My Pathomation comes with a set of tools to annotate and draw on your slides. Besides the annotations you make yourself annotations can also be generated by AI image analysis algorithms, for more details on this function look at section interpreting_ai_results
These can be made at the Slide level, which appear everywhere, or at the Collection level.
See these other articles for videos on making annotations in collections and exporting annotations for use in other programs.

The available tools are listed here:

1. Measurement tool
2. Straight line & measurement tool
3. Arrow & text tool
4. Circle tool
5. Square tool
6. Freehand line and measurement tool
7. Closed freehand tool
8. Text tool
9. Delete selected annotations
10. Delete all annotations

The line tool will show you the length of the line, and the area tools will show the area inside the annotation you have marked out. If you want to make a quick series of distance measurements that do not need to be stored, you can use the measurement tool. A video explanation of this can be viewed at https://youtu.be/AfVNdafwNMw

An illustration of the results can be seen below:

The annotation outline colour (1), body colour (2), line thickness (3) can all be changed. If drawing multiple annotations of the same type, you can toggle recursive drawing (4) which removes the requirement to select the type of annotation each time.

The annotations you make on a slide will persist if you include this slide in a collection, slide box or course.

Annotations can also be created at the level of a collection and will be collection specific, in this way a whole slide image belonging to different collections can be given different visible annotations in each collection.
