Sample Color from Image (vuo.image.sample.color)

Retrieves the color of part of an image.

• Image – The image to sample pixel colors from.
• Center – The position, in Vuo Coordinates relative to the image, to retrieve pixel data from.
• Width – The size, in Vuo Coordinates, of the square of pixels from Image that’s examined to produce the output Color. If Width is 0, this node gets the color of just a single pixel from Image.
• Sample Type — How to determine the value for each RGBA component of the output color: the average of all pixels in the square, or the darkest or lightest component, or the darkest or lightest color.

Out-of-bounds coordinates are clamped to the edge of the image. For example, (-3, .2) becomes (-1, .2).

Keywords: RGBA, area, average, box, brighter, brightest, coordinate, darker, darkest, eyedropper, get, grab, lighter, lightest, maximum, minimum, pixel, rectangle, sample, square
