Read PNG Images

Read PNG 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 files.

Options

URL Column

Fail on invalid input

If selected, the node will fail during execution if any URL is invalid or points to an invalid PNG file. If unselected, the node will skip these invalid entries and insert a missing value instead. Note that if the parsing fails for all rows, the node will fail in either case.

Replace input column

If selected the node will replaced the selected URL column with the PNG data.

Append new column

If selected the node will append a new column with the given name.
