Setting opacity
Key point! In DrawPlus, opacity is a property of colour; both can be
set in the Colour tab in combination. Transparency refers to object-
based gradient or bitmap transparency effects, set via the
Transparency tab or Transparency Tool.
Opacity is great for highlights, shading and shadows, and simulating "rendered"
realism. It can make the difference between flat, ordinary visuals and sparkling
realism!
Opacity in the inverse of transparency—fully opaque (100%) is no transparency
(0%), and vice versa. It works rather like fills that use "disappearing ink" instead
of colour. The less opacity in a particular spot, the more "disappearing" takes
place there, and the more the object(s) underneath show through.
