Conversion of EPS to PDF or Tiff does not maintain transparency

问题

I am trying to convert eps file to pdf file or tiff file using ghostscript but having issues keeping it transparent. When I convert it to png, transparency is maintained but I need to have pdf or tiff for printing purpose. To convert it to PDF, I am using below Arguments:

For PDF

-dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dEPSCrop -sOutputFile=C:\temp\test.pdf
C:\temp\test.eps;

For Tiff

-dNOPAUSE -dBATCH -sDEVICE=tiff32nc -r300 -dEPSCrop -sOutputFile=C:\temp\test.tiff
C:\temp\test.eps;

is there something I am missing or is it not possible to maintain transparancy?

回答1:

EPS cannot contain transparency, its not part of the standard, so I don't really see how it can fail to 'maintain' it....
