You can do an $ apt-get source navit then you should get the source and the build directory. Then debian/rules contains the configuration # scale all gui icons DEB_CONFIGURE_EXTRA_FLAGS += --enable-svg2png-scaling="16 24 32 48 64" \ --enable-svg2png-scaling-flag="16 24 32" \ --enable-svg2png-scaling-nav="16 32 48 64" I never changed that. Can you explain what the three parameters are doing and what settings you are recommending? Thanks.
