部分源代码如下：
using namespace std;
fitsfile fptr;
fitsfile *fptr1;
int status;
int existkeys, morekeys, keynum;
int bitpix;
long ii,jj;
int datatype=0;
long *fpixel=NULL;
void *nulval=NULL;
unsigned char *nwarray=NULL;
int *anynul=NULL;
LONGLONG nelem;
LONGLONG naxis1=0;
LONGLONG naxis2=0;
char comment[FLEN_COMMENT];
ffopen(&fptr, "R2512137P.fit", 1, &status);
ffgkyjj(fptr, "NAXIS1", &naxis1, comment, &status);
ffgkyjj(fptr, "NAXIS2", &naxis2, comment, &status);
nelem=(LONGLONG)naxis1(LONGLONG)naxis2;
ffgpxv(fptr, datatype, fpixel, nelem, nulval, nwarray, anynul, &status);
for (ii = 0; ii < naxis2; ii++)
for (jj = 0; jj < naxis1; jj++)
{
hdc->SetPixel(ii,jj,RGB(nwarray[(ii-1)*(long)naxis1+jj],nwarray[(ii-1)*(long)naxis1+jj],nwarray[(ii-1)*(long)naxis1+jj]));
}
出现如题问题，不知道是何原因，求大神指教！
