Add an optional parameter to pictureTool() to specify the zoom level #69
Description
Currently pictureTool() has one parameter, the picture to be displayed. Once displayed, the display window has a "zoom" command that allows you to enlarge or decrease the size of the image displayed. Currently, the image is displayed at the default 100% level.
This enhancement request is to add a second parameter that will be optional and allow the specification of a zoom level at initial display of the image. The behavior would be as follows.
- If the new parameter is not provided, then pictureTool() should behave as it currently does, displaying the image at the 100% level.
- If the new parameter is provided, then pictureTool() should display the image at the level indicated by the parameter value.
-- Note: the parameter value should be validated against the current zoom level options, and return an error if the requested level is not available.
