Trying to use <Image> causes IconFactory._get_pixbuf_url() error

On Tryton 7.6.6, I am trying to display an image like this:

<image type="url" name="/some/path/filename.jpg" size="200"/>

But I get:

File "dev/venv/lib/python3.13/site-packages/tryton/gui/window/view_form/view/list.py", line 1128, in __sig_switch
    if not self.screen.row_activate() and self.children_field:

           ~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^

TypeError: IconFactory._get_pixbuf_url() takes from 2 to 3 positional arguments but 4 were given

(Note that I abbreviated the file paths for readability.)

I tried adding the size and url_size parameters, but that did not help. What am I missing here?

The name attribute must be the name of a fields.Binary that stores the image data or the name of any images already present in the tryton/data/pixmaps/tryton/ folder (if the type is url it is a path relative to the server URL).

3

That I understood. But I thought by setting the type to url I could display arbitrary image files. Is that not the case?

4

Only images served by the trytond server (at least from the same URL).

Thanks. I now implemented a field that serves the image in question, this works splendidly.
