Hi,

In metapost (running metafun) the following does not work:

draw image (
     draw fullcircle scaled 20cm withpen pencircle scaled 20mm withcolor 
red   withtransparency (1,.40) ;
     draw fullcircle scaled 15cm withpen pencircle scaled 15mm withcolor 
green withtransparency (1,.30) ;
     draw fullcircle scaled 10cm withpen pencircle scaled 10mm withcolor 
blue  withtransparency (1,.20) ;
)
     withcolor blue
     withtransparency (1,.125) % selectively applied
     withpen pencircle scaled 10mm
;

Here the last transparency gets only applied to the first element of the 
picture.

For this reason, the following new variants of 'image' are provided:

decorated   : adds to the current properties, last one wins
redecoreated: replaces the current properties (color and transparency 
only, pens are kept)
undecorated : ignores the specification

This will work with the upcoming metapost/mplib release but I like to 
mention it now (before I forget).

Hans
