Memory usage of images in WPF
===

This is a comprehension question.

When I have an jpeg image (A4, 96DPI, 24 bits per pixel) which takes up 200KB at 90% quality level on the disk and I load it in WPF (e.g. with XAML).

    <Image Source="MyJpeg.jpg"></Image>

WPF would have memory consumption for the image of not (only) 200KB but at least 8.27 x 11.69 X 96² X 24 / 8 / 1024 = 2610.26KB, right?

with:

    Size of A4 =  8.27 inch  x 11.69 inch 
    Pixels in the whole picture = [Size of A4] x 96²
    Bits for the whole picture = [Pixels in the whole picture] x 24
    Bytes for the whole picture = [Bits for the whole picture] / 8
