Figure Help

[-- Attachment #1.1: Type: text/plain, Size: 419 bytes --]

Hey list,

Two questions. Is it possible to define / declare a figure with one
command instead of having to do something like...

\useexternalfigure[SomeFigure][Images/Figure.svg]
\externalfigure[SomeFigure][width=2.5cm]

Also, how do I shift the figure right a few centimetres in from the left
side?

Sure, \externalfigure[Images/Figure.svg] should do it.

I guess the most direct way would be

\hskip 3cm \externalfigure[Images/Figure.svg]

but other solutions may be more appropriate depending on your overall
requirements.

\externalfigure[Images/Figure.svg][width=2.5cm]

Thanks Hans, but all I see is a grey box with the following in it where
I expected to see the image:

name: dummy
file:
figure:Figure
state: unknown

I've checked the path and it looks correct.

See if it works with a PDF file. SVG support is not 100% -- on MkII it
can only be done using Inkscape for preprocessing, and on MkIV support
is ‘via preprocessing and limited’ according to
http://wiki.contextgarden.net/File_Formats .

Hi,

May be I missed one or the other mail on this topic.
There is indeed support for svg-inclusion in MKIV. In order to be possibly of help I would like you to send a minimal example.

Since I'm also interested in this and fail to get it working, please allow me to provide such an example. The svg-file is taken of the german Wikipedia-article of the svg file format. It includes fonts, I'm not sure if this causes trouble.

Note: When I include the extension in the filename (testimage.svg) I get "!LuaTeX error: cannot find image file 'm_k_i_v_testimage.pdf'" probably due to some failed conversion stuff. If I omit the .svg, I get a dummy frame in the pdf output.

Is write18 enables? Do you have inkscape binary in your PATH?

Well, no and no. And the way I see it, proper svg support should not need a prior conversion to pdf done by an entirely different program.
If I wanted that, I can as well save it as pdf or convert it myself. 

I knew about the detour via inkscape, but I hoped for native support.

So I guess svg is not supported then?

The current implmentation (at least when I looked at it 3 months back) 
called inkscape to convert svg to pdf. IIRC, it is possible to configure 
which program is used to do the conversion, but there is no native 
support. The main reason is that there is no native support in pdftex or 
luatex binaries.

Support for svg can be added in two ways, either linking an svg library 
with the luatex binary or writing an svg to pdf converted in lua.

no, and it would be a typical example of adding something to the engine 
that's bigger than the engine itself which is definitely not on our 
agenda (the leaner the meaner)

also, converting svg runtime and doing that each run is pretty 
inefficient; the mkiv runtime conversion only converts (using inkscape) 
when the file has changed and including a pdf file is pretty fast

(the same is true for png files: the pfd format supports png compression 
which is not the same as embedding png so for some variants it's better 
to convert beforehand so that inclusion is faster)

Hey Hans. I think I figured out why it wasn't displaying properly. I was
putting the figure alias where \externalfigure was expecting the path to
the figure.
