You can use Points On A Canvas to:
Measure distances between the clicked points. and compare the lines formed by those points. In the Complex Interface the distances are shown between any two points which belong to the same point group. You can easily specify to which point group(s) a point belongs to. A point can belong to as many point groups as you want.
In the Simple Interface you need add the point to the 'Simple Interface Measurements' window first and then press the 'Measurements' button.
Use the Quick Perimeter controls at the top left to find out the distance between any numbers of points.
Make your points stay on top of any visible window by hiding the canvas. To do this, add at least two points to the canvas and make the canvas completely invisible. This way you'll be able to measure anything on your screen (Window -> Make Canvas Transparent and Click through-able).
Compare selected lines. This is available in the Complex Interface (top right button).
Define your own measurement units from scratch or using live calibration.
Load a background image on the canvas then click to add points and see the distances between the clicked points.
Add point based shapes which are shapes drawn on the canvas based on existing points. For example a point based circle has two points: one for the center and one for the radius, a point based ellipse has three points: one for the center, one for the horizontal axis and another one for the vertical axis. There are other shapes like rectangle, square, trapezoid, Bezier curve, and a few others.
Add draggable shapes like circle, rectangle, triangles, etc which can be dragged around the canvas and have their color changed.
Define your own workflows which are steps which tell you where to click next.
Activate the grid-view on the canvas and set the distances between the vertical and horizontal lines.
Specify how the text information for a point is rendered on the canvas. You can use your own words and parameters like: POINT.NAME, POINT.COORD.X, POINT.COORD.Y, POINT.DESCRIPTION.
For example you could use a phrase like the following when rendering the point on the canvas:
The name of this point is: POINT.NAME, the description is: POINT.DESCRIPTION and the coordinates are: X = POINT.COORD.X and Y = POINT.COORD.Y.
If you want us to add more parameters to use when rendering the point, let us know.
Drag the canvas anywhere you want on the screen. To be able to drag the canvas, make sure the "Dragging Enabled" check box is checked.
Set the transparency of the canvas using the scroll bar at the right of the canvas window.
Take snapshots of the entire canvas.
Use the magnifier.
Save the entire canvas (points and background image) so you may load it later.
Change background color for the canvas.
Change the color for the point's draggable controls.
Change the size of the canvas by dragging it from the bottom right corner.
