Description

The operation draws an array of regions of interest on the inImage using common drawing parameters for all of them. Regions 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 inRois This will be the primitives to be drawn.
  • Leave the inColors input not set to have all the primitives drawn with random colors. Set a custom array of colors here to decide explicitly how each of the primitives should be drawn.
  • Set inForceRgb to True, if you want to get a 3-channel output regardless of what is on the input.
