<a href='SkColor_Reference#Alpha'>Alpha</a> represents the transparency of <a href='SkColor_Reference#Color'>Color</a>. <a href='SkColor_Reference#Color'>Color</a> with <a href='SkColor_Reference#Alpha'>Alpha</a> of zero is fully
transparent. <a href='SkColor_Reference#Color'>Color</a> with <a href='SkColor_Reference#Alpha'>Alpha</a> of 255 is fully opaque. Some, but not all <a href='undocumented#Pixel'>pixel</a>
formats contain <a href='SkColor_Reference#Alpha'>Alpha</a>. Pixels with <a href='SkColor_Reference#Alpha'>Alpha</a> may store it as unsigned integers or
floating <a href='SkPoint_Reference#Point'>point</a> values. Unsigned integer <a href='SkColor_Reference#Alpha'>Alpha</a> ranges from zero, fully
transparent, to all bits set, fully opaque. Floating <a href='SkPoint_Reference#Point'>point</a> <a href='SkColor_Reference#Alpha'>Alpha</a> ranges from
zero, fully transparent, to one, fully opaque.
