Possible disadvantages

• Limited Advanced Features
  Compared to some commercial OCR solutions, GImageReader may lack some advanced features such as direct cloud storage integration or advanced document layout analysis.
• Dependency on Tesseract
  While Tesseract is a powerful OCR engine, its performance and accuracy can vary depending on the quality of the input image and the language, which can limit the effectiveness of GImageReader in some cases.
• Manual Installation on Linux
  Users may find the installation process on Linux somewhat complicated, particularly if they are not familiar with compiling software from source.

• Customization Options
  The library allows for extensive customization, providing options to modify the layout and design of the PDF, such as margins, headers, and footers.
• HTML to PDF Conversion
  Wicked PDF efficiently converts HTML content to PDF using the powerful wkhtmltopdf tool, allowing developers to leverage their existing HTML/CSS skills.
• Active Community Support
  Being an open-source project, Wicked PDF benefits from an active community that contributes to its improvement and provides support through discussions and shared solutions.
• Embedded Resource Support
  It supports the embedding of images, CSS, and JavaScript in the rendered PDFs, facilitating the creation of dynamic and interactive PDF documents.

Possible disadvantages

• wkhtmltopdf Dependency
  Wicked PDF relies on the wkhtmltopdf external binary, which may require additional installation and configuration on the server to function properly.
• Limited Vendor Support
  As an open-source solution, Wicked PDF may not offer the same level of professional support or SLA guarantees that a proprietary library might provide.
• Complex CSS Handling
  Rendering complex CSS or JavaScript-heavy pages might be challenging due to wkhtmltopdf's limitations or differences in how it interprets styles.
• Performance Overhead
  Generating PDFs using wkhtmltopdf can be resource-intensive, leading to potential performance overheads, especially for large-scale applications generating many PDFs concurrently.
• Cross-Platform Compatibility
  Ensuring consistent behavior across different operating systems can be tricky, as wkhtmltopdf's performance and features vary slightly between platforms.
