One bit EPS to PNG with transparent background

[sma71]

I have not been able to figure out how to convert an Adobe Illustrator EPS that is saved with a TIFF (Black and White) preview to a PNG with a transparent background.

If I use the same vector based file from AI but save with a TIFF (8-bit Color) preview with Transparent option enabled, it works fine.

Is there a way to convert from the original format so all of the current files from AI do not need to be resaved with different preview options?

I am running ImageMagick 6.7.3-2 on Mac OSX Lion

same message as your other post. please provide a link to your eps file or ai file so that the PNG developer can see what might be happening

PNG with transparent background I need to be able to achieve with above files: https://docs.google.com/open?id=0B0iw17 ... U4OGRiMDky

Please find another way to convey the images. Google docs
converted them all to PNG. Probably simplest would be to put
them in a tar.gz or .zip and mail it to glennrp at gmail.com
