Blend modes
The following table summarizes the blend modes available in DrawPlus.
• Top colour refers to the colour superimposed by an object's blend
mode (the object may be a brush stroke, a shape, a photo, etc.).
• Bottom colour refers to the colour of the object onto which the top
colour is applied (e.g., a background).
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.
