Kevin and Jasper hit the nail on the head (Jasper's comment that the
words are usually associated with particular ranges is mostly true
AFAIRemember, but I can't guarantee it).
If there is part of the documentation here that could be made clearer,
let us know...
My understanding is alpha and opacity are same just different range.
Opacity is 0.0 to 1.0
Alpha is 0 to 255
Jim or Kevin will be authority on this.

I'm sure Jim could word this better, but here goes...
Opacity and alpha are mostly used interchangeably. Whether the range is
expressed as a normalized value [0.0,1.0] or an 8-bit pixel value
[0,255], the meaning is the same. A value of 0 means that the color is
completely transparent. When
Hi,
Yes it looks like i mixed this up with transparency!

Hi,
Maybe I'm completely wrong but to me it looks like the opacity I get
from Image.getPixelReader.getColor() is wrong.
If not mistaken the relation between alpha and opacity is expressed with:
opacity = (255 - alpha) / 255.0
which means:
opacity 0 = alpha 255
opacity 1 = alpha 0
Running the
