Usually, like described here, images uploaded into DocAssemble (DA) can be put into the template with the corresponding Jinja2 tag defined in the DA YAML file like:
question: |
Please upload a picture of yourself.
fields:
- Picture: user_picture
datatype: file
If {{ user_picture }} is written somewhere in the docx template, the image will be put there. (see doc)
But how can I influence the size of the image in the later docx file?
There are no Jinja2 filters that are applicable. The only solution I found was that DocAssemble uses the package docxtpl and in the documentation there is a method for replacing docx images:
tpl.replace_pic('dummy_header_pic.jpg','header_pic_i_want.jpg')
But I don't find the right way to call this method from within the DA YAML file. What is best practice to put images with a definded width and height into a docx template with DocAssemble?
You can write {{ user_picture.show(width="2in") }}. For more information about the .show() method, see the documentation for DAFile. This also works in the context of displaying images on the screen.
