Detailed Description

Resource class.

Library: display

The IlvRadialGradientGeometry class enables you specify geometrical properties dedicated to radial gradients. A radial gradient geometry is defined by a start and an end circle. The centers of the 2 circles must be contained within the IlvGradientPattern area defined by its width and height. The abscissas of these centers must be set between 0 and IlvPattern::width. The ordinates of these centers must be set between 0 and IlvPattern::height. The start circle must be contained within the end circle, otherwise the rendering becomes unpredictable, depending on whether you are drawing using Cairo or GDI+.
