Transform Manager¶

The Transform Manager handles all shift corrections that need to be done after drift is
declared. The class will be expand to do transformation other than shift in the future.

By the request of an Acquisition Node, the transform manager reaquires ancestors of the
target that requires transformation in order to create the transformed target.

Any acquisition or focuser node that need target correction requires two
bindings.

<simplelist type="vert">
<member> AcquisitionNode or FocuserNode - (TransformTargetEvent) >
TransformManagerNode</member>
<member> TransformManagerNode(TransformTargetDoneEvent) -> AcquisitionNode or
FocuserNode</member>
</simplelist>

For TransformManager to change presets, two bindings are needed:

<simplelist type="vert">
<member> TransformManagerNode - (ChangePresetEvent) -> PresetsManagerNode</member>
<member> PresetsManagerNode -(PresetChangedEvent) -> TransformManagerNode</member>
</simplelist>

</highlights>

Settings¶

• Minimal Magnification = 300. This setting sets a lower limit to the ancestor image
  reacquisition. It can be set to prevent going down to a magnification where the
  objective aperture inserted after the original image was acquired prevents correlation
  between the reaquired image (with aperture) and the original (without aperture).
  Alternatively, it can be set to prevent the reacquisition that uses the LM mode.

Toolbar¶

• Declare Drift = force the Transform Manager to start drift correction
  sequence.
