Overlay > Flatten changes grey values

[foxtango]

Hi,
I start with an 16-bit image. The histogram ranges from 21278 to 65535.
Then I add a scale bar. Its grey value is well within the range of the
image. To add the scale bar to the image I make: Image > Overlay > Flatten.
The histogram of the new image ranges from 0 to 255. How can I add the
scale bar and preserve the original grey values of the image?
Thank you, Thomas Fischer

Greetings Thomas,

perhaps you try it the standard way (Analyze >> Tools >> Scale Bar...).

Paragraph: 0.14.6 Scale Bar…

Best
