[Peter Cholak]

Hello,

Can I create png images which have a white blackground and no heavry lines
on the left and bottem edges.

See
http://www.nd.edu/~cholak/abstracts/abstracts.html

for an example of what I do not want.   I would like those 3 png to have a
white background and no lines.

Thanks in advance,
