bool BLRgba::isOpaque() constconstexprnoexcept[¶]

Tests whether the color is fully-opaque (alpha equals 1.0).

bool BLRgba::isTransparent() constconstexprnoexcept[¶]

Tests whether the color is fully-transparent (alpha equals 0.0).

float BLRgba::r[¶]

Red component.

float BLRgba::g[¶]

Green component.

float BLRgba::b[¶]

Blur component.

float BLRgba::a[¶]

Alpha component.
