Question 1

How do I draw a rectangle in a PDF using pdf-canvas?

Accepted Answer

Use the Canvas struct's methods to create and stroke paths. For example, after setting up a canvas, call methods like `rectangle` to define shapes, then stroke or fill them. Check the examples directory in the repository for working code snippets.

Question 2

Can pdf-canvas handle adding images to PDF documents?

Accepted Answer

No, pdf-canvas does not support image embedding. It is focused on vector graphics and text using standard fonts, so for images, you need alternative Rust PDF libraries or custom extensions.

Question 3

Is pdf-canvas better than printpdf for simple Rust PDF generation?

Accepted Answer

pdf-canvas is more minimal and dependency-free, making it lighter for basic tasks. printpdf offers more features like image support and custom fonts but has more dependencies. Choose based on your need for simplicity versus functionality.

Question 4

How to set up pdf-canvas in a Cargo project?

Accepted Answer

Add `pdf-canvas = "*"` to your `Cargo.toml` dependencies. Then, import the crate in Rust code and use the API to create PDFs. The README links to API documentation for detailed guidance and examples.

Question 5

Does pdf-canvas support Unicode or non-Latin characters?

Accepted Answer

Since it only uses the 14 standard PDF fonts, which are limited to Latin character sets, support for Unicode or non-Latin characters is restricted. Consider other libraries for multilingual text rendering.

Question 6

What are the main limitations of pdf-canvas compared to other PDF libraries?

Accepted Answer

The main limitations are no custom font support, no image embedding, and an unstable alpha API. It's best for simple PDFs with basic graphics and text, but not for complex documents or production use.
