how to display an annotation or segmentation automatically

I want to display serveral freehandRio annotationes and segmentationes in a specific image, I have the data, but I don’t know how to display them.

I think it maybe ‘renderToolData’, but I don’t know how to get the renderToolData’s param evt.

I am not sure I completely understand. What do you mean by “I have the data”? You have them as DICOM?

the data means the annotation or segmentation data. For example, the freehandRio annotation has the points data. I want to display the freehand annotation automatically with the points data.

In fact, I want to save the user’s annotation or segmentation. When the user reopen the DICOM, we need show the history annotation or segmentation automatically.
