i do: \includegraphics[figure]{figure.pdf}, and the figure appears to be sitting on a black background in a pdflatex/foiltex-generated pdf. is this in fact called a 'background'? can this color be manipulated? i'm using Red Hat 9.0 pdflatex version: 3.14159-14h-released-20010417, foiltex version 2.1.4a -bryan
