pydyf is a low-level PDF generator written in Python and based on PDF specification 1.7. It provides fine-grained control over PDF features such as bookmarks, attachments, links, color spaces, and text capabilities. The library is actively maintained with frequent releases, typically every 1-3 months.

This example demonstrates how to create a basic PDF document, draw a red rectangle on a page, and save it to a file using pydyf.

import pydyf document = pydyf.PDF() draw = pydyf.Stream() # Set the drawing color to red draw.set_color_rgb(1.0, 0.0, 0.0) # Draw a rectangle draw.rectangle(10, 10, 100, 50) draw.fill() # Fill the rectangle # Add a page with the drawing stream document.add_page(pydyf.Dictionary({ 'Type': '/Page', 'MediaBox': pydyf.Array([0, 0, 200, 200]), 'Contents': draw, })) # Write the PDF to a file with open('output.pdf', 'wb') as f: document.write(f)

Debug

Known issues

breakingPython 3.8 and 3.9 are no longer supported. Users must upgrade to Python 3.10 or newer.

fix

Upgrade your Python environment to version 3.10 or later.

affects: >=0.12.0

breakingDeprecated methods `color_space`, `shading`, `text_matrix`, and `transform` have been removed from `pydyf.Stream`.

fix

Refer to the pydyf documentation for alternative, non-deprecated methods for managing colors, shadings, text matrices, and transformations.

affects: >=0.12.0

breakingThe deprecated `version` and `identifier` parameters were removed from `pydyf.PDF.__init__`. Calling `PDF()` with these arguments will now raise a `TypeError`.

fix

Remove the `version` and `identifier` arguments when initializing `pydyf.PDF()`. The constructor now expects only `self` as a positional argument.

affects: >=0.11.0

Errors

Common errors & fixes

TypeError: PDF.__init__() takes 1 positional argument but 3 were given

This error occurs because the `pydyf.PDF` constructor's signature changed in version 0.11.0, removing the `version` and `identifier` positional arguments.

fix

Instantiate `pydyf.PDF()` without any arguments. If you need to set the PDF version, assign it after creation, e.g., `pdf = pydyf.PDF(); pdf.version = '1.7'`.

AttributeError: 'super' object has no attribute 'transform'

This error arises due to breaking API changes in `pydyf` version 0.11.0 and later, where the `transform` method's inheritance or existence changed, affecting libraries that relied on the old API, such as `WeasyPrint` versions prior to 63.0.

fix

Ensure compatibility by either pinning `pydyf<0.11.0` (e.g., `pip install pydyf==0.10.0`) or upgrading downstream libraries (like `WeasyPrint`) to versions compatible with `pydyf>=0.11.0` (e.g., `WeasyPrint>=63.0`).

ModuleNotFoundError: No module named 'pydyf'

The Python interpreter cannot find the `pydyf` package, typically because it has not been installed, the virtual environment is not activated, or there is a misspelling in the import statement.

fix

Install the library using pip: `pip install pydyf`. If using a virtual environment, ensure it is activated before installation and running your script.
