Hi Mirek,

To make the image I created it completely with IML designer:
* new empty image
* draw a green opaque circle
* select half of the circle and apply alpha opertor on it

I created another image using the same process ... and didn't get the same result and violet color still appears

I am working on Linux (Fedora 19), it seems that I don't get the same behaviour in the IML designer than you : I don't get the violet color in IML when background is white (see joined images).

1 - ORIGINAL IMAGE:
Starngely, the transparent part looks green in drawing while it appears to be yellow or orange in the color selection part
index.php?t=getfile&id=4379&private=0

index.php?t=getfile&id=4379&private=0

2 - SECOND IMAGE re-created from scratch
index.php?t=getfile&id=4380&private=0

index.php?t=getfile&id=4380&private=0

The application result, when using the new image is the following:
* Violet color is still visible and green+white => grey ???
* Another thing I noticed is that when there is a White background in the layout, the result isn't the same : maybe a painter only issue ?
index.php?t=getfile&id=4382&private=0
