large PDF files
Why is it that when I create a PDF file from a Freehand MX file, 7.3mb, the PDF file ends up being 16.8mb? I am not doing any compression but I am embeding the fonts. I find it hard to believe that this would cause the file to increase by 9mb. Any suggestions / ideas?

Re: large PDF files
Its impossible to say why your particular file has expanded, but the
following are often the causes:
1. FH files, since FH10, are not only Binary files, but are also compressed
using algorythms similar to those used in ZIP and SIT archives. PDF files
are not compressed and can sometimes be ASCII. ASCII files are larger that
Binary versions.
2. The PDF format is very limited as to what advanced graphic concepts it
understands. Therefore, may advanced objects must be "disassembled" in the
PDF which can make them largers. FH's Lens Fills, Brush Strokes, Vector
Effects, Raster Effects, Graphic Symbols, and Master Pages are all very
effecient advanced graphic constructs that PDF doesn't understand. These
must all be converted to less effecient constructs when output as PDF.
3. The PDF format has limitations on the format of bitmap images. Compressed
bitmap formats like JPEG and PNG are converted to uncompressed formats,
generally TIFF, in the PDF.
The above rules generally apply to all flavors of PostScript output (EPS,
DCS2, PDF, and PS Printing) and to most other metafile export formats (AI,
WMF, EMF, SWF, ...).
