DrawShapeRegions_TwoColors


Module: FoundationLite

Draws shape regions on an image with two colors, depending on the status of each region.

Applications

Usually: green or red for pass/fail status.
Name Type Description
inImage Image Input image
inRois ShapeRegion?Array?
inRegionAlignment CoordinateSystem2D*
inColorIfTrue Pixel
inColorIfFalse Pixel
inConditions Bool?Array?
inDrawingStyle DrawingStyle
inForceRgb Bool Filter will convert monochromatic image to RGB if needed
outImage Image Output image

Description

The operation draws an array of shape regions 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.
  • 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.

Examples

Example usage of the DrawShapeRegions_TwoColors on an empty image.
