h1. Click Target Finder

Click Target Finder is a basic node that takes input images and allows the user to

manually select targets on the input image. The image target list is the output of this node.

Because most of its subnodes such as Holde Finder and RasterFinder have the option of skipping

automatic finding, they can perform the job of this base class. Therefore, the node is seldom

used.

Required bindings for recieving images and publishing targets:

<highlights>

<simplelist type="vert">

<member> previous Acquisition or Focuser- (AcquisitionImagePublishEvent) -> ClickTarget

Finder</member>

<member> ClickTargetFinder - (ImageTargetListPublishEvent) -> next Acquisition or

Focuser</member>

<member> ClickTargetFinder - (QueuePublishEvent) -> next Acquisition or Focuser</member>

<member> ClickTargetFinder - (ReferenceTargetListPublishEvent) -> AlignZeroLossPeak or

MeasureDose</member>

</simplelist>

</highlights>

Required bindings for proper waiting among nodes:

<highlights>

<simplelist type="vert">

<member> ClickTargetFinder- (ImageProcessDoneEvent) -> previous Acquisition or

Focuser</member>

<member> next Acquisition or Focuser- (TargetListDoneEvent) -> ClickTargetFinder</member>

</simplelist>

</highlights>

This node only has the ability to display target types and submit (send) new image

targets to another node via the Submit Targets button.

h2.  Settings

*  Allow for user verification of picked holes = When enabled, this feature will

pause and wait for the user to verify whether the correct exposure and focus targets

have been selected after the Hole Finder finished processing the input image.

*  Queue up targets = When enabled, submit targets do not publish them immediately

but to put them in a target list queue.

*  Declare drift when queue submitted= When enabled, force target shift correction

when the queue is submitted. Useful when accurate targeting is needed.
