Ah well, create a new bitmap in memory with the required size, blit from the source image to the target image the part you want to cut out and then save this new bitmap.
So something like this:

HDC pDC=::GetDC(0);
HDC TmpDC=CreateCompatibleDC(pDC);
CImage _image;
_image.Load(_T("//read.tif"));
int width=_image.GetWidth();
int height=_image.GetHeight();
HGDIOBJ TmpObj2 = SelectObject(TmpDC,(HGDIOBJ)(HBITMAP)_image);			

int newWidth  = width/2;
int newHeight = height/2;
HDC NewDC = CreateCompatibleDC(TmpDC);
HBITMAP NewBitmap = CreateCompatibleBitmap(TmpDC, newWidth, newHeight);
HGDIOBJ NewTmpObj = SelectObject(NewDC, NewBitmap);

BitBlt(NewDC, 0, 0, newWidth, newHeight, TmpDC, 0, 0, SRCCOPY);

SelectObject(NewDC, NewTmpObj);
DeleteDC(NewDC);

SelectObject(TmpDC,TmpObj2);
::ReleaseDC(NULL,pDC);

CImage newImage;
newImage.Attach(NewBitmap);
newImage.Save( _T("D:\\newy.jpg"), Gdiplus::ImageFormatJPEG);
DeleteObject(NewBitmap); //Is this needed, will CImage destroy the bitmap or not?

I am not saying this code works or if it compiles at all, but it can be a starting point for you to get the idea, good luck.
