Comment 3 Yang Su 2008-02-22 21:18:11 UTC 
what's your jpg compression quality setting? The default is set to 75%, try 100%. Also, jpg is lossy, png is recommended.
Comment 4 Peter Lam 2008-02-22 21:48:48 UTC 
yes, using the default 75%. However, in NB6, setting the image quality to 75% is still looking good on the same. See
attached exported jpg file from NB 6.0 (nb6-export-as-jpg-75.jpg) vs a new one from meteora (meteora-export-as-jpg-75.jpg)

Comment 7 Yang Su 2008-02-26 19:12:09 UTC 
there was indeed a bug in float value conversion when setting jpg compression quality value, fixed.
Comment 8 Peter Lam 2008-03-10 18:50:15 UTC 
verified in latest build.
