Auke van Leeuwen ask about transparency last week.
Auke, please try the following:
edit src/rrd_gfx.c line 708 so that it reads ...RGBA in stead of ...RGB.
You may also need to alter line 503: bytes per pixel = 4
Don't forget to actually make the background transparent or
else you will still have a solid color!
--color CANVAS#FFFFFF80 \
--color BACK#FFFFFF80 \
Warning: It has been a while since I looked at the code. Normally
you get exactly 0% guaranty that it works, now even less :)
Please let us know if this helps.
