Hi, If I compare <text:p style-name= styleA >AB<text:span style-name= styleB >CD<text:span style-name= styleA >EF</text:span>GH</text:span>IJ</text:p> with <text:p style-name= styleA >AB<text:span style-name= styleB >CD</text:span><text:span style-name= styleA >EF</text:span><text:span style-name= styleB >GH</text:span>IJ</text:p> where styleA includes style:letter-kerning=TRUE and styleB includes style:letter-kerning=FALSE Then I would think that in the first case there is no letter kerning between D and E but in the second case there is letter kerning between D and E.

Hi Michael, I am just working from the ODF Standard and was looking for a property that does not just affect a single character. (In Gnumeric you cannot specify kerning between characters, therefore so far I have not yet to worry about implementation of this.)

hi Andreas, i found the attributes you are looking for :) 20.367 style:text-combine 20.385 style:text-rotation-angle these work in a similar way to the proposed text range box / text portion box / whatever it will be called: consecutive spans with the same value get combined into one 2-lines or rotated of course the specification doesn't currently say that this is the case... regards, michael On 01.03.21 20:47, Andreas J Guelzow wrote: Hi Michael, I am just working from the ODF Standard and was looking for a property that does not just affect a single character.
