pub struct BlendState { /* private fields */ }
Expand description
Pixel arithmetic description for blending operations.
Will be used in an equation:
equation(sfactor * source_color, dfactor * destination_color)
Where source_color is the new pixel color and destination color is color from the destination buffer.
Example:
BlendState::new(
Equation::Add,
BlendFactor::Value(BlendValue::SourceAlpha),
BlendFactor::OneMinusValue(BlendValue::SourceAlpha)
);
This will be source_color * source_color.a + destination_color * (1 - source_color.a)
Wich is quite common set up for alpha blending.
