I am doing a beamer latex presentation and I would like to know how is it possible to add directly a svg graphic on it. I know that it is possible to convert the svg file to pdf format and then include it to beamer, but I want to include the svg file directly (without convert it to pdf format).
The code must looks like:
\begin{frame}
\frametitle{Frame SVG example}
\begin{figure}
\includegraphics[\textwidth]{graphic.svg}
\end{figure}
\end{frame}
Thanks in advance!
You can use the SVG package to achieve that. It will convert your .svg on the fly using Inkscape (which needs to be installed on your computer). It will re-export your figures if the .svg file is changed.
A minimal example could look like this:
\documentclass{beamer}
\usepackage{svg}
\setsvg{inkscape = "C:/Program Files/Inkscape/inkscape.exe" -z -D}
\begin{document}
\begin{frame}
\includesvg[width=0.7\textwidth]{path/to/mysvgimage}
\end{frame}
\end{document}
There are some things to consider, such as text formatting and alignment. Have a look at the documentation of the SVG package.
You also need to make sure that your allow latex to call Inkscape with
pdflatex -synctex=1 -interaction=nonstopmode --shell-escape %.tex
or
latex -interaction=nonstopmode --shell-escape %.tex

I want to automate "raster to vector" conversions. PNG to SVG. (most Qs here on SO are the other way around)
I have tried the old command line tool autotrace on Linux, but I could not get it to run. I've tried to install a package, and to compile it from the source. Nope.
Then I've realised that Inkscape has "autotrace" now integrated in its codebase. I'd like to convert simple sketches from PNG to SVG.
And I want to do this in a Bash for-loop , with different autotrace settings (number of passes; ignore Speckles with max X pixels width) etc.
I've tried the "action" command-line option
inkscape --without-gui --actions="file-open:my.png"
and this brings up the small "png bitmap image import" dialog, waiting for me to confirm.
Also I've tried the verb command line option
inkscape --with-gui --verb="FileImport:my.png"
and this opens the large "Select file to import" dialog (ignoring my --verb argument)
At this point I gave up.
I want Inkscape to import a PNG picture, autotrace it with some settings, save it as SVG. Perhaps, beofre saving, duplicate the traced layer, lock the imported background layer, rename the layers from path-12345 to "tracesettings-x-y-z" etc.
(my final goal is to permute the tracing settings, to find good ones for my use-case, but that's not the focus of this question)
Inkscape is using potrace and autotrace to trace bitmap images into vector formats such as SVG and PDF.
Let's assume you have an image: foo.png that you want to trace to SVG using potrace:
First, you need to convert your image to a bitmap format (BMP).
Invoke the potrace command
# I am using ImageMagick convert command to convert PNG to BMP
convert foo.png foo.bmp
# Invoke potrace command with SVG backend
potrace -b svg foo.bmp
The result will be: foo.svg.
I'm trying to edit a vector graphics file from Freepik. The format is EPS and after installing both Inkscape and Ghostscript on Windows, I'm able to open the file with Inkscape. However, Inkscape introduces some weird artifacts (see lines and wrong colors in the picture below).
Side by side comparison, original vector (left) and SVG saved after opening the EPS file in Inkscape (right)
Is there a way to fix this issue?
It's a little difficult to tell, partly because this is a complex illustration and partly because the rendering is a little small. I'd suggest that the circular artefacts are caused by radial fills not being rendered completely.
This could simply be a rendering problem with Inkscape, or it could be that the radial fill has an Extend parameter which isn't being honoured. It could also be a problem calculating a clip.
It's not entirely obvious what you used to render the left hand image, is that Ghostscript ?
Generally I'd say this looks like an Inkscape bug and you should report it as such.
Edit
Reading through the Inkscape FAQ it seems that Inkscape uses SVG as its native format. That's going to mean that an awful lot of PostScript (and PDF) vector objects aren't going to be represented well. Shadings will either have to be rendered to an image or converted into a complex series of SVG primitives.
Following the link on 'How to open EPS files in Windows' from the FAQ suggests to me that EPS files are either rendered to an image or converted to PDF.
You could use Ghostscript to convert the EPS to PDF yourself, and then try loading the PDF into Inkscape to see if you get a better result. You can also open the PDF in, say, Acrobat to see if it looks OK there.
If the PDF looks fine in Acrobat, but not so good in Inkscape, then I'd say that's an Inkscape problem. If the PDF looks poor in Acrobat then that's a Ghostscript problem.
You can then report the problem as a bug to the appropriate site.
It seems that EPS has more capabilities than SVG and that's why some stuff looks weird when converted to PDF/SVG. Specifically, highlights in an EPS file are not properly rendered in an SVG file.
I checked the conversion from EPS to PDF via Ghostscript and the lines are already there, i.e. it's not an Inkscape bug.
Here's the original file to reproduce the problem:
https://www.freepik.com/free-vector/data-processing-factory-isometric-technology_8625296.htm
And here's what it looks like after converting it to PDF: The artifacts are not as noticeable on the PDF file, possibly because Ghostscript converts it with a higher DPI by default
My workaround to be able to edit the file (remove the background) was to:
open the EPS with Inkscape, ungroup the items
delete the background
export it as PNG
then use the PNG as a "mask" on GIMP to edit the JPG file that came together with the EPS.
I've been doing some stuff in Illustrator and I have a problem with saving a project in to SVG file that I open in webbrowser, It just looks different.
And it hapens only in SVG, if I save it to PDF or PNG it looks how it should.
What am I doing wrong?
That's how it looks in Ai
That's how it looks in webbrowser
Here's a link to download rar file with .ai and .svg that I have.
Since all browsers render it the same way, it would seem likely that this is a bug in the AI SVG export filter.
To me it looks like you are applying a blend mode ("Overlay" perhaps?) to the white parts on top of the image. That effect ought to be reproducible using SVG filters, but perhaps AI's exporter doesn't support that yet.
If you are using an "odd" blend mode, try changing it, or reproducing the effect another way.
Individual pixel control needed in identical svg conversion is not possible. SVG creates only specific shapes. The Ai app conversion seems to use opacity to provide the color shades. You could probably tweek opacity and add some svg filters to improve the svg.
Print your design in a . pdf file instead of exporting it directly. Then open the printed .pdf back in Illustrator and export the .svg from this one, it shoud do the trick.
I'm looking to to use ImageMagick to convert an SVG file with text and external fonts to another svg without text, instead have them be shapes or outlines.
Basically, can ImageMagick do the equivalent of Illustrator's "Create Outlines" functions?
I can currently convert the svg to png and all the text and fonts render correctly, but I'm just looking to remove need for the person opening the svg to have the correct fonts installed on their computer.
I believe that your installation of ImageMagick needs to be configured with the the "--with-autotrace" switch and Autotrace needs to be installed. Then a simple conversion command should work:
convert text.png vector.svg
I doubt ImageMagick will do it. What you need to do is load the SVG into an editor like Inkscape. Select the text and then convert it using Path->Object to Path.
Then you can save it and you can distribute it without worrying about the user not having the fonts.
I am trying to modify a SVG file which has a path converted from a text. I want to be able to manipulate it to create Word Art like effects (eg: Wedge, Widen, Curved text etc).
I've tried many options like parsing the file and modifying each point, but the results are bizarre and curves go wild. There is no tool/library to do this kinda stuff to an svg file.
In short, I am looking for a tool like ImageMagick but for svg. Please Help!!!
Inkscape can do some of this I think, also see this writeup by Tavmjong Bah. Inkscape uses a library called lib2geom to do these effects, and there seems to be a python wrapper for that library.
