or,

img=CreateImage(TerrainSize(t),TerrainSize(t))
SetBuffer ImageBuffer(img)
LockBuffer
For x=0 To TerrainSize(t)-1
	For z=0 To TerrainSize(t)-1
		c=TerrainHeight(t,x,z)*255
		c=(c Shl 16)
		;blitz only uses the red channel for heightmaps, but if you want greys, uncomment the next line
		;c=(c Shl 16)+(c shl 8)+c
		WritePixelFast x,TerrainSize()-z,c
	Next
Next
UnlockBuffer
SetBuffer BackBuffer()


that should work.
