This is a common problem with gradients in PDF files. The ones exported from OpenOffice do that as well. What happens is that every rectangle "step" of the gradient has an antialiased edge, and so you end up with a two anti-aliased edges forming a lighter-coloured gap between the rectangles. Programs that export gradients in a more overlapped fashion (first step full width of of object, next width-1, next width-2) avoid this problem altogether. As an aside, does anyone know of any software that actually uses gradients as specified fill methods from the PDF format? --Pat _______________________________________________ Evince-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/evince-list
