IQView or K-Pacs does not show the overlay bitmap if the entry is checked in the programs menu.
What elements have to be there? When adding the following data to the dicom file a 1 bit barcode could be seen on the upper left corner.

Only a few viewers show the bitmap correct e.g. efilm. What information or elements from the overlay tags does K-Pacs or IQView expect so that the bitmap is shown ?
