GradientColorPicker Control for Windows Forms

This is control for Windows Forms, which allows to select colors to create gradients.

Install

To install GradientColorPicker control, run the following command in the Package Manager Console:

Install-Package GradientColorPicker

How to use

Install the GradientColorPicker package in your Windows Forms project.

Or download an archive file containing binary assemblies, unpack it and add to your project a reference to the assembly of the version of .NET Framework that you are using.

Now you can create an instance of the GradientColorPicker and add to the form:

// create a new instance of GradientColorPicker
var gradientColorPicker = new GradientColorPicker();

// for example, set the minimum number of items (colors)
gradientColorPicker.MinimumColorCount = 4;

// for example, randomize the postion and color of the items
gradientColorPicker1.Randomize(true, true);

// add the GradientColorPicker to the form
Controls.Add(gradientColorPicker);

// use the DrawLinearGradientToImage method to drawing linear gradient image
// for example, draw a gradient in the background image of the form

// create image 
BackgroundImage = new Bitmap(ClientSize.Width, ClientSize.Height);
// draw a linear gradient
gradientColorPicker1.DrawLinearGradientToImage(BackgroundImage);

// or DrawRadialGradientToImage method  to drawing radial gradient image

// we need to specify a central point
var centerPoint = new PointF(ClientSize.Width / 2, ClientSize.Height / 2);
// draw a radial gradient
gradientColorPicker1.DrawRadialGradientToImage(BackgroundImage, ClientRectangle, centerPoint);

If you can not find the control on the toolbox in designer mode, you need to add GradientColorPicker to the toolbox:

1. Right-click on toolbox.
2. Select "Choose Items".
3. Browse the GradientColorPicker assembly on your computer.
4. Add the item.
5. Enjoy!
