ConicalGradient QML Type

This property defines the starting angle where the color at the gradient position of 0.0 is rendered. Colors at larger position values are rendered into larger angle values and blended seamlessly. Angle values increase clockwise.

This property allows the effect output pixels to be cached in order to improve the rendering performance.

Every time the source or effect properties are changed, the pixels in the cache must be updated. Memory consumption is increased, because an extra buffer of memory is required for storing the effect output.

It is recommended to disable the cache when the source or the effect properties are animated.

By default, the property is set to false.

A gradient is defined by two or more colors, which are blended seamlessly. The colors are specified as a set of GradientStop child items, each of which defines a position on the gradient (from 0.0 to 1.0), and a color. The position of each GradientStop is defined by the position property. The color is defined by the color property.

 Gradient {
   GradientStop {
      position: 0.000
      color: Qt.rgba(1, 0, 0, 1)
   }
   GradientStop {
      position: 0.167
      color: Qt.rgba(1, 1, 0, 1)
   }
   GradientStop {
      position: 0.333
      color: Qt.rgba(0, 1, 0, 1)
   }
   GradientStop {
      position: 0.500
      color: Qt.rgba(0, 1, 1, 1)
   }
   GradientStop {
      position: 0.667
      color: Qt.rgba(0, 0, 1, 1)
   }
   GradientStop {
      position: 0.833
      color: Qt.rgba(1, 0, 1, 1)
   }
   GradientStop {
      position: 1.000
      color: Qt.rgba(1, 0, 0, 1)
   }
 }

 Gradient {
   GradientStop {
      position: 0.0
      color: "#F0F0F0"
   }
   GradientStop {
      position: 0.5
      color: "#000000"
   }
   GradientStop {
      position: 1.0
      color: "#F0F0F0"
   }
 }

 Gradient {
   GradientStop {
      position: 0.0
      color: "#00000000"
   }
   GradientStop {
     position: 1.0
     color: "#FF000000"
   }
 }

The horizontalOffset and verticalOffset properties define the offset in pixels for the center point of the gradient compared to the item center.

The value ranges from -inf to inf. By default, the properties are set to 0.

This property defines the item that is going to be filled with gradient. Source item gets rendered into an intermediate pixel buffer and the alpha values from the result are used to determine the gradient's pixels visibility in the display. The default value for source is undefined and in that case whole effect area is filled with gradient.

The horizontalOffset and verticalOffset properties define the offset in pixels for the center point of the gradient compared to the item center.

The value ranges from -inf to inf. By default, the properties are set to 0.
