Introduction

LaTeX is a powerful document preparation system widely used in academia and research for creating high-quality documents. MiKTeX is a popular distribution of LaTeX for Windows, providing a comprehensive set of tools for typesetting and compiling LaTeX documents. However, updating MiKTeX can sometimes lead to unexpected errors, especially when using specific packages or commands. In this article, we will discuss the issue of the "(\pdfsetmatrix): Unrecognized format" error in landscape figures after updating MiKTeX.

Understanding the Error

The "(\pdfsetmatrix): Unrecognized format" error typically occurs when trying to compile a LaTeX document that uses the landscape package to rotate figures or tables. This error is usually triggered by the pdfsetmatrix command, which is used to set the transformation matrix for the current page. However, after updating MiKTeX, this command may become unrecognized, leading to the error.

Causes of the Error

There are several possible causes of the "(\pdfsetmatrix): Unrecognized format" error in landscape figures after updating MiKTeX:

  • Incompatible packages: The landscape package may be incompatible with the updated version of MiKTeX, leading to the error.
  • Missing or outdated packages: The pdfsetmatrix command may be part of a package that is missing or outdated in the updated MiKTeX distribution.
  • Conflicting settings: The updated MiKTeX may have changed the default settings for the pdfsetmatrix command, leading to conflicts with the landscape package.

Troubleshooting the Error

To resolve the "(\pdfsetmatrix): Unrecognized format" error in landscape figures after updating MiKTeX, follow these steps:

Step 1: Update the landscape Package

The first step is to update the landscape package to the latest version. You can do this by running the following command in the MiKTeX console:

mpm --update landscape

This will update the landscape package to the latest version, which may resolve the error.

Step 2: Check for Missing or Outdated Packages

The next step is to check for missing or outdated packages that may be causing the error. You can do this by running the following command in the MiKTeX console:

mpm --list --outdated

This will list all the outdated packages in the MiKTeX distribution. You can then update these packages to the latest version using the following command:

mpm --update <package_name>

Replace <package_name> with the name of the package you want to update.

Step 3: Check for Conflicting Settings

The final step is to check for conflicting settings in the updated MiKTeX distribution. You can do this by checking the pdfsetmatrix command in the MiKTeX console:

kpsewhich -var-value=TEXMFHOME

This will display the path to the TEXMFHOME directory, which contains the user-specific settings for MiKTeX. You can then check the pdfsetmatrix command in this directory to see there are any conflicting settings.
