Question 1

How do I add an image to a PDF using Gutenex?

Accepted Answer

Use Gutenex.PDF.Images.load to load the image file, then call add_image and draw_image with positioning controls like translate_x and translate_y, as shown in the alpaca example in the README where an image is embedded with specific coordinates.

Question 2

Gutenex vs PdfGenerator: which should I use for Elixir PDF generation?

Accepted Answer

Gutenex provides low-level, native Elixir control for custom PDF creation with fine-grained details, while PdfGenerator often relies on external tools like wkhtmltopdf for HTML-to-PDF conversion. Choose Gutenex for precise document crafting; PdfGenerator for easier, HTML-based report generation.

Question 3

Does Gutenex support UTF-8 or custom fonts?

Accepted Answer

The README mentions setting standard fonts like Helvetica and Courier, but doesn't explicitly detail UTF-8 support or custom font embedding. You may need to explore the source code or community issues for advanced typography features, as it's a low-level library.

Question 4

How can I generate multi-page PDFs with Gutenex?

Accepted Answer

Multi-page functionality isn't covered in the README; you likely need to manage page creation manually by coordinating drawing commands and possibly using lower-level PDF constructs, since the API focuses on single-page operations in the examples.

Question 5

Is Gutenex suitable for production use in Phoenix apps?

Accepted Answer

Yes, it can be integrated by adding it as a dependency in mix.exs and using the API in controllers or background jobs, but be cautious of missing features like templating and ensure proper error handling for the stateful process management.

Question 6

What are the performance implications of using Gutenex?

Accepted Answer

As a native Elixir library, it should be efficient for PDF generation, but performance depends on document complexity. No benchmarks are provided in the README, so testing with your specific use case, such as generating large reports with images, is recommended.
