Single-Color Texture

Sometimes it can be handy to create a quick texture in a solid color (i.e. for drawing rectangles). This class will do it on the fly:

namespace Utilities
{
    using System;
    using Microsoft.Xna.Framework;
    using Microsoft.Xna.Framework.Graphics;
 
    /// <summary>
    /// Creates single color textures (i.e. for drawing rectangles).
    /// </summary>
    class ColorTexture
    {
        /// <summary>
        /// Creates a 1x1 pixel black texture.
        /// </summary>
        /// <param name="graphicsDevice">The graphics device to use.</param>
        /// <returns>The newly created texture.</returns>
        public static Texture2D Create(GraphicsDevice graphicsDevice)
        {
            return Create(graphicsDevice, 1, 1, new Color());
        }
 
        /// <summary>
        /// Creates a 1x1 pixel texture of the specified color.
        /// </summary>
        /// <param name="graphicsDevice">The graphics device to use.</param>
        /// <param name="color">The color to set the texture to.</param>
        /// <returns>The newly created texture.</returns>
        public static Texture2D Create(GraphicsDevice graphicsDevice, Color color)
        {
            return Create(graphicsDevice, 1, 1, color);
        }
 
        /// <summary>
        /// Creates a texture of the specified color.
        /// </summary>
        /// <param name="graphicsDevice">The graphics device to use.</param>
        /// <param name="width">The width of the texture.</param>
        /// <param name="height">The height of the texture.</param>
        /// <param name="color">The color to set the texture to.</param>
        /// <returns>The newly created texture.</returns>
        public static Texture2D Create(GraphicsDevice graphicsDevice, int width, int height, Color color)
        {
            // create the rectangle texture without colors
            Texture2D texture = new Texture2D(
                graphicsDevice, 
                width, 
                height, 
                1, 
                TextureUsage.None,
                SurfaceFormat.Color);
 
            // Create a color array for the pixels
            Color[] colors = new Color[width * height];
            for (int i = 0; i < colors.Length; i++)
            {
                colors[i] = new Color(color.ToVector3());
            }
 
            // Set the color data for the texture
            texture.SetData(colors);
 
            return texture;
        }
    }
