Fills, Lines, Colours, and Transparency 107
Setting opacity
Key point! In DrawPlus, opacity is a property of colour, and can be
set directly from the Colour tab. 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 is 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.
