Hello,
This is the “Image writer” Node in “KNIME image processing” extension. When I link it to the Line plot, right click “Image Writer” → “configure”, the error shown as: "No column in spec compatible to ‘ImagPlusValue’ ". Has anyone seen this before? Appreciate.
there are obviously, confusingly different “image” types and KNIME which require different image writers. Try this one instead which should work with the image type you have:
@Zyw you could try and use the combination of nodes in this example to bring an image to PNG. Without that I sometimes had a difficult time extracting images from certain graphic nodes.
