placing image on layer is sketchy

placing image on layer is sketchy

Hello,

still working on the CD booklet ;-)

While trying to include the pictures I have some problems with placing a 
picture onto a layer: The following code should place the picture into the 
lower right corner of the upper part and then goes to the left. The part that 
goes over the page border is for the bleeding.
But the result (as seen in the attached pdf) is a sketchy position of the 
right, bottom corner it looks like the same offset in x and -y direction.

Two more observations:
- with the "offset=-1mm" in the layerframe configuration there is only an 
offset in -y direction left (offset=0mm is not enough)
- without the frame it works as expected (and so my problem is solved)

\setuppapersize[CD][CD,oversized]
\setuppagenumbering[location=,state=stop]

\setuplayout
  [location=middle]

\showframe[edge]

\useexternalfigure[page12][dummy]

\definelayer
  [p12]
  [width=\paperwidth,
  height=\paperheight]

\setlayerframed [p12]
  [x=\paperwidth,y=74mm,
  location={left,top}]
  [width=124mm,height=77mm,
  %offset=-1mm,
  frame=on]
  {\externalfigure[page12][width=126mm,height=77mm]}
%\setlayer [p12]
%  [x=\paperwidth,y=74mm,
%  location={left,top}]
%  {\externalfigure[page12][width=124mm,height=77mm]}

\starttext
\setupbackgrounds[page][background=p12]
\startstandardmakeup
\stopstandardmakeup
\stoptext

grep for

\definelayerpreset

using preset is easier

preset=lefttop,offset=2mm,x=3mm,y=4mm

there's also hoffset and voffset so that you can use offset per layer 
and per placement

x, y, offset are all relative to the corner

\setlayer
  [p12]
  [preset=righttop,
   voffset=74mm]
  {\offset[location=rt,rightoffset=-3mm]
     {\tlap{\externalfigure[page12][width=\dimexpr\paperwidth+6mm\relax,height=77mm]}}}
