示例1: DrawVerticalStringFromBottomUp
public void DrawVerticalStringFromBottomUp(PaintEventArgs e)
{
// Create the string to draw on the form.
string text = "Can you read this?";
// Create a GraphicsPath.
System.Drawing.Drawing2D.GraphicsPath path =
new System.Drawing.Drawing2D.GraphicsPath();
// Add the string to the path; declare the font, font style, size, and
// vertical format for the string.
path.AddString(text, this.Font.FontFamily, 1, 15,
new PointF(0.0F, 0.0F),
new StringFormat(StringFormatFlags.DirectionVertical));
// Declare a matrix that will be used to rotate the text.
System.Drawing.Drawing2D.Matrix rotateMatrix =
new System.Drawing.Drawing2D.Matrix();
// Set the rotation angle and starting point for the text.
rotateMatrix.RotateAt(180.0F, new PointF(10.0F, 100.0F));
// Transform the text with the matrix.
path.Transform(rotateMatrix);
// Set the SmoothingMode to high quality for best readability.
e.Graphics.SmoothingMode =
System.Drawing.Drawing2D.SmoothingMode.HighQuality;
// Fill in the path to draw the string.
e.Graphics.FillPath(Brushes.Red, path);
// Dispose of the path.
path.Dispose();
}示例2: RotateAtExample
public void RotateAtExample(PaintEventArgs e)
{
Pen myPen = new Pen(Color.Blue, 1);
Pen myPen2 = new Pen(Color.Red, 1);
PointF rotatePoint = new PointF(150.0f, 50.0f);
// Draw the rectangle to the screen before applying the
// transform.
e.Graphics.DrawRectangle(myPen, 150, 50, 200, 100);
// Create a matrix and rotate it 45 degrees.
Matrix myMatrix = new Matrix();
myMatrix.RotateAt(45, rotatePoint, MatrixOrder.Append);
// Draw the rectangle to the screen again after applying the
// transform.
e.Graphics.Transform = myMatrix;
e.Graphics.DrawRectangle(myPen2, 150, 50, 200, 100);
