Detailed Description

An abstract class representing the gradient fill of the Shape object.

It contains the information about the gradient colors and their arrangement inside the gradient bounds. The gradients bounds are defined in the LinearGradient or RadialGradient class, depending on the type of the gradient to be used. It specifies the gradient behavior in case the area defined by the gradient bounds is smaller than the area to be filled.

Member Function Documentation

colorStops() [1/2]

Result colorStops ( const ColorStop *  colorStops, uint32_t  cnt  )

noexcept

Sets the parameters of the colors of the gradient and their position.

Parameters

[in]	colorStops	An array of ColorStop data structure.
[in]	cnt	The count of the colorStops array equal to the colors number used in the gradient.

Returns

Result::Success when succeed.

colorStops() [2/2]

uint32_t colorStops ( const ColorStop **  colorStops ) const

noexcept

Gets the parameters of the colors of the gradient, their position and number.

Parameters

[in]

colorStops

A pointer to the memory location, where the array of the gradient's ColorStop is stored.

Returns

The number of colors used in the gradient. This value corresponds to the length of the colorStops array.

duplicate()

Fill* duplicate ( ) const

noexcept

Creates a copy of the Fill object.

Return a newly created Fill object with the properties copied from the original.

Returns

A copied Fill object when succeed, nullptr otherwise.

spread() [1/2]

Result spread ( FillSpread  s )

noexcept

Sets the FillSpread value, which specifies how to fill the area outside the gradient bounds.

Parameters

[in]

s

The FillSpread value.

Returns

Result::Success when succeed.

spread() [2/2]

FillSpread spread ( ) const

noexcept

Gets the FillSpread value of the fill.

Returns

The FillSpread value of this Fill.
