i would guess the problem is this (in CRawDoc::Serialize):

// Hardcoded startup parameters (may be changed for other size raw files).
		int iWidth  = 256; // for lena.raw - you can change for different value
		int iHeight = 256; // for lena.raw - you can change for different value

otherwise, if you want to display an image at a larger size than its native size use StretchBlt() instead of BitBlt()
