While a value of 1000 means that the full protrusionas specified in the configuration (see section 5.1) will be used, a value of 500 wouldresult in halving all protrusion factors of the configuration. This might be useful ifyou are generally satisfied with the settings but prefer the margin kerning to beless or more visible (e.g., if you are so proud of being able to use this feature thatyou want everybody to see it, or – to mention a motivation more in compliancewith typographical correctness – if you are using a large font that calls for moremodest protrusion).character, 〈dimension〉characterThis option is described in section 5.1, apropos the command \SetProtrusion. Usewith care.3.3 Font expansion pdfTEX 0.14f | LuaTEX 0.30autotrue, false* trueBeginning with version pdfTEX 1.20 (and with LuaTEX), the expanded instancesof the fonts may be calculated automatically and at run-time instead of the userhaving to prepare the instances in advance. This option is true by default providedthat you are using a TEX engine with this capability and the output mode is PDF;
