Bitmap does not have any Load or Open method (like Save...).

Hi,

One option is using the constructor to load the file. The Bitmap class
constructor has many overloads and one of it accepts the file name as
parameter.

To load any image you can call:
Image.FromFile(...)

If image if a JPEG then You can cast it to Bitmap.
e.g. Bitmap myJpeg=(Bitmap) Image.FromFile("myJpegPath");

Something like this, this prevents locking the file too long.

public void Load(string asFile) {
//--- Because Image keeps th file locked untill the garbage collector
releases it, we have
// to make it released as soon a possible using this trick.
Stream BitmapStream =
System.IO.File.Open(asFile,System.IO.FileMode.Open );
Image imgPhoto = Image.FromStream(BitmapStream);
BitmapStream.Close();

//--- Now the file is beeing released continue using the contents.
mBitmap=new Bitmap(imgPhoto);
}
