Annotating micrographs with a scale bar

Bastian Asmus


This post describes three of the many possible ways of annotating micrographs with a scale bar: manually, semi-manually and fully automated. Any meaningful micrograph needs a scale as a means of informing us about the size of the documented microscopic structutres. There are two ways possible: Either use the caption to tell us the image width, or annotate the image with a scale bar. The  left image (click!) informs us about the image in an unobtrusive bar at the bottom of the image, the right image shows the solution with the scale bar.

1. Annotating micrographs manually
2. Making scale bars – Using Scientific Image manipulation software ImageJ
3. Annotating micrographs using meta tags and a simple shell script
