使用gpx航跡檔slake.gpx
輸出記錄檔r2map2.log
gpx x67diff(3296.772671,1791.368684)
width=3296 height=1791
使用圖資底檔slake.png
水平及垂直縮放倍率(rw,rh)=(1.500000,1.500000)
底圖寬高為 width=1581 height=2211
縮放後寬高為 width=2371.500000 height=3316.500000
gpx檔推算的原點座標(ox,oy)=(323000,2699000)
圖資底圖左上角原點座標(ox,oy)=(324000,2701000)
輸出航跡疊圖r2map2.jpg 成功！
