Graphics平移缩放旋转(转载)+点睛

点睛：可以进行多次旋转和平移，也就是平移以后再平移，旋转以后再旋转，有时候一次达不到要求，如果你想一次调整完美的话很麻烦，所以最好多次，上代码

 private void btnTranslate_Click(object sender, EventArgs e)

        {

            Graphics graphics = this.CreateGraphics();

            // 红色笔

            Pen pen = new Pen(Color.Red, );

            Rectangle rect = new Rectangle(, , , );

            // 用红色笔画矩形

            graphics.DrawRectangle(pen, rect);

            // 向左平移100向下平移50

            graphics.TranslateTransform(, );

            // 蓝色笔

            pen.Color = Color.Blue;

            // 用蓝色笔重新画平移之后的矩形

            graphics.DrawRectangle(pen, rect);

            graphics.Dispose();

            pen.Dispose();

        }

        private void btnScale_Click(object sender, EventArgs e)

        {

            Graphics graphics = this.CreateGraphics();

            // 红色笔

            Pen pen = new Pen(Color.Red, );

            Rectangle rect = new Rectangle(, , , );

            // 用红色笔画矩形

            graphics.DrawRectangle(pen, rect);

            graphics.ScaleTransform(0.5f, );

            // 蓝色笔

            pen.Color = Color.Blue;

            // 用蓝色笔重新画平移之后的矩形

            graphics.DrawRectangle(pen, rect);

            graphics.Dispose();

            pen.Dispose();

        }

        private void btnTranslate1_Click(object sender, EventArgs e)

        {

            Graphics graphics = this.CreateGraphics();

            // 红色笔

            Pen pen = new Pen(Color.Red, );

            Rectangle rect = new Rectangle(, , , );

            // 用红色笔画矩形

            graphics.DrawRectangle(pen, rect);

            graphics.TranslateTransform( , );

            graphics.RotateTransform();

            // 蓝色笔

            pen.Color = Color.Blue;

            // 用蓝色笔重新画平移之后的矩形

            graphics.DrawRectangle(pen, rect);

            graphics.Dispose();

            pen.Dispose();

        }
