Re: [PyX-user] error, paperformat

[André W. <wo...@us...>]

Hi René,

change "brochure.append(page)" to "brochure.append(document.page(page))".

A canvas is not a page, and cannot be inserted into a document without wrapping it in a page object.

The "writePDFfile" and similar methods of a canvas are just convenience methods to directly save a canvas into a file for a rather common use case. When creating documents yourself (for example for multiple page documents), you need to properly (i.e. manually) create pages and insert those into a document. Its just the way it is ...

Best,


André
