how can i load jpg from file

[user@domain.invalid]

Hello
I finally managed to save Bitmap that reprezented my pictureBox to jpg
file, but now how can i load from that file to Bitmap again ?
Bitmap does not have any Load or Open method (like Save...).


Thanx

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,Sys tem.IO.FileMode .Open);
Image imgPhoto = Image.FromStrea m(BitmapStream) ;
BitmapStream.Cl ose();

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