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.

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.
