Current Behavior: Using the Gaussian Gradient produces a Blank image.
Expected Behavior: The Gaussian Gradient should produce and image similar to https://developer.apple.com/library/mac/documentation/graphicsimaging/reference/CoreImageFilterReference/Art/CIGaussianGradient.gif
public CIImage GaussianGradient ()
var centerVector = new CIVector (100, 100); // Default is [150 150]
var color1 = new CIColor (new CGColor (255F, 255F, 255F));
var color0 = new CIColor (new CGColor (0, 0, 0));
var gaussGradient = new CIGaussianGradient ()
Center = centerVector,
Color0 = color0,
Color1 = color1,
Radius = 500F // Default is 300
This was a bug in the sample.
It turns out that for filters that generate images without an input image there
is no region defined for the filter, so we must manually call Crop on the
resulting image to render.
