How to convert image to byte array

Question

Can anybody suggest how I can convert an image to a byte array and vice versa?

I\'m developing a WPF application and using a stream reader.

Answer 1

Do you only want the pixels or the whole image (including headers) as an byte array?

For pixels: Use the CopyPixels method on Bitmap. Something like:

var bitmap = new BitmapImage(uri);

//Pixel array
byte[] pixels = new byte[width * height * 4]; //account for stride if necessary and whether the image is 32 bit, 16 bit etc.

bitmap.CopyPixels(..size, pixels, fullStride, 0);
