How do you position/move a MPgraphic?

How do you position/move a MPgraphic?

[Daniel Bundzik]

Hi!

How do you position/move a MPgraphic?

Let us us say that you have the MPgraphics "somebackground" and 
"somecolorcircle" (See example below). These MPgraphics are both framed 
and used as a background,  upon which "sometext" is written on. How can 
you freely move or position "somecolorcircle"? ( I want to move 
"somecolorcircle" below "sometext") Naturally, I have read Metafun and 
tried "shifted (x,y)", \definelayer, \setlayer, register, \setMPlayer, 
\getMPlayer...

In general, if you have defined two or more MPgraphics how do you 
position them (In my case "somebackground" is fixed while 
"somecolorcircle" could be anywhere on "somebackground")?

How would you solve this?

Regards,
Daniel

You move the graphic inside the overlay:

\defineoverlay
   [somecolorcircle]
   [\vbox{\kern 5cm\useMPgraphic{somecolorcircle}}]

Best wishes,
Taco

Hi Daniel,

I attached a working example which uses layers. You should take a look 
at the 'details.pdf' manual; link and more information can be found on
http://wiki.contextgarden.net/Layers

Just play around with the layer parameters and see what happens.
'height/width' (for layer definition), 'corner/location' (important to 
understand!) and 'x/y' should be sufficient for most needs. 
'hoffset/voffset' can be handy too, if you want relative positioning.
