DrawRegions_TwoColors


Module: FoundationLite

Draws 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 Range Description
Input value inImage Image Input image
Input value inRegions Region?Array?
Input value inRegionAlignment CoordinateSystem2D*
Input value inColorIfTrue Pixel
Input value inColorIfFalse Pixel
Input value inConditions Bool?Array?
Input value inOpacity Real 0.0 - 1.0
Input value inForceRgb Bool Filter will convert monochromatic image to RGB if needed
Output value outImage Image Output image

Description

The operation draws an array of 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 inRegions. 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 DrawRegions_TwoColors on an empty image.
