egg.pixel.data: Extract egg pixel data

In eggs: Distances and areas on the surface of an egg

Description

Extracts egg pixels from the current image

Usage

egg.pixel.data(egg.image, egg, lower.theta = 0, upper.theta = pi,
  lower.phi = 0, upper.phi = pi)

Arguments

egg.image	a raster image of an egg
egg	an object of class egg.fit
lower.theta	the lower limit from which to extract pixels around the horizontal axis
upper.theta	the upper limit from which to extract pixels around the horizontal axis
lower.phi	the lower limit from which to extract pixels around the vertical axis
upper.phi	the upper limit from which to extract pixels around the vertical axis

Value

An object of class egg.pixels containing the speherical coordinates (coords), colour (col) and corrected size (pixel.size) of each pixel

Examples

## Not run: 
# Determine egg shape and plot
egg.image(egg)
fit = egg.fit()
egg.plot(fit, lwd = 3, col = "red")

# Extract the data of all pixels
px = egg.pixel.data(egg, fit)

## End(Not run)
