I created an Image with this code
OpenFileDialog dlg = new OpenFileDialog();
dlg.FileName = ""; // Default file name
myImage = new Image();
try
{
Nullable<bool> result = dlg.ShowDialog();
if (result == true)
{
string sUri = @dlg.FileName;
Uri src = new Uri(sUri, UriKind.RelativeOrAbsolute);
BitmapImage bmp = new BitmapImage(src);
myImage.Source = bmp;
myImage.Width = 100;
myImage.Height = 100;
}
}
I can zoom in/out on this image
public void Scale(int i, Point center)
{
Matrix m = myImage.RenderTransform.Value;
if (i > 0)
m.ScaleAtPrepend(1.1, 1.1, center.X, center.Y);
else
m.ScaleAtPrepend(1 / 1.1, 1 / 1.1, center.X, center.Y);
myImage.RenderTransform = new MatrixTransform(m);
}
but when I get the ActualWidth or Width or ActualHeight/Height returns the number 100. this means that these changes not applied to origin image (myImage). Now How to apply the changes (zoom or any changes) to origin Image?
Tanx all;
