init(colors:atLocations:colorSpace:)

Initializes a newly allocated gradient object with the specified colors, color locations, and color space.

Declaration

init?(colors colorArray: [NSColor], atLocations locations: UnsafePointer<CGFloat>?, colorSpace: NSColorSpace)

Parameters

  • colorArray:

    An array of NSColor objects representing the colors in the gradient.

  • locations:

    An array of CGFloat values containing the location for each color in the gradient. Each value must be in the range 0.0 to 1.0. There must be the same number of locations as are colors in the colorArray parameter.

  • colorSpace:

    The color space to use for the gradient.

Return Value

The initialized NSGradient object.

Discussion

This method is the designated initializer of NSGradient. The colors in the colorArray parameter are converted to the specified color space if they are not already in that color space.

Typically, at least one color should have a location of 0.0 and one should have a location of 1.0. If these locations are not specified, the color at the closest color stop is used to fill the gap.
