Read Images
Read images from a list of URLs and append
them as a new column. The
URL list is a column in the input table
containing valid URLs (e.g.
file:/tmp/image.png
).
You can use the "List Files" node to scan a directory
containing
*.png or *.svg files. The URLs may also point to *.zip files, in this
case the zip is opened and the first found image of the selected
types is parsed.
Depending of the selected image type an
appropriate
column type is chosen.
