#402 Half transparency will not work for Postscript output

[Leon Meier]

When compiling the code below with latex && dvips, the diagonal line does not shine through transparency in the Postscript file. (Compiling with pdflatex gives a PDF file with the diagonal being visible when viewed with gv.) I'd be glad if I could ask you to repair this problem.

Thank you in advance,

Leon
