ImgPlus to PNG Images

StreamableKNIME Image Types and Nodes version 1.8.3.202103170902 by University of Konstanz

Converts a KNIME Image Processing Image (ImgPlusValue) from KNIME to KNIME PNG Image (PNGImageCell). At least two dimensions must be selected (the image plane). The alpha channel of the resulting PNG is ignored. If there exist more than one images planes, e.g. in a video, then there will be as many PNG Images created as there exist planes (number of time steps in the case of the video).

Options

XY Dimension Selection
Select the dimensions which serve as the image plane (often 'X', 'Y').
Channel Dimension selection
Select the dimension with the color information (often 'channel') or no dimension for grey value images.

Column Selection

Column Creation Mode

Mode how to handle the selected column. The processed column can be added to a new table, appended to the end of the table, or the old column can be replaced by the new result

Column Suffix
A suffix appended to the column name. If "Append" is not selected, it can be left empty.
Column Selection
Selection of the columns to be processed.
