Bug ID: 147642
Summary: Equation Conversion Problem From PDF to PPT conversion
with soffice --infilter=impress_pdf_import
--convert-to ppt
Product: LibreOffice
Version: 7.3.0.3 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Description:
Some part of equation ("big" parenthesis and "big" square root) are not well
converted with a PDF to PPT conversion (and also PDF to ODP conversion).
See this question on ask.libreoffice.org:
https://ask.libreoffice.org/t/error-with-soffice-ms-powerpoint-97-filter-conversion/74112
I used the following command line: soffice --infilter=impress_pdf_import
--convert-to ppt myPDFtoconvert.
I precise that the PDF was generated with LaTeX Beamer (I can provide the
Beamer code if necessary).
Steps to Reproduce:
1. Generate a PDF (called "MWE.pdf") using Beamer with the following LaTeX code
and LuaLatex engine (if possible the last LaTeX distribution as Texlive 2021
for exemple):
```
\documentclass{beamer}
\usepackage{amsmath}
\begin{document}
\begin{frame}{Equations}
\begin{subequations}
\begin{align}
{ErrIm}(i) = \frac{abs \left( Im_{Ny_1}(i) - Im_{Ny_2}(i)
\right)}{\frac{ max \left( abs \left( Im_{Ny_1} \right) \right) + max \left(
abs \left( Im_{Ny_2} \right) \right) }{2}} \times 100 \\
{ErrRe}(i) = \frac{abs \left( Re_{Ny_1}(i) - Re_{Ny_2}(i)
\right)}{\frac{ max \left( abs \left( Re_{Ny_1} \right) \right) + max \left(
abs \left( Re_{Ny_2} \right) \right) }{2}} \times 100
\end{align}
\end{subequations}
\begin{subequations}
\begin{align}
S = \sqrt{\frac{1}{N-1}\sum_{i=1}^{N} \lvert A(i) - \mu
\rvert ^2} \\
\text{avec $\mu$ la moyenne de $A$ : \ \ }
\mu = \frac{1}{N}\sum_{i=1}^{N} A(i)
\end{align}
\end{subequations}
\end{frame}
\end{document}
```
2. Convert the PDF with this command line: soffice
--infilter=impress_pdf_import --convert-to ppt MWE.pdf
3. Open the PPT file with Impress or Power Point
Actual Results:
You will see that somme parenthesis are not present in the PPT file ("abs"
function and "max" function) and also the square root after the "S ="
Expected Results:
The PPT should be equivalent to the PDF regarding to the parenthesis and square
root in equations.
Reproducible: Always
User Profile Reset: No
Additional Info:
I use Ubuntu 20.04 LTS on a Windows Subsystem Linux.
I can't check is OpenGL is enabled.
I didn't resetting my UserProfile because this bug was reproduced by a
LibreOffice core developer in this question on ask.libreoffice.org:
