[scribus] Problem with large exported PDF files

Hi Christoph--  Thanks for the reply.

The original input files are, in total, about 500MB.  They are jpegs. There are about 150 of them.  One per page.  There's no text, just 1 photo per page.  In scribus, I set the the resolution of every photo to about 300dpi.   Scribus properties for each image shows Actual X-DPI and Actual Y-DPI of 300 to 330 depending on the photo.

I figure gs will resample down to 300, so I wasn't too worried about the 330dpi.  I do not know why Scribus makes a 2GB PDF file.  

If there is another way that I should be specifying 300dpi for each image in Scribus, please let me know.

I'm exporting to PDF 1.5 (Acrobat 6).  I've tried setting colors for Screen/Web and Printer.  The Printer option makes even larger PDF files (about 2.5GB as compared to 2GB for screen/web).
