Several features in ScanImage require user graphical interaction – e.g. selection of point, line, or area – with one of the ScanImage Image Display Figures:
and ROI Addition tools (buttons) on the Main Controls panel- The 4 -- display zoom, display data tip, display histogram, and display statistics – located at bottom of the Image Controls panel
When any of these graphical interaction tools are selected (button pressed), ScanImage determines which Image Display Figure the user should interact with based on the value specified in the Image Controls. There are 5 valid figures to use with these tools: the Channel <1-4> display figures and the Channel Merge display figure.
By default, is set to None. In this case, the user must first click on the desired Image Display Figure (which must be visible). Following this click, the appropriate interaction for the specific tool (i.e. point, line, or area selection) can be executed. If no figure is clicked within 5 seconds of selecting the graphical interaction tool, then the operation is cancelled.
In cases where the user may want to repeatedly employ the same Image Display Figure when using graphical interaction tools, then the can be specified as one of the 5 valid figures for graphical interaction tools. If a figure is specified, the requirement to first click on the target image display figure is removed.
