Examples
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 or Load event-handling method 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;
}
}
Bitmap bitmap1;
private void InitializeBitmap()
{
try
{
bitmap1 = (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.");
}
}
private void Button1_Click(System.Object sender, System.EventArgs e)
{
if (bitmap1 != null)
{
bitmap1.RotateFlip(RotateFlipType.Rotate180FlipY);
PictureBox1.Image = bitmap1;
}
}
Dim bitmap1 As Bitmap
Private Sub InitializeBitmap()
Try
bitmap1 = CType(Bitmap.FromFile("C:\Documents and Settings\All Users\" _
& "Documents\My Music\music.bmp"), Bitmap)
PictureBox1.SizeMode = PictureBoxSizeMode.AutoSize
PictureBox1.Image = bitmap1
Catch ex As System.IO.FileNotFoundException
MessageBox.Show("There was an error. Check the path to the bitmap.")
End Try
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
If bitmap1 IsNot Nothing Then
bitmap1.RotateFlip(RotateFlipType.Rotate180FlipY)
PictureBox1.Image = bitmap1
End If
End Sub
Remarks
The image is rotated in a clockwise direction.
