Display Circle

The Display Circle module provides a way to draw a Circle based on a single point plus radius. The Circle points can be specified as static numbers or accessed from variables in two different formats. Note that the Circle is drawn into the current image and will affect subsequent processing.

Instructions

1. Color - Select the appropriate circle color.

2. Fill - Select if the circle should be filled or empty.

3. Display as Annotation - Select if you want the graphic to be draw after all processing has been completed. If this is NOT selected then the next module in the processing pipeline will see the graphic as if it were part of the image and process it accordingly.

4. Angle - To draw a partial circle or arc you can specify the start and end angles of the circle to be drawn. These values are in degrees. Note that you can use variable expressions to automatically change this value. Angle are only respected on circle drawing and not when filling the circle.

5. Data Source - Select where the circle coordinates and radius should be taken from

Static - specify the integer coordinate and radius for the circle

Variable - specify the 3 variables that contain the coordinate and radius for the circle

List - specify the variable that contains a list of coordinates and radi that specify Circles. The format of the variable should be x1,y1,r1,x2,y2,r2,x3,y3,r3 for each Circle to be drawn.

6. Clear current image - Select to clear the current image and draw the graphics on a black image.
