Managing masks
Masks are used in some images to prevent unwanted pixels from being
displayed in the user interface (UI).
Items can have two different types of masks:
- 1-bit masks (hard masks)
- 8-bit masks (soft masks)
An 8-bit mask is a greyscale image and allows creation of soft edges
(anti-aliasing), and semi-transparency. The mask type is
component-specific. Generally, 8-bit masks are applicable, unless
otherwise indicated.
Note:
Software vector graphics
(svg) icons are parsed with their own opacity. Separate masks are not
needed.
