as.cimg: Convert to cimg object

In imager: Image Processing Library Based on 'CImg'

Convert to cimg object

Description

Imager implements various converters that turn your data into cimg objects. If you convert from a vector (which only has a length, and no dimension), either specify dimensions explicitly or some guesswork will be involved. See examples for clarifications.

Usage

as.cimg(obj, ...)

## S3 method for class 'numeric'
as.cimg(obj, ...)

## S3 method for class 'logical'
as.cimg(obj, ...)

## S3 method for class 'double'
as.cimg(obj, ...)

## S3 method for class 'cimg'
as.cimg(obj, ...)

## S3 method for class 'vector'
as.cimg(obj, x = NA, y = NA, z = NA, cc = NA, dim = NULL, ...)

## S3 method for class 'matrix'
as.cimg(obj, ...)

Arguments

obj	an object
...	optional arguments
x	width
y	height
z	depth
cc	spectrum
dim	a vector of dimensions (optional, use instead of xyzcc)

Methods (by class)

• as.cimg(numeric): convert numeric

• as.cimg(logical): convert logical

• as.cimg(double): convert double

• as.cimg(cimg): return object

• as.cimg(vector): convert vector

• as.cimg(matrix): Convert to matrix

Examples

as.cimg(1:100,x=10,y=10) #10x10, grayscale image
as.cimg(rep(1:100,3),x=10,y=10,cc=3) #10x10 RGB
as.cimg(1:100,dim=c(10,10,1,1))
as.cimg(1:100) #Guesses dimensions, warning is issued
as.cimg(rep(1:100,3)) #Guesses dimensions, warning is issued
