> Does kerning influence the width of a string ? What you don't see is what you don't get. That is, PDF has no native kerning support at all. If you want kerning, you do it by adjusting the position of characters in any appropriate way. > It is clear > that kerning > influences glyph positioning, but the viewer application > could (try to) > compensate for that in order to keep the string width constant (by > applying an extra scale factor). No, kerning has no effect or impact here. Because substitution fonts are the same width, kerning atrocities are mostly avoided. That is, what was once carefully kerned should not now collide, much. However, if one cares about typography enough to kern, one should probably embed fonts too. > If the viewer application doesn't compenstate the string width for > effects of kerning, we have a problem, because the viewer application > has no way to know the kerning tables of the missing font on font > substitution, so it doesn't know the original string width either. There are no kerning tables in a PDF, whether fonts are embedded or not. Aandi To change your subscription: http://www.pdfzone.com/discussions/lists-pdfdev.html
