本文整理汇总了C#中CGGradient类的典型用法代码示例。如果您正苦于以下问题：C#CGGradient类的具体用法？C#CGGradient怎么用？C#CGGradient使用的例子？这里精选的类代码示例或许可以为您提供帮助。 示例1:Draw //GeneratedwithPaintCode2.2 publicoverridevoidDraw(CGRectrect) { base.Draw(rect); //GeneralDeclarations varcolorSpace=CGColorSpace.CreateDeviceRGB(); varcontext=UIGraphics.GetCurrentContext(); //ColorDeclarations vardarkBlue=UIColor.FromRGBA(0.053f,0.123f,0.198f,1.000f); varlightBlue=UIColor.FromRGBA(0.191f,0.619f,0.845f,1.000f); //GradientDeclarations varbackgroundGradientColors=newCGColor[]{lightBlue.CGColor,darkBlue.CGColor}; varbackgroundGradientLocations=newnfloat[]{0.0f,1.0f}; varbackgroundGradient=newCGGradient(colorSpace,backgroundGradientColors,backgroundGradientLocations); //RectangleDrawing varrectangleRect=newCGRect(rect.GetMinX()+(float)Math.Floor(rect.Width*-0.12917f+0.5f),rect.GetMinY()+(float)Math.Floor(rect.Height*0.00000f+0.5f),(float)Math.Floor(rect.Width*1.00000f+0.5f)-(float)Math.Floor(rect.Width*-0.12917f+0.5f),(float)Math.Floor(rect.Height*1.00000f+0.5f)-(float)Math.Floor(rect.Height*0.00000f+0.5f)); varrectanglePath=UIBezierPath.FromRect(rectangleRect); context.SaveState(); rectanglePath.AddClip(); context.DrawLinearGradient(backgroundGradient, newPointF((float)rectangleRect.GetMidX(),(float)rectangleRect.GetMinY()), newPointF((float)rectangleRect.GetMidX(),(float)rectangleRect.GetMaxY()), 0); context.RestoreState(); }
