Attach (recommended) or Link to PDF file here:

slice2.pdf

Configuration:

• Web browser and its version: Firefox 68.0.1 and Google Chrome 76.0.3809.87
• Operating system and its version: macOS High Sierra 10.13.6（17G8030）
• PDF.js version: 2.2.228 beta
• Is a browser extension: No

Steps to reproduce the problem:

1. Load the attached pdf file, from_pdftex.pdf, with PDF.js.
2. Figure 1 is blank.

What is the expected behavior? (add screenshot)

Figure 1 should be displayed as Adobe Reader displays.

• The pdf file, from_pdftex.pdf, is generated with pdflatex.
• The figure, slice2.pdf, included in the pdf file is a pdf file created with Affinity Designer.
• First reported by @rubendsa at James-Yu/LaTeX-Workshop/issues/1577.
• Notice that PDF.js can display slice2.pdf itself.

A source TeX file:

\documentclass[12pt]{article}
\usepackage{graphicx}

\begin{document}

\begin{figure}[h]
\begin{center}
\includegraphics[height=1in]{slice2.pdf}
\caption{\textit{Locations of the neutral point ($X_{NP}$) and center of gravity ($X_{CG})$ of an individual wing segment. }}
\label{fig:test2}
\end{center}
\end{figure}

\end{document}

This is fixed by the pull request above.

Please also report it to the maintainer of the PDF generator as well, so that this is fixed properly, since the PDF file is actually corrupt (the /CS entry in the Group dictionary points to a non-existent object).

Thank you both, also for reporting this. This is fixed by the pull request above.
