This file shows a few diagrams in .svg format produced without the use of
LaTeX or equivalent.
The diagrams have been adapted from the Circuit_macros
examples in order to test the svg output of dpic.
To generate the equivalent for all the examples, go to the
examples/dpv directory and type "make". Typing "make examplesDPVs.html"
produces the selection shown here.
</p>
<p>
Generating svg line
art is straightforward but formatting text is not because TeX, LaTeX,
and related word processors do not produce svg directly. Either
less-sophisticated text formatting must be employed for svg or an
<A HREF="https://en.wikibooks.org/wiki/LaTeX/Export_To_Other_Formats">
intermediate format</A>
such as pdf can be
produced, followed by an additional processing step to convert to svg.
Two possibilities for the latter are
<A HREF="https://www.ctan.org/pkg/dvisvgm">dvisvgm --pdf</A>
and
<A HREF="https://github.com/dawbarton/pdf2svg">pdf2svg</A>.
However, many circuit and similar diagrams intended for the web do not
require sophisticated labels; the examples shown below might
be representative. Compare them to those in
<A HREF="examples.html" TARGET="_blank">examples.html</A>
</p>
<p>
Click on the link to view the source of each diagram.
</p>
<hr>
<p>
There are other issues:
<ul>
<li> The default font face is not specified in all of these diagrams but is
inherited from the enclosing document, so the appearance of labels can
differ depending on the browser. Some of these diagrams set the font at
the beginning of the diagram source.
<li> Diagrams such as these contain text labels
that have to be treated differently from the LaTeX-compatible versions;
for example,
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.
<li> 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 could be defined to exercise some of the media capabilties
of svg. They are subject to change:
<ul>
<li>
<g style="font-family:monospace">svg_font(</g>font-face,nominal size[:dptextratio],textoffset,
dpic commands<g style="font-family:monospace">)</g>:
Change font face, size, textratio and dpic textoffset parameters.
Change font face and dpic <g style="font-family:monospace">textht</g>, <g style="font-family:monospace">dptextratio</g>,
and <g style="font-family:monospace">textoffset</g> parameters.
If arg4 is blank, the font is changed and
requires <g style="font-family:monospace">command "</g>"</g> to cancel the font change.
<br>
Note:
Nominal height = text height in drawing units; actual height =
nominal ht x <g style="font-family:monospace">dptextratio</g>.
<br>
Examples: <br>
<g style="font-family:monospace">svg_font(Times)</g><br>
<g style="font-family:monospace">svg_font(Times,14bp__)</g><br>
<g style="font-family:monospace">svg_font(sans-serif,14bp__:0.71)</g><br>
<g style="font-family:monospace">svg_font(Times,11bp__,1bp__,"text" at A)</g><br>
<g style="font-family:monospace">svg_font(font-family="Times")</g><br>
<g style="font-family:monospace">svg_font(font-family="Times" font-style="italic")</g><br>
<g style="font-family:monospace">svg_font(style="font-family:Times; font-style:italic")</g>
<li><g style="font-family:monospace"> svgfontratio(</g>font name<g style="font-family:monospace">)</g>;
Reasonable <g style="font-family:monospace">dptextratio</g> value for common fonts, used
by <g style="font-family:monospace">svg_font</g>.
<li><g style="font-family:monospace"> svg_tspan(</g>text attributes, text<g style="font-family:monospace">)</g>;
e.g. <g style="font-family:monospace">svg_tspan(font-style="italic" font-size="75%",XYZ)</g>
<li><g style="font-family:monospace"> svg_it(</g>text<g style="font-family:monospace">)</g>: for italics

<li><g style="font-family:monospace"> svg_sf(</g>text<g style="font-family:monospace">)</g>: sans-serif (Helvetica)
<li><g style="font-family:monospace"> svg_norm(</g>text<g style="font-family:monospace">)</g>: for normal text
<li><g style="font-family:monospace"> svg_bf(</g>text<g style="font-family:monospace">)</g>: for bold face
<li><g style="font-family:monospace"> svg_small(</g>text, percent<g style="font-family:monospace">)</g>:
to set a smaller text size, default 66
<li><g style="font-family:monospace"> svg_fsize(</g>text, percent<g style="font-family:monospace">)</g>:

<li><g style="font-family:monospace"> svg_rot(</g>degrees, "text" [at position]<g style="font-family:monospace">)</g>:

<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. Adjustments may also have to be made to
obtain the proper snap-to actions.
<li> Link experiments: Click on the resistor or source of quickDPV
to go to external
files in new windows. Click on "n-port" in NportDPV to replace the diagram
and then "back" to return.
<li> Some of the assumptions used to create this draft may be
naïve.
Comments are welcome.
