138 Extensions protrusion classes The amount of expansion depends in the shape of the character. Vertical strokes are more sensitive for expansion then horizontal ones. So an ‘o’ can get a different scaling than an ‘m’. As with protrusion we have collected the properties in classes: name vector step factor stretchshrink preset 0.50 1.00 22 quality default 0.50 1.00 22 The smaller the step, the more instances of a font we get, the better it looks, and the larger the files become. it’s best not to use too many stretch and shrink steps. A stretch of 2 and shrink of 2 and step of .25 results in upto 8 instances plus the regular sized one. protrusion vectors We only have one vector: quality: U+00021 0.00 ! 0.20 U+00028 0.05 ( 0.00 U+00029 0.00 ) 0.05 U+0002C 0.00 , 0.70 U+0002D 0.00 - 0.70 U+0002E 0.00 . 0.70 U+0003A 0.00 : 0.50 U+0003B 0.00 ; 0.50 U+0003F 0.00 ? 0.20 U+00041 0.05 A 0.05 U+00046 0.00 F 0.05 U+0004A 0.05 J 0.00 U+0004B 0.00 K 0.05 U+0004C 0.00 L 0.05 U+00054 0.05 T 0.05 U+00056 0.05 V 0.05 U+00057 0.05 W 0.05 an example of expansion U+00058 0.05 X 0.05 U+00059 0.05 Y 0.05 U+0005B 0.05 [ 0.00 U+0005D 0.00 ] 0.05 U+0006B 0.00 k 0.05 U+00072 0.00 r 0.05 U+00074 0.00 t 0.05 U+00076 0.05 v 0.05 U+00077 0.05 w 0.05 U+00078 0.05 x 0.05 U+00079 0.05 y 0.05 U+000A1 0.00 ¡ 0.20 U+000AB 0.50 « 0.50 U+000AD 0.00 0.70 U+000BB 0.50 » 0.50 U+000BF 0.00 ¿ 0.20 U+0060C 0.00 0.70 U+0061B 0.00 0.50 U+0061F 0.00 0.20 U+006D4 0.00 0.70 U+02013 0.00 – 0.30 U+02014 0.00 — 0.20 U+02018 0.70 ‘ 0.70 U+02019 0.00 ’ 0.70 U+0201A 0.70 ‚ 0.00 U+0201B 0.70 ‛ 0.00 U+0201C 0.50 “ 0.50 U+0201D 0.00 ” 0.50 U+0201E 0.50 „ 0.00 U+0201F 0.50 ‟ 0.00 U+02039 0.70 ‹ 0.70 U+0203A 0.70 › 0.70 We use zapf.tex as example text, if only because Hermann Zapf introduced this optimization.

\definefont[MyTestA][Serif*default at 10pt] \definefont[MyTestB][Serif*whatever at 10pt] We use the following example. The results are shown in figure 8.9. The colored text is the protruding one. \startoverlay {\ruledvbox \bgroup \hsize\textwidth \MyTestA \setupalign[normal] \input{tufte} \egroup} {\ruledvbox \bgroup \hsize\textwidth \MyTestB \setupalign[hz,normal] \maincolor \input{tufte} \egroup} \stopoverlay We thrive in information--thick worlds because of our marvelous and everyday capacity to select, edit, single out, structure, highlight, group, pair, merge, harmonize, synthesize, focus, organize, condense, reduce, boil down, choose, categorize, catalog, classify, list, abstract, scan, look into, idealize, isolate, discriminate, distinguish, screen, pigeonhole, pick pickover, over, sort, sort, integrate, blend, blend, inspect, inspect, filter, lump, skip, smooth, chunk, average, approximate, cluster, aggregate, outline, summarize, itemize, review, dip into, flip through, browse, glance into, leaf through, skim, refine, enumerate, glean, synopsize, winnow the wheat from the chaff and separate the sheep from the goats. Figure 8.9 The difference between no expansion and quality expansion. 8.10 Composing This feature is seldom needed but can come in handy for old fonts or when some special language is to be supported. When writing this section I tested this feature with Dejavu and only two additional characters were added: fonts > combining > Ѵ ̏ (U+00476) = Ѵ (U+00474) + ̏ (U+0030F) fonts > combining > ѵ ̏ (U+00477) = ѵ (U+00475) + ̏ (U+0030F) This trace showed up after giving: \enabletrackers 139 Extensions
