as.mask.psp

Convert Line Segment Pattern to Binary Pixel Mask

Description

Converts a line segment pattern to a binary pixel mask by determining which pixels intersect the lines.

Usage

as.mask.psp(x, W=NULL, ...)

Arguments

x

Line segment pattern (object of class "psp").

W

Optional window (object of class "owin") determining the pixel raster.

...

Optional extra arguments passed to as.mask to determine the pixel resolution.

Details

This function converts a line segment pattern to a binary pixel mask by determining which pixels intersect the lines.

The pixel raster is determined by W and the optional arguments .... If W is missing or NULL, it defaults to the window containing x. Then W is converted to a binary pixel mask using as.mask. The arguments ... are passed to as.mask to control the pixel resolution.

Value

A window (object of class "owin") which is a binary pixel mask (type "mask").
