[rrd-users] overlay vs composite

[David O'Brien]

Hi,
How hard would it be to incorporate the ImageMagick "composite" feature into
rrdtool to replace the --overlay function (that I never have been able to 
get to work.)

I have been generating graphs and then running them thru IM'a composite to 
"pretty" them up a bit
and read on the IM pages that they have a C++ API.

Examples:
http://www.naccrraware.net/cluster/totals.php


Files used to create this graph:
cpu.exp  -  gets the info from the server (ssh & expect)
cpu.php  -  parses cpu.exp output into "n::::::" format
cpu.sh   -  updates the rrdtool db
makecpugfx.sh -  generates the graph

cpumask.png  - - PNG mask that I composite onto the image generated by 
makecpugfx.sh

makecpu.sh - initialize the rrd
