DrawVectors_MultiColor


Module: FoundationLite

Draws vectors at associated initial points on an image with multiple colors.

Name Type Description
Input value inImage Image Input image
Input value inVectors Vector2D?Array?
Input value inInitialPoints Point2D?Array?
Input value inVectorAlignment CoordinateSystem2D*
Input value inColorIds Hash?Array*
Input value inPalette PixelArray*
Input value inDrawingStyle DrawingStyle
Input value inHeadSize Real
Input value inForceRgb Bool Filter will convert monochromatic image to RGB if needed
Output value outImage Image Output image

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 inVectors. This will be the primitives to be drawn.
  • Leave inPalette and inColorIds not set to have all the primitives drawn with random colors. Set a custom palette of colors here to decide explicitly how each of the primitives should be drawn using inColorIds.
  • 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.

Examples

Example usage of the DrawVectors_MultiColor on an empty image.

Errors

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type Description
DomainError Empty inPalette while inVectors has objects to draw in DrawVectors_MultiColor.
DomainError Inconsistent input array sizes in DrawVectors_MultiColor.
DomainError No palette defined with inPalette for specified inColorIds in DrawVectors_MultiColor.
DomainError The sizes inVectors and inColorIds do not match in DrawVectors_MultiColor.

Complexity Level

This filter is available on Advanced Complexity Level.
