Remarks
DIBStretch() copies a DIB into a destination rectangle of <nWidth> by <nHeight>, stretching or compressing the bitmap by a factor of <r8Zoom> to fit the dimensions of the specified window, <hWnd>. <r8Zoom> can be calculated as <size of the area>/<size of the bitmap>. For example, a value of 2.0 would double the bitmap size, while a value of 0.5 would shrink the DIB to half its normal size.
