| Class | Description |
|---|
| AlphaBiLevel | Represents an Alpha Bi-Level effect. Alpha (Opacity) values less than the threshold are changed to 0 (fully transparent) and alpha values greater than or equal to the threshold are changed to 100% (fully opaque). |
| AlphaCeiling | Represents an Alpha Ceiling effect. Alpha (opacity) values greater than zero are changed to 100%. In other words, anything partially opaque becomes fully opaque. |
| AlphaFloor | Represents an Alpha Floor effect. Alpha (opacity) values less than 100% are changed to zero. In other words, anything partially transparent becomes fully transparent. |
| AlphaInverse | Represents an Alpha Inverse effect. Alpha (opacity) values are inverted by subtracting from 100%. |
| AlphaModulate | Represents an Alpha Modulate effect. Effect alpha (opacity) values are multiplied by a fixed percentage. The effect container specifies an effect containing alpha values to modulate. |
| AlphaModulateFixed | Represents an Alpha Modulate Fixed effect. Effect alpha (opacity) values are multiplied by a fixed percentage. |
| AlphaReplace | Represents and Alpha Replace effect. Effect alpha (opacity) values are replaced by a fixed alpha. |
| BiLevel | Represents a Bi-Level (black/white) effect. Input colors whose luminance is less than the specified threshold value are changed to black. Input colors whose luminance are greater than or equal the specified value are set to white. The alpha effect values are unaffected by this effect. |
| Blur | Represents a Blur effect that is applied to the entire shape, including its fill. All color channels, including alpha, are affected. |
| ColorChange | Represents a Color Change effect. Instances of clrFrom are replaced with instances of clrTo. |
| ColorReplace | Represents a Color Replacement effect. All effect colors are changed to a fixed color. Alpha values are unaffected. |
| Duotone | Represents a Duotone effect. For each pixel, combines clr1 and clr2 through a linear interpolation to determine the new color for that pixel. |
| FillOverlay | Represents a Fill Overlay effect. A fill overlay may be used to specify an additional fill for an object and blend the two fills together. |
| GrayScale | Represents a Gray Scale effect. Converts all effect color values to a shade of gray, corresponding to their luminance. Effect alpha (opacity) values are unaffected. |
| HSL | Represents a Hue/Saturation/Luminance effect. The hue, saturation, and luminance may each be adjusted relative to its current value. |
| Luminance | Represents a Luminance effect. Brightness linearly shifts all colors closer to white or black. Contrast scales all colors to be either closer or further apart. |
| Tint | Represents a Tint effect. Shifts effect color values towards/away from hue by the specified amount. |
