I had some mystery alpha - an object was semi-transparent when all of the alpha properties (stroke, fill, color, and layer) were set at 100% in Inkscape.
I traced the culprit to style="opacity:0.45" in the XML below.
What could I have done wrong, or Inkscape done wrong, to cause this value to no longer register accurately in Inkscape?



This is an object that has been copied across several project files, and although originally I had set the alpha with one of the sliders, at some point the XML and Inkscape started to disagree.
Has anyone experienced something like this before?
It was easy to fix the XML but I'd like to avoid it recurring in the future. Thanks.

Can imagine it was part of a group with transparency, that got ungrouped.

Usually such problem would appear the other way: using the dropper tool on objects with transparency would add alpha to the fill and preserve opacity of the selected object.

I see!
Got busy after posting but just checked back and want to say thanks for the reply.
