image.close - Function



Package general
Module images
Tool image


Close the image tool


Synopsis
close()


Returns
T or fail


Description

This function closes the image tool. This means that it detaches the tool from its image file (flushing all the changes first). The image tool is ``null'' after this change (it is not destroyed) and calling any tool function other than open will result in an error.



Example
- im := image('myimage')  # Starts server and creates Image tool
- im.close()              # Closes Image tool
- im.summary()            # `im' is now null, this results in an error.
- im.open('myotherimage') # `im' is valid again
