There is pngtogd utility in gd package somewhere. I did not remember exactly, however, I did use it and it works as its name implies - converts png images to gd. (Maybe it is spelled png2gd, I am not sure). > rrdtool graph /home/herman/public_html/stats/misc_test.gd --start -1d \ > --title "Misc. $arg" \ > -B /home/herman/public_html/stats/misc_test.gd \ > DEF:cs=vmstat.rrd:cs:AVERAGE \ > DEF:intr=vmstat.rrd:int:AVERAGE \ > CDEF:allusers=cs,intr,+ \ > CDEF:wrongdata=allusers,UN,INF,UNKN,IF \ > AREA:wrongdata#FF0000:"Wrong data" \ > AREA:cs#ff3377:"(Context switches/s)" \ > LINE2:intr#0000ff:"Intr/s" > I see no reason for refusing to work correctly, anyway, using the same file name for both output image file and background source image file looks a bit strange to me, even if this is (maybe) not the problem itself. > > after 2 minutes the program segfaults. > > [EMAIL PROTECTED]:/home/herman/stats# sh test.sh > test.sh: line 11: 7826 Segmentation fault rrdtool graph > /home/herman/public_html/stats/misc_test.gd --start -1d --title "Misc. > $arg" -B /home/herman/public_html/stats/misc_test.gd > DEF:cs=vmstat.rrd:cs:AVERAGE DEF:intr=vmstat.rrd:int:AVERAGE > CDEF:allusers=cs,intr,+ CDEF:wrongdata=allusers,UN,INF,UNKN,IF > AREA:wrongdata#FF0000:"Wrong data" AREA:cs#ff3377:"(Context switches/s)" > LINE2:intr#0000ff:"Intr/s" > Could You try to look where rrdtool segfaults? Does it dump core? Using 'gdb rrdtool core' and then issuing command bt may give us an idea, where program crashes, if compiled with symbols. With so sparse information available we can only use crystal ball to try to find the problem :) > > I can't get the overlay and background pictures to work. > > so I have 2 questions. > > 1. How do i convert ANY image to gd format. > 2. Why does it segfault over and over. and how can i fix this ? I think both are partially answered above. Anyway, it would be usefull to know rrdtool version, system used (version too maybe), try to do something more to make it easier for both you and us to find the problem and fix it.
