[Chromium-users] How to enable edge blending in chromium 1 .9 under windows

[<sso...@12...>]

Hi all
I am building a tile-display system under windows xp with chromium. Everything is ok except the edge blending.
According to the doc, I had added
nodes[1].Conf("overlap_blending", "knockout")
in the crserver config but it doesn't work.
Anyone knows how to enable it??
thanks
 
 
Below is the conf file i used:
 
# Chromium configuration produced by configtool.py
import string
import sys
sys.path.append( "../server" )
from mothership import *
MOTHERSHIP_OPTIONS = [
 ("MTU", 500000),
 ("auto_start", 0),
 ("auto_start_apps", 0),
 ("autostart_branches", 0),
 ("autostart_max_nodes_per_thread", 1),
]
DEFAULT_APP = ""
AUTO_START_SERVERS = 0
AUTO_START_APPS = 0
# Look for autostart option
for (name, value) in MOTHERSHIP_OPTIONS:
 if name == "auto_start":
  AUTO_START_SERVERS = value
 elif name == "auto_start_apps":
  AUTO_START_APPS = value
# Get program name
if len(sys.argv) == 1:
 pass
elif len(sys.argv) == 2:
 DEFAULT_APP = sys.argv[1]
else:
 print "Usage: %s <program>" % sys.argv[0] 
 sys.exit(-1)
if DEFAULT_APP == "":
 print "No program to run!"
 sys.exit(-1)
