Since the map potentially needed to be redistributed, particularly as a PDF file, the selection of fonts was restricted to just one; we selected Trebuchet MS, which would not need to be embedded in the PDF file, taking up file space, because that font comes with the Microsoft Windows operating systems.

To reduce file size, we avoided using character marker symbols. We did this because exporting to PDF requires the fonts that character marker symbols are based on to be managed by either embedding the font into the PDF (adding file size) or converting the symbol’s geometry to polygons. The option of converting the symbols to polygons is not a good option in this case because that operation converts true curves into straight lines—making for a faceted polygon instead of a circle in this case. Instead, we used a simple marker symbol and avoided the font issue altogether. However, we tested it first and learned that it worked well.

The only other font that we had to deal with was the north arrow font. The north arrow we chose had no curves, so it was now okay to use the convert-markers-to-polygons option in the PDF export dialog box.

By not embedding the text font for the map, not using a font-based character marker symbol for the restaurants, and converting the north arrow to polygons during export to PDF, we were able to reduce the file size from 320Kb to 229Kb, achieving almost a 30 percent reduction. In all cases my testing of the export file size, we used the Compress Vector Graphics option. We further tested the PDF in Adobe Acrobat and used the Reduce File Size save option, and the only information that was further squeezed from this file was the layering information, resulting in a final file size of 204Kb.
