an extra vertical space before.

I think this might be a bug. Or I don’t know what I might be missing.

Many thanks for your help,

Pablo

nicer demo:

\showframe

\starttext
     \topskip4cm
     \dostepwiserecurse{0}{360}{10}{
 
\ruledhbox{\rotate[rotation=#1]{\blackrule[width=\textheight,height=\textwidth,depth=0cm,color=darkred]}}
     }
     \dostepwiserecurse{0}{360}{10}{
 
\ruledhbox{\rotate[rotation=#1,location=high]{\blackrule[width=\textheight,height=\textwidth,depth=0cm,color=darkgreen]}}
     }
     \dostepwiserecurse{0}{360}{10}{
 
\ruledhbox{\rotate[rotation=#1,location=fit]{\blackrule[width=\textheight,height=\textwidth,depth=0cm,color=darkblue]}}
     }
     \dostepwiserecurse{0}{360}{10}{
 
\ruledhbox{\rotate[rotation=#1,location=middle]{\blackrule[width=\textheight,height=\textwidth,depth=0cm,color=darkcyan]}}
     }
     \dostepwiserecurse{0}{360}{10}{
 
\ruledhbox{\rotate[rotation=#1,location=depth]{\blackrule[width=\textheight,height=\textwidth,depth=0cm,color=darkmagenta]}}
     }
     \dostepwiserecurse{0}{360}{10}{
 
\ruledhbox{\rotate[rotation=#1,location=broad]{\blackrule[width=\textheight,height=\textwidth,depth=0cm,color=darkyellow]}}
     }
\stoptext

Hans,

many thanks for your reply and your sample.

A more visual version for me would be:

  \setupbodyfont[sans, 30pt]
  \setuppagenumbering[location=,]
  \showframe

  \starttext
       \topskip4cm
          \dostepwiserecurse{0}{360}{10}{
  \doloopoverlist{normal,default,depth,fit,broad,high,middle}{
  \ruledhbox{\rotate[rotation=\recurselevel, location=\recursestring]{%
  \framed
     [width=\textheight, height=\textwidth, rulethickness=5pt,
      depth=0cm, foregroundstyle=\bfd]
    {\recursestring, \recurselevel°}
              }
          }
      }
  }
  \stoptext

I have just added it to
https://wiki.contextgarden.net/Scaling_Rotating_Mirroring_Clipping#Rotating_Figures.

Many thanks for your help,

Pablo
