Examples

# Generate some fake image data
fake <- array(
  c(
    as.matrix(rep(c(0.2, 0.4, 0.6), each = 250)),
    as.matrix(rep(c(0.4, 0.7, 0.8), each = 250)),
    as.matrix(rep(c(0.6, 0.1, 0.2), each = 250))
  ),
  dim = c(750, 750, 3)
)

# Inspect it
head(fake)

# Determine if is an rimg object
is.rimg(fake)

# Convert to rimg object and check again
fake2 <- as.rimg(fake)
is.rimg(fake2)
