getTheme

public int getTheme()

Index into the clrScheme collection, referencing a particular sysClr or srgbClr value expressed in the Theme part.

getTheme in class ExtendedColor

Returns:

Index of Theme color, if ExtendedColor.isThemed() is true

setTheme

public void setTheme(int theme)

Index into the clrScheme collection, referencing a particular sysClr or srgbClr value expressed in the Theme part.

Parameters:

theme - index

getTint

public double getTint()

Specifies the tint value applied to the ctColor.

If tint is supplied, then it is applied to the RGB value of the ctColor to determine the final ctColor applied.

The tint value is stored as a double from -1.0 .. 1.0, where -1.0 means 100% darken and 1.0 means 100% lighten. Also, 0.0 means no change.

In loading the RGB value, it is converted to HLS where HLS values are (0..HLSMAX), where HLSMAX is currently 255.

Here are some examples of how to apply tint to ctColor:

 If (tint < 0)
 Lum' = Lum * (1.0 + tint)

 For example: Lum = 200; tint = -0.5; Darken 50%
 Lum' = 200 * (0.5) => 100
 For example: Lum = 200; tint = -1.0; Darken 100% (make black)
 Lum' = 200 * (1.0-1.0) => 0
 If (tint > 0)
 Lum' = Lum * (1.0-tint) + (HLSMAX - HLSMAX * (1.0-tint))
 For example: Lum = 100; tint = 0.75; Lighten 75%

 Lum' = 100 * (1-.75) + (HLSMAX - HLSMAX*(1-.75))
 = 100 * .25 + (255 - 255 * .25)
 = 25 + (255 - 63) = 25 + 192 = 217
 For example: Lum = 100; tint = 1.0; Lighten 100% (make white)
 Lum' = 100 * (1-1) + (HLSMAX - HLSMAX*(1-1))
 = 100 * 0 + (255 - 255 * 0)
 = 0 + (255 - 0) = 255
 

Specified by:

getTint in class ExtendedColor

Returns:

the tint value

setTint

public void setTint(double tint)

Specifies the tint value applied to the ctColor.

If tint is supplied, then it is applied to the RGB value of the ctColor to determine the final ctColor applied.

The tint value is stored as a double from -1.0 .. 1.0, where -1.0 means 100% darken and 1.0 means 100% lighten. Also, 0.0 means no change.

In loading the RGB value, it is converted to HLS where HLS values are (0..HLSMAX), where HLSMAX is currently 255.

Here are some examples of how to apply tint to ctColor:

 If (tint < 0)
 Lum' = Lum * (1.0 + tint)

 For example: Lum = 200; tint = -0.5; Darken 50%
 Lum' = 200 * (0.5) => 100
 For example: Lum = 200; tint = -1.0; Darken 100% (make black)
 Lum' = 200 * (1.0-1.0) => 0
 If (tint > 0)
 Lum' = Lum * (1.0-tint) + (HLSMAX - HLSMAX * (1.0-tint))
 For example: Lum = 100; tint = 0.75; Lighten 75%

 Lum' = 100 * (1-.75) + (HLSMAX - HLSMAX*(1-.75))
 = 100 * .25 + (255 - 255 * .25)
 = 25 + (255 - 63) = 25 + 192 = 217
 For example: Lum = 100; tint = 1.0; Lighten 100% (make white)
 Lum' = 100 * (1-1) + (HLSMAX - HLSMAX*(1-1))
 = 100 * 0 + (255 - 255 * 0)
 = 0 + (255 - 0) = 255
