[Zope] TTImage improvement (code)

Sun, 05 Mar 2000 01:57:10 -0700

Many thanks to Michael the author of TTImage
for pubishing your Product at zope.org.
You did a great job !

In order to create TTImage instances within DTML-Documents I made
some changes on TTImageClass_add because I got errors due to
empty BasicProps and DestinationURL.
Would be nice if you could include it in your next release.

I´m new with Python and especially with PIL so at the moment it´s 
not so easy for me to fix some further problems with the background
color.
When I set the backgroung color to 0xffffff the background color of the 
result is 0xfcfcfc ... seems to be an color palette problem ...   

Also I was wondering if it is possible to set the background to
transparent ?

I look forward to hearing your thoughts on my changes :-)

regards 
Andreas Heckel
