gEDA-bug: [Bug 795130] Re: "middle" does not refer to the base line of the font

[Peter TB Brett <795130@xxxxxxxxxxxxxxxxxx>]

Okay, this is clearly something we need to think about fixing. Since the
print output and on-screen appearance are at least consistent with each
other at the moment, it's not particularly urgent IMHO.

I think it's reasonable to say that we should aim to keep the appearance
of the reference card (gschem/examples/drawing_primitives.sch) the same
when we fix this.

Title:
  "middle" does not refer to the base line of the font

Status in GPL Electronic Design Automation tools:
  Confirmed

Bug description:
  Currently, the middle option of vertical text alignment refers to the
  middle of the actual string.

  To reproduce:

  1) open gschem

  2) add three separate texts "aaa", "ppp" and "ZZZ" with the accel [at]

  3) put the alignment mark of the strings on the same vertical grid
  line. The base line of the letters coincides now. All three strings
  are on the same height.

  4) set the alignment of the texts to "middle-left".
  The strings will move up by different amounts. As a result, the "ZZZ" is lower and the "ppp" is  higher than the other "aaa".  A similar sub optimum vertical alignment happens with the "upper" options. See the attached screenshot.

  That way, a hyphen is rendered at the same height as an underscore.
  This is clearly not usefull in the context of  pin labels and
  generally symbol design.

  Proposed fix: Align the the text with reference to the base line. The
  "lower" options already do this.
