imager (version 0.31)

as.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, ...)
"as.cimg"(obj, ...)
"as.cimg"(obj, ...)
"as.cimg"(obj, ...)
"as.cimg"(obj, x = NA, y = NA, z = NA, cc = NA, dim = NULL, ...)
"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)

• numeric: convert numeric
• logical: convert logical
• double: convert double
• vector: convert vector
• 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
