CorelDRAW transparency operations

15/06/2009

There are 19 Transparency operation presets in CorelDRAW. These operations (also known as “Merge modes“) enable different overlaying options and are dependent on the colors of the transparent object and the objects under it since they specify how those colors are combined.

Here are a few previews of each transparency operation used on the same transparent text frame sitting on the same background color. Remember that each one of them may not look too exciting on its own, but combining it with other creative effects makes some really-really cool designs for web-to-print and dynamic imaging templates.

CorelDRAW no transparency
No transparency
/
/
CorelDRAW normal transparency
Normal
Applies the transparency color on top of the base color
CorelDRAW add transparency
Add
Adds the values of the transparency color and the base color
/
CorelDRAW subtract transparency
Subtract
Adds the values of the transparency color and the base color together, and then subtracts 255
CorelDRAW difference transparency
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.
/
/
CorelDRAW multiply transparency
Multiply
Multiplies the base color by the transparency color, and 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.
CorelDRAW divide transparency
Divide
Divides the base color by the transparency color, or conversely, divides the transparency color by the base color, depending on which color has the higher value
CorelDRAW If lighter transparency
If lighter
Replaces any base color pixels that are a darker color with the transparency color. Base color pixels that are lighter than the transparency color are not affected.
/
CorelDRAW If darker transparency
If darker
Replaces any base color pixels that are a lighter color with the transparency color. Base color pixels that are darker than the transparency color are not affected.
CorelDRAW texturize transparency
Texturize
Converts the transparency color to grayscale, and then multiplies the grayscale value by the base color
/
CorelDRAW hue transparency
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.
CorelDRAW saturation transparency
Saturation
Uses the lightness and hue of the base color and the saturation of the transparency color
/
/
/
CorelDRAW lightness transparency
Lightness
Uses the hue and saturation of the base color and the lightness of the transparency color
/
/
CorelDRAW invert transparency
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.
CorelDRAW logical AND transparency
Logical AND
Converts the transparency and base colors to binary values, and then applies the Boolean algebraic formula AND to these values
CorelDRAW logical OR transparency
Logical OR
Converts the transparency and base colors to binary values, and then applies the Boolean algebraic formula OR to these values
/
CorelDRAW logical XOR transparency
Logical XOR
Converts the transparency and base colors to binary values, and then applies the Boolean algebraic formula XOR to these values
CorelDRAW red transparency
Red
Applies the transparency color to the red channel of RGB objects
/
/
CorelDRAW green transparency
Green
Applies the transparency color to the green channel of RGB objects
CorelDRAW blue transparency
Blue
Applies the transparency color to the blue channel of RGB objects
