RadialGradientImage

RadialGradientImage[gcol] returns an image with values radially changing from center to corners based on gradient color gcol.

RadialGradientImage[{pos1,pos2}->gcol] returns an image where the gradient starts at pos1 and ends at pos2.

RadialGradientImage[…,size] returns a radial gradient image of the specified size.

RadialGradientImage[…,size,"type"] gives an image converted to the specified type.

Examples

Create a radial gradient from white to black:

RadialGradientImage[{White, Black}]

Specify the size:

RadialGradientImage[{Red, Blue}, {200, 200}]
