Is it normal for labels to triple the file size of an exported PDF?
I have a moderately complex map consisting of a raster background with a few thousand polyline features overlaid (roadway network). Exporting this to PDF produces a <10 MB file.
When I enable a separate layer contains labels, and re-export, the file-size bloats to over 20MB. These are just basic labels consisting of a white circle with a number inside.
Here's a screenshot of a section of the map with and without labels.
How does a few hundred (at most) labels increase the file-size by that much?!
Thanks in advance for any advice on reducing the bloat due to labeling.
