THSLColor Record

Implements a simple representation of a color in Hue/Saturation/Lum colorspace.

Syntax

THSLColor = record;

Name	Description
Create	Overloaded Create(TUIColor) Create(TColor) Create(Double, Double, Double)
ToColor	Returns a system color from this instance. This method is only needed in C++, in Delphi you can just assign the HslColor to the Color:...[more]
ApplyTint	This method returns the brightness that results from applying tint to brightness.
GetTint	Returns the tint needed to go from originalBrightness to newBrightness. A tint of 0 means no change (OriginalBrightness == NewBrightness), a tint of -1 means NewBrightness = 0, and a tint of 1 means NewBrightness = 1. So this method just does a simple interpolation to find out the needed tint. This method is the inverse of ApplyTint
DistanceSquared	Returns the distance between 2 colors. Not that this is not the euclidean distance, but a distance calculated to improve Hue matching. When converting cell colors, we try to preserve hues, so even a very pale red cell will be converted to bright red and not white or a very pale blue. This make it different from standard color matching as is done when adjusting images to a color palette, and where hue is not as important as here.
Equals	Returns true if both colors are the same.
GetHashCode	Returns a hashcode for the color.
CompareTo	Returns -1 if obj is more than color, 0 if both colors are the same, and 1 if obj is less than color.

Name	Description
Implicit Conversion	Overloaded Implicit conversion from TUIColor to THSLColor Implicit conversion from THSLColor to TUIColor Implicit conversion from TColor to THSLColor Implicit conversion from THSLColor to TColor
Equality	Adapts the = operator so it returns true when both instances have the same values.
Inequality	Adapts the <> operator so it returns true when both instances have different values.
GreaterThan	Adapts the > operator so it returns true when the first parameter is bigger than the second.
LessThan	Adapts the < operator so it returns true when the first parameter is smaller than the second.

Name	Description
Hue	Color hue. (between 0 and 360)
Sat	Color Saturation. (between 0 and 1)
Lum	Color brightness. (between 0 and 1)
R	Red component in the RGB space.
G	Green component in the RGB space.
B	Blue component in the RGB space.
Empty	Returns an empty color.
