Thread: Converting JNX to raster IMG

For device with JNX support the pure JNX format is more convenient. But some device especially for marine mode do not support JNX at first and do not show properly modern vector topo map with content prescribed in TYP section. For such devices this program is only salvage.
But you can make separate map for each level on that you want to see raster and then combine it with gmapTool or MapSource. Also experiments with TRE parameters is welcome too...
