Trait Implementations

The resulting type after applying the + operator.

Performs the + operation. Read more

The resulting type after applying the + operator.

Performs the conversion.

The core color type. Typically Self for color types without alpha.

Convert the color to premultiplied alpha.

Convert the color from premultiplied alpha.

Blend self, as the source color, with destination, using blend_function. Anything that implements BlendFunction is acceptable, including functions and closures. Read more

Place self over other. This is the good old common alpha composition equation. Read more

Results in the parts of self that overlaps the visible parts of other. Read more

Results in the parts of self that lies outside the visible parts of other. Read more

Place self over only the visible parts of other.

Results in either self or other, where they do not overlap.

Add self and other. This uses the alpha component to regulate the effect, so it’s not just plain component wise addition. Read more

Multiply self with other. This uses the alpha component to regulate the effect, so it’s not just plain component wise multiplication. Read more

Make a color which is at least as light as self or other.

Multiply self or other if other is dark, or screen them if other is light. This results in an S curve. Read more

Return the darkest parts of self and other.

Return the lightest parts of self and other.

Lighten other to reflect self. Results in other if self is black. Read more

Darken other to reflect self. Results in other if self is white. Read more

Multiply self or other if other is dark, or screen them if self is light. This is similar to overlay, but depends on self instead of other. Read more

Lighten other if self is light, or darken other as if it’s burned if self is dark. The effect is increased if the components of self is further from 0.5. Read more

Return the absolute difference between self and other. It’s basically abs(self - other), but regulated by the alpha component. Read more

Similar to difference, but appears to result in a lower contrast. other is inverted if self is white, and preserved if self is black. Read more
