Description Reads the color of any pixel or grabs a section of an image. If no parameters are specified, the entire image is returned. Use the x and y parameters to get the value of one pixel. Get a section of the display window by specifying additional w and h parameters. When getting an image, the x and y parameters define the coordinates for the upper-left corner of the image, regardless of the current imageMode().

If the pixel requested is outside of the image window, black is returned. The numbers returned are scaled according to the current color ranges, but only RGB values are returned by this function. For example, even though you may have drawn a shape with colorMode(HSB), the numbers returned will be in RGB format.

Getting the color of a single pixel with get(x, y) is easy, but not as fast as grabbing the data directly from pixels[]. The equivalent statement to get(x, y) using pixels[] is pixels[y*width+x]. See the reference for pixels[] for more information.
get(x, y)
get(x, y, w, h)
xint: x-coordinate of the pixel
yint: y-coordinate of the pixel
wint: width of pixel rectangle to get
hint: height of pixel rectangle to get
