DrawBoxes_Palette


Draws boxes on an image with multiple colors.

Name Type Range Description
inImage Image Input image
inBoxes Box?Array?
inColors PixelArray*
inOpacity Real 0.0 - 1.0
inForceRgb Bool Filter will convert monochromatic image to RGB if needed
outImage Image Output image

Description

The operation draws an array of boxes on the inImage using common drawing parameters for all of them. Boxes may exceed the image dimensions - those will be drawn partially or not at all, but the filter execution will succeed. Note that drawing is conducted in a pixel-precise way as the Box type is pixel-precise.

Hints

  • If you want to draw on an empty background, use EmptyImage filter before.
  • Define inBoxes. This will be the primitives to be drawn.
  • Leave the inColors input not set to have all the primitives drawn with random colors. Set a custom array of colors here to decide explicitly how each of the primitives should be drawn.
  • Set inForceRgb to True, if you want to get a 3-channel output regardless of what is on the input.
