Initial commit of Inkscape SVG LaTeX + PDF support
Based on Daniel Groger's work of five years ago, with minor changes http://www.mail-archive.com/lyx-devel%40lists.lyx.org/msg169820.html This extends the support for Xfig LaTeX + PDF to a more modern and actively developed vector graphics editor. Embedded Objects manual updated, also to include a workaround for an Inkscape 0.91 bug.

It works very similarly to Xfig support, except that Inkscape is a more
|
||||
modern image editor than Xfig, which uses Scalable Vector Graphics (SVG)
|
||||
as its native format.

\begin_layout Standard
|

LyX will process the image file in much the same way as it does an Xfig
|
||||
image, extracting the text into a separate TeX file for the text strings,
|
||||
and a PDF file for the rest.
|
||||
\end_layout
|
||||
|
||||
\begin_layout Description
|
||||
Warning: Unfortunately the latest version of Inkscape, 0.91, contains a bug:
|
||||
with multi-page PDFs, the TeX file will sometimes reference more pages
|
||||
than the PDF file contains.
|
||||
This is the version that ships with Ubuntu 16.04.
|
||||
Its use with LyX can therefore not be recommended, until the bug is fixed

\begin_inset Foot

|

\begin_layout Plain Layout
|
||||
A workaround for those who have already SVG figures in their document is,
|
||||
to manually do the LaTeX+PDF output from Inkscape, edit the
|
||||
\family typewriter
|
||||
.pdf_tex
|
||||
\family default
|
||||
file to remove the erroneous references, and
|
||||
\family typewriter
|
||||
|
||||
\backslash
|
||||
input
|
||||
\family default
|
||||
it directly into LyX, i.e., not use the external-template mechanism:

||||

|
||||

|
||||

|
||||

|
||||
) was used, which allows you do directly edit the
|
||||
\family typewriter
|
||||
.pdf_tex
|
||||
\family default
|
||||
file in a text editor.
|
||||
The LaTeX output is based on this edited snippet as re-generation from
|
||||
the SVG file has been commented out.

\begin_deeper

\begin_layout Standard
|
||||
The reason why we would use this complicated process at all, like in the
|
||||
case of Xfig, is that it makes the text strings inside the figure of the
|
||||
same font type and attributes as the surrounding text, which looks so much
|
||||
more professional.
|
||||
With Inkscape, even the
|
||||
\emph on
|
||||
size
|
||||
\emph default
|
||||
of the font is taken from the surrounding LaTeX document – in Xfig, you
|
||||
have to set it by hand to be the same.
|
||||
Of course you can always embed LaTeX modifiers like
|
||||
\family typewriter
|
||||
|
||||
\backslash
|
||||
Large
|
||||
\family default
|
||||
,
|
||||
\family typewriter
|
||||
|
||||
\backslash
|
||||
small
|
||||
\family default
|
||||
, etc.
|
||||
into your figure text strings.
