docx-mergefields 0.1.3

Replaces fields in docx (Microsoft Office Word) files

Udpates the MAILMERGE fields in Office Open XML (docx) files. Can be used on any system without having to install Microsoft Office Word. Supports Python 3.7 and up. For the moment only the INCLUDEPICTURE fields are supported.

It supports local images, URLs and base64 image encoded strings. Also, it allows the resize of the image both in width and height.

The fields are replaced so afterwards they cannot be updated anymore.

This library uses the excellent python-docx library.

Also, it is better used after mailmerging the INCLUDEPICTURE fields using the docx-mailmerge2 library.

Installation

Installation with pip:

$ pip install docx-mergefields

Usage

Open the file.

from mergefields import MergeFieldsDocument
with MergeFieldsDocument("../documents/mailmerge_doc.docx") as doc:
  doc.transform_fields()
  doc.doc.save("../documents/merged_doc.docx")

Examples

From local file, original size:

{ INCLUDEPICTURE "./filename.jpg" }

From a URL, resize width to the given size, resize height to preserving the aspect ratio:

{ INCLUDEPICTURE "https://www.pngall.com/wp-content/uploads/8/Sample-Watermark-PNG-Image.png" \w 200 }

From a base64 URI, resize both width and height to the given value (aspect ratio is not preserved):

{ INCLUDEPICTURE "data:image/png;base64,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" \w 200 \h 200 }
