请高手帮我看一下，能不能帮我把这段代码改成JAVA，主要是指针不知道，谢谢！

void Gettexturefun(CImage * image,double *xf)
{
if (image->IsNull()) return;
int i,j;
int nWidth = image->GetWidth();
int nHeight = image->GetHeight();
int k;
k=0;
int **source = new int *[nWidth*2];
for (i = 0;i<nWidth*2;i++)
source[i] = new int [nHeight*2];

for (i = 0;i<nWidth*2;i++)
for ( j =0;j<nHeight*2;j++)
{
source[i][j]= 0;
}
double a[101][101];
for (i=0;i<101;i++)
for (j = 0;j<101;j++)
{ a[i][j] = 0;
}
for (i = 1; i< nWidth-1; i++){
for (j = 1; j < nHeight-1; j++){
int rr = 0, gg = 0, bb = 0;

COLORREF clr = image->GetPixel( i, j);

// image->SetPixel(i-1,j-1,RGB(rr,gg,bb));

}
}
for (i=0;i<50;i++)
for (j=0;j<50;j++)
{ if (i==j)
{a[i][j] = PXY(i,j,source,nWidth,nHeight);}

delete []source[i];
delete []source;
