Description

The operation draws an array of circles on the inImage using common drawing parameters for all of them. Circles may exceed the image dimensions - those will be drawn partially or not at all, but the filter execution will succeed.

Hints

  • Connect an image source to the inImage input. Drawing will be done on this image.
    • If you want to draw on an empty background, use EmptyImage filter before.
  • Define inCircles. This will be the primitives to be drawn.
  • Define inConditions with the boolean values indicating the class (usually: OK/NOK) for each input primitive.
  • Set the inColorIfTrue and inColorIfFalse inputs to define the two colors used for drawing.
  • Set inForceRgb to True, if you want to get a 3-channel output regardless of what is on the input.
  • Set inDrawingStyle to control quality, opacity, thickness, filling, point shapes and sizes.

Examples

Description of usage of this filter can be found in examples and tutorial: Mounts (Blob Analysis).
