Classic OS Poster Kit produces useless graphic files

[gusp]

I found an old "poster kit" from 1994 and try to run it on OS 10.5.7 with SheepShaver using OS 9.0.4. I got the app off the floppy and installed it but some things don't seem to work (ie patterns always show up plain black).

I'm trying to export the images so I can open them in OS X.

When I save an image, I have the following options:

The first file type BBM is the native format of the poster kit.

The file sizes are very different, from 116 kb to 1,6 MB. I tried to open them in Photoshop or Preview (OS 10.5.7) but they appear to be broken.

Depending on wether I choose TIFF or PICT2, and depending on what Filters I use, the image is either all black or can't be opened at all. For one image Photoshop claimed the bit depth isn't working.
What could be the problem? Is there a way to convert them?

Thanks!

I am unfamiliar with the application. However, pre-Mac OS X files often lack any) file extensions. If you add the wrong suffix -- .bmp instead of .pct for example, current graphics applications will report errors.

Often time if you get info on the file, the file type is displayed. Then you can add the corresponding extension before opening it within an application.

BTW, instead of mousing around with such an archaic application, consider exploring a modern one. This does not require investing in Adobe products. For example, look at Swift Publisher.

Yes I know, I always added the correct file extensions. I was just wondering if the options play any role. I never saw those TIFF options in more recent applications.

Well I only wanted to get some graphics exported from it, sort of for nostalgic reasons, I'm not trying to work actually with it.

But thanks for your help!
