Description

Filter draws rectangles on an input image.

If an rectangle dimensions exceeds image size it will not be drawn or will be drawn partially.

To indicate the Rectangle orientation set inDrawingStyle.PointShape and inDrawingStyle.Size.

Rectangle drawn with set orientation indicator inDrawingStyle.PointShape = Circle and inDrawingStyle.Size = 10.

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 inRectangles. 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.
