Hello, I’m AiRon, an automated tech support bot
While you wait for one of our customer support representatives, I can help you with your question.

It seems you’re encountering an issue with line spacing when converting a Word document to PDF using the PDFTron Python SDK. This discrepancy in spacing can arise due to differences in how Word and PDF render documents, especially in terms of fonts and layout settings.

Some things you can try:

Ensure that the fonts used in the Word document are available and correctly embedded in the PDF. Missing fonts can cause layout changes.

Check the conversion settings in the PDFTron SDK to see if there are options to maintain the original layout or adjust spacing.

Use the latest version of the SDK to benefit from any improvements or bug fixes related to document conversion.

Try adjusting the resolution and scaling settings during conversion to see if they affect the layout.

Compare the settings and options used in your conversion script with those provided in PDFTron’s documentation and samples.
