<p>
These diagrams have been adapted from the Circuit_macros examples in
order to test the <em>experimental</em> svg output of dpic.
Generating the line art is relatively straightforward, but
the labeling is not created by a text processor and therefore must be
more basic.  Some of these diagrams might benefit from a little more
tweaking of fonts and labels.
</p>
<p>
These examples conform to the latest dpic, which has changed the
treatment of text sizing.  That is, "Text" ht y sets the true height
of SVG text to y rather than the nominal height as previously.
</p>
<p>
There are a number of other issues:
<ul>
  <li> Embedding .svg files in html documents with the &lt;embed&gt; or
    &lt;object&gt; tag seems to be a perennial issue.
  <li> This file has been tested mainly by using Firefox.
   Chrome also seems to work well with two issues detected to date:
   a difference handling color fills and text links in svg.
  <li> The Adobe reader apparently requires a line of the form
  <br> &lt;embed src="figure.svg" width="x" height="y" type="image/svg+xml"
     /&gt;
   This means that the html file has to contain dimension
   information for each figure, whereas Firefox can
   determine the figure size
   from the &lt;svg ... object.  Currently, dpic includes a comment line
   giving reasonable dimensions in pixels but this has to be insterted into
   the &lt;embed or &lt;object line.  A makefile does it easily but
   otherwise this could be tedious.
  <li> The font face is not specified by default in these diagrams but is
   inherited from the enclosing document.  The default appearance of labels can
   differ according to the browser.
  <li> The &lt;svg tag may require modification
   from the default used for this test.  Dpic might be modified to
   allow the generation of custom headers but that has not yet been done.
  <li> Diagrams such as these contain text labels
   that have to be treated differently from the LaTeX-compatible versions.
   Apparently there is no direct way to know the bounding box of arbitrary svg
   text.
   <!-- text, as discussed
   <a href="http://www.aditus.nu/jpgraph/jpg_svg.php" TARGET="_blank">here,</a>
   for example. -->
   Consequently, text placement is approximate and may require
   manual adjustment.
   Rather than patch the original source files for svg production, edited copies
   have been used.  The configuration file svg.m4 read by m4
   prior to libcct.m4 contains the following macros defined for svg.
   Others should be defined to exercise some of the media capabilties of svg.
   They are subject to change:
  <ul>
    <li>
      m4tt`'svg_font(</g>font-face,height,textoffset,dpic commands`'m4tt)</g>:
         Change font face, size, and dpic textoffset parameter.
         If arg4 is blank, the font is changed and
         requires m4tt`'command "&lt;/g&gt;"</g> to cancel the font change.
         Examples: <br>
         m4tt`'svg_font(Times)</g><br>
         m4tt`'svg_font(Times,11bp__,1bp__,"text" at A)</g><br>
         m4tt`'svg_font(font-family="Times")</g><br>
         m4tt`'svg_font(font-family="Times" font-style="italic")</g><br>
         m4tt`'svg_font(style="font-family:Times; font-style:italic")</g>
    <li>m4tt svg_tspan(</g>text attributes`'m4tt)</g>;
      e.g. m4tt`'svg_tspan(font-style="italic" font-size="75%")</g>
    <li>m4tt svg_it(</g>text`'m4tt)</g>: for italics
    <li>m4tt svg_tt(</g>text`'m4tt)</g>: for monospace (courier)
    <li>m4tt svg_norm(</g>text`'m4tt)</g>: for normal text
    <li>m4tt svg_bf(</g>text`'m4tt)</g>: for bold face
    <li>m4tt svg_small(</g>text, percent`'m4tt)</g>:
        to set a smaller text size, default 66
    <li>m4tt svg_fsize(</g>text, percent`'m4tt)</g>:
        for setting larger or smaller text size, default 100
    <li>m4tt svg_sub(</g>text, size percent, y displ, x displ`'m4tt)</g>:
        subscript
    <li>m4tt svg_sup(</g>text, size percent, y displ, x displ`'m4tt)</g>:
        superscript
    <li>m4tt svg_symbol(</g>text`'m4tt)</g>: allow quoted pound sign in text,
          e.g., m4tt`'svg_symbol(10&&#96;&#35;&#39;176;)</g> produces 10&#176;
    <li>m4tt svgLink(</g>URL, drawing object, m4tt[B])</g>:
      link to external file using
      &lt;a xlink:href=...&gt;...&lt;/a&gt; (default is
      m4tt`'target="_blank"</g> unless
      arg 3 = B)
    <li>m4tt svgLinkString</g> as above but for strings attached to objects
    <li> Greek and other symbols:

  <li> Inkscape: It may be efficient to define elements by macro and to
    place them using a WYSIWYG graphics editor.  A draft page intended
    for Inkscape is included.  A reasonable variety of elements is defined
    but many more could be added and they should be customized for
    particular applications.
  <li> Link experiments: Click on the resistor or source of quickSVG
    to go to external
   files in new windows.  Click on "n-port" in NportSVG to replace the diagram
   and then "back" to return.
  <li> Some of the assumptions used to create this draft may be naive.  Comments
   are welcome.
