Is there a way to render images that are stored in Blob fields in for exampel a database? It is straightforward to pull up the columns with the databse connector and reader nodes, but the Blob field does not render the images stored in the database.
you can read/write png images from/to dbs by using the Binary Object nodes available via the File Handling extension in KNIME. Using these nodes you can convert a KNIME Image into a binary object which you can then write into the database and back again. See the attached workflow for an example.
Just what I needed, works like a charm!
Many thanks for your swift reply!
I'm happy to be of help. I have also uploaded the workflow to the KNIME Example server where you can find it in the 004_Database section.
