Illustrator CS Exporting Problem

[Kevin_Gale@adobeforums.com]

I'm using Applescript to export individual objects on an Illustrator document to graphic files. The problem I have is that the different export formats do not seem to support the same features.
The features I require are:

a) The graphic file dimensions must be the same as the Illustrator object dimensions

b) The graphic file must contain an alpha channel

If I select JPEG as the format I get feature 'a' but not feature 'b'.
If I select PNG24 as the format I get feature 'b' but not feature 'a'

I could save out the same as a JPEG, convert it to PNG24 and some-how create an alpha channel but this is a long-winded solution.

Is there anything i'm missing or is this a current limitation of Illustrator.

Regards.
Kev.

Have you tried placing a box around the art and creating a crop area then saving as png? It should give you both a and b.

Thanks for your reply.

This works manually but cannot be automated via Applescript.

However, thanks to your suggestion I have been able to solve my problem by creating a transparent box with the same dimensions as the text box, exporting as a png and then removing the box all via Applescript.

Cheers.
