I wish to modify the spacing in a font such that it matches the look in photoshop. In photoshop I have set the "tracking" to be 200. In FontForge (fonteditor), I can only modify LBearing and Rbearing. Does 200 trackin in photoshop mean 100 LBeargin and 100 Rbearing in FontForge? Or is it 200 LB and 200 RB?
