Unable to load picture or PDF file using subfiles and XeLaTeX

Question

I am trying to include diagrams in the tex file using .pdf_tex files using xelatex.

main.tex:

The methodology.tex file containing the .pdf_tex call:

\begin{document}
\begin{figure}
  \def\svgwidth{\linewidth}
  \input{\main/assets/images/xor_data_embedding.pdf_tex}
  \caption{Diagram}
  \end{figure}
\end{document}

Was hoping for a output like this but alas.

But I can not seem to figure out how to solve the issue. It says it can't load the file but I can't seem to figure out why.

Terminal Output:

I do not think I missed placing the xor_data_embedding.* files in their correct folders.

Folder Structure:

.
|
+---out
|       main.aux
|       main.bbl
|       main.blg
|       main.log
|       main.pdf
\---src
    |   main.tex
    +---assets
    |   \---images
    |           xor_data_embedding.pdf
    |           xor_data_embedding.pdf_tex
    \---methodology
            methodology.tex

The diagram was made using Adobe Illustrator and exported into a .svg, then converted into .pdf_tex using Inkscape. The files are here if required.

Any guidance is extremely appreciated.

Answer 1

Why it doesn't find the path when specified directly?

Because there are two different paths: (a) to the image xor_data_embedding.pdf as seen from main.tex, and (b) to the file xor_data_embedding.pdf_tex.

methodology.tex inputs the file ../assets/images/xor_data_embedding.pdf_tex which is able to happily produce a figure as output using xor_data_embedding.pdf sitting its same directory.

There are three possible cases to test:

(1) Run methodology.tex commenting \subfile{methodology/methodology.tex} in main.tex

It will generate methodology.pdf in its own directory using

.././assets/images//xor_data_embedding.pdf' as source.

It does not need \graphicspath{{./assets/images/}} in main.

(2) Run main.tex , now including \subfile{methodology/methodology.tex}

The compiler will run twice, but this is not related with paths or subfiles.

Adding \graphicspath{{./assets/images/}} points main.tex to the figure and it will generate main.pdf in the root directory now using ./assets/images//xor_data_embedding.pdf as source.

(3) Run methodology.tex, including \subfile{methodology/methodology.tex} in main.tex, deleting before all files from the root directory except main.tex.

As before there will be two process with the same result of (2). (only one run if main.aux was kept.)

This is a MWE of main.tex

% Preamble
\documentclass[10pt]{article}
% Packages

\geometry{a4paper, margin = 1in}
\graphicspath{{./assets/images/}} % full path to image xor_data_embedding.pdf

% Document

This is methodology.tex

Note that \fullpathtofile points to the file xor_data_embedding.pdf_tex not to xor_data_embedding.pdf
