Syntax
image_setregion(reg, coord='')
Examples
Example 1
Add a circle, in the physical coordinate system, to the data from the default data set:
>>> image_data()
>>> image_setregion('circle(4234.53,3245.29,46.74)', 'physical')Example 2
Copy the region from the current frame, create a new frame displaying the residuals from data set 'img', and then display the region on it:
>>> r = image_getregion()
>>> image_resid('img', newframe=True)
>>> image_setregion(r)PARAMETERS
The parameters for this function are:
| Parameter | Type information | Definition |
|---|---|---|
| reg | str | The region to display. |
| coord | str, optional | The coordinate system to use. |
