ckevuru / GraphML-To-Tikz

A simple gui based module to convert from Yed-GraphML to Latex-Tikz.

GraphML To Tikz Converter

The purpose of this module is to convert Yed-GraphML to Tikz format.We provide a simple gui interface to preview the Tikz image and provide productive options for both advanced and simple conversions. A .graphml file generated by Yed editor is given as an input and Tikz code is generated.

Getting Started

The following instructions will allow any user to run our module on their local machine.

Prerequisites

For Windows

https://www.python.org/downloads/

PyQt5 5.12 : This library is required for gui of our module.

pip install PyQt5

MikTex : This latex distribution is required to view the preview of Tikz code generated by our module.

https://miktex.org/download

In MikTex the following packages should be installed by using the MikTex console :

pdflatex
pdfcrop

Perl Active State : This perl library is required for MikTex compilation.

Pdf2Image 1.5.4 : This python library is required for converting the pdf generated by MikTex into an image.

pip install pdf2image

QDarkGraystyle 1.0.2 : This python library is used to set the dark theme for our module.

pip install qdarkgraystyle

For Ubuntu

pip install PyQt5

TexLive : This latex distribution is used for Ubuntu.

sudo apt-get install texlive-latex-base

Pdf2Image 1.5.4 :

Runnnig the program

General

After installing all the dependencies one way to operate the module is cloning the repositiory and using the terminal to change directory to the 'Source' directory and running the following command on both Windows and Ubuntu.

python GrapML2Tikz.py

Another way of execution is using an executable. Below we provide links for executables for both Windows and Ubuntu.

Windows

Download Windows executable here. After extracting from Windows_Gr-To-Tik.zip open GraphML-To-Tikz directory and click on GraphML-To-Tikz.exe to run a standalone executable.

Windows_Gr-To-Tik -> GraphML-To-Tikz -> GraphML-To-Tikz.exe

Ubuntu

In Ubuntu te executable generated by pyinstaller has a very large size. We will update our repository with executable at a future date.

Follow the same instructions as Windows executable to run the file.

How to use?

To generate Tikz using this module :

1. Click on browse button and choose a graphml file or drag-drop a file into the box besides browse.
2. Tikz code is generated and shown in the Tikz poreview box.
3. GraphML code is shown in the right box.
4. The preview of Tikz image is shown in a new window.
5. If changes are made to the same file in yed and the file saved, hit the reload button besides the browse button and the changes will be incorporated.
6. Choose between Simple-Tikz and Adv-Tikz by clicking the respective buttons.
7. Refresh button is used when the changes are made to the code generated in Tikz box and user wants to preview the image.
