Details Details

Opacity runs from 0 to 1, with 0 representing perfect transparency.
If an opacity a object with color is placed in front of an object with color , the resulting color will be the blend .
If red and blue with opacity 0.5 are combined, the result is purple—not black, as it would be with physical monochromatic filters. »
Opacity works in both 2D and 3D graphics.
It may take significantly longer to render 3D graphics that involve transparent surfaces.
Graphics that involve transparency may need to be printed as high‐resolution bitmaps.
On many computer systems, objects with opacity a will appear completely transparent if a is too small. »
