Convert a pixel image to a data frame

# S3 method for im
as.data.frame(x, ...)

x: A pixel image (object of class "im").
…: Further arguments passed to as.data.frame.default to determine the row names and other features.

This function takes the pixel image x and returns a data frame with three columns containing the pixel coordinates and the pixel values.

The data frame entries are automatically sorted in increasing order of the x coordinate (and in increasing order of y within x).

A data frame.

# NOT RUN {
   # artificial image
   Z <- setcov(square(1))

   Y <- as.data.frame(Z)

   head(Y)
# }
