## Description¶

Applies operator to two color inputs.

## Properties¶

 Operator operator `0`

## Enumerations¶

enum Operator:

Operator OP_SCREEN = `0`

Produce a screen effect with the following formula:

```result = vec3(1.0) - (vec3(1.0) - a) * (vec3(1.0) - b);
```

Operator OP_DIFFERENCE = `1`

Produce a difference effect with the following formula:

```result = abs(a - b);
```

Operator OP_DARKEN = `2`

Produce a darken effect with the following formula:

```result = min(a, b);
```

Operator OP_LIGHTEN = `3`

Produce a lighten effect with the following formula:

```result = max(a, b);
```

Operator OP_OVERLAY = `4`

Produce an overlay effect with the following formula:

```for (int i = 0; i < 3; i++) {
float base = a[i];
float blend = b[i];
if (base < 0.5) {
result[i] = 2.0 * base * blend;
} else {
result[i] = 1.0 - 2.0 * (1.0 - blend) * (1.0 - base);
}
}
```

Operator OP_DODGE = `5`

Produce a dodge effect with the following formula:

```result = a / (vec3(1.0) - b);
```

Operator OP_BURN = `6`

Produce a burn effect with the following formula:

```result = vec3(1.0) - (vec3(1.0) - a) / b;
```

Operator OP_SOFT_LIGHT = `7`

Produce a soft light effect with the following formula:

```for (int i = 0; i < 3; i++) {
float base = a[i];
float blend = b[i];
if (base < 0.5) {
result[i] = base * (blend + 0.5);
} else {
result[i] = 1.0 - (1.0 - base) * (1.0 - (blend - 0.5));
}
}
```

Operator OP_HARD_LIGHT = `8`

Produce a hard light effect with the following formula:

```for (int i = 0; i < 3; i++) {
float base = a[i];
float blend = b[i];
if (base < 0.5) {
result[i] = base * (2.0 * blend);
} else {
result[i] = 1.0 - (1.0 - base) * (1.0 - 2.0 * (blend - 0.5));
}
}
```

Operator OP_MAX = `9`

Represents the size of the Operator enum.
