DrawSegments_MultiColor

Advanced

Module: FoundationLite

Draws segments on an image with multiple colors.

Name Type Range Description
inImage Image Input image
inSegments Segment2D?Array?
inSegmentAlignment CoordinateSystem2D*
inColorIds Hash?Array*
inPalette PixelArray*
inDrawingStyle DrawingStyle
inMarkerType MarkerType
inMarkerSize Real 0.0 -
inForceRgb Bool Filter will convert monochromatic image to RGB if needed
outImage Image Output image

Description

The operation draws an array of segments on the inImage using common drawing parameters for all of them. Segments 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 inSegments. 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 DrawSegments_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 inSegments has objects to draw in DrawSegments_MultiColor.
DomainError No palette defined with inPalette for specified inColorIds in DrawSegments_MultiColor.
DomainError The sizes inSegments and inColorIds do not match in DrawSegments_MultiColor.

Complexity Level

This filter is available on Advanced Complexity Level.
