But perhaps we might ask why this is useful, and look one step further
to the mechanics of the underlying text rendering in the field
object to
get exactly what we most want. It may be that such additions would
become trivial once RunRev adds independent column alignment to
fields.
Slogging through big blocks of text line by line and/or word by word,
measuring each and adding/subtracting a number of special one-pixel
characters can be quite slow, and not the sort of thing I enjoy
teaching
to newcomers for simple text alignment.
So hopefully instead we can just get the appearance we want just as we
want it at the moment it's rendered. I doesn't hurt to ask. :)
Yes, and we have those text-description languages available now:
postscript (which most of us now experience as PDF) and TeX/LaTeX---
both of which microtype to way (way!) better than a 1-pixel
character. Writing the code for either is (relatively) trivial. So,
given every modern operating system has engines for both, all Rev has
to do is invoke the engines when needed. For example, in addition to
html, one should be able to declare a field postscript or TeX/LaTeX,
put the code, and Rev simply calls the appropriate engine/renderer to
produce it.
A stroke of genius, Dr. Vokey.
I was pondering sub-pixel measurements over dinner this evening, unsure
if even twips would suffice. Then I come back to read your post. Yes
indeed, it would seem the essentials are available for all platforms.
Maybe somewhere down the road (after independent column alignment, of
course <g>), we just might see that sort of text rendering flexibility
in Rev.
