Howdy,<br>
<br>
The problem is that version 9.51 and later of ghostscript (gs, ps2pdf) treat transparency differently that before so a new option has to be passed to ps2pdf to allow transparency.<br>
<br>
It's not so simple to update things because one never knows what version of ghostscript a person has. Those two engines check the ghostscript version and set the proper option. It is more difficult in other systems.<br></blockquote><div><br></div><div class="gmail_default" style="font-size:small">How do I get this working in Aquamacs?
