knobmake

create horizontal knob frames with cairo

example

build with:

gcc -g knob_make.c -lm pkg-config --cflags --libs cairo -o knobmake

gcc -g knob_view.c -lX11 pkg-config --cflags --libs cairo -o knobview

then run, for example:

./knobmake 150 101

To create a new knob, you need to edit the source of knob_make.c,
