Color Property
Gets or sets the currently selected color in the RGB color model.
public Avalonia.Media.Color Color { get; set; }
Remarks
Use this property instead of Avalonia.Controls.Primitives.ColorSlider.HsvColor when in Avalonia.Controls.ColorModel.Rgba to avoid loss of precision and color drifting.
ColorComponent Property
Gets or sets the color component represented by the slider.
public Avalonia.Controls.ColorComponent ColorComponent { get; set; }
ColorModel Property
Gets or sets the active color model used by the slider.
public Avalonia.Controls.ColorModel ColorModel { get; set; }
HsvColor Property
Gets or sets the currently selected color in the HSV color model.
public Avalonia.Media.HsvColor HsvColor { get; set; }
Remarks
Use this property instead of Avalonia.Controls.Primitives.ColorSlider.Color when in Avalonia.Controls.ColorModel.Hsva to avoid loss of precision and color drifting.
IsAlphaVisible Property
Gets or sets a value indicating whether the alpha component is visible and rendered. When false, this ensures that the gradient is always visible and never transparent regardless of the actual color. This property is ignored when the alpha component itself is being displayed.
public bool IsAlphaVisible { get; set; }
Remarks
Setting to false means the alpha component is always forced to maximum for components other than Avalonia.Controls.Primitives.ColorSlider.ColorComponent during rendering. This doesn't change the value of the alpha component in the color – it is only for display.
IsPerceptive Property
Gets or sets a value indicating whether the slider adapts rendering to improve user-perception over exactness.
public bool IsPerceptive { get; set; }
Remarks
When true in the HSVA color model, this ensures that the gradient is always visible and never washed out regardless of the actual color. When true in the RGBA color model, this ensures the gradient always appears as red, green or blue.
For example, with Hue in the HSVA color model, the Saturation and Value components are always forced to maximum values during rendering. In the RGBA color model, all components other than Avalonia.Controls.Primitives.ColorSlider.ColorComponent are forced to minimum values during rendering.
Note this property will only adjust components other than Avalonia.Controls.Primitives.ColorSlider.ColorComponent during rendering. This also doesn't change the values of any components in the actual color – it is only for display.
IsRoundingEnabled Property
Gets or sets a value indicating whether rounding of color component values is enabled.
public bool IsRoundingEnabled { get; set; }
Remarks
This is applicable for the HSV color model only. The Avalonia.Media.HsvColor struct uses double values while the Avalonia.Media.Color struct uses byte. Only double types need rounding.
