    Subject: Proposal/clarification for "draw:opacity"


    Dear TC members,
    
    The currrent specification contains a graphic property called 
    "draw:opacity". This property actually has two purposes
    
    a) It specifies the opacity of the fill area of a drawing object. That's 
    described in section 14.14.2. (The specification uses the term graphic 
    objects instead of drawing object. I think that's a typo that should be 
    fixed).
    b) It specifies the opacity of the bitmap used by an image shape. This 
    is specified in section 14.17.9.
    
    Unfortunately, this definition is ambiguous, because an image object in 
    fact can contain a background in addition to the bitmap data. This means 
    opacity of the bitmap data and the background cannot be controlled 
    independently.
    
    I suggest to resolve this issue by renaming the attribute specified in 
    section 14.17.9 to "draw:image-opacity".
    
    Best regards
    
    Michael
