What I would like to get is an option for mkgamp, that will allow for testing quality of all these versions of interpolation. For now we have bilinear, bicubic and bicubic spline. This all could be included in code and selected by user. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
