Bug? Converted file FAR larger than before

[jhw]

We are using ImageMagick called from FlexPLM . After upgrading a subversion and installing a new version of ImageMagick,
we find that AdobeIllustrator *.ai files are FAR larger that with the previous version of Imagemagick.
Often by 200%.

New:
Version: ImageMagick 6.7.6-5 2012-04-24 Q16 http://www.imagemagick.org

Old:

Copyright: Copyright (C) 1999-2006 ImageMagick Studio LLC

converted file:
$ file "KDSS1345892 LS A-line Pocket Tee.ai"
KDSS1345892 LS A-line Pocket Tee.ai: PDF document, version 1.5

A different source file:
file "27228 AF Butterfly scoop splice 1pc swimsuit callouts.ai"
27228 AF Butterfly scoop splice 1pc swimsuit callouts.ai: PDF document, version 1.5

I do not readily have a before and after file.
If additional information would be useful please instruct me as to what is needed.

It could be a lot of things. Can you at least send your two output images or use identify -verbose yourimage on each of them and show us that information. What format are you using for your output images? It is possible that you are creating the old image as 8-bit color and the new image as 24-bit color. Look at the colorspace and type information at the top of the verbose information. Also what was your exact command.

Note a lot has changed since 6.2.8 (which is about 480 versions old) and you may need to set some additional options in your command line.
