Re: gEDA-user: More flexible rotated text for 1.6.0, font-sizes etc..

[joe tarantino <joeft@xxxxxxxxxxxxx>]

   Flipping the anchor at 180 degrees rotation is IMHO unwanted and
   unexpected magic.  I think I remember being annoyed by this in the
   past.  What happens when you do this in a batch mode?  Can it be
   reversed?
   It would be better if the on-screen font size matched the printed
   size.  Legibility of silkscreen would be more predictable.
   I'm surprised the font is bigger than it claims to be.  My experience
   is the other way around because the "font size" sometimes defines the
   "cell size" that the character fits into (accounting for pitch etc.)
   rather than the size of the character itself.
   I'd be leery of automatically bumping the font size if it would make a
   schematic composed if new and old symbols look inconsistent.  If (2)
   addresses this then it may be ok.

     Need to teach the print output to handle it of course, but that
     shouldn't be too hard.
     The only grief comes with the currently magic behaviour at 180
     degrees,
     which basically resets to 0 degrees rotation, and flips the anchor
     point
     to the opposite corner of the text box.
     I'm thinking that it should be possible to seamlessly transform any
     old
     schematic which used a 180 degree rotation on load (based on
     file-format
     version number).
     Font sizes give some grief as well. It would be nice if the
     on-screen
     font size matched the print font - which means that I drop the
     magic
     constant in o_text.c to "1.0" - matching the font's size in points
     to
     the requested font size in the file-format. (The old gEDA font is
     about
     1.3x taller than it claims to be).
     Since auto-magically bumping people's text sizes on load (which
     will no
     doubt include some rounding), seems like an "evil" thing to do, I'm
     considering the idea of adding a couple of adjustment processes:
     1. Within gschem - possibly via some nasty popup dialog / wizard
     when
     you load an old file.
     2. Command line based - so old designs can be (if desired) batch
     updated.
     Or.. we could just declare that we don't really care about updating
     users' schematics. In any case, I'm tempted to bump the shipped
     symbol
     library font sizes - to give consistent before/after on-screen
     rendering.
     Or.. do we accept the on-screen shrinkage, and place greater value
     on
     consistency of .ps printed output from existing schematics?
     Best regards,
