C# Load JPG file, extract BitmapImage
48,586
Try this:
public void Load(string fileName)
{
using(Stream BitmapStream = System.IO.File.Open(fileName,System.IO.FileMode.Open ))
{
Image img = Image.FromStream(BitmapStream);
mBitmap=new Bitmap(img);
//...do whatever
}
}
Or you can just do this (source):
Bitmap myBmp = Bitmap.FromFile("path here");

I am trying to extract a BitmapImage from a JPG. This is the code I have:
FileStream fIn = new FileStream(sourceFileName, FileMode.Open); // source JPG Bitmap dImg = new Bitmap(fIn); MemoryStream ms = new MemoryStream(); dImg.Save(ms, ImageFormat.Jpeg); image = new BitmapImage(); image.BeginInit(); image.StreamSource = new MemoryStream(ms.ToArray()); image.EndInit(); ms.Close();
image comes back with a 0 × 0 image, which of course means it didn't work. How do I do this?

IamIC about 12 yearsI found my mistake: I need to use Image, not BitmapImage. I knew it didn't need to be complicated! This is the working code: Image image = Image.FromFile(sourceFileName, true);

IamIC about 12 yearsBoy is this complicated initially! Image, BitmapImage, ImageSource, JpegImageDecoder etc. etc.
