|
function GetAverageColor: TBGRAPixel; override; |
|
Returns the average color of the gradient | |
|
function GetAverageExpandedColor: TExpandedPixel; override; |
|
This item has no description. Showing description inherited from TBGRACustomGradient.GetAverageExpandedColor. Returns the average expanded color of the gradient | |
|
function GetColorAt(position: integer): TBGRAPixel; override; |
|
Returns the color at a given ''position''. The reference range is from 0 to 65535, however values beyond are possible as well | |
|
function GetMonochrome: boolean; override; |
|
This item has no description. Showing description inherited from TBGRACustomGradient.GetMonochrome. Returns whether the gradient has only one color | |
