Enum tetra::graphics::BlendMode[][src]

pub enum BlendMode {
    Alpha(BlendAlphaMode),
    Add(BlendAlphaMode),
    Subtract(BlendAlphaMode),
    Multiply,
}
Expand description

The different ways of blending colors.

The active blend mode will be used to determine how drawn content will be blended with the screen (or with a Canvas, if one is active).

For modes where the alpha component of the color can affect the output, an additional BlendAlphaMode parameter is provided, which determines if the colour should be multiplied by its alpha before blending.

Variants

The alpha of the drawn content will determine its opacity.

This is the default behaviour.

The pixel colors of the drawn content will be added to the pixel colors already in the target. The target’s alpha will not be affected.

Subtract(BlendAlphaMode)

The pixel colors of the drawn content will be subtracted from the pixel colors already in the target. The target’s alpha will not be affected.

Multiply

The pixel colors of the drawn content will be multiplied with the pixel colors already in the target. The alpha component will also be multiplied.
