BOOL GpiQueryModelTransformMatrix(hps, cElements, pmatlf)
HPS hps;             /* presentation-space handle                      */
LONG cElements;      /* number of elements                             */
PMATRIXLF pmatlf;    /* address of structure for transformation matrix */
 
The GpiQueryModelTransformMatrix function retrieves the matrix for the
current model transformation. The function cannot be used in an open segment
when the drawing mode is DM_RETAIN.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
hps        Identifies the presentation space.
 
cElements  Specifies the number of elements of the matrix to retrieve. It
           must be an integer in the range 0 through 9.
 
pmatlf     Points to the MATRIXLF structure the receives the model
           transformation matrix.
 
Return Value
 
The return value is GPI_OK if the function is successful or GPI_ERROR if an
error occurred.
 
Errors
 
Use the WinGetLastError function to retrieve the error value, which may be
one of the following:
 
     PMERR_INV_HPS
     PMERR_INV_IN_RETAIN_MODE
     PMERR_INV_LENGTH_OR_COUNT
     PMERR_PS_BUSY
