Saves barcode as image into a memory buffer (Windows only).
Draws the barcode and saves it using the specified image format to a memory buffer (pass a pointer variable of an arbitrary type as argument). The values of XSize and YSize should be increased, if the barcode is not readable or requires a high printing resolution. The values of XRes and YRes can affect the printing size when printing from graphic- or painting programs (but not when printing from the browser!). The buffer will be allocated on the global heap. Retrieve the buffer size in Bytes with GlobalSize((HGLOBAL)GlobalHandle(buffer)). It is recommended to lock the buffer before reading with pMem = GlobalLock (hMem) and unlock it afterwards (GlobalUnlock(hMem)). When no longer needed the buffer must be released by calling GlobalFree(hMem) (WINDOWSX.h macro).
