To apply merge modes

1 Using the Interactive Transparency tool, click the fountain, textured, or pattern transparency.

2 Choose one of the following merge modes from the Transparency

Operation list box on the Property Bar.

• Normal — applies the transparency color on top of the base color

• Add — adds the values of the transparency color and the base color

• Subtract — adds the values of the transparency color and the base color together, then subtracts 255

• Difference — subtracts the transparency color from the base color and multiplies by 255. If the transparency color value is 0, the result will always be 255

• Multiply — multiplies the base color by the transparency color, then divides by 255. This has a darkening effect unless you are applying color to white. Multiplying black with any color results in black. Multiplying white with any color leaves the color unchanged

• Divide — divides the base color by the transparency color, or vice versa, depending on which color has the higher value

• If Lighter — replaces any base pixels that are a darker color with the transparency color. Base pixels that are lighter than the transparency color are not affected

• If Darker — replaces any base pixels that are a lighter color with the transparency color. Base pixels that are darker than the transparency color are not affected

• Texturize — converts the transparency color to grayscale, then multiplies the grayscale value by the base color

• Hue — uses the hue of the transparency color as well as the saturation and lightness of the base color. If you are adding color to a grayscale image, there will be no change because the colors are desaturated

• Saturation — uses the lightness and hue of the base color and the saturation of the transparency color

• Lightness — uses the hue and saturation of the base color and the lightness of the transparency color

• Invert — uses the transparency color's complementary color. If a transparency color value is 127, there will be no change because the color value falls in the center of the Color Wheel

• Logical AND — converts the transparency and base colors to binary values, then applies the Boolean algebraic formula AND to these values

• Logical OR — converts the transparency and base colors to binary values, then applies the Boolean algebraic formula OR to these values

• Logical XOR — converts the transparency and base colors to binary values, then applies the Boolean algebraic formula XOR to these values

• Red — applies the transparency color to the red channel of RGB images

• Green — applies the transparency color to the green channel of RGB images

• Blue — applies the transparency color to the blue channel of RGB images
