[Matplotlib-users] [Fwd: bounding box functionality with text() function]

[Michael H. <mh...@us...>]

I'm reposting this, as it may have gotten lost in other discussions.  I 
think there is possibly a bug in the PNG renderer for TkAgg (which is 
what I think I'm using when I say "matplotlib.use('agg')"), as I get 
different visual results from savefig when saving to EPS and PNG. If 
this isn't a bug, can someone please let me know what I'm doing wrong, 
or point me to a workaround for saving to PNG files?

Thanks,

Mike

I'm having a problem with the bbox keyword to the text() function.  The 
code below, for me, results in one postscript file that looks fine, but 
the PNG file has letters outside of the bounding box for most of the 
words I plot.

I'm using matplotlib '0.98pre' on Mac OS X.

import matplotlib
matplotlib.use('agg')
from pylab import *

x = array([6,7,8,9,10])
y = array([6,7,8,9,10])
fig = figure()
plot(x,y,'rx')
hold('on')
fontdict2 = {'fontweight':'light',
             'color': 'k',
             'fontsize':9}
words = ['Hi','Goodbye','What''s this','Aloha','So long, farewell']
for i in range(0,len(x)):
    tx = x[i]
    ty = y[i]
    word = words[i]
    text(tx,ty,word,fontdict2,bbox={'facecolor':'w'})

savefig('textplot.eps')
savefig('textplot.png')
close(fig)
