arraycopy

I am try to manipulate an 2D array, into a 1D array, but must also flip the 2D array, so that the last element of the 2D array is now the first element of the 1D array.
Sorta like a nested loop, where:
1D[0] = 2D[5][10];
1D[50] = 2D[0][0];
The arrays that I have to flip are used to draw an image using MemoryImageSource, so they are quite large(512x1024).
Is it posible to use arraycopy to get better performance in this situtation.

I think arrayCopy() is a native call and if I am right, it should be faster than a loop.

Arraycopy is faster than a loop, but how would you use arraycopy to convert a 2d array, into a 1d array, where the last element of the 2d array is the first elemet of the 1d array.

For what you want to do, it sounds like a loop is your best bet.
