Introduction

During the conversion process, OneLatex automatically generates placeholders from data associated with images and certain file types (e.g., PNG, JPG, PDF, BIB). These placeholders can be used in the environment definition within the settings.

Here’s an example of how a placeholder is used with the default settings in a figure environment for an picture/image:

For more information and guidance on how to define the text for a figure, see To set the title of the picture, right-click on the picture and select "Alt Text...":.

Special Character Rules for Placeholders

Sanitizing Placeholders of certain placeholers

To ensure smooth processing, OneLatex automatically converts special characters in LaTeX labels and file names:

• nameWithoutSC is intended for LaTeX labels, which must not contain special characters or spaces — otherwise, LaTeX may throw compilation errors during rendering.
• filename is used for file names and must comply with operating system rules. Characters like ä, ß, or / can prevent files from being saved or shared properly.

Special Character Converter Tool

To help you understand this process and test your inputs, we’ve created a converter tool below.

It shows — step by step — how OneLatex automatically processes text inputs for LaTeX labels and file names. This makes the conversion logic transparent, especially if you plan to manually reference these labels or filenames later in your document.
