Current Behavior: The Linear Gradient produces a blank image
Expected Behavior: The Linear gradient should produce an image similar to
public CIImage LinearGradient()
var point0 = new CIVector(100, 0); // Default [0 0]
var point1 = new CIVector(0, 100); // Default [200 200]
var inputColor0 = new CIColor(new CGColor(0, 0, 255F)); // Blue
var inputColor1 = new CIColor(new CGColor(255F, 0, 0)); // Red
var linearGrad = new CILinearGradient()
Point0 = point0,
Point1 = point1,
Color0 = inputColor0,
Color1 = inputColor1
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.
