Input value inCircles Circle2D?Array?
Input value inCircleAlignment CoordinateSystem2D*
Input value inColor Pixel
Input value inDrawingStyle DrawingStyle

Description

The operation draws an array of circles on the inImage using common drawing parameters for all of them. Circles 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 inCircles. This will be the primitives to be drawn.
  • Define inColor. Please note, that on an N-channel image only first N components of the color will be used.
  • 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

Description of usage of this filter can be found in examples and tutorial: Fourier Analysis, Brick destroy (Game), Parallel Image Saving.
