[l2h] Anti-aliasing problem

[Walter Boehm]

I have the following problem: I want to display my formulas
on a background  with a nonwhite color. So I generated transparent
images with antialiasing turned on. But unfortunately antialiasing
uses the wrong background color. As a result my formulas have
a boundary with white or light gray color. This happens even if
I set \pagecolor{wheat} or something of this type.
Does anybody know how to solve this problem?
Thanky in advance
Walter
