Point And Shoot

The Point and Shoot View allows you to select specific points on an image (see Figure 1).

 

Use Point and Shoot to capture an image and/or collect a force curve for every point you designate. When you click a point on an image, a crosshair (+) marks the location. You can designate individual points, or use the tools in the Point and Shoot View to assign multiple points simultaneously.

M/R/Capture—Select points of interest. Software will automatically ramp each point and capture a ramp/force curve.

Line Parameters

Draw a line to select specific points on an image.

Point Number—Number of points in the line.

Spacing—The distance in nm between each point. All points are equidistant.

Clear Path—This button clears the current line and associated points.

Convert to Points—Places a + in the location of each point in the line. The line disappears.

Box Parameters

Draw a box in the area you want to place a group of points. You can use the parameters below to create a grid of points.

Row Number—Designates the number of rows of points in the grid.

Column Number—Designates the number of columns of points in the grid.

Row Space (nm)—Designates the distance in nm between each row of the box.

Col Space (nm)—Designates the distance in nm between each column of the box.

Clear Path—This button clears the current box and associated points.

Convert to Points—Places a + in the location of each point in the grid. The box disappears.

HSDC Parameters Refer to thePoint And Shoot section in High Speed Data Capture

Clear All Marks

Removes all user-defined marks from the Point and Shoot image.

Save Marked List..

Save the marks on the image as Path Files (*.psm).

Load Marked List...

Opens and loads a previously saved Path File (*.psm) which contains marks on a Point and Shoot image.

Note: If there are points on the image prior to selecting this option, when this button is selected the saved marks will appear in addition to the previous marks.

 

Two options are available for moving, in XY, from one point to another:

  1. XY move on surface: Off—Move with tip at home (lift) height.
  2. XY move on surface: Enabled—Move on surface with Z feedback on. See Figure 2.
