[pdftex] PNG transparency problem

[Geoff Russell]

Hi,

The following plain TeX code includes the attached PNG graphic containing
transparency. But the transparency is being lost somewhere. What am
I doing wrong?

Cheers,
Geoff Russell.

\input graphicx
\long\def\place#1#2#3{%
\vbox to 0mm{\kern#2\hbox{\kern#1{#3}}\vss}%
}
Illustration that transparency in a png isn't working.

\place{30mm}{10mm}{\includegraphics[width=30mm]{globe.png}}
\place{30mm}{20mm}{\includegraphics[width=30mm]{globe.png}}
\place{30mm}{30mm}{\includegraphics[width=30mm]{globe.png}}

\bye
