Image::RotateFlip Method

This method rotates, flips, or rotates and flips the Image.

Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public:
void RotateFlip(
	RotateFlipType rotateFlipType
)

Parameters

rotateFlipType
Type: System.Drawing::RotateFlipType

A RotateFlipType member that specifies the type of rotation and flip to apply to the image.

If you wish to draw on an image once it has been rotated, you should always retrieve a new graphics object from the image, otherwise an exception could occur.

The following code example demonstrates how to set the RotateFlip property of an Image and the RotateFlipType enumeration.

This example is designed to be used with a Windows Form that contains a PictureBox named PictureBox1 and a button named Button1. Paste the code into a form, call InitializeBitmap from the form's constructor, and associate Button1_Click with the button's Click event. Ensure the file path to the bitmap is valid on your system.

Bitmap^ bitmap1;
void InitializeBitmap()
{
   try
   {
      bitmap1 = dynamic_cast<Bitmap^>(Bitmap::FromFile( "C:\\Documents and Settings\\" 
      "All Users\\Documents\\My Music\\music.bmp" ));
      PictureBox1->SizeMode = PictureBoxSizeMode::AutoSize;
      PictureBox1->Image = bitmap1;
   }
   catch ( System::IO::FileNotFoundException^ ) 
   {
      MessageBox::Show( "There was an error." 
      "Check the path to the bitmap." );
   }

}

void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   if ( bitmap1 != nullptr )
   {
      bitmap1->RotateFlip( RotateFlipType::Rotate180FlipY );
      PictureBox1->Image = bitmap1;
   }
}
