Help needed with C stuff again

Hi everyone.
I have a simple 'C' Morfit example I am trying to convert to Euphoria.
The example in C has the following....
BYTE *pixels=3DMorfit_bitmap_get_memory(bitmap_handle);
WORD *palette=3DMorfit_bitmap_get_palette(bitmap_handle);
The returns are pointers to memory that hold a bitmap and
a palette.
Also the following....
WORD color16=3Dpalette[pixels[y*width+x]];
The line above has me a bit stumped. It seems to be using one pointer
as an index to another? It is in a pair of nested for loops, =
incrementing
x and y.
My wrap of the two functions just returns the pointers (the same as with =
C)
The result is passed to the following function....
Morfit_utilities_rgb16_to_rgb24(color16, (BYTE *)&red, (BYTE *)&green, =
(BYTE *)&blue);
Any help with wrapping that line would be greatly appreciated!
Thanks
Mark
