Overloads
| SetFillColor(CGColor) |
Sets the fill color to the specified CGColor. |
| SetFillColor(nfloat[]) |
Sets the fill color. SetFillColorSpace(CGColorSpace) must be called prior. |
| SetFillColor(nfloat, nfloat) |
Sets the fill color to a gray level, in the range 0 (black) to 1 (white). |
| SetFillColor(nfloat, nfloat, nfloat, nfloat) |
Sets the fill color to the specified RGBA values. |
| SetFillColor(nfloat, nfloat, nfloat, nfloat, nfloat) |
Sets the fill color using CMYK color-space components, plus an alpha value. |
SetFillColor(CGColor)
SetFillColor(nfloat[])
Sets the fill color. SetFillColorSpace(CGColorSpace) must be called prior.
public void SetFillColor (nfloat[] components);member this.SetFillColor : nfloat[] -> unitParameters
- components
- nfloat[]
An array of components, specific to the currently selected colorspace
Remarks
Sets the fill color to the values specified in the components array. The number of elements in this array must be equal to the number of components in the current colorspace plus an additional element for the alpha value. Developers must previously set the colorspace on the context using SetFillColorSpace(CGColorSpace), otherwise the results of calling this method are unspecified.
