[magick-users] ImageMagick (Blur) query

[Ravinderjit Singh. Sidhu]

Dear ImageMagick Friends,
 
I need your help  regarding blur effect on text !
 
I am trying  (Blur) in windows platfom on command line:
------------------------------------------------------------------------
-----------
convert -size 2100x1200 xc:white ^
  ( -font  arial  -pointsize 105 -fill rgb(0,0,0)   -draw  " text  100,
100 '1.ImageMagick'" -blur 1,1 ) ^
  ( -font  arial  -pointsize 105 -fill rgb(0,0,0)   -draw  " text  100,
300 '2.ImageMagick'" -blur 0,8 ) ^
  ( -font  arial  -pointsize 105 -fill rgb(0,0,0)   -draw  " text  100,
600 '3.ImageMagick'" -blur 0,8 ) ^
  ( -font  arial  -pointsize 105 -fill rgb(0,0,0)   -draw  " text  100,
900 '4.ImageMagick'" -blur 1,1 ) ^
  output.BMP
 
Output
----------
Output.bmp shows  4 black text  lines ("ImageMagicK") at  4 different
location  (with blur effect).
Line 1 and 4 has same blur attributes "-blur 1,1". (But the effects are
different in output. Why?)
Line 2 and 3 has same blur attributes "-blur 0,8". (But the effects are
different in output. Why?)
and How i can get the same blur effect on line (1 & 4) and (2 & 3)  
 
(Please suggest me)
 
Thanks and Regards
