inEllipseAlignment | CoordinateSystem2D* | ||
inColorIds | Hash?Array* | ||
inPalette | PixelArray* | ||
inDrawingStyle | DrawingStyle | ||
inForceRgb | Bool | Filter will convert monochromatic image to RGB if needed | |
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 inEllipses. 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.
