示例1: ChangePageScaleAndTranslateTransform
private void ChangePageScaleAndTranslateTransform(PaintEventArgs e)
{
// Create a rectangle.
Rectangle rectangle1 = new Rectangle(20, 20, 50, 100);
// Draw its outline.
e.Graphics.DrawRectangle(Pens.SlateBlue, rectangle1);
// Change the page scale.
e.Graphics.PageScale = 2.0F;
// Call TranslateTransform to change the origin of the
// Graphics object.
e.Graphics.TranslateTransform(10.0F, 10.0F);
// Draw the rectangle again.
e.Graphics.DrawRectangle(Pens.Tomato, rectangle1);
// Set the page scale and origin back to their original values.
e.Graphics.PageScale = 1.0F;
e.Graphics.ResetTransform();
SolidBrush transparentBrush = new SolidBrush(Color.FromArgb(50,
Color.Yellow));
// Create a new rectangle with the coordinates you expect
// after setting PageScale and calling TranslateTransform:
// x = (10 + 20) * 2
// y = (10 + 20) * 2
// Width = 50 * 2
// Length = 100 * 2
Rectangle newRectangle = new Rectangle(60, 60, 100, 200);
// Fill in the rectangle with a semi-transparent color.
e.Graphics.FillRectangle(transparentBrush, newRectangle);
