使用Brush類繪製圖像

代碼如下:

public partial class TextureBruse : Form
    ...{
        private Image theimage;
        private Image smallimage;

        public TextureBruse()
        ...{
            InitializeComponent();

            SetStyle(ControlStyles.Opaque, true);
            Bounds = new Rectangle(0, 0, 500, 500);
            theimage = new Bitmap("ico.gif");      //Application.StartupPath+@"ico.gif"
            smallimage = new Bitmap(theimage, new Size(theimage.Width, theimage.Height));
        }
        protected override void OnPaint(PaintEventArgs e)
        ...{
            Graphics g = e.Graphics;
            g.FillRectangle(Brushes.White,ClientRectangle);
            
            Brush brush = new TextureBrush(smallimage, new Rectangle(0, 0,smallimage.Width, smallimage.Height));
            //用圖像創建畫筆,來繪制圖像
            g.FillEllipse(brush, new Rectangle(0,200,200,200));
            //用圖像創建剛筆,來繪制圖像
            Pen pen=new Pen(brush,20);
            g.DrawRectangle(pen, new Rectangle(250, 200, 200, 200));
            //用圖像繪製文本
            Font font = new Font("Times New Roman", 40, FontStyle.Bold | FontStyle.Italic);
            g.DrawString("Hello Image !!", font, brush, new Rectangle(0,0,500,font.Height));

            brush.Dispose();
            font.Dispose();
        }
    }
