Density Measurement

Select a Tool

• Click on a button in the toolbar from the first column of the table
or
• Press the key on the keyboard from the last column of the table

Buttons located in the same groups are highlighted with the same color

The simplest tool for dot density measurement - "Density"

• Move the cursor over the image to see the density
• Click to fix the point density

• Click the icon to open the density menu
• Click the icon
• In the appeared window, set the necessary parameters

The following tools allow measuring density in a region of interest

Button	Function	Mouse	Keyboard
"Figures" Group
	Circle	Click at the center of the circle Click at the circle's border Not available in 3D
	Oval	Click on one border of the oval Click on the other border of the oval Not available in 3D
	Rectangle	Click on one vertex of the rectangle Click on the opposite vertex of the rectangle Not available in 3D
"Curves" Group
	Curve	Click on the curve's points, double-click at the end of the curve Right-click on the constructed curve to add a point inside the curve To add a point at the beginning or end of the curve, use the "More" item (see Measurement Manipulations) Click on the first point to close the curve
	Polyline	Click on the vertices of the polygon Click on the first vertex to close the polygon Not available in 3D
"Areas" Group
	Closed Curve	Click at the starting point Move the mouse by clicking on points to draw the area Double-click the last point to finish drawing The area will close
	Closed Polyline	Click at the starting point Move the mouse by clicking on points to draw the area Double-click the last point to finish drawing The area will close
	Closed Pencil, or Freehand Drawing Pen	Click at the starting point Move the mouse to draw the area Click at the ending point The area closes automatically
	"3D Sphere"	See "3D Measurements"
	Volume Construction by Contours	See "3D Measurements"
	Volume Construction by Density	See "Volume Construction by Density"
Create Accumulation Curve		See "Accumulation Curve Construction"

All of these measurements will have area, average density, and average density deviation data displayed next to them:

Density of points through a line

• Construct a line segment, or 2D curve (not applicable for 3D measurements)
• Click the "More" button near the measurement result
• Click the down arrow to open additional menu items
• Click the "Density through a line" item
• A separate window will appear with a histogram showing densities of points:

  

• To cancel a measurement during construction, right-click
• To cancel the measurement construction and return to the default tool, press the key on the keyboard
