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
