Measurement Consistency

Jaws · 05-10-2024, 01:01 PM

When converting from other formats to epub (especially, but not only, AZW and KFX), there's an annoying issue with inconsistent measurements in the stylesheets. One might see something like this:

Code:

.class16 {
   line-height: 1.2337em;
   text-indent: 1.5em;
   margin: 0 8.177348%
   }

which I find annoying in two respects: Different measurement units, and unpredictable and wildly overprecise measurements imposed on a reflowable text. Are there settings available to

force all measurements to use the same units, and/or

round off/otherwise limit measurements past the decimal point in the stylesheet

during conversion? Or is this something that will always require manually editing the epub stylesheet(s), possibly because there's something in the source files that forces this sort of thing that I'm unaware of?

Units dont come randomnly, they are there because something in the source file was best represented using that particular unit. As for number of decimal points, I dont quite understand what the issue is, am sure you know that 1.5 is really 1.500000000000 so 1.51234567 is the same level of precision as 1.5. THere is no difference in terms of forcing anything on reflowable text between 1.5 and 1.51234567.

Or maybe you just dont like looking at numbers with lots of decimals?
