PCBLib - Split Files Bloated

Embedded fonts create bloated files, single part PCBLib files that would typically only be ~65K will bloat to 488K in size. 

True Type fonts may be embedded into each PCBLib file created when you run the Library Splitter Wizard.

The Embed True Type Fonts Option can be toggled in your Preferences.

DXP > Preferences > PCB Editor > True Type Fonts

Click to view

 



(Shown above Embed True Type Fonts Option is Enabled)


Steps to investigate and reproduce bloated file behavior:

Check Embed True Type Fonts Option in your preferences.

Note the PcbLib File Size is ~ 423K larger, due to the single instance of the embedded True Type Arial Font.

When a PCBLib is split with the Embed True Type Fonts Option Enabled, the True Type fonts are embedded into each of the split PCBLib files, creating bloated files.
