EPS Preview Converter for Mac

From Mark Fleming:

EPS Preview image translation:
There are three different file format used to store EPS preview image, you can use this translator to convert between them. They are:
1. a preview image are stored in a 'PICT' resource in the resource fork of the Macintosh file. 2. a preview image as a hex dump of the image as postscript comments in the EPSI file. 3. a MS-DOS preview image of a TIFF or Windows Metafile place before or after EPS code. A 24 byte binary header describes the offset and size of the PostScript program and the type of preview image and it's offset and size. Currently this translator will not convert WMF previews.
Note: Preview image are of low resolution usually 72dpi, and B&W or 8bit color.
Macintosh PICT to EPS translation:
This translator also functions as an interface to LaserWriter 8's EPS translation code. It allows you to convert any Macintosh PICT file to an EPS file.
