    My comment:
    More functionality like printing and saving the scaled image to another file can be added to this class in a short time from code examples already included in this reference.

    The native FoxPro function LoadPicture returns valid bitmap handle when applied to bitmap files (GIF and JPEG files also):

            obj = LoadPicture("mybitmap.bmp")
            ? "Bitmap handle:", obj.handle


    Actually LoadPicture() returns an object with properties Handle, Height, hPal, Type,and Width.

    Also it has a single method Render called with parameters (VB syntax)
            hdc As Long, x As Long, y As Long,
            cx As Long, cy As Long,
            xSrc As OLE_XPOS_HIMETRIC, ySrc As OLE_YPOS_HIMETRIC,
            cxSrc As OLE_XSIZE_HIMETRIC, cySrc As OLE_YSIZE_HIMETRIC,
            prcWBounds As Any
