Hitch, are you sureyou are using the term kerning correctly? Kerning works just fine with my H2O using RMDSK and a font that supports kerning.

Really? C'mon. Yes, Jon, i'm sure that I'm using it correctly. Let me ask you this: you kern a font, the way that The Grand Mouse suggests, say, -0.2em. What happens when you change the font sizes, or change the font? If you go from, say, Garamond to Trebuchet? Given that every bloody font has its own kerning tables, (I'm assuming proper foundry fonts, not the vast ocean of cruft you find online that can't spell "kerning," must less set it up for a font), etc. how can that possibly work, across fonts? Seriously, I'm not arguing. If that can work, groovy. But how? Hitch |

But it's the switching of fonts that kills it. Ebooks really need better rendering software for that level of typography. |

There are assumptions in there, however. Assumptions that the relative size, etc. the proportionality, of the fonts, will stay the same, as the font is enlarged. I'm not sure I believe that, not to the degree that is needed, for successful kerning. I also don't know--and this is probably just ignorance, on my part, as I'm not a programmer of the rendering engines--how justification algorithms can (or don't) affect the layout, proportionality, etc. of the fonts. It's one thing for InDesign to do it--a program dedicated to layout--and another for the El Cheapo EReader software to do it, on the fly. And yes, switching fonts is certainly a Kiss of Death. If we set them so that they cannot be overridden, you'll either have unhappy (gruesomely) readers, or retailers, or worse, both. Just saying. Anyway, we probably ought to drift back ON topic, as this isn't what the OP asked. Not that drifting OT is new to Sigil, of course. Hitch |

Outside of the CSS world, "kerning" only refers to custom letterspacing between specific pairs of characters.The "kerning" done by RMDSK is this type of spacing and it requires that the font file contain a table of character pairs and their associated spacing adjustment. Global spacing changes across a range of characters is "tracking" in the general electronic typesetting world. With metal type, "kerning" is limited to custom reduction of spacing between specific character pair and is not the appropriate term when there is an increase in the spacing, whether between specific pairs or a range of characters. There are similar varying definitions of "font" between the 3 worlds. |

To its credit, Apache OpenOffice Writer gets kerning v. tracking right. |

Just an aside, a large first letter can botch ligatures if the first letter and the next make up a ligature pair.

If you can't control the fonts, it's a possible KOD. (Kiss O'Death). (We recently had an experience with a book showing up, with ligature issues, and I'm still yanking my hair out of my noggin.) We never make eBooks with ligatures, excepting fixed-layout. Period. Hitch |

I would have thought that any decent rendering engine would have the sense not to use a ligature if the two letters of the pair had different styles applied to them.
