R: Convert Spatial Object to Pixel Image

pixellate {spatstat} | R Documentation

## Convert Spatial Object to Pixel Image

### Description

Convert a spatial object to a pixel image by measuring the amount of stuff in each pixel.

### Usage

    pixellate(x, ...)

### Arguments

`x` | Spatial object to be converted. A point pattern (object of class `"ppp"`), a window (object of class `"owin"`), a line segment pattern (object of class `"psp"`), or some other suitable data.
`...` | Arguments passed to methods.

### Details

The function `pixellate` converts a geometrical object `x` into a pixel image, by measuring the amount of `x` that is inside each pixel.

If `x` is a point pattern, `pixellate(x)` counts the number of points of `x` falling in each pixel. If `x` is a window, `pixellate(x)` measures the area of intersection of each pixel with the window.

The function `pixellate` is generic, with methods for point patterns (`pixellate.ppp`), windows (`pixellate.owin`), and line segment patterns (`pixellate.psp`), See the separate documentation for these methods.

The related function `as.im` also converts `x` into a pixel image, but typically measures only the presence or absence of `x` inside each pixel.

### Value

A pixel image (object of class `"im"`).
