I've added TIFF preview support and now want to add PICT preview support to EPS files exported by my app (will add WMF support to Windows version).

I simply get a PicHandle to my image and add it to the resource fork of my EPS file as 'PICT' and id of 256. It looks just fine in ResEdit but when I place the EPS file in Word X, I get a blank image (not even the text that says no preview was included). Placing a Photoshop EPS file with a PICT preview in Word looks fine. However, an Illustrator EPS file with PICT preview does not show up in Word.

The documentation from Adobe (partners.adobe.com/asn/developer/pdfs/tn/5002.EPSF_Spec.pdf) us of some help but seems incomplete. For example, it doesn't mention the fact that TIFF previews can't have a pixel depth of more than 8-bit which I figured out on my own. I'm wondering if there are similar limitations with the PICT preview such as it must be 8-bit and a bitmap. Can anyone suggest anything or point me to some better documentation?
