Who made the decision to use this particular PDF library?

The decision to choose a specific PDF library is usually made by the development team in collaboration with the technical lead or architect. Factors considered during the selection include:

• Compatibility with the technologies and frameworks used.
• Availability of necessary features (generation, editing, encryption of PDFs).
• Performance and stability.
• License and cost.
• Community and support.

For example, if the project requires PDF generation on the client side, a library with good JavaScript support and a convenient API may be chosen. The decision is made after analyzing requirements and conducting comparative testing of several options.
