Hi Gerd, > Bicubic expects grid [-1,0,1,2] X [-1,0,1,2] > fillArray uses [0,1,2,3]X[0,1,2,3]
That's the reason for "-1" in following code: h = rdr.ele(xLeft + x - 1, yBottom + y - 1); eleArray[x][y] = h; I have corrected some errors, will post a new patch soon. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
